Description
Technical field
The present invention relates to agricultural byproducts processing field, more particularly to a kind of preparation method of selenium-rich glutinous rice flour.
Background technology
Glutinous rice is called glutinous rice, because of its fragrant glutinous glutinous cunning, is often used to that local delicacies is made, deep to be liked by everybody.Modern science
Research shows：It is temperature containing nutritional ingredients such as protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin B2, volume starch in glutinous rice
Product are strengthened in reinforcement.In addition, the effects such as glutinous rice can play tonifying middle-Jiao and Qi, nourishing stomach and spleen, strengthening exterior and reducing sweat, antidiarrheal, antiabortive, detoxification sore treatment,
Available for the effect such as deficiency-cold gastralgia, gastric and duodenal ulcer, diuresis of quenching one's thirst, spontaneous perspiration due to deficiency of vital energy, acne rash carbuncle dothienesis.Glutinous rice is one
Kind gentle invigorant, have qi-restoratives, enrich blood, the effect such as invigorating the spleen warm stomach, hidroschesis.Suitable for the gastric disorder causing nausea caused by deficiency-cold in spleen and stomach, appetite
Reduce, the disease such as sweat void, powerless, the pregnant abdomen falling inflation of shortness of breath caused by diarrhea and the deficiency of vital energy.
China's selenium deficiency and low selenium area are in the great majority, the day minimum feeding selenium amount 50ug that Chinese Soclety of Nutrition is recommended, but into
People is mostly 26ug per daily ingestion selenium amount.Research shows that human body selenium deficiency can cause cardiovascular and cerebrovascular diseases, hypertension syndrome, stomach and intestine
More than the 40 kinds of disease such as tract disease, diabetes, asthma, Parkinson's, hepatopathy, cancer it is occurred frequently, have confirmed at present, selenium has
In terms of removing free radical, pre- anti-cancer, face nourishing antidebilitation, protection liver, resistance harmful heavy metal, radioresistance, immunological regulation
Important function.Selenium is to cancer, diabetes, asthma, hyperlipidemia disease, artery sclerosis, bad skin, cataract, kidney trouble, heart
Disease, hepatopathy, rheumatism, allergic constitution, arthritis, gastric ulcer, obesity, hypertension etc. all have very high prevention effect.It is glutinous
The viscosity of rice is big, is to make cake, Zongzi and the primary raw material on Lantern Festival.Selenium deficiency situation is improved by selenium-enriched food very necessary.
The content of the invention
It is an object of the invention to provide a kind of preparation method of selenium-rich glutinous rice flour, it is achieved through the following technical solutions：
A kind of preparation method of selenium-rich glutinous rice flour, comprises the following steps：Following raw material is taken, is prepared by following portions by weight：
120-135 parts of glutinous rice flour, 10-12 parts of watermelon seeds powder, 5-8 parts of seabuckthorn fruit powder, 4-6 parts of daisy_petal part alcohol extracting thing, pig kidney 3-6
Part, 0.2-0.5 parts of dietary fiber, 1.2-1.5 parts of chitosan, 1.5-1.8 parts of humulus grass, 100-120 parts of pure water；
1. fresh pig kidney is cleaned, is put into the sodium chloride solution that mass concentration is 0.5% and soaks 2-4 hours, then take out drip
It is dry, its 2-2.5 times of quality clear water is then added, then humulus grass is added, pig kidney humulus grass slurry is worn into, sterilize 3-5min at 96-98 DEG C；So
Complex enzyme is added in pig kidney humulus grass slurry afterwards, the 0.12-0.15% that pig kidney humulus grass starches quality is added to, in 42-45 DEG C, pH7.6-
7.8 times progress enzyme digestion reaction 2-2.2h, then go out enzyme 8-10min at 96-98 DEG C, then with 2500-3000r/min rotating speeds
12-15min is centrifuged, supernatant and sediment are collected respectively, supernatant is concentrated, is spray-dried, 150 mesh sieves is crossed, obtains
Extract A；Sediment is cleaned, is freeze-dried, pulverization process, cross 150 mesh sieves, obtain extract B；By extract A with
Extract B is uniformly mixed, and obtains pig kidney humulus grass processed material；
2. pure water is warmed to 40-45 DEG C, is incubated 10min, then add dietary fiber, chitosan, daisy_petal part alcohol extracting thing,
After pig kidney humulus grass processed material is well mixed, the glutinous rice flour, watermelon seeds powder, seabuckthorn fruit powder for then adding 100 mesh sieves are mixed, and obtain mixed
Close slurry；
3. mixing slurry is put into homogenizer, homogenization 2-4 times is carried out under 22MPa pressure；
4. particle is made in the mixing slurry input Fluidbedgranulatingdrier of homogeneous, crosses 20 mesh sieves, control water content in 10-12%,
Selenium-rich glutinous rice flour is obtained, food microwave sterilization machine is then placed in, control temperature sterilizes 2-4min at 60-70 DEG C；
5. by the selenium-rich glutinous rice flour quantitative vacuum packaging of sterilization, normal temperature storage, you can.
Further, the preparation method of the daisy_petal part alcohol extracting thing is：After the daisy_petal part is smashed to pieces, then using 75%
Concentration of volume percent alcohol solvent, by solid-liquid ratio 1:30, the refluxing extraction 2h at 47 DEG C, centrifuge to obtain supernatant, then through overwinding
Turn to be concentrated by evaporation, be then freeze-dried and be made.
Further, the complex enzyme presses 1 by subtilopeptidase A, trypsase, cellulase：2：1 mass ratio
Composition.
Selenium-rich glutinous rice flour Se content prepared by the present invention is 0.4-0.6mg/kg.
The beneficial effects of the invention are as follows：Selenium-rich glutinous rice flour prepared by the present invention is safe, can stimulate the appetite of a person sponging on an aristocrat,
By the synergy of the pig kidney humulus grass processed material of seabuckthorn fruit powder, watermelon seeds powder and preparation, tradition glutinous rice powder can be significantly improved
Viscosity, transparency, freeze-thaw stability and low temperature condensational growth, further improve the processability of glutinous rice flour, and energy
Enough mouthfeels for greatly improving glutinous rice flour.Selenium-rich glutinous rice flour prepared by the present invention rich in abundant Organic Selenium, by seabuckthorn fruit powder,
The synergy of watermelon seeds powder and the pig kidney humulus grass processed material prepared is easier to be absorbed by the body and stored in tissue, energy
Preferably participate in the vital movement of human body.By the coordinated effect between each composition in the present invention so that the selenium-rich of preparation
Glutinous rice flour can prevent or improve cardiovascular and cerebrovascular disease.
