Keywords: | crude-chalaza hydrolysate | hepatosteatosis | high-fat diet | insulin resistance | lipid homeostasis | Issue Date: | 1-Apr-2021 | Publisher: | ELSEVIER | Journal Volume: | 100 | Journal Issue: | 4 | Source: | Poultry Science | Abstract: | Approximately 400 metric tons of egg chalazae, a byproduct in the liquid-egg processing plant, are produced yearly but always regarded as a waste in Taiwan. Our team successfully developed a crude egg chalaza hydrolysate by protease-A digestion (CCH-A). Free branched-chain amino acids, 3-aminoisobutyric acid, and β-alanine, and anserine were assayed in the CCH-A used in this study. Besides, the in vitro bile-acid binding ability and inhibitory lipase activity of CCH-As were demonstrated. Then, high-fat diet feeding for 10 wk caused hyperlipidemia, insulin resistance, and hepatosteatosis in hamsters (P < 0.05). However, CCH-A co-treatment decreased serum/liver triglyceride levels and lipid accumulation in livers by increasing daily fecal lipid/bile-acid outputs, upregulating fatty-acid β oxidation, and downregulating fatty-acid biosynthesis in livers (P < 0.05). CCH-A co-treatment also amended insulin resistance, augmented hepatic antioxidant capacity, and decreased liver damages and inflammatory responses (P < 0.05). Taken together, our results do not only demonstrate the hepatoprotective effects of CCH-As against a chronic high-fat dietary habit, achieving effects similar to Simvastatin, but also decrease the environmental burden of handling chalazae in the liquid-egg industry. |
