Problems solved by technology

[0003] Kidney disease patients have specific requirements for protein intake. Regular rice or noodles are used as staple food. Because it contains more plant-based protein, its amino acid composition is not reasonable. Long-term consumption will increase the burden on the kidneys and further worsen the condition. , seriously affecting the prognosis of patients

Abstract

The present invention relates to the field of nutritious food and discloses a preparation method of reconstituted rice suitable for consumptions of patients with kidney diseases. The preparation method comprises the following steps: S1, de-proteinizing: digestive proteases are used to remove proteins in rice; S2, pre-drying: the de-proteinized rice in the S1 is pre-dried; S3, texture reconstituting and protein replacing: a protein texture reconstitution liquid is used to conduct the texture reconstituting and protein replacing of the pre-dried and de-proteinized rice in the S2; and S4, the texture reconstituted and protein replaced rice is dried to obtain the reconstituted rice. The protein content of the product is similar to that of ordinary rice, plant proteins in the ordinary rice are replaced by high quality egg-white proteins, and at the same time, the reconstituted rice has nutritious compositions of the ordinary rice and can be used as staple food of the patients with the kidney diseases. Compared with the low-protein rice in market, the reconstituted rice is good in taste, the protein content is improved, the proteins are animal proteins with a high bioavailability, and the reconstituted rice does not cause additional burdens on kidneys of the patients with the kidney diseases.

Description

technical field [0001] The invention relates to the field of nutritious food, in particular to a method for preparing reconstituted rice suitable for kidney disease patients. Background technique [0002] Kidney disease is a high-incidence disease in my country, and survey data show that the incidence of kidney disease in my country is more than 10%. As the course of the disease progresses, patients will develop chronic renal insufficiency, especially in the later stages of the disease. Patients have stricter nutritional requirements. If food intake is not strictly controlled, it is very easy to cause malnutrition, repeated illnesses, and even more serious consequences. Chronic kidney disease has specific requirements for protein, sodium, potassium, calcium, phosphorus, etc. As for protein, in phase I-II, to prevent excessive intake of protein, 0.8-1.0 g protein / kg·d is enough. The protein intake in stages III to IV should be controlled at about 0.6g protein / kg•d, and high...
