Embodiment 1

[0014] Take 50 kg of broken rice and process it according to the following steps:

[0015] (1) Remove impurities and soak the broken rice: Use a classifier to remove the light bran husk and heavy gravel in the broken rice, and then soak the broken rice in deionized water for 5-8 hours; The broken rice is made into rice milk, and the rice milk is homogenized until the particle size is not greater than 2 microns;

[0016] (2) High pressure treatment: Stir the rice milk milk obtained in step (1) evenly and put it into polypropylene bags in batches, and after vacuum sealing with a vacuum sealing machine, obtain a double-layer encapsulated starch-water suspension sample; Put the packaged starch-water suspension sample into the high-pressure container of the ultra-high pressure equipment for pressure treatment. The high-pressure equipment is boosted at a boosting speed of 10Mpa / s, and the temperature in the high-pressure chamber is kept at 30±2°C , after boosting the pressure to 60...

Abstract

The invention discloses a method for extracting digestion-promoting starch from broken rice by an ultrahigh pressure technology. The method is based on the principle that in an ultrahigh pressure extracting process, a pressure gradient can promote orderly rearrangement of molecular chains inside original starch granules as well as can cause expansion outside the granules without breakage, so that starch production is promoted; the method comprises the following steps: removing impurities from the broken rice, soaking the broken rice without the impurities, performing high-pressure treatment, performing recrystallization within a short time, performing centrifugation, collecting filter cakes, and performing air blast drying and crushing. The digestion-promoting starch extracted according to the method has the advantages of high nutritional value and safety, slow absorption, lasting energy release and the like.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of broken rice, in particular to a method for extracting digestion-promoting starch from broken rice by using high-pressure technology. Background technique [0002] In rice product processing enterprises, the existence of broken rice does not meet the quality requirements of rice products, and its commodity value is only 40% to 50% of the whole rice, which seriously affects the economic benefits of the enterprise. Moreover, for the raw material selected for the production of digestible starch, the digestible starch content of broken rice and whole rice is not much different. Therefore, the use of high-pressure technology to extract digested starch from broken rice reflects the comprehensive utilization of broken rice on the one hand and improves the economic benefits of enterprises; Digestive starches are also fully utilized. Contents of the invention [0003] The purpose of...
