Rice bran oil, and preparation method of rice containing rice bran oil

Abstract

The invention provides rice bran oil and a preparation method of rice containing the rice bran oil. The preparation method comprises the following steps: removing rice husks from fresh rice, separating rice grains from rice bran, performing three-stage squeezing on the rice bran to obtain the rice bran oil, and mixing the rice bran oil with the rice grains to obtain the rice containing the rice bran oil. According to the method, the three-stage squeezed rice bran oil is produced through low-temperature physical squeezing, the nutritional value of the rice is not destroyed, the rice contains rich amino acids, proteins, vitamins, trace elements and the like, and the produced rice is directly added into carefully selected rice, so that the obtained rice has more comprehensive and more balanced nutrition, the glossiness and chewiness of the rice can be improved, and the prepared rice has better mouth feel.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a method for preparing rice bran oil and rice containing rice bran oil. Background technique [0002] The world's total rice production is 661.81 million tons (2008). my country is the largest country in rice production, with an annual output of 186.92 million tons of rice, and rice bran, a by-product of about 10%, is produced during rice processing. Rice bran is a mixture of the bran layer and germ separated when brown rice is whitened. About 10% of rice bran can be obtained by processing every ton of rice into polished rice. According to statistics, the annual output of rice bran in my country is about 13 million tons. This is a very huge renewable resource. However, rice bran is mainly used as feed to feed livestock and poultry in my country, and only about 10% of rice bran is used for deep processing, and resources are far from being fully utilized.

AI Technical Summary

Problems solved by technology

As far as my country's current situation is concerned, the annual production of rice bran is very large. Because rice bran is prone to rancidity and deterioration, and domestic production enterprises are scattered and the production scale is small, it is difficult to concentrate rice bran for deep processing and value-added. Only a small amount is used to prepare rice bran oil. , so that the rice bran oil can be comprehensively utilized, and the reutilization of its nutritional value can be improved, but a large amount of rice bran is only used as feed for pigs, cattle, sheep and other livestock, and its added value is very low. Therefore, it is necessary to use rice bran as a raw material Production of rice bran oil provides a viable solution

[0004] Rice bran oil contains an enzyme that can cause rapid corruption of rice bran oil. Therefore, its acid value will increase by several points every hour. Therefore, the traditional rice factory and oil factory are separated, and the rice bran oil for production and processing is used Chemical methods: high temperature, vacuum, acid and alkali, etc. control the increase of acid value in rice bran oil, so the obtained rice bran oil is not green and healthy

In addition, at present, rice bran needs to be removed during the process of obtaining rice. This process will cause the loss of some nutrients, mainly the nutrients in rice bran, thereby reducing the nutritional value of rice.
