Preparation method of rice suitable for patients with kidney diseases

Abstract

A preparation method of rice suitable for patients with kidney diseases comprises the following steps: (1) the rice is soaked in an aqueous solution with citric acid or hydrochloric acid for 3 minutes to 1 hour, wherein the concentration of the citric acid or hydrochloric acid in the aqueous solution is 0.05%-5%; the acidic aqueous solution is discharged, the rice is cleaned for 2-6 times and drained; (2) water, phytase and phospholipase are added into a reaction container holding the rice, wherein the mass ratio of rice to water is 1:1-6, the addition amount of the phytase is 1000-5000 U / kg rice, the addition amount of the phospholipase is 0.1%-0.6% of the weight of the rice, the reaction temperature is 30-60 DEG C, the pH value is controlled to be 4.0-7.0 during the reaction, the reaction time is 2-6 hours; the enzymolysis solution is discharged; (3) the rice is cleaned; and (4) the rice is dried. In the premise of ensuring the integrity of grain shape of the rice, most of phosphorus and protein in the rice are removed, with the maximum removal rate of phosphorus being up to 86%.

Description

technical field [0001] The invention relates to a method for preparing rice, in particular to a method for preparing rice for kidney disease patients. Background technique [0002] In recent years, the number of kidney disease patients in my country has increased year by year, and kidney disease has become one of the major diseases that endanger human health. The kidney is the excretory organ of the human body, and its main function is to excrete various metabolites of the human body, especially the metabolic waste of protein and minerals. Phosphorus is one of the most abundant elements in the human body. It is mainly transported from the intestines to the body, and most of it is excreted from the kidneys. Under normal circumstances, the phosphorus excreted by the human body through the kidneys accounts for about 70% of the total excretion, and the phosphorus excreted through the feces accounts for about 30%. However, patients with chronic renal failure often suffer from c...

Problems solved by technology

Among the above methods, the processing method of deproteinized rice only simply removes the protein, and does not involve the comprehensive removal of phosphorus, which may not fully meet the staple food requirements of kidney disease patients who have high requirements for phosphorus limitation; it is suitable for kidney disease patients. The processing method of remanufactured rice, the original rice is crushed, deproteinized and dephosphorized through multi-step treatment, and the process of multiple separations is cumbersome; other raw materials that are compounded are also prone to loss of natural nutrition through dephosphorization and other treatment processes, and many After this treatment, the raw materials are compounded, gelatinized, and extruded into granules. The appearance and taste of reprocessed rice are not easy to control, and the reprocessed rice made by this processing technology is complicated in process and lacks the taste of natural grains.
