A kind of preparation method of nutritive konjak silk
Technical field
The present invention relates to food processing field, and in particular to a kind of preparation method of the konjaku silk rich in nutriment.
Background technology
With the improvement of people's living standards, people gradually start to pursue low in calories, nutritious, the high food of satiety
Product.Wheat bran is the good source for preparing compound sugar, and the combination of compound sugar, soybean and marine alga and konjaku preferably embodies meals fibre
The materials such as dimension are to human body lipid-loweringing, the effect of intestinal health.
Wheat bran, is the outmost epidermis of wheat;Wheat bran has many nutritive values.As being effectively improved constipation, internal courage is reduced
Effect of sterol.Also contribute to preventing the disease such as colon and rectum cancerous precaution breast cancer.In addition, wheat bran prepares compound sugar
Good source, compound sugar has good Bifidobacterium cultivation effect and low heat value performance.In addition, compound sugar is also lived with surface
Property, noxious material and pathogen in adsorbable enteron aisle can improve body resistance against diseases.
Soybean protein, its lysine content is higher than other cereal materials, if being applied in Flour product, not only can improve product
Product protein content, can be so that because processing characteristics, work in-process increases Flour product color, smell and taste and extends the Flour product shelf-life.
Marine alga, its nutritive value is very high, treats constipation, reducing blood sugar and blood lipid and excludes the radioactivity such as internal lead unit including anti-
Element.
Konjaku, it is a kind of radicant, is called glucomannan, with various disease-prevention health functions, Jing often to eat konjakus
Food is of great benefit to body.The bonding pattern of konjac glucomannan monose is similar with cellulose, can effectively suppress small intestine to courage
The absorption of the lipolysis material such as sterol, bile acid, promotes fat to excrete, and reduces fat, cholesterol and enters blood, reduces
Triglyceride in serum and cholesterol total amount, therefore preventing hypertension, high fat of blood and angiocardiopathy can be played a part of.
Research now for konjak products is very ripe, for example:There are some Chinese patent applications, but substantially
The thickening properties for being both for konjaku are studied.
The content of the invention
The present invention provides a kind of preparation method of nutritive konjak silk, wind nutritious using konjaku silk obtained in the method
Taste is unique, can reach that heat is low, the strong effect of satiety.
To achieve these goals, the technical solution used in the present invention is:A kind of preparation method of nutritive konjak silk, specifically
Step is as follows:
(1)It is 1: 10 according to solid-liquid ratio(kg/L)Ratio, water is added in wheat bran;Then according to feed liquid gross mass adds 10%
Compound bacteria inoculation, fermentation temperature be 32 DEG C, fermentation 2-4 days after, it is stand-by;Wherein, compound bacteria be trichoderma reesei, aspergillus niger it is mixed
Compound, trichoderma reesei is 1: 1 with the mass ratio of aspergillus niger;
(2)Soybean is milled, and crosses 80-100 mesh sieves and obtains defatted soy flour;Defatted soy flour adds 15 times of deionized water dissolvings, uses 6mol/L
Sodium hydroxide solution adjusts pH to 8.0, and 1-1.5h is extracted in stirring, and centrifugation separates supernatant, discards residue;With the lemon of 6mol/L
Acid solution adjusts the pH to 4.5 of supernatant, stirs 10-20min, centrifugation, the sediment deionized water after centrifugation
Again dissolve, freeze-drying, obtain soybean protein, it is stand-by;
(3)Soybean is dried to water content 8-12%, and 40 mesh sieves are crossed after crushing, and 30-40min is extracted at 50 DEG C with n-hexane is carried out
Degreasing, the consumption of n-hexane is 5 times of soybean volume;Bean powder after degreasing is added into the ethanol that 5 times of volume fraction is 60%
In, 10-14h is extracted under conditions of being maintained at 50 DEG C, then filter;Concentrating filter liquor obtains soyabean oligosaccharides syrup, and reclaims second
Alcohol;Syrup is concentrated to dryness, and powder product is obtained after crushing;
(4)From not damaged, without the fresh Amorphophallus rivieri for going mouldy, silt is washed away, scrapes off and length and width 4cm, the bulk of thickness 2cm are cut into after cortex,
Into hothouse;It is dried indoor temperature to control at 70-80 DEG C, needs 20-24 hours;Block after dried sends into pulverizer
Interior crushing, obtains konjaku flour;
(5)Konjaku flour is removed into impurity with the sieve of 80-160 mesh, konjaku powder is obtained;
(6)By step(1)、(2)、(3)、(5)The material for obtaining and seawood meal example 1 in mass ratio:(1-2)∶1∶1∶(1-3)It is mixed
Close, obtain mixture;Mixture is injected in the raw material bucket with mixer with the mass ratio that 1: 40 is pressed with water, start stirring 20min
Afterwards, 1.5-2h is stood, is fully gelatinized jellied giantarum paste;
(7)By the coagulator got ready be dissolved in solidification agent feeding device in, adjust pressure, flow, at the same start mixer and into
Type equipment, allows coagulator and giantarum paste to enter refining mixing in former simultaneously;
(8)Refine mixed food embryo Jing konjaku silks mould to inject in 95-100 DEG C of water, boil 10-15min;
(9)Konjaku silk Jing cold rinses cooling after boiling, be divided in soft bag, plus suitable quantity of water, Jing sealings, it is sterilized, be evil spirit
Taro silk finished product.
Beneficial effect:Compared with prior art, the present invention has following clear advantage:
(1)Soyabean oligosaccharides, wheat bran compound sugar are added, the compound sugar for making product is mutually supplemented, nutrition is more uniform rich
It is rich;
(2)Konjaku silk heat is low, and satiety is strong, meets the demand of contemporary people;
(3)Take full advantage of wheat bran, soybean this class material has saved to a certain extent cost, also improves economic benefit.
