AI Technical Summary

Problems solved by technology

It is expensive and has a bitter taste after hydrolysis
The rice protein products produced by the existing technology have defects such as strong powder texture, difficulty in swallowing, and poor taste, so it is difficult to be directly used for preparing food, especially complementary food for infants and young children
Therefore, currently on the market, there are few infant foods with rice protein as the main raw material.

preparation example 2

[0071] Implement the following steps:

[0072] (1) With solid content of 12wt% processed thread rice protein pulp as raw material, the protein content in its dry matter is 82.4wt%, oil content is 4.6wt%, fiber content is 2.4wt%, ash content is 2.0%, starch The content is 5.3wt%;

[0073] (2) adjust pH: add sodium hydroxide to adjust the pH of the slurry obtained in step (1) to 9;

[0074] (3) Hydrothermal treatment: use a hydrothermal device to carry out hydrothermal treatment to the slurry obtained in step (2). In the treatment, the material temperature is 130°C, the treatment time is 90s, and the feed amount is 0.25m 3 / h, the back pressure is 0.35MPa;

[0075] (4) Dispersion: Utilize a high-speed disperser to disperse and homogenize the slurry obtained in step (3) at 500 rpm;

[0076] (5) Washing: Use 3.3 times the volume of water to wash the feed liquid obtained in step (4), and collect the insoluble components by centrifugation (7000g, 30s); use the same volume of wate...

preparation example 3

[0083] Be that 4.6wt% with water content, protein content be 72.7wt%, grease content be 4.1wt%, fiber content be 2.0%, ash content be 3.7wt%, starch content be the rice protein powder of 2.4wt% as raw material, implement following step:

[0084] (1) Slurry: add water to the rice protein powder to prepare a slurry with a dry matter content of 25% by weight;

[0085] (2) adjust pH: add sodium hydroxide to adjust the pH of the slurry obtained in step (1) to 10;

[0086] (3) Hydrothermal treatment: use a hydrothermal device to carry out hydrothermal treatment to the slurry obtained in step (2). In the process, the material temperature is 120°C, the treatment time is 220s, and the feed amount is 0.25m 3 / h, the back pressure is 0.2MPa;

[0087] (4) Dispersion: Utilize a high-speed disperser to disperse and homogenize the slurry obtained in step (3) at 450rpm;

[0088] (5) Washing: use 1.1 times the volume of water to wash the feed liquid obtained in step (4), and collect insolub...

Abstract

The invention provides a composition added with processed rice protein products. The rice protein composition is particularly advantageous as an infant food.

Description

technical field [0001] The invention belongs to the field of food compositions, in particular to a food composition prepared by using processed rice protein products. Background technique [0002] Infants and young children are the most critical period for human growth and intellectual development, and the delay in development during this period cannot be compensated in the following growth stages. Traditional infant formulas generally add milk protein, however, it is now considered that milk protein has certain allergenicity. In addition, 14% of infants and young children allergic to cow's milk were also allergic to soy-based formula (Bhatia J, Greer F; American Academy of Pediatrics Committee on Nutrition. Use of soy protein-based formulas in infant feeding. Pediatrics 2008 ; 121:1062–8.). The use of hydrolyzed milk protein can partially solve the allergenicity problem; however, the price of hydrolyzed milk protein raw materials is usually higher than that of ordinary mi...
