Studying the quality characteristics of the sweet-brier fruits growing in the Novosibirsk region

The purpose of research is to study the rose hips of the pomological variety Desertnyj, growing on the territory of the Novosibirsk Region, to determine its quality characteristics and the possibility of using it in the manufacture of food products. Research methods are standard. It has been established that the studied rose hips correspond in their technical characteristics (appearance, color, smell and taste, mass fraction of fruits with deviations in size, which have not reached removable maturity and color, overripe and with mechanical damage, impurities of plant origin) to the requirements of the current regulatory documentation. The size of the fruit according to the largest transverse diameter is not less than 1.4 cm, the average fruit weight is not less than 1.8 g. Rose hips contain at least 11.1 % sugars, 0.7 % proteins, 0.2 % fats, 1.9 % free organic acids, 0.8 % minerals, 3.3 % dietary fiber, 0.9 mg/100 g ascorbic acid, 0.8 mg/100 g dietary fiber and 0.04 mg/100 g β-carotene. Safety indicators (content of pesticides - hexachlorocyclohexane (α, β, γ-isomers), DDT and its metabolites; toxic elements - lead, arsenic, cadmium, mercury), including microbiological (content of molds and yeasts, mesophilic aerobic and facultative anaerobic microorganisms, coliform bacteria, as well as bacteria of the genus Salmonella) confirm the possibility of using rose hips without any restrictions. The studied rose hips have a nutrient composition that makes it possible to consider it as a promising raw material for expanding the range of new generation products.
