preparation example Construction

[0029] One aspect of the embodiments of the present invention provides a method for preparing nutrition-enhanced germinated brown rice compound instant rice, which includes:

[0030] (1) Provide germinated brown rice;

[0031] (2) adopt cellulase to carry out pretreatment to described germinated brown rice;

[0032] (3) placing the germinated brown rice obtained in step (2) in a nutrition-enhancing solution, and using ultrasonic waves to erode the germinated brown rice, at least forming osmotic channels for nutrients to pass through on the surface of the germinated brown rice;

[0033] (4) Vacuum impregnating the germinated brown rice obtained in step (3), at least making the nutrient elements permeate into the inside of the germinated brown rice, so as to obtain the nutrition-enhanced germinated brown rice;

[0034] (5) The nutritionally enhanced germinated brown rice and polished white rice are compounded and cooked to obtain the nutritionally enhanced germinated brown rice...

Embodiment 1

[0058] After the paddy is husked to obtain brown rice, remove miscellaneous rice, broken rice and immature grains, wash off the bran powder and dust on the surface of the rice grains, soak in 0.1% NaClO solution, rinse with deionized water, and spread the brown rice on a petri dish , after adding deionized water, place it in a constant temperature incubator to germinate, set the temperature at 25°C, wash the brown rice every 6 hours, wait until the bud length is 0.5-1mm, and the germination rate reaches 80%. When the germination is finished, wash it three times with deionized water and immediately put it into an oven and dry it at 50° C. for 5 hours to obtain germinated brown rice. Weigh 10.0kg of germinated brown rice, add 40L of cellulase solution with a concentration of 1.0ug / mL (adjust the pH to 5.0 with 0.04M sodium acetate buffer solution), hydrolyze for 60min in a water bath at 50°C, rinse with deionized water and soak in 50L of 5mg / L selenium and calcium ions, 5mg / LVB ...

Embodiment 2

[0060] After the paddy is husked to obtain brown rice, remove miscellaneous rice, broken rice and immature grains, wash off the bran powder and dust on the surface of the rice grains, soak in 0.1% NaClO solution, rinse with deionized water, and spread the brown rice on a petri dish , after adding deionized water, place it in a constant temperature incubator to germinate, set the temperature at 25°C, wash the brown rice every 6 hours, wait until the bud length is 0.5-1mm, and the germination rate reaches 80%. When the germination is finished, wash it three times with deionized water and immediately put it into an oven and dry it at 50° C. for 5 hours to obtain germinated brown rice. Weigh 10.0kg of germinated brown rice, add 20L cellulase solution with a concentration of 1.5ug / mL (adjust the pH value to 5.0 with 0.04M sodium acetate buffer solution), hydrolyze it in a water bath at 60°C for 40min, wash it with deionized water and soak it in 50L Contains 20mg / L selenium and calc...

Abstract

The invention discloses nutrition enhancement type germinated brown rice compound instant rice and a preparation method thereof. The preparation method comprises the following steps: pretreating germinated brown rice by the use of cellulose; placing the pretreated germinated brown rice into a nutrition enhancement solution, eroding the germinated brown rice by supersonic wave, and at least forming permeable pores for nutrient elements passing through on the surface of the germinated brown rice; carrying out vacuum impregnation on the germinated brown rice to at least make nutrient elements to permeate the germinated brown rice; and combining and cooking the obtained nutrition enhancement type germinated brown rice and white rice so as to obtain the nutrition enhancement type germinated brown rice compound instant rice. By combining enzymatic hydrolysis with cellulose, supersonic wave and vacuum impregnation and through the coarse grain and refined grain reasonable combined cooking mode, the instant rice obtained has high nutritive value, is convenient to carry, has good mouthfeel, and is convenient to eat.

Description

technical field [0001] The invention relates to an instant rice and a preparation method thereof, in particular to a nutrition-enhanced germinated brown rice compound instant rice and a preparation method thereof, belonging to the technical field of rice deep processing. Background technique [0002] In the process of grinding rice from brown rice to remove the germ and bran layer to obtain polished rice grains, there is a phenomenon of "over-refining" in processing, resulting in waste of food and loss of nutrients. Nutrients contained in the bran layer and germ of whole grains have been reported to have significant health benefits in humans. Regular consumption of whole grain foods can effectively prevent chronic diseases such as coronary heart disease, colon cancer, and diabetes. Brown rice is the hulled part of rice with the seed coat and is an important part of the whole grain. The nutritional value of germinated brown rice is higher than that of polished white rice. I...
