Blood glucose generation index in-vitro test method

Abstract

The present invention discloses a blood glucose generation index in-vitro test method; according to the method, first, moisture, ash, fat and protein of a food sample are detected to obtain the amount of the food sample containing 1g of carbohydrates; by simulating of digestion of 1g of the carbohydrates of the 1g of carbohydrates by human body digestive system, the sample is taken for testing at different digestion time points, the starch consumption rate and the blood glucose level are calculated, and blood glucose generation index can be obtained by a theoretical calculation formula. According to the blood glucose generation index in-vitro test method, by in-vitro simulation of the in vitro digestion, the detection time is reduced, the detection requirement is reduced, and the problem of a significant amount of consumption of manpower and resources of in-vivo detection can be solved.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to an in vitro detection method of glycemic index. Background technique [0002] With the improvement of living standards, people pay more and more attention to health. However, due to changes in eating habits and a reduction in people's physical activity, obesity-related diseases are gradually increasing. The number of diabetics is also increasing year by year, so the development of food for diabetics has far-reaching significance. The detection method of glycemic index food has a guiding role in the development of such food. [0003] The food glycemic index refers to the percentage value of the blood sugar response level of a food containing 50g of carbohydrates and an equivalent amount of glucose within a certain period of time, which can reflect the speed and ability of food to raise blood sugar compared with glucose. The in vivo detection method of glycemic index ha...
