AB  - The texture of food plays a vital role in its overall quality, affecting both sensory experience and functional aspects, such as processing and preservation. To study texture in the field of food science and technology, various analytical methods are used tomeasure mechanical properties such as hardness, cohesiveness, and viscosity. One widely utilized technique for evaluating the texture of solid foods, particularly those with high firmness or brittleness such as dried vegetables, is compression testing. Here, a force is applied to a food sample until it deforms or fractures. In this particular study, dried onions, carrots, and peppers were chosen as test samples to investigate their texture and compression properties. To perform the tests, the researchers employed a Shimadzu AGS-X universal testing machine equipped with a 1 kN load cell capacity. This machine allowed them to compress the samples and measure the force required to achieve a specific deformation. The obtained results revealed that the texture and compression properties of the
dried vegetables were significantly influenced by the specific part of the vegetable being tested. For instance, when examining the dried onions, a notable disparity was observed between the inner and outer parts. The basal plate of the onion, in particular, exhibited much greater hardness compared to the middle portion of the dried onion. Consequently, breaking the sample required a higher compression force. This discovery implies that the texture and compression properties of dried vegetables are closely tied to their inherent characteristics, internal structure, and
composition.

AB  - The evaluation of food texture is an essential aspect of food quality control, directly influencing consumer acceptance and preference. Various methods have been developed to assess food texture, including sensory evaluation, rheological measurements, and instrumental analysis. Among the versatile instruments used for measuring the mechanical properties of food, the universal testing machine (UTM) stands out. Traditionally used in the field of materials science
and engineering, the possibility of applying UTM for evaluating food textures has gained significant attention in recent years. The UTM can perform compression, tension, bending, and shear tests on food samples, providing objective and quantifiable data on their mechanical properties. Compression testing involves measuring the force required to compress a food sample between two plates, shear testing measures the force required to cut through a food sample, while puncture testing measures the force required to puncture a food sample with a probe. This paper reviews the current state-of-the-art of UTM in the evaluation of food textures, including the types of tests that can be performed, the parameters that can be measured, and the challenges and limitations associated with the technique. The potential of utilizing UTMs in the food industry for quality control
and product development, instead of traditional sensory evaluation methods, is discussed, along with its advantages and disadvantages. Overall, UTM represents a promising tool for the objective evaluation of food textures, and further research is needed to optimize its application in this field.

AB  - In Serbia, there are about 400.000 hectares of heavy mechanical composition soil and over 100.000 hectares of soil damaged in 
various ways. Every year, with different degradation processes, new 1.000 hectares of soil are damaged. From the aspect of physical 
properties, soil compaction represents a serious problem that leads to changes in physical-mechanical and water-air properties and is one of 
the main factors of soil degradation. This paper presents the technique of measuring soil compaction on experimental field of 1 hectare using 
a hand-held penetrometer on operating depth 25cm, along with the geographic location of the sampling points. The data obtained in this 
research, the method of collecting, processing and displaying that data suggested certain shortcomings of the application of this method for 
testing soil resistance, as well as the need for a procedure for measuring soil resistance using a continuous method.

AB  - There are many physical and chemical properties of soil that can be measured and 
mapped. Such maps can be very important decision-making tools in precision agriculture. 
However, unlike yield maps and crop scouting maps, all other maps show a lower degree of 
reliability in terms of decision utility. Soil compaction is the most representative feature of the 
production plot from the domain of physical and chemical soil properties. This paper first presents 
an experiment designed to measure soil compaction, and then a mapping of the results in a 
commercial software. The test field with an area of one hectare was reduced to a control limit of 60 
meters in width and 120 meters in length to ensure the uniformity of speed and other parameters. 
The resolution of the draft force measurement as an indicator of soil compaction was 50 Hz. This 
resulted in the existence of missing data on the draft force map itself, because several draft force 
values were related to one spatial coordinate manifested as longitude and latitude. The paper 
further shows the procedure of data smoothing and generation of complete maps without missing 
spatial data.

AB  - Soy is widely used in the production and preparation of various protein nutrients and beverages used in both human and animal nutrition. The technological process of soybean processing is more complex than the processing of other oilseeds and therefore requires more attention. Soybeans have a unique feature among oilseeds that during the growing season, three to five months, they can produce the largest amount of protein of the most favorable amino acid composition used in human and animal nutrition. This paper clearly presents one of the possible technological processes of soybean processing in industrial conditions. Soybean processing technology can be observed from three technological phases within the production plant of the factory. The first technological phase (phase 1) in soybean processing refers to the manipulation and storage of grain until processing. Within this phase, there are the following technological operations: grain reception, grain cleaning, grain drying, and grain storage. The second technological phase (phase 2) is the phase of soybean processing, within which there are technological operations that differ depending on the final product. Phase 2 produces intermediates of soybean flakes and soybean cake. The third phase refers to the final processing of intermediate products, packaging of the final product and its distribution to customers.

