Embodiment Construction

[0029] The rapid determination method of the resistant starch content of the wheat grain comprises the following steps:

[0030] (1) Select a certain amount of grains of different wheat materials in the germplasm resource bank. Each material is clean wheat grains after manual removal of impurities, and grind the wheat grains into fine powder with a cyclone mill equipped with a 0.8 mm sieve plate , and then put the obtained wheat flour into a sealed bag, put it into a drying oven in an open shape and dry it at 40°C for 8 hours, take it out, cool it naturally and seal it for later use; in this way, whole wheat flour materials of different materials can be prepared .

[0031] (2) Using the K-RSTAR resistant starch kit produced by the Irish company, the resistant starch content of each whole wheat flour material was measured multiple times according to the AOAC method 2002.02 resistant starch determination principle, and then the average value of the multiple measurement results w...

Abstract

The invention relates to a wheat grain resistant starch content rapid measurement method and belongs to the technical field of wheat grain resistant starch content prediction. The wheat grain resistant starch content rapid measurement method achieves a purpose of rapidly measuring the wheat grain resistant starch content by establishing a medium-infrared spectroscopy model related to the wheat grain resistant starch content. Compared with a chemical measurement method, the method is fast, efficient and environmentally friendly, and meets the needs of people.

Description

technical field [0001] The invention relates to a rapid determination method for resistant starch content of wheat grains, belonging to the technical field of prediction of wheat resistant starch content. Background technique [0002] Most starches are easily digested, while resistant starch is a linear molecule of α1,4 D-glucan, mainly derived from degraded amylose, which is not digested as quickly as ordinary starch. The currently generally accepted definition of resistant starch is "starch and its degradation products that are not absorbed in the small intestine of healthy individuals". Resistant starch has attracted widespread attention because of its biological functions such as reducing insulin response, relieving diabetes, controlling body weight, and promoting the absorption of mineral ions, and has broad application prospects in human health. [0003] Wheat is one of the most important food crops in the world. It is of great significance to study the content and fu...
