Summary The paper presents the results of three-year research on technological properties of fruits and quality of compotes made of four Novi Sad (NS) apricot cultivars (NS-4, NS-6, Novosadska rodna and Novosadska kasnocvetna) and five selections (SK-1, SK-3, SK-5, SK 13a and SK 16a). Apricots for this research on technological properties and making compotes were harvested in a collection of apricot genotypes of the Department of Fruit Growing, Viticulture, Horticulture and Landscape Architecture of the Faculty of Agriculture in Novi Sad, in the site “Rimski šančevi” (45º 20̓ 00ˮN,19°51̓ 100ˮE). Technological properties were investigated at the Faculty of Technology in Novi Sad and a laboratory of “Soja-Protein, AD Bečej” company. The investigated technological properties were: the amount of dry matter, total and reducing sugars, total acids, sucrose, total pectins, cellulose and mineral matter. These properties of NS cultivars and selections were compared to Hungarian Best (as a standard). The fruits of the NS cultivars and selections expressed better technological properties than Hungarian Best. The properties such as colour, aroma, taste, condition and consistency were sensory evaluated, with a method of giving points, used at the Novi Sad International Agricultural Fair. The compotes of the NS cultivars and selections were given more points than the compote made of standard. As for the total organoleptic properties, the compotes of selections SK-3, SK 13a and SK-5 stand out.

Chrysanthemums harvested as buds of 50-60 mm in diameter and held in the solutions of sucrose and 8-HQS had inflorescences of quality equal to those opened on the plant and better than flowers placed in water. Exogenous sucrose prolonged vase-life of cv. 'Bronze Bornholm' but did not affect cv. 'Crimson Robe'. No difference was observed in the quality of flowers placed in different sucrose concentrations. All the solutions which improved keeping qualities of cut chrysanthemums caused considerable increase in the flower fresh and dry matter. Also an increase in reducing sugars was found in flowers of both cultivars he1d in the solutions of sucrose and 8-HQS.

Term Storage

Experimental studies have shown that with an increased level of mineral nutrition (N120P180K240) all varieties increased the yield (by 1.7–4.1 tons/ha, or by 10–25%), while the most productive varieties being Bryansky Nadezhny, Bryanskaya Novinka, Slava Bryanshchiny (21.9–22.9 tons/ha). In terms of dry substances content almost all varieties met the requirements of processing, which called for for a dry substance level in tubers of at least 20–24%. With an increase in the dose of fertilizers the amount of starch and dry matter in tubers decreased. On an average background, the starch content compared to the control decreased by 0.7–1.1%, dry substances — by 0.7– 1.2%, on an increased background respectively — by 1.2–1.7%, dry substances — by 1.4–2.7%. The taste of potatoes on an increased background of fertilizers worsened regardless of variety. In terms of darkening of the flesh, raw cleaned tubers of all varieties are not suitable for long-term storage (for example, for 24 hours), while boiled tubers of all varieties did not reduce the quality. Growing potatoes on an increased background of mineral nutrition increased the darkening of raw tubers of the studied varieties compared to control. In the studied varieties the content of reducing sugars in many cases exceeded the amount allowed for the manufacture of crispy potatoes, and therefore its quality was reduced, mainly due to the color of the slices. Almost all varieties gave puree of good quality. An increase in the background of fertilizers slightly worsened the consistency of puree, which reduced the overall estimate.

Abstract This study aimed to evaluate the chemical and fermentation quality of silage from two sorghum hybrids in different layers of the silo feed-out face, as well as the interference of the aerobic exposure time of structured and/or unstructured silo face (after feed-out). The AG-2005E hybrid silage presented higher crude protein content and higher pH compared to hybrid AG-60298 (6.33% and 4.0 versus 6.06% and 3.8, respectively). Silages from stratum 0 to 20cm had the lowest dry matter content and the highest crude protein content (38% and 6.35%, respectively). The pH did not differ between layers, and the NH3 content was higher in the stratum 60 to 80cm (4.5%). During 72 hours of aerobic exposure, the unstructured silage presented a higher increase in temperature than the silage from the structured face, but this period was not enough to result in differences in dry matter, mineral matter, NH3, and pH. The chemical and fermentation quality of the silage was directly influenced by hybrid and silo stratum. After aerobic exposure, silage from the structured face seems to suffer less interference compared to the silo feed-out face.

The objective of this work was to access processing quality of potato clones (Solanum tuberosum) Asterix, SMINIA793101-3, and Missaukee cultivated during spring and autumn growing seasons and stored at 4, 8, 12, or 25ºC. Clones grown in spring had shorter dormancy than clones grown in autumn. Potato tubers grown in spring and autumn and stored at 4ºC, as well as tubers grown in autumn and stored at 8ºC had no sprouting for six months. Among clones grown in autumn, the longest dormancy period during storage at 12ºC was observed in the clone SMINIA793101-3, and at 25ºC was in the clone Asterix. In potato tubers grown in spring, the longest dormancy period during storage at 8ºC was observed in the clones SMINIA793101-3 and Missaukee, at 12ºC was in the clone SMINIA793101-3, and at 25ºC was in the clones Asterix and Missaukee. Potato tubers grown in spring had higher dry matter, starch content, and respiration rates, and lower reducing sugar, and total polyphenol content. The only exception was the Missaukee that had similar dry matter content in both growing seasons. In general, storage at 4ºC and 8ºC were more effective in reducing respiration rates and maintaining higher dry mater content of potato tubers. Chip darkening, reducing sugars, and total polyphenol content increased during storage of potato tubers. Darker chip color, higher reducing sugars and polyphenol content were obtained during storage at temperatures of 4ºC and 8ºC. These results suggest that the best storage temperature depends on genotype, tuber physiological age, and growing conditions.

