Embodiment 1

[0031] The present embodiment provides a kind of preparation method of low protein rice, comprises the following steps:

[0032] Mix 1.0Kg of rice with 5.0Kg of water and heat while stirring until the water temperature rises to 45°C. Then add the composite biological package (0.2g prolamin, 0.4g gluten hydrolase, 0.2g aroma yeast, 0.15g brewer's yeast and 0.1g tryptophan functionalized graphene quantum dot-silver nano) and keep warm at 45°C After 10 hours, filter, wash, and dry in cold air at room temperature to obtain low-protein rice.

[0033] The protein content in rice was determined by Kjeldahl method, and the protein removal rate was 82%.

Embodiment 2

[0035] The present embodiment provides a kind of preparation method of low protein rice, comprises the following steps:

[0036]Mix 1.0Kg of rice with 10Kg of water and heat while stirring until the water temperature rises to 55°C. Then add the composite biological package (0.2g globulin hydrolase, 1.2g gluten hydrolase, 0.4g baker's yeast, 0.1g brewer's yeast and 0.15g tryptophan functionalized graphene quantum dots-silver nano) and keep warm at 55°C After 24 hours, filter, wash, and dry in cold air at room temperature to obtain low-protein rice.

[0037] The protein content in rice was determined by Kjeldahl method, and the protein removal rate was 93%.

Embodiment 3

[0039] The present embodiment provides a kind of preparation method of low protein rice, comprises the following steps:

[0040] Mix 1.0Kg of rice with 1.0Kg of water, and heat while stirring until the water temperature rises to 30°C. Then add the composite biological package (0.9g prolamin, 0.1g gluten hydrolase, 0.4g lactic acid yeast, 0.1g baker's yeast and 0.2g tryptophan functionalized graphene quantum dot-silver nano) and 2g citric acid (with Adjust the pH of the reaction system), keep warm at 30° C. for 6 hours, filter, wash, and dry in cold air at room temperature to obtain low-protein rice.

[0041] The protein content in rice was determined by Kjeldahl method, and the protein removal rate was 72%.

[0042] From the results of Examples 1-3, it can be seen that the rice is processed by the composite biological bag of the present invention, and the protein removal rate of the obtained low-protein rice can exceed 70%, and the removal rate of the protein by the composite...

Abstract

The invention discloses a composite biological bag for producing low-protein rice. The composite biological bag comprises a bag body and functional components located in the bag body. The functional component is composed of composite proteolytic enzyme, composite yeast powder and an antibacterial carbon material, wherein the composite proteolytic enzyme is embedded by an enzyme embedding agent; and in the biological bag, the contents of the compound proteolytic enzyme, the compound yeast powder and the antibacterial carbon material are respectively 40-90wt%, 5-70wt% and 1-10wt%. The invention also discloses a method for preparing low-protein rice by adopting the composite biological bag. According to the composite biological bag for producing the low-protein rice, the low-protein rice can be rapidly and conveniently produced, and the obtained rice is good in taste and low in protein content.

Description

technical field [0001] The invention relates to the technical field of low-protein rice preparation, in particular to a compound biological bag for producing low-protein rice and a preparation method of low-protein rice. Background technique [0002] Epidemiological studies have shown that my country is a country with a high incidence of chronic diseases, and the incidence of chronic kidney disease in adults is 10.8%. Clinical studies have shown that patients with chronic kidney disease have obstacles in protein metabolism and need to strictly limit protein intake (daily protein intake is less than 0.6g / kg). Excessive intake of protein will increase the burden on the kidneys, accelerate the decline of kidney function, and eventually lead to uremia. my country is a country where rice is the staple food, with an annual output of 200 million tons of rice, about 120 million tons of rice and its products for direct food consumption every year, and 40% of the daily per capita ene...
