Example Embodiment

[0014] Embodiment 1: utilize dilute soybean milk (dilute soybean protein milk) to extract the technology of rice bran protein, and its steps are as follows:

[0015] (1) preparation of soybean milk: take 20 grams of soybeans as a raw material, add cold boiled water at a ratio of 1:5 and soak for 12 hours, remove the water, and make 640 mL of soybean milk (soy protein pulp).

[0016] (2) Preparation of rice bran extraction solvent: Divide 640 mL of soy milk into two equal parts, one is sample 1 (10 g soybean / 320 mL), used for quantitative analysis of soybean protein; the other is added with 640 mL of cold water to prepare dilute soybean protein pulp (10 g soybean / 960 mL) as a solvent for extracting rice bran protein and other natural product nutrients (sample 2) in rice bran.

[0017] (3) Preparation of Rice Bran Soy Protein Milk (Sample 2):

[0018] ① Use 40 grams of fresh rice bran as raw material, soak in cold boiled water at a ratio of 1:5 for 1 hour, remove the water, ad...

Abstract

The invention discloses a technique for extracting rice bran protein; the prior art used for extracting rice bran protein comprises the following methods: a base-dissolving and acid-precipitation method and an enzymatic method, and the defects are that the quality of the extracted protein is poor and the technique is complex, meanwhile, other natural product nutrient ingredients such as Gamma-oryzanol, etc. are eliminated as impurities; the technique of the invention adopts thin protein pulp as a solvent to extract the protein and other natural product nutrient ingredients with simple technique and low cost; the product (the rice bran protein pulp and the dried rice bran protein pulp product) contains vegetable protein and other natural product nutrient ingredients with rich nutrient ingredients, can be used for production of food, drinks and health products, thus improving the added value of the rice bran, and having important significance for the comprehensive application of the rice bran and environmental protection.

Description

Technical field: [0001] The invention relates to a process for extracting rice bran protein and other nutrients in rice bran by using dilute protein slurry. Thin protein syrups include thin soy protein syrups made from high-protein beans and thin protein syrups made from other proteins. Background technique: [0002] Rice bran generally accounts for 6% to 8% of the total weight of rice, but it contains 64% of the important nutrients of rice and more than 90% of the essential elements of the human body, including a large amount of sugar, fat and protein, and contains more Ash and vitamins. It is a by-product resource with extensive development value, and it is a hot spot in the research and development of food, beverage and health products. Existing rice bran protein extraction techniques mainly include alkali-dissolution and acid precipitation and enzymatic extraction. Alkali-dissolving and acid-precipitation method is used to extract rice bran protein, because of its hig...