AB  - This study consists at the modeling and the application of numerical
methods in order to optimize the performance of a flat-water solar collector under the
meteorological conditions of Mali, particularly in the month of January when the
sunshine is low and hot water consumption significant. The results obtained show that
when the thickness of the glass pane is increased from 2mm to 5mm, the instantaneous
efficiency of the solar collector at the beginning increases from 41.46% to 41.49% with
a maximum solar radiation intensity of 462 W/m2 and an average wind speed of 3.5 m/s.
When the thickness of the absorber is increased from 4mm to 5 mm, the instantaneous
efficiency of the solar collector can reach from 40.64% to 41.65%. When the absorber
thickness reaches 6mm, the instantaneous efficiency of the solar collector decreases from
42.35 to 42.14%. Increasing the thickness of the collector's absorber plate can
significantly improve the collector's instantaneous efficiency. Increasing the thickness of
the lateral side insulation does not contribute to improving the collector's instantaneous
efficiency. When the thickness of the lateral side insulation of the collector increases from
2cm to 8cm, the instantaneous efficiency of the collector increases from 53.13% to
53.0%. When the mass flow rate of the fluid increases from 0.0265 Kg/s to 0.04 kg/s, the
efficiency increases from 53.14% to 59.18%. This study also showed that these
parameters have very little influence on the temperature of the heat transfer fluid.

abstract = "This study consists at the modeling and the application of numerical
methods in order to optimize the performance of a flat-water solar collector under the
meteorological conditions of Mali, particularly in the month of January when the
sunshine is low and hot water consumption significant. The results obtained show that
when the thickness of the glass pane is increased from 2mm to 5mm, the instantaneous
efficiency of the solar collector at the beginning increases from 41.46% to 41.49% with
a maximum solar radiation intensity of 462 W/m2 and an average wind speed of 3.5 m/s.
When the thickness of the absorber is increased from 4mm to 5 mm, the instantaneous
efficiency of the solar collector can reach from 40.64% to 41.65%. When the absorber
thickness reaches 6mm, the instantaneous efficiency of the solar collector decreases from
42.35 to 42.14%. Increasing the thickness of the collector's absorber plate can
significantly improve the collector's instantaneous efficiency. Increasing the thickness of

AB  - The widely recognized insect known as the honey bee (Apis mellifera)
has a beneficial impact on both the environment and human life, making it important to
protect them not just for ecological reasons but also for the economic and social
advancement of countryside regions. Their existence is so essential that the recent
decrease in honey bee hives has caused a growing interest in them. One of the reasons
for bees' decline in population is infestation with a parasite known as Varroa
destructor. In order to effectively treat the V. destructor infestation, it is critical to
monitor the amount of infestation in hives. While there is at present no specific sensor
for this job, continuous and discrete monitoring of hive infection levels as well as other
critical bee colony characteristics, such as temperature and humidity, is wanted. The
use of chemicals by apiarists is a method of controlling the infestation that is the most
common strategy. Substitute tactics include the use of organic compounds, organic
products like essential oils, and biotechnological techniques like mite trapping.
Therefore, successful therapy and preventing harsh chemical use can reduce bee
mortality and economic losses.

AB  - Performing works with the land where a lot of mechanical work is engaged, such as making pits for planting fruit, needs to be mechanized. This replaces human labour with a tractor machine aggregate with an increase in productivity and thus makes the process cheaper. For the proper selection of individual means of mechanization, it is important to determine the optimal 
agrotechnical parameters of their application. Proper selection and use of mechanization tools for planting have a decisive influence on the intensity and progress in cultivation technology. Defining 
energy and exploitation parameters of tractor-machine aggregates during mechanized construction of pits is the subject of this research. The pits are intended for individual planting of 
fruit seedlings as well as the installation of trellis poles. The test results of the tractor-machine aggregate show that the lowest driving force engaged for drilling was achieved in the field and 
was 6.36 kW for the excavated pit with the depth of 885 mm and with a diameter of 520 mm, the number of revolutions of the drill was 93 rpm and drilling was achieved in 27 s. The highest 
driving force for drilling was engaged in field III, which was 30.8 kW for the excavated pit 780 mm deep with a diameter of 490 mm, the number of revolutions of the drill bit was 111 rpm and 
drilling was realized in 30 s. The results obtained in these tests show that the consumption of motor power largely depends on the type of soil, the quality of previous soil preparations and the number of revolutions of the tractor PTO shaft. The time required to move the aggregate from one to the next drilling site is crucially influenced by the terrain configuration, the state of soil preparation and the skill of the tractor driver and auxiliary worker.

