Screening Of Functional Sugars That Stimulate GLP-1 Secretion And Preparation And GI Evaluation Of Protein Particle Bars

Due to the unreasonable dietary structure(excessive intake of fat and fine staple foods,and insufficient intake of dietary fiber),health problems such as obesity,diabetes,hypertension,and hyperlipidemia are becoming more and more serious,and the development of functional foods that meet the needs of different populations is important significance.In this study,GLP-1 was used as a main indicator to screen out functional sugars that stimulate GLP-1 secretion,and as a nutrient factor added to protein particle rod products,a functional high protein particle rod was developed.The main findings are as follows:(1)Cell evaluation test for 6 kinds of sugars such as trehalose,isomalt,sorbitol,xylitol,erythritol and L-arabinose,functional sugars that promote GLP-1 secretion in the small intestine were determined.It is trehalose,isomalt,sorbitol,erythritol.(2)Through sensory evaluation and texture analysis of 8 commercially available rod products,a method for evaluating rod products was established.The product formulation and process are determined by comparing the binder ratio,the binder to protein particle ratio,and the main process parameters as follows: On the basis of 4.8% inulin,1.2% stachyose and 1% trehalose,the optimum ratio of binder sorbitol: oligo-isomalt: maltitol is 3:1:5.The optimum MCT oil addition is 3%,the optimum ratio of binder to protein particles is 37%,the optimum binder temperature is 105?,and the optimum speed is 200 r/min.The product has a protein content of 37g/100 g.(3)The protein particle rod was stored at T65 ° C and RH 75% conditions,and the changes in peroxide value and water activity were measured to determine that the protein particle rod could be stored under these conditions for 35 days.According to the Arrhenius oven empirical formula,the shelf life of the protein pellets was predicted to be 560 days at room temperature(25?).(4)In vitro GI evaluation of protein granules by oral,stomach and intestinal simulated digestion showed that the GI value of the product was 60;the GI value of the human GI test protein granule was 67.88,and it was determined that the product belongs to the middle GI food.(GI ? 55 low GI food,55 <GI ? 70 medium GI food,GI > 70 high GI food).The product has less influence on blood sugar fluctuations and has a strong sense of satiety,and can be used as a nutritious meal replacement product for people who are losing weight.
