Three types of monofloral honey (rapeseed honey, buckwheat and lavender) from the Republic of Moldova were analyzed. The results of the palynological analysis showed that the samples had a dominant type of pollen (at least 45%). In the case of lavender honey, the pollen of the plant Lavandula angustifolia is present in an average value of 74.83 ± 0.3; in rapeseed honey - Brassica napus and for buckwheat honey -Fagopyrum esculentum in average values as follows: 56.07 ± 0.3 and 68.08 ± 0.2% respectively. The study of the content of biologically active substances showed that buckwheat honey is the richest in polyphenols (9.00 ± 0.11 mg gallic acid / kg) and carotenoids (4.24 ± 0.57 mg βcarotE / kg), and maximum content of flavonoids is in rapeseed honey (4.52 ± 0.28 mg catechin / kg). Thus, the obtained results confirm that the honey from the Republic of Moldova falls within the limits recommended by the international regulation assuming adequate working conditions, handling, collection and storage of honey by beekeepers from the Republic of Moldova.

Abstract At present, the preservation of the consumer properties of berry products is an urgent problem. Use of fresh garden strawberries is limited by a short storage period and seasonality. Under optimal storage conditions in a normal atmosphere, the average shelf life of strawberries is from 2 to 9 days depending on the variety. To meet the needs of the population in garden strawberries and meet the physiological needs in a unique complex of biologically active substances, strawberries are subjected to different processing methods. Drying being a type of fruit and berry products processing has the following advantages: a significant increase in the shelf life of products, a decrease in the mass and storage volumes of dried berries, preservation of minerals, carbohydrates, dietary fiber, antioxidants, bioflavonoids and many biologically active compounds in berries. Modern drying technologies allow preserving the content of essential vitamins to its full extent. Comparison of two technologies for drying garden strawberries has established that vitamins and other biologically active substances are well preserved in berries. Berries dried by convective vacuum-impulse method (CVI) are recommended to be used for food enrichment.

При производстве качественной пищевой продукции особое внимание необходимо уделять ее упаковыванию и хранению. Витаминно-минеральные концентраты, используемые для приготовления пищевых продуктов и получения качественной безопасной продукции животноводства, содержат комплекс лабильных биологически активных веществ, для сохранности которых необходимо минимизировать окислительные процессы. Это обусловливает повышенные требования к упаковке таких продуктов. С целью выбора упаковочного материала и способа упаковки витаминно-минерального концентрата проведен тематический обзор публикаций отечественных и зарубежных ученых. Рассмотрены тенденции в области применения упаковочных материалов, указаны преимущества и недостатки биополимеров. На основе проведенного анализа установлено, что для упаковывания витаминно-минерального концентрата целесообразно в качестве материала упаковки использовать полимерные пленки, обладающие высокой свето- и газонепроницаемостью, позволяющей снизить скорость протекания окислительных процессов и, следовательно, сократить потери содержащихся в продукте лабильных биологически активных веществ. В качестве способа упаковки можно рекомендовать применять вакуумирование, обеспечивающее отсутствие кислорода воздуха в упаковке. When producing high-quality food products, special attention should be paid to their packaging and storage. Vitamin and mineral concentrates used for food preparation and production of high-quality safe livestock products contain a complex of labile biologically active substances, for the safety of which it is necessary to minimize oxidative processes. This leads to increased requirements for the packaging of such products. In order to select the material and method of packaging of vitamin and mineral concentrates, a thematic review of publications of domestic and foreign scientists was conducted. Trends in the use of packaging materials are considered, advantages and disadvantages of biopolymers are indicated. It was found that for packaging vitamin and mineral concentrate, polymer pellicle with high light and gas tightness, which allows reducing the rate of oxidative processes and, consequently, reducing the loss of labile biologically active substances contained in the product, should be used as a packaging material. Vacuuming, which ensures the absence of oxygen in the air in the package, can be recommended as a method of packaging.

The object of the study was the fruits of milk thistle [Silybum marianum (L) Gaertn.] and fatty oil obtained from them by hexane extraction in the Soxlet apparatus. The aim of the study was to study the influence of natural and climatic conditions on the accumulation of fatty oil and other biologically active substances in the fruits of milk thistle growing on the territory of the Republic of Dagestan. It was found that the content of fatty oil and proteins in the fruits of milk thistle increases with a decrease in air temperature, an increase in the amount of precipitation and soil moisture at the place of growth; the content of carbohydrates and flavolignans in the studied samples of milk thistle fruits is inversely dependent on the content of fatty oil. It was revealed that with an increase in the amount of precipitation and a decrease in the amount of active temperatures during the change of the natural and climatic zone from the foothill Kaitagsky to the high-mountain Kulinsky district, the total content of unsaturated fatty acids, primarily linoleic acid, in milk thistle oil samples decreases. The method of differential scanning calorimetry has been used to study the thermophysical properties of the fatty oil of milk thistle growing in the Kulinsky, Levashinsky and Kaitagsky districts of Dagestan. The results of the thermal analysis are in good agreement with the conclusions obtained from the results of chemical and chromatographic analysis, differential scanning calorimetry allows us to identify trends in the change in the fatty acid and triglyceride composition of milk thistle fatty oil, depending on the natural and climatic conditions of the growth of milk thistle.