AB  - Hay is a bulky part of the meal that is most often used in the winter period of the 
year in all types of ruminants, while the role of hay in the meal of high-milk cows is invaluable. 
The most common way to produce hay is to dry the cut grass on the surface of the land in the field, 
using the energy of the sun. In the process of hay production, there is a reduction of nutrients in 
relation to the green mass, where the achieved yield and quality of hay largely depends on the 
technological operations that are performed during storage. In the baling process, the dried mass 
is exposed to the mechanical treatment of the working elements of the press, as a result of which 
the leaf mass decreases. Loss of leaf mass, which contains a large amount of nutrients, can greatly 
affect the achieved yield and quality of the obtained hay. One of the possibilities to reduce losses is 
the application of "DewPoint" technology, which involves the use of water vapor in the baling 
process. The steam produced by the device is injected into the mass-hay after lifting by the pickup 
device and further until the mass enters the pressing chamber. Mass treatment is achieved by 
injecting steam through a series of nozzles located inside the press. Water vapor is an extremely 
efficient medium for the controlled hydration of hay during the baling process, where 
approximately 450 l of water vapor can be produced from 1 l of water. By applying this 
technology, water consumption is 5-7 l per 1 t of hay, producing 2250-3150 l of water vapor. This 
amount of steam enables efficient treatment of individual plants (tree, leaf) in a mass of 1t to the 
desired humidity level.

AB  - The application of precision agriculture in chemical plant protection enables the 
realization of high yields while preserving natural resources. The quality of chemical applications 
depends on the type of technical system that performs for this job. The task of the technical system 
is to protect the cultivated crop precisely, economically and while preserving the environment, and 
all that depends on the precission and the quality of application of the protective liquid. The use of 
UAV´s in chemical plant protection enables precise application of protective liquid, so their 
application is increasing in the protection of numerous crops. The same trend has been observed 
in field production, where the use of UAV´s is on the rise. The paper compares the exploatational 
and technological characteristics of the field sprayer (FS) and unmanned aerial vehicle (UAV) in 
the chemical protection of wheat. The amount of deposited protective liquid on plants and losses of 
deposited on the surface of the earth were monitored. Using UAV (T4: V = 3 m·s-1
, H = 1 m), the 
amount of protective liquid on the plant was determined to be 0.185 mg·l-1
compared to 0.037 mg·l 1
at FS, while the losses were 0.01 mg·l-1
at FS and 0.085 mg·l-1
at UAV. The presence of Fusarium 
(Fusarium spp.) after chemical protection was analyzed according to the compared technical 
systems and set treatments. It was recorded for 20% higher efficiency in protection against 
Fusarium (Fusarium spp.) using UAV (T5: V = 3 m·s-1
, H = 2 m) compared to FS. The values of 
wheat yield were measured according to the compared technical systems and set treatments, where 
the highest wheat yield was achieved using UAV (T5) with 10,667.7 kg·ha-1
, while using FS, 
14.84% lower yield was achieved. The application of UAV´s in the segment of chemical plant 
protection enables us to effectively protect crops, economical and optimized production, while 
preserving the environment in a way that has been completely new and unknown until now.

AB  - Bee pollen provides proteins, lipids, vitamins and minerals in bee nutrition. Bee 
pollen also has a significant nutritive value as a supplement to human nutrition. Fresh bee pollen 
must be dried in order to reduce water activity for the development of various microorganisms. 
Convective drying is common method for bee pollen dehydration. In this paper, several drying 
temperatures (40, 50 and 60◦C) were investigated during the 3 hours convective hot air drying. 
Several drying models used in literature were fitted to experimentally obtained drying curves in 
order to find most suitable one. The best fit was achieved with Two-term (for 60◦C) and Hii et al. 
(for 40◦C and 50◦C) drying models. The coefficient of determination was the primary criterion for 
selecting the best model to describe the drying curves.

