Embodiment 1

[0047] (1) Mix water-soluble soybean protein and washed rice into water, and the mixing ratio of water-soluble soybean protein, rice, and water is 0.01:1:1.3;

[0048] (2) After the water-soluble soybean protein is completely dissolved, place it at 40°C for 30 minutes and stir it every 10 minutes;

[0049] (3) Cook at normal pressure in a rice cooker for 25 minutes; obtain anti-aging rejuvenated rice;

[0050] (4) Weigh an appropriate amount of anti-aging regenerated rice, store it at 25±1℃, 4±1℃, -18±1℃, and measure the fresh and anti-aging regenerated rice after storage for 1d, 3d, and 6d. Gelatinization degree and retrogradation degree; the ordinary rice obtained without adding water-soluble soybean protein was used as the control group. The measurement results are shown in Tables 1 to 4. Figures 1 to 3 .

Abstract

The invention discloses a preparation method of ant-aging retrogradation rice. The preparation method comprises the steps of: mixing water-soluble protein and cleaned rice into water until the water-soluble protein is entirely dissolved to obtain mixed rice suspension; performing insulating on the mixed rice suspension; and stewing the insulated mixed rice suspension to obtain the ant-aging retrogradation rice. Compared with the prior art, the proper water-soluble protein is added to the rice, so that not only can the protein in the rice be enhanced, but also the aging and retrogradation of the rice can be effectively delayed.

Description

technical field [0001] The invention relates to a method for preparing rice, in particular to a method for preparing anti-aging regenerated rice. Background technique [0002] my country is the country with the highest rice production in the world, and rice occupies a large proportion in my country's entire grain product structure. More than 1 / 3 of the people in our country eat rice as the staple food, and people are accustomed to using rice as a raw material to make white rice and rice , Zongzi, etc. [0003] The starch content in rice grains can reach 60-70%. During the cooking process of rice, the raw starch grains swell and rupture, and at the same time combine with water molecules to form a viscous solution. However, in the process of low-temperature storage, rice products are prone to aging. This is because the hydrogen bonds between starch molecules and water molecules are broken, and the hydrogen bonds between starch molecules are recombined, and the starch molecules...
