THE CONTENT OF BIOLOGICALLY ACTIVE SUBSTANCES IN SEEDS AND SPROUTS OF BEANS OF THE PAPILIONOIDEAE SUBFAMILY

Background. The problems of population growth, high morbidity and simultaneous decrease in the area of fertile lands actualize the need to introduce functional food products into daily practice. The aim of the study was to compare the content of biologically active substances in seeds and seedlings of soybean Glycine max, mung bean Vigna radiata, bean Phaseolus vulgaris, alfalfa Medicago sativa. Materials and methods. The seedlings were obtained by the method of hydroponic culture in distilled water (7-10 days). Seeds and seedlings were examined in crushed air-dry form. The content of polyphenols and flavonoids was determined on a spectrophotometer, the content of ascorbic acid was determined by titration using the Tilemans method. Results. It has been shown that germination of all seeds leads to an increase in the content of polyphenols, flavonoids and ascorbic acid by 2-12 times. M. sativa and V. radiata sprouts turned out to be the most valuable sources of antioxidant compounds of the polyphenol group (21±5 and 20.0±2.9 mg/g, respectively). In terms of ascorbic acid content, the leaders were the sprouts of M. sativa and Ph. vulgaris (0.11±0,01 mg/g). Conclusion. M. sativa seeds, which are not recommended for human nutrition due to their high content of toxic canavanine, can complement functional food in the form of sprouts. EDN: DUKSQD
