Aqua-culture improved buckwheat sprouts with more abundant precious nutrients and hypolipidemic activity

Abstract

Nutritional values of buckwheat reach maximum on day 8 sprouting by solid-phase cultivation (BSSC). The precious nutrients surveyed included linolenic acid, total polyphenolics, rutin, quercetin, l-ascorbic acid and gamma-aminobutyric acid. To investigate whether a change of cultivation method could improve the nutritional status, we performed aquaculture. By performing chemical, biochemical and animal experiments, we found that maximization of nutrient levels in aquacultured buckwheat sprouts (BSAQ) occurred 2 days earlier than those from BSSC. Simultaneously, their bioactivities were much enhanced, being superior to BSSC regarding antioxidative, free radical scavenging (FRS), anti-low-density lipoprotein lipoperoxidative capabilities and hypolipidemic bioactivity with respect to serum total cholesterol and triglyceride levels in Syrian hamsters. In addition, serum low-density lipoprotein-cholesterol (LDL-C) and high-density lipoprotein-cholesterol (HDL-C) levels and the ratios LDL-C/HDL-C and total cholesterol/HDL-C were all more efficiently suppressed by BSAQ diets. In conclusion, aquaculture is more efficient than the solid-phase cultivation with regard to acceleration and maximization of precious nutrient levels in buckwheat sprouts.

Effects of Yeast Polysaccharide on Growth and Flavonoid Accumulation in Fagopyrum tataricum Sprout Cultures

“…In particular, the contents of the major functional phytochemicals ( i.e. , rutin, quercetin and γ-aminobutyric acid), which have a variety of interesting pharmacological effects, are also effectively increased [ 11 , 12 , 13 , 14 ].…”

Hypolipidemic activity of common (Fagopyrum esculentum Moench) and tartary (Fagopyrum tataricum Gaertn.) buckwheat

“…Peng et al reported that aquacultured buckwheat sprouts were much enhanced, being superior to solid‐phase cultivation regarding antioxidative, free radical scavenging, anti‐LDL lipoperoxidative capabilities and hypolipidemic bioactivity with respect to serum TC and triglyceride levels in Syrian hamsters . In addition, serum LDL‐C and HDL‐C levels and ratios of LDL‐C/HDL‐C and TC/HDL‐C were all more efficiently suppressed by aquacultured buckwheat sprouts diets.…”

Sprouts as Source of Valuable Nutritients

“…Stwierdzono maksymalną zawartość minerałów w kiełkach przy stężeniu badanych soli wynoszącym 0,1 % (m/v) w roztworze hydroponicznym [45]. Zastosowanie akwakultury w produkcji kiełków gryki znacznie skróciło proces, a także zwiększyło aktywność przeciwutleniającą i hipolipidemiczną, a także zdolność wygaszania rodników [36]. Kiełkowanie brązo-wego ryżu w obecności chlorku chromu prowadziło do wzbogacenia produktu w ten pierwiastek.…”
