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