The study presents the effects of fertilisation on selected quality parameters of the dried material obtained from plants of lovage and coriander. During the crop production process, the plants were treated with two fertilisers containing substances potentially acting as elicitors. The dried material was obtained in course of a drying process carried out in optimum conditions and based on the CD-VMFD method which combines convective pre-drying (CD) at a low temperature (40 °C) with vacuum-microwave finish drying with the use of 240 W microwaves (VMFD). The quality of the dried material was evaluated through measurement of the total contents of polyphenols, total antioxidant potential (ABTS and DPPH method), and the profile of volatile compounds (headspace-solid phase microextractio-HS-SPME) as well as assessment of the colour. It was found that by applying first fertilisation (with organic components) it is possible to significantly increase the contents of both bioactive compounds and volatile substances responsible for the aroma. It was determined that the higher content of bioactive compounds was related to the composition of the first fertiliser, presumably the extract from common nettle. The study showed that the application of the first fertiliser contributed to enhanced quality parameters of the raw material obtained.

The climate changes in Murfatlar vineyard in recent years consist inthe increase ofmonthly average temperatures, recorded in both cold and warm seasons, accompanied by an irregular distribution of rainfall during the year, which significantly influences the growth of grapevine, the quality and production of grapes.Six representative cultivars were studied, three for white wines: Chardonnay, Columna and Muscat Ottonel and three for red wines: Fetească Neagră, Mamaia and Cabernet Sauvignon. In the last two years (2019-2020) warm winters and very dry summers have led to the onset of budburst, almost simultaneously for all the studied cultivars, followed by a very weak growth and development of shoots (2020) and an acceleration development of phenophases, mainly berween veraison and ripening. Water stress during the vegetative period, a hygroscopicity below 60% between July and August and low vegetative apparatus influenced the growth ofthe berries, resulting small grapes, and a very low must yield in 2020.Concerning the quality of grape production, the studied cultivars achieved more sugar concentrations in berries up to 35.8 g/L (in 2019) and 36.0 g/L (in 2020), higher than the values obtained in normal years. In the conditions of a pronounced dry climate manifested in the two years of study, the productions were below the normal level, especialy in 2020, achieving much diminished productions for all cultivars, except the Mamaia cultivar. The Mamaia cultivar had a positive reaction, registering an increase of production, that exceeded the multiannual value by 20% in 2020 andby 10% in 2019, the concentration of sugars in the must being above the average value obtained in normal years, exceeding by 3% and 9%, respectively, the multiannual average. Statistical calculations were done using SPSS Statistics 17.0, using mainly the Duncan test for a degree of significance of 5%.

In terms of geographical distribution and consumption, potatoes occupy one of the leading positions in the structure of food production in Ukraine. It is also used extensively as animal feed. The versatility of use in diff erent sectors of the economy with potatoes cannot be compared to any crop. Potato is of great importance as a raw material for the production of starch, sugar, molasses, alcohol, glucose and etc. A signifi cant reduction in the commodity production of food potatoe in farms is related to the solution a whole complex of important issues, in particular seed production, agro-technology of cultivation, application of highly eff ective pesticides, availability of agricultural machinery and material-technical support. The difficult ecological and energy situation in modern agriculture proves that it is possible to obtain high and stable yields of all crops only if there are varieties in production adapted to diff erent soil and climatic conditions. Variety is one of the important factors of yield stability and fi xed assets of agricultural production. A variety, as a genotype or a set of very close genotypes, exists in a specific environment and, moreover, interacts with it, encountering complex communication, intensity and time of manifestation, abiotic and biotic factors. At the same time, a connection is established between a variety and an environment that infl uences the formation and manifestation of morphological, economic and biological characters. The aim of the research was to study the growth, development and yield of early ripe potato varieties in the rightbank Forest-Steppe of Ukraine. The article presents the results of studies on the cultivation of early ripe varieties of potatoes. Namely, the germination and survival of potato plants was studied, which amounted to 89.5 and 87.3 % in the Skarbnytsa variety, 90.2 and 88.7 % in the Shchedryk variety, and 88.6 and 86.5 % in the Dnipryanka variety; the number of formed stems per plant is calculated, which is 3.3 in the Skarbnytsa variety, 3.6 in the Shchedryk variety and 2.7 in the Dniprianka variety. The dynamics of the mass increase and the fractional composition of potato tubers are shown. On average, during the research, the average weight of tubers from the bush was high for the Shchedryk variety and amounted to 616.2 g, somewhat less than those for the Skarbnytsa (484,5 g) and Dniprianka (397,8 g) varieties. It was established that the Shchedryk variety had the highest potato productivity in the experiment – 250.3 c/ha, in the Skarbnytsa and Dnipryanka varieties, the yield was 210.0 and 201.2 c/ha, respectively. Key words: potato, varieties, plant survival, tubers weight, productivity.

The aim of this study was to investigate the effects of raw material freshness on the quality of marinated fish. The raw material anchovy (Engraulis encrasicolus) was divided into two batches. One batch (A) was kept at ambient temperature (20°C) for 6 h and the other one was kept at 0°C for 72 h. Then, they were marinated by soaking into marination solution containing 3% acetic acid and 8% NaCl. Total volatile basic nitrogen (TVB-N), trimethylamine (TMA), thiobarbituric acid (TBA), para-anisidine (p-Av) values in both marinated samples increased significantly during storage at 4°C. Increases in quality parameters were higher in samples produced with raw anchovy kept at 20°C compared to samples kept at 0°C. Although the sensory scores of both samples decreased during storage, higher scores were obtained for samples kept at 0°C compared to samples kept at ambient temperature. According to the results of the study, it has been determined that the quality of the raw material significantly (p<0.01) affects the quality of marinated anchovy.Keywords: fish; quality; anchovy; marinade; raw material

Drying is known as the best method to preserve fruits, vegetables, and herbs, decreasing not only the raw material volume but also its weight. This results in cheaper transportation and increments the product shelf life, limiting the food waste. Drying involves the application of energy in order to vaporize and mobilize the moisture content within the porous products. During this process, the heat and mass transfer occurs simultaneously. The quality of dehydrated fruits, vegetables, and aromatic herbs is a key problem closely related to the development and optimization of novel drying techniques. This review reports the weaknesses of common drying methods applied for fruits, vegetables, and aromatic herbs and the possible options to improve the quality of dried products using different drying techniques or their combination. The quality parameters under study include color, bulk density, porosity, shrinkage, phytochemicals, antioxidant capacity, sugars, proteins, volatile compounds, and sensory attributes. In general, drying leads to reduction in all studied parameters. However, the behavior of each plant material is different. On the whole, the optimal drying technique is different for each of the materials studied and specific conditions must be recommended after a proper evaluation of the drying protocols. However, a novel or combined technique must assure a high quality of dried products. Furthermore, the term quality must englobe the energy efficiency and the environmental impact leading to production of sustainable dried products.
