Abstract:
One of the main modern trends in the food and processing industry is expanding the range of fortified food products using by-products. By-products from fruit and berry processing include berry pomace, which can be used as an ingredient to fortify food products. The purpose of this study was to investigate the content of biologically active substances in dried blackcurrant and sea buckthorn pomace and to assess their nutritional value. The study found that blackcurrant pomace contains the following in mg per 100 g: catechins – 2026.50; anthocyanins – 315.00; vitamins B1 (thiamine) – 2.2; B5 (pantothenic acid) – 5.9; B6 (pyridoxine) – 5.4; C (ascorbic acid) – 126.72. The content of biologically active substances in blackcurrant pomace allows it to be positioned as a source of catechins, anthocyanins, and vitamin C; despite the relatively low content of vitamins B1, B5, and B6, their amount is sufficient to replenish the daily requirement when consuming 100 g of pomace. It has been established that sea buckthorn extracts contain, in mg per 100 g: catechins – 1690.67; carotenoids – 16.63; vitamins B3 (nicotinamide) – 3.2; B5 – 1.9; B6 – 0.3; C – 16.72; retinol – 3.83 mkg; D2 (calciferol) – 5.61 mkg; E (α-tocopherol) – 27.52; K1 (phylloquinone) – 36.40 mkg. The composition of sea buckthorn extracts allows them to be positioned as a source of catechins, carotenoids, vitamins C, E and D2; the content of vitamins B3, B5, B6, K1 and retinol is not sufficient to replenish the daily requirement. The results of the study demonstrate the potential of using blackcurrant and sea buckthorn extracts to increase the nutritional and biological value of food products.