Aims: The objective was to determine the influence of the onion harvest time "Baia Periforme" on post-harvest quality of the bulbs during storage. Study Design: The experiment was conducted in a randomized block design with three treatments, six replicates with two bulbs each. Place and Duration of Study: Departamento de Fitotecnia, Universidade Federal de Viçosa, between June 2017 and July 2018. Methodology: Seedlings, 20 days old, were transplanted into 20 cm spacing between rows and 10 cm between plants. The bulbs were harvested 120 days after transplanting with manual tipping of the pseudo-stem (T1), with 50 (T2) or 75% (T3) of the bulbs popped. The soluble sugars (SS), non-reducing sugars (NRS), reducing sugars (RS), total soluble solids (TSS), titratable acidity of phenolic compounds and alinase activity was determined every 30 days for 90 days. Results: The content of SS, TSS, phenolic compounds and alinase activity increased in the onions of T2, resulting in more sweet and pungent bulbs due to the higher content of acidity and phenolic compounds. Conclusion: The post-harvest quality of onion bulbs "Baia Periforme" was maintained when they were harvested with 50% of bulbs popped.

Innovative active packaging has the potential to maintain the food quality and preserve the food safety for extended period. The aim of this study was to discover the effect of active films based on commercially available polylactic acid blend (PLAb) and natural active components on the shelf life and organoleptic properties of chicken fillets and to find out; to what extent they can be used as replacement to the traditional packaging materials. In this study, commercially available PLAb was compounded with citral and cinnamon oil. Active films with 300 µm thickness were then produced on a blown film extruder. The PLAb-based films were thermoformed into trays. Fresh chicken breast fillets were packed under two different gas compositions, modified atmosphere packaging of 60% CO2/40% N2, and 75% O2/25% CO2 and stored at 4 ℃. The effect of active packaging materials and gas compositions on the drip loss, dry matter content, organoleptic properties, and microbial quality of the chicken fillets were studied over a storage time of 24 days. The presence of active components in the compounded films was confirmed with FTIR, in addition the release of active components in the headspace of the packaging was established with GC/MS. Additionally, gas barrier properties of the packages were studied. No negative impact on the drip loss and dry matter content was observed. The results show that PLAb-based active packaging can maintain the quality of the chicken fillets and have the potential to replace the traditional packaging materials, such as APET/PE trays.

The influence of three factors: sowing date (l0th April, 25th April, 10th May), sowing rate (4, 6, and 8 kg × ha<sup>-1</sup>), and row spacing (20, 25, and 30 cm), on the quantity and quality of yield of Welsh onion 'Sprint' was examined in the experiment. The highest total and marketable yield were obtained when seeds were sown on 25th April. An increase in sowing rates resulted in a significant increase of yield. The highest total and marketable yield were obtained at a sowing rate of 8 kg × ha<sup>-1</sup>. However, significantly greater total and marketable yield were obtained at a row distance of 20 cm. Dry matter content in Welsh onion yield depended significantly on the sowing date and the part of the plant. Plants obtained from seeds sown on 10th May contained the highest content of dry matter. Significantly more dry matter was in the pseudostems than in the leaves of Welsh onion. However, higher L-ascorbic acid content was estimated in the leaves. Welsh onion obtained from the earliest sowing date (10th April) contained significantly the most reducing sugars. Welsh onion obtained from seeds sown on 25th April was characterized by the highest content of pyruvic acid.

Abstract Quality of the tuber is an important factor determining utilization and economic values of the potato (Solanum tuberosum L.) plant. The acceptance of potato variety for industrial processing is determined by the dry matter, starch and reduced sugar contents as well as market acceptance of the products. These characteristics are influenced by the potato variety and cultivation season. This research aimed to evaluate the tuber and organoleptic properties of chips from four potato varieties grown during off-season, in Sajang Village of Sembalun District (at ca. 900 m above mean sea level). A plantation was undertaken at the end of rainy season in 2021, and comprised of four potato varieties, designated as McRusset, Ranger Russet, Chitra and Atlantic. After harvesting and stored at ambient temperature for 2 weeks, raw tubers were characterized for the dry matter, starch, and reduced sugar contents. The tubers were fried as french fries and chips, and sensory analysis were undertaken for likeliness in color, flavour, crispness and overall appearance. The different in properties of these four varieties and its industrial utilization is be presented and discussed in this paper.

ABSTRACT Sweet potato branches have potential use in animal feeding, even fresh or ensiled, and some additives may enhance their quality. This study aimed at assessing silage quality of sweet potato branches using different additives. We ensiled sweet potato branches without additive (control) and with the addition of 10% disintegrated corn with straw and corncob (DCSC), 10% sugarcane bagasse from alembic, 10% citrus pulp, and 10% coffee husk. Three samples of each plot were obtained after drying for measurements of dry matter, crude protein, neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, hemicellulose, lignin, mineral matter, starch, soluble sugars, pH, lactic acid bacteria population, gas, and effluent losses. Silage with DCSC, citrus pulp, and coffee rusk reached the highest dry matter contents. Moreover, citrus pulp silage had a high content of NDF. In contrast, DCSC silage showed the lowest content of ADF. Lignin was low in silage with DCSC, citrus pulp, and control (without additive). Suitable amounts of starch, crude protein, and lactic acid bacteria population were found in all treatments. Silage with DCSC achieved the best results for the assessed variables. Therefore, DCSC is the most suitable additive to improve silage quality of sweet potato branches.
