Abstract
A method for preparing the embryonic plumule of long-grained nonglutinous rice, which is rich in gamma-aminobutanoic acid, from the giant-embryo rice grains includes such steps as husking, germinating, taking embryonic plumule, defatting, immersing in water at 35-40 deg.C for 4-5 hr while controlling pH=5-5.5, sterilizing, drying, puffing and pulverizing. Its product has such functions as decreasing blood pressure and blood fat, regulating cardiac rhythm and hormone secretion, activating the functions of kidney and liver, and preventing obesity.
Description
(1) technical field
What the present invention relates to is a kind of processing method of food, specifically a kind of processing method that is rich in nutrition, has the food of certain health care.
(2) background technology
GABA has effects such as good hypotensive, reducing blood lipid, renal function activate, liver function activate, prevention of obesity.In rice, contain a certain proportion of GABA.But GABA amount contained in the rice is very low, and edible common rice can not reach the effect of illness prevention and fitness.
(3) summary of the invention
The object of the present invention is to provide a kind of content enrichment that makes the GABA in the rice, make it to have the good health care function, can be used as the method for the enriching gamma-aminobutyric aid from sprouting brown-rice germ of food or health products or their additive.
The object of the present invention is achieved like this: with giant embryo paddy is raw material, raw material is sloughed the coetonium brown rice that obtains through the processing of rice huller paddy earlier, brown rice is germinateed, get plumule and carry out ungrease treatment, place it in again and soaked 4-5 hour in 35-40 ℃ the water and control pH value, obtain the product of alpha-aminobutyric acid content through sterilization, dry, expanded, pulverizing again at 500-900mg/100g at 5-5.5.
The present invention can also comprise that some features are like this:
1, described ungrease treatment is to extract 2-2.5 hour down at 35-40 ℃ with the n-hexane solvent, is reducing pressure degreasing 8-10 hour.
2, described ungrease treatment is to adopt CO
2Supercritical extract.
3, described ungrease treatment is to adopt extruding defatting.
The present invention mainly concentrates in the plumule according to the GABA in the paddy, and the content of its GABA can improve greatly after the paddy germination, can reach 3 times characteristics before germinateing.By method of the present invention, paddy is made brown rice earlier, carry out germination treatment again, carry out enrichment processing again, make alpha-aminobutyric acid content reach 500-900mg/100g even higher, with its raw material or additive, food prepared therefrom or health products as food, health products, can play blood pressure, reducing blood lipid, adjusting arrhythmia cordis, regulate hormone secretion, make renal function strengthen, make the effect of liver function activation, prevention of obesity, and can bring into play multiple physiological hygiene function.
(4) specific embodiments
For example the present invention is done more detailed description below:
1, be raw material with giant embryo paddy, raw material is sloughed the coetonium brown rice that obtains through the processing of rice huller paddy earlier, brown rice is germinateed, getting plumule extracted 2-2.5 hour down at 35-40 ℃ with the n-hexane solvent, reducing pressure degreasing 8-10 hour, place it in again and soaked 4-5 hour in 35-40 ℃ the water and control pH value, obtain the product of alpha-aminobutyric acid content through sterilization, dry, expanded, pulverizing again at 500-900mg/100g at 5-5.5.
2, be raw material with giant embryo paddy, raw material is sloughed the coetonium brown rice that obtains through the processing of rice huller paddy earlier, and brown rice is germinateed, and gets plumule and adopts CO
2Supercritical extract places it in and soaked 4-5 hour in 35-40 ℃ the water and control pH value at 5-5.5, obtains the product of alpha-aminobutyric acid content at 500-900mg/100g through sterilization, dry, expanded, pulverizing again.
3, be raw material with giant embryo paddy, raw material is sloughed the coetonium brown rice that obtains through the processing of rice huller paddy earlier, brown rice is germinateed, get plumule and adopt extruding defatting, place it in again and soaked 4-5 hour in 35-40 ℃ the water and control pH value, obtain the product of alpha-aminobutyric acid content through sterilization, dry, expanded, pulverizing again at 500-900mg/100g at 5-5.5.
Claims (4)
1, a kind of method of enriching gamma-aminobutyric aid from sprouting brown-rice germ, it is characterized in that: with giant embryo paddy is raw material, raw material is sloughed the coetonium brown rice that obtains through the processing of rice huller paddy earlier, brown rice is germinateed, get plumule and carry out ungrease treatment, place it in again and soaked 4-5 hour in 35-40 ℃ the water and control pH value, obtain the product of alpha-aminobutyric acid content through sterilization, dry, expanded, pulverizing again at 500-900mg/100g at 5-5.5.
2, the method for enriching gamma-aminobutyric aid from sprouting brown-rice germ according to claim 1 is characterized in that: described ungrease treatment is to extract 2-2.5 hour down at 35-40 ℃ with the n-hexane solvent, is reducing pressure degreasing 8-10 hour.
3, the method for enriching gamma-aminobutyric aid from sprouting brown-rice germ according to claim 1 is characterized in that: described ungrease treatment is to adopt CO
2Supercritical extract.
4, the method for enriching gamma-aminobutyric aid from sprouting brown-rice germ according to claim 1 is characterized in that: described ungrease treatment is to adopt extruding defatting.