AB  - Red pepper (Capsicum annum) fruits contain high amount of ascorbic acid (vitamin C), which is of 
great importance for human health. The aim of this study was to found how various pretreatments 
and drying methods influence on retention of ascorbic acid in dried pepper. The cultivar “Horgoška 
sweet 6”, often used for the production of paprika, was selected for analysis. Five sets of 
experiments were performed to investigate the effect of the following parameters: pretreatment 
temperature (20 oC, 50 oC, 80 oC), pH value (3, 6.5, 10), additive (0.25% citric acid, 0.25 % 
potassium metabisulfite and 0.25 % citric acid + 0.25 % potassium metabisulfite), ultrasound (off 
and on) and drying method (hot air drying and freeze drying). The initial content of ascorbic acid in 
fresh pepper was 292 mg/100 g dry basis (d.b.) and it was reduced after all pretreatment and after 
drying of pretreated samples. Most of examined pre-drying treatments improve retention of ascorbic 
acid in final dried peppers, except treatments at 80 oC. Our results indicate that temperature and 
drying method were parameters that significantly influenced ascorbic acid content in dried peppers. 
Other parameters were not significant, but had a certain effect on retention of ascorbic acid. The 
best parameters were temperature 20 oC, pH 6.5, citric acid/potassium metabisulfite, without 
applying ultrasound including freeze drying method.

AB  - Drying is one of the primary methods of food preservation in the agro-industry and is a complex and energy-intensive process. In recent years, research in the fields of natural and technical sciences has focused on optimizing the energy requirements of industrial systems to sustainably develop and modernize various technologies. Many researchers deal with drying in the agro-industry, as evidenced by an enviable number of publications on this topic. In recent years, a large number of conferences and round tables on the implementation of energy-efficient technologies have been held in the Republic of Serbia. Conclusions have been adopted that The Republic of Serbia, except for the Law on Energy, has no accompanying regulations that would regulate the designing and constructing of centers for the drying, storage, and processing of agricultural products. Drying is one of the basic technological operations in the food processing industry. Attention was drawn to the extremely high energy consumption of drying plants. Some of the proposed solutions are rationalizing energy consumption at existing plants and adopting new, more economical plants based on new technologies. This paper reviews the available literature and research of a large number of international authors dealing with advanced drying technologies, improving the energy efficiency of drying systems and environmental aspects of drying to ensure sustainable development, with a tendency to provide a comprehensive insight into the complexity of the drying process, trends in the development of equipment and technologies, as well as ways to properly select the appropriate technologies depending on the specific feedstock being dried.

AB  - Drying is carried out to prolong the shelf life of food products to reduce 
post-harvest losses by reducing the moisture content present in it. Thin layer drying 
kinetics of okra (Abelmoschus esculentus) has been compared with open sun drying, heat 
pump drying and greenhouse drying with different glazing material such as UV 
Polyethylene sheet and drip lock sheet under passive and active modes. The experimental 
results showed that the reduction in moisture content of okra from 87.65 % to 10% was 
achieved in 16 hours under open sun drying (OSD), 14 hours using UV polyethylene 
sheet greenhouse dryer under passive mode (UVPM), 13 hours under drip lock sheet
greenhouse dryer under passive mode (DLPM) and in UV polyethylene sheet greenhouse 
dryer under active mode (UVAM), 12 hours to achieve the moisture content of 9.3 % 
using drip lock sheet greenhouse dryer under active mode (DLAM) and 8 hours in heat 
pump drying (HPD). The highest dryer efficiency of 38.78% was achieved under HPD 
and 14.15% was achieved under DLAM greenhouse drying. Higher effective moisture 
diffusivity value of 2.09 x 10-10 m
2
/s was achieved in HPD compared to other modes and 
lower effective moisture diffusivity of 1.04 x 10-10 m
2
/s was achieved under open sun 
drying mode in drying okra. Heat Pump dryer had a higher Specific Moisture Extraction 
Rate (SMER) value of 2.60 kg/ kWh compared to other methods of drying. It was found 
that the products dried with minimum drying time in HPD compared to greenhouse 
drying but still in the economic point of view greenhouse drying has low cost.

results showed that the reduction in moisture content of okra from 87.65 % to 10% was 
achieved in 16 hours under open sun drying (OSD), 14 hours using UV polyethylene 
sheet greenhouse dryer under passive mode (UVPM), 13 hours under drip lock sheet
greenhouse dryer under passive mode (DLPM) and in UV polyethylene sheet greenhouse 
dryer under active mode (UVAM), 12 hours to achieve the moisture content of 9.3 % 
using drip lock sheet greenhouse dryer under active mode (DLAM) and 8 hours in heat 
pump drying (HPD). The highest dryer efficiency of 38.78% was achieved under HPD 
and 14.15% was achieved under DLAM greenhouse drying. Higher effective moisture 
diffusivity value of 2.09 x 10-10 m
2
/s was achieved in HPD compared to other modes and 
lower effective moisture diffusivity of 1.04 x 10-10 m
2
/s was achieved under open sun 
drying mode in drying okra. Heat Pump dryer had a higher Specific Moisture Extraction 
Rate (SMER) value of 2.60 kg/ kWh compared to other methods of drying. It was found 
that the products dried with minimum drying time in HPD compared to greenhouse 
drying but still in the economic point of view greenhouse drying has low cost.",

