Embodiment 1

[0039] A reprocessed rice suitable for kidney disease patients and a processing method thereof, comprising the following steps:

[0040] Step 1. Pretreatment: Soak the rice (polished rice or brown rice can be selected), separate the soaking liquid, crush it, and grind it until the particle size is 100 mesh. The pure water is used for soaking, and the mass ratio of material to water is 1:6;

[0041] Step 2, protease hydrolysis and deproteinization: add pretreated rice, purified water and protease in proportion to the reaction tank, the mass ratio of purified water to rice is 5:1, and the amount of protease is 6% of the substrate protein mass, The protease is alkaline protease, the enzymolysis temperature is 30° C., pH 9.0, and the enzymolysis time is 3 hours. The protease is hydrolyzed and separated, washed, separated again, dried and pulverized. In this embodiment, three times of hydrolysis with alkaline protease can make the protein content of the obtained product as low as 0...

Embodiment 2

[0045] A reprocessed rice suitable for kidney disease patients and a processing method thereof, comprising the following steps:

[0046] Step 1. Pretreatment: Soak the millet, separate out the soaking liquid, crush and grind it until the particle size is 80 mesh, and use pure water for soaking, and the mass ratio of material to water is 1:5;

[0047] Step 2, protease hydrolysis and deproteinization: add pretreated millet, purified water and protease in proportion to the reaction tank, the mass ratio of purified water to millet is 7:1, and the amount of protease is 8% of the substrate protein mass, The protease is acid protease, the enzymolysis temperature is 40° C., pH 3.0, and the enzymolysis time is 4 hours. The protease is hydrolyzed and separated, washed, separated again, dried and pulverized. In this embodiment, acid protease is used for three times of hydrolysis, so that the protein content in the obtained product can be as low as 0.2%.

Embodiment 3

[0051] A reprocessed rice suitable for kidney disease patients and a processing method thereof, comprising the following steps:

[0052] Step 1. Pretreatment: Soak the dehulled wheat, separate out the soaking liquid, crush and grind it until the particle size is 90 mesh, and use pure water for soaking, and the mass ratio of material to water is 1:7;

[0053] Step 2, protease hydrolysis and deproteinization: Add pretreated peeled wheat, purified water and protease in proportion to the reaction tank, the mass ratio of purified water to peeled wheat is 8:1, and the amount of protease is 10% of the substrate protein quality. %, the protease is a mixture of papain, bromelain and flavor enzymes, the enzymolysis temperature is 45°C, pH 6.5, and the enzymolysis time is 5h. The protease is hydrolyzed and separated, washed, separated again, dried and pulverized. In this example, the above-mentioned proteases (papain, bromelain and flavor enzyme) are used for three times of hydrolysis, s...

Abstract

The invention provides a processing method of refined rice suitable for patients suffering from kidney disease. The processing method comprises the following steps: (I) carrying out pretreatment, specifically, soaking the cereal raw material, separating out soaking liquid, crushing and levigating until the particle size is 10-100 meshes; (II) carrying out protease hydrolysis deproteinization; and (III) carrying out dephosphorization: dephosphorizing the cereal raw material subjected to deproteinization in the step (II) by phytase hydrolysis, or addition of yeast for fermentation, or a composite mode of phytase hydrolysis and yeast fermentation, or a composite mode of yeast and lactic acid bacteria microbial fermentation or phytase hydrolysis, yeast and lactic acid bacteria microbial fermentation; separating, cleaning, separating again, drying and crushing; and (IV) performing sieving, mixing, hardening and tempering, preheating, gelatinization, extrusion forming and drying processing on the cereal raw material processed by the step (III) to obtain the refined rice. According to the method provided by the invention, the processes of deproteinization and dephosphorization of the cereal raw material can be finished at a time, the deproteinization rate and the dephosphorization rate are high, and food raw material and products are provided for the patients suffering from kidney disease and other diseases.

Description

technical field [0001] The invention relates to reprocessed rice suitable for kidney disease patients and a processing method thereof. Background technique [0002] Protein has important physiological functions, is an indispensable nutrient for maintaining human health, and is also the most important nutrient for maintaining life. However, clinical studies have shown that for patients with kidney disease, the intake of non-high-quality protein will increase the glomerular filtration rate, increase the secretion of urinary protein and urea, cause glomerulosclerosis, etc., thereby aggravating the condition. 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 intake is provided by rice. The diet of Chinese residents is mainly based on grains. Among cereal grains, rice and wheat account for the vast majori...
