AI Technical Summary

Problems solved by technology

The beneficial substances produced during the germination process will be oxidized during the long-term germination process, thereby reducing the quality
In addition, during the pre-gelatinization process, on the one hand, rice grains tend to stick together, causing the rice grains to break and affect the senses; on the other hand, it is easy to gelatinize unevenly, resulting in different taste and quality
At present, the packaging methods of germinated brown rice or pre-gelatinized brown rice mainly adopt vacuum packaging, or add iron powder (deoxidizer), the anti-oxidation effect is not significant; the quality preservation effect is 3 to 6 months

Embodiment 1

[0041] Embodiment 1, a kind of germinated pregelatinized brown rice production method, with brown rice as raw material, carries out following steps successively:

[0042] (1) Cleaning and disinfection:

[0043] Rinse the brown rice twice with tap water to remove impurities, and the amount of tap water used for each flush is twice the weight of the brown rice raw material;

[0044] Drain the water (until there is no more dripping); use ultraviolet light to irradiate the rice grains, and pass through ozone for disinfection for 10 to 20 minutes (specifically: put 200g of washed and drained brown rice into a closed container with a volume of 1000mL, and pass 6mg / L of ozone); brown rice after disinfection.

[0045] (2) Germination:

[0046] Add germination solution equivalent to 4 times the weight of brown rice raw material in the brown rice after disinfection treatment, under the condition of 30 ℃, avoid light, make rice grain germinate for 24 hours, change the germination solu...

Embodiment 2

[0060] Embodiment 2, a kind of germinated pregelatinized brown rice production method uses brown rice as raw material:

[0061] Step (8) is:

[0062] In the dried germinated brown rice grains obtained in step (7), uniformly add tea polyphenols and carry out vacuum packaging in sub-bags, and the added amount of tea polyphenols is 0.1% (that is, tea polyphenols account for 0.1% of the raw material weight of brown rice);

[0063] The packaging bag is also equipped with an independently packaged oxygen scavenger (reduced iron powder) and desiccant (silica gel desiccant). The dosages of oxygen scavenger and desiccant are both 1g / 500g.

[0064] The rest are equal to Example 1.

Abstract

The invention discloses a production method of pre-gelatinized germinated brown rice. The production method of the pre-gelatinized germinated brown rice comprises the following steps of taking brown rice as a raw material; washing and disinfecting the brown rice; adding a germinating solution into the disinfected brown rice, and carrying out germinating at 25-30 DEG C in the shade; drying the germinated brown rice until the water content is 25-30%, dishing off, and carrying out pre-gelatinizing; performing air shower on the pre-gelatinized germinated brown rice so that the rice grains are completely separated; drying the germinated brown rice grains in a circulatory ventilating-drying box until the water content is 12-14%; and finally, carrying out vacuum packing by using bags. The production method of the pre-gelatinized germinated brown rice is simple in processing steps, relatively short in time consumption, and reliable in processing processes; and the prepared germinated brown rice is easy to steam, relatively good in taste, high in storage stability, and capable of adapting to the needs of the fast-paced modern society.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method of germinated brown rice. Background technique [0002] Brown rice is more and more known as a new type of grain product with full nutrition retention. Compared with refined white rice, brown rice contains more protein, unsaturated fatty acid, crude fiber, V B1 , V B2 Vitamins, phosphorus, potassium, iron, sodium, calcium, magnesium and other mineral elements, as well as biologically active substances such as rice bran lipopolysaccharide, γ-oryzanol, ceramide, γ-aminobutyric acid and other components with high nutritional value. Germination treatment can further greatly increase the content and utilization rate of reducing sugars, essential amino acids and other nutrients in brown rice, γ-oryzanol and γ-aminobutyric acid and other biologically active substances, and reduce the content of anti-nutritional components such as phytic acid. [0003] Germ...