AB  - The efficient utilization of waste from food industry is possible after thermal treatment of the material. This treatment should be economically feasible and compromise the energy efficient drying process. The main goal of this investigation is to determine drying characteristics of nectarine pomace as a waste from food industry. The measurements were performed in an experimental dryer by combined conductive-convective drying method with disk-shaped samples of 5, 7, and 10 mm thickness and 100 mm in diameter at the air temperatures of 30, 40, 50, 60, and 70 degrees C, hot plate temperatures of 50, 60, and 70 degrees C and air velocity of 1.5 m/s. The drying curves were compared to a few semi-theoretical mathematical models. The Logarithmic model showed the best correlation. On the basis of experiments, it is determined that the drying process takes place in a falling rate period and it is accepted that the main mechanism of moisture removal is diffusion. The effective coefficient of diffusion was determined using experimental results by calculating the slope of the drying curves. Drying time and equilibrium moisture are determined for each experiment. Analysis of drying curves showed that the conductive-enhanced drying method reduces drying times and increases the diffusivity coefficient. The character of drying rate curves for conductive-enhanced drying was analysed and compared with pure convective drying of nectarine pomace.

AB  - The aim of this research is to study the drying kinetics of vacuum-dried and freeze-dried bee honey produced from two different varieties: Sunflower honey (Helianthus Annuus L.) and Acacia honey (Robinia pseudo acacia L.). Vacuum drying treatments were carried out with the honey samples' initial temperatures of +25 degrees C, -20 degrees C, and -40 degrees C. Water content, total soluble solids, as well as the water activity of fresh and dried honey samples were determined. Freeze-drying of bee honey with initial sample temperature of -40 degrees C has resulted in shorter drying time (7-9 hours), moisture content (10%-12%), water activity (0.405-0.427 aW) and effective moisture diffusivity coefficient (8.26.10-7-9.51.0-7 m(2)/s). The high-performance liquid chromatography method was used when analyzing the impact that drying pre-treatments had on honey quality. The application of pre-treatments has led to an increase in hydroxy-methyl-furfural by 39-71%, and a decrease in diastase activity by 17-36%, all compared to fresh honey samples. The solutions of Verma model proved to be the best fit with the experimental results.

AB  - This paper presents a case study of a barley field experiment that was periodically scouted using a drone spectral camera. The camera has 4 bands so barley was scouted using 4 wavelengths of light - Green, Red, Red Edge and Nir Infra Red (NIR). Based on these wavelengths it is possible to calculate different vegetation indexes known in science and practice. In this paper, 15 such indices were used. The research work concerned the observation of correlation between individual wavelengths and corresponding vegetation indexes. This paper seeks to emphasize the importance of particular wavelengths and spectral areas in crop scouting

AB  - The aim of this research was to study the impact of application technique and rate of liquid starter fertilizer applied with a novel device on the production of corn. Starter fertilizer was applied in the root system range of freshly germinated plants in the 'belt' and 'point' forms at different quantities (35, 50, 70, and 100 L ha(-1)), which led to intensive plant growth in the initial stages of development. This adapted system was used for sowing and for application of the liquid starter fertilizer at the same time. The field trial was set up at two sites (two different land types), in the conditions of the natural water regime of the soil during the three vegetation seasons in the period 2016-2018. For this purpose, a prototype of the electronic device EUKU-01 was designed. The starter fertilizer was applied at 5 cm laterally from the row where the sowing was performed and 5 cm below the depth at which the corn seeds were sown. Data were statistically analyzed by two-factor analysis of variance, where the influence of mineral fertilizer treatment and the influence of liquid starter fertilizer treatment were observed as factors. The results showed that the optimal choice of the technique of liquid starter fertilizer application can result in fertilizer savings by 30% without reducing yield.

The cascade heat pump was designed to use ambient air as heat source with temperature t(amb )= -20 degrees C and for heating water in the high-temperature heating system up to 70 degrees C. The projected heating capacity of the cascade heat pump was 100 kW. The coefficient of performance (COP) of the cascade heat pump system due to use of different working mediums combinations in cycles of the cascade heat pump was investigated. For the best combination of working fluids (mediums) sub-cooling super-heating pressure loss in compressor's suction line, as well as exergy efficiency of the heat pump were analysed as a function of the temperature of the cascade heat exchanger.
