- Abstract
This article explored the effects of different intestinal conditions and particle size on in vitro digestion of processed Carya cathayensis Sarg.(CCS), matrix degradation rate (MDI), digestibility of fat and protein, total phenols and antioxidant activity of processed CCS were analyzed under different bile salt concentration, intestinal pH values and pancreatic lipase concentrations according to the intestinal conditions of healthy adults and people with exocrine pancreatic insufficiency (EPI). The results showed particle size had the most significant effect on processed CCS in vitro digestion, and the MDI, antioxidant activity and digestibility of fat and protein of small particle processed CCS were higher than those of large particle processed CCS. The pH and bile salt were associated with fat digestion and antioxidant activity. When pH value was 7 and bile salt concentration was 10 mmol·L-1, the fat digestion effect was better. The digestibility of fat and protein would be high when the concentration of pancreatic lipase was high. Therefore, people with EPI can take in the appropriate amount of prebiotics and trypsin preparation to improve the nutrient digestion and utilization rate of CCS products.
