Pretreatment of buckwheat globulin by ultra-high pressure: Effects on enzymatic hydrolysis and final hydrolysate lipid metabolism regulation capacities.

The purpose of this study was to evaluate the effects of ultra-high pressure (UHP) pretreatment on the buckwheat globulin and the regulation of lipid metabolism disorder by its enzymatic hydrolysates (BGH). Buckwheat globulin hydrolysates pretreated by ultra-high pressure (UBGH) can significantly reduce the levels of total triglyceride (TG) and total cholesterol (TC) in model cells (MOD), significantly inhibit lipid accumulation and steatosis. In addition, UBGH can significantly reduce the content of malondialdehyde (MDA), increase the activity of total superoxide dismutase (T-SOD) and total antioxidant capacity (T-AOC), thus reducing the vicious cycle of lipid metabolism disorder caused by oxidative stress. RT-PCR and western blotting analysis showed that after UBGH intervention, compared with the MOD group, the mRNA expression levels of liver lipid and cholesterol metabolism related genes were significantly changed. UBGH significantly increased PPARα and LXRα and decreased SREBP2 mRNA expression. Therefore, UHP technology could enhance the regulatory effect of BGH on lipid metabolism disorder.
