JOFRKU

Abstract

The article presents the results of studies of the content of individual nutrients in quick-frozen strawberries of the O'Green, Green Ribbon and Miratorg brands in order to supplement the literature data and identify the most competitive products. For the first time, the results on the content of Al, B, Ba, Mo, Si, Sr, Ti, V and Zn in the variety mixtures of this berry have been obtained. The Green Ribbon products have a relatively high content of vitamin C, insoluble dietary fiber, flavonoids and mineral elements: P, K, Mn, Co, Si and Ti; O'Green fruits have high concentrations of Zn, Na, Mo, Ca, Mg, Fe, Cu, Sr, B and Ni, and Miratorg berries have levels of Mo, Cr, V, Ti and Se. Depending on the brand, one serving (250 g) of berries provides an adult with 68-182% of their daily requirement for vitamin C, 26-28% of dietary fiber, 5.1-10.2% of Ca, 7.9-12.7% of Mg, 10.0-15.3% of K, 9.2-14.8% of P, 0.3-1.0% of Na, 4.4-106.2% of Cr, 14.3-22.4% of Fe, 31.7-63.6% of Mn, 11.2-17.7% of Cu, 4.6-12.5% of Mo, 35.0-67.5% of Co, 11.8-17.3% of Si, up to 13.6% of Se, and by 18.3-36.7%, Zn - by 0.9-5.9%. Based on the totality of the obtained results, the competitive advantage was established for strawberries of the O'Green trademark.
