Abstract

The invention discloses a method for rapidly determining high dietary fiber rice. The method comprises the following steps: (1) taking polished rice grains and cooking; (2) sequentially removing fat, protein and starch in the cooked rice grains by organic solvent extraction, protease hydrolysis and amylase hydrolysis to obtain residue; (3) by observing the form of the residue with the naked eyes, determining that the residue which can retain the intact grain form is high dietary fiber rice, and the residue which becomes white loose floccules without a grain structure is low dietary fiber rice, wherein the dietary fiber content of the high dietary fiber rice is more than or equal to 5 percent. The cooked polished rice grains are taken as a study object, the fat, the protein and the starch in the rice grains are removed by a relatively mild treatment method, and the content of the dietary fiber in the rice is determined by the appearance form of the rice grains; the method not only is simple and efficient, but also the results are accurate.

Description

technical field

[0001] The invention relates to the field of nutritional evaluation of functional staple foods, in particular to a rapid determination method for rice with high dietary fiber. Background technique

[0002] Dietary fiber refers to the general term of edible plant components or homologous carbohydrates that cannot be digested and absorbed in the small intestine, but can be completely fermented and degraded or partially degraded in the large intestine. It is divided into two categories: insoluble and water-soluble fibers . Dietary fiber contains low energy, which can control the cholesterol and blood sugar in the blood at an ideal level, and has many benefits to the human body. If the dietary fiber intake of the human body is insufficient, the incidence of diseases such as constipation, colon cancer, appendicitis, diabetes, obesity, coronary heart disease, and gallstones will increase. Today, as the diet is becoming more and more refined, the intake of dietary...
