A food ingredient containing phytoecdysteroids and polyphenols from quinoa grain: technology and physiological and biochemical evaluation in vivo

An effective technological approach to produce adaptogenic microingredients is concentrate plant biologically active substances via sorption on various matrices. The aim was develop and evaluate in vivo the phytoecdysteroids flavonoids extracted from quinoa grain sorbed coagulated chicken egg protein. consecutive extraction of conducted followed by experiment performed during 37 days using Wistar male rats. developed added into diet experimental animals dose 0.59±0.02 g/100 g diet. As a stress model we used daily 40-min immobilization exhaustive 3-hour at end experiment. Urinary catecholamines content determined, blood corticosterone, malon dialdehyde, glutathione reductase superoxide dismutase determined. Phytoecdysteroids were concentrated 20 80 times respectively compared initial raw materials. consumption neutralized negative effect anxiety level significant decrease urinary excretion adrenaline noradrenaline shows pronounced concentrate, whereas act as prostressors activating body antioxidant protection system, what substantiated significantly increased animals.
