Description
Technical field
The present invention relates to a kind of mushroom coarse cereals crispy rice and preparation method thereof, belong to leisure food processing technique field.
Background technology
As the improvement of people's living standards, requiring also more and more higher to the nutritive value of leisure food.Crispy rice, is used as me
State's traditional properties snack, can directly eat or as dish dispensing（Such as tomato issshrimp with crispy fried rice crust）, it is extensively ace-high stop
Not busy food.Especially millet crisp crust with its it is crispy and delicious enjoy great popularity, the crispy rice of conventional a variety of local flavors was embodied in flavoring not
Together, kind is substantially more single.
Edible mushroom is as generally acknowledged excellent tonic product, with very high nutritive value, can adjust human metabolism, reduction
Blood pressure, reduction cholesterol level, there is a variety of diseases of prevention and treatment, the effect promoted longevity.Mushroom is eaten as the famous medicine of China
Dual-purpose bacterium, taste is fragrant strongly fragrant tempting and rich in nutriment, and protein content is high, and fat content is low, and contains abundant vitamin
And mineral matter, containing 18 kinds of amino acid, including eight kinds of essential amino acids and ten kinds of nonessential amino acid, belong to L-type more
Amino acid, the higher utilization that is easily absorbed by the body of activity.In addition, mushroom is in fresh taste compound, especially flavor core rich in what is enriched
Thuja acid and delicious amino acid rich content, with unique local flavor.Mushroom is as the large edible mushroom of our province, and abundance is deep to add
Work technical research is less.
The content of the invention
For the use for enriching the species of leisure food, increasing its nutritive value, reducing chemical seasoning, the present invention is provided
A kind of delicious and crisp delicious in taste, nutritive value be abundant and mushroom coarse cereals crispy rice of health.
Present invention also offers the preparation method of above-mentioned mushroom coarse cereals crispy rice.
Technical scheme：
A kind of mushroom coarse cereals crispy rice, its raw material includes：1.0-1.2 parts of coarse cereal powder, 1 part of wheat flour, 0.9 part of mushroom；Coarse cereals
Powder：By millet powder, soy meal, sorghum flour, coarse rice powder, black bean powder according to 1:1:1:1:1:1 part by weight composition；Described part is
Parts by weight.The mushroom is dry product.
Above-mentioned mushroom coarse cereals crispy rice, it is preferred that 1.1 parts of coarse cereal powder, 1 part of wheat flour, 0.9 part of mushroom.
Above-mentioned mushroom coarse cereals crispy rice, its raw material can also include 0.1 part of sesame.Flavoring can also be added to aggravate mouth
Taste, the flavoring can be salt, sugar, capsicum, cumin.
Mushroom in above-mentioned mushroom coarse cereals crispy rice, which contains abundant vitamin, mineral matter and albumen, can improve mushroom coarse cereals pot
The nutriment of bar；And protein from lentinus edodes includes eight kinds of essential amino acids and ten kinds of nonessential amino acid, belongs to L-type amino more
Acid, the higher utilization that is easily absorbed by the body of activity；Flavour nucleotide and delicious amino acid rich content and special ratios in mushroom
The fragrance of coarse cereals coordinates, and mushroom coarse cereals crispy rice is had unique local flavor.Even if without flavoring, still can meet and typically disappear
The requirement that expense person suits one's taste.
The present invention is had found by further research experiment, and dough is prepared by mixing into coarse cereal powder flour after mushroom enzymolysis,
It can be further improved by the mouthfeel of the crispy rice prepared by vacuum frying, local flavor again；In addition, the addition energy of mushroom enzymatic hydrolysate
Change composition, the performance of dough, and then significantly improve the mouthfeel of product（Brittleness）.
So, the preparation method of above-mentioned mushroom coarse cereals crispy rice preferably includes following steps：
（1）Mushroom after being soaked add water mashing after digest, obtain mushroom enzymatic hydrolysate；Enzymolysis enzyme used includes protease；
（2）By mushroom enzymatic hydrolysate, coarse cereal powder and wheat flour（Flour）It is fabricated to dough, shaped cut sheets；
（3）Section vacuum frying；Vacuum frying condition is：92 DEG C ~ 96 DEG C of temperature, the Mpa of vacuum 0.090, time 8
min~10 min。
Above-mentioned preparation method, it is used be soaked after mushroom can be replaced with fresh mushroom.
In order to reduce the fat content of product, deoiling treatment is passed through after vacuum frying；De-oiling condition is：Vacuum
0.090 Mpa, de-oiling rotating speed 400 r/min, 6 ~ 8min of time.
In above-mentioned preparation method, the effect of enzymolysis is to obtain more flavor substances；In addition, by digest change mushroom into
Point, and then change the composition of dough, performance, so as to improve brittleness, significantly improve the mouthfeel of product.The effect of vacuum frying is to subtract
Few flavor substance loss.Mushroom after coarse cereal powder and enzymolysis coordinates so that the smell and flavour of product further improve.
It is well known by those skilled in the art that enzyme has specificity, obtained local flavor is digested to mushroom using different enzymes
The species and content of material and other compositions are different.And smell and flavour are produced with various flavor substances；Dough
Performance determined by its composition.So, using different enzymes, cause the smell and flavour of product to there is larger difference, right
The influence of brittleness is also different.Research is found, is first used cellulase, is used again by neutral proteinase and trypsase with 2:1 enzyme
The compound protease than composition living, then digested with 5 '-phosphodiesterase, obtains containing for part flavor substance in enzymolysis liquid
Amount is improved, and matches somebody with somebody relatively good between various flavor substances and other compositions, can produce the local flavor and mouthfeel of more high praise.
Above-mentioned preparation method, its enzymolysis step is preferred to use following manner progress：
The first step, cellulase degradation, the U/g of enzyme concentration 23 ~ 270,000,53 DEG C ~ 57 DEG C of hydrolysis temperature, the min of time 120；
Second step, compound protease enzymolysis, the U/g of enzyme concentration 140 ~ 1,600,000,53 DEG C ~ 57 DEG C of hydrolysis temperature, time 150
min；The compound protease is according to 2 by neutral proteinase and trypsase:1 enzyme activity ratio is constituted；
3rd step, 5 '-phosphodiesterase enzymolysis, the U/g of enzyme concentration 55 ~ 650,000,65 DEG C ~ 75 DEG C of hydrolysis temperature, time 150
min；
The enzyme concentration is relative to the mushroom or fresh mushroom after being soaked.Wheat flour is flour in the present invention.
Beneficial effects of the present invention：
（1）Product contains the nutrients such as abundant protein, dietary fiber, vitamin and trace element, and nutrition is rich
It is rich balanced；
（2）Containing flavor substances such as abundant amino acid, volatile materials and ucleotides, possess unique and obvious fresh
Taste and fragrance；
（3）The consumption of flavoring is reduced, more healthy；
（4）Mushroom addition manner digests for mashing, and the mushroom after enzymolysis, which is removed, contains a large amount of polysaccharide being easily absorbed by the body, many
Peptide, amino acid, also containing abundant flavour nucleotide, delicious amino acid makes the richer delicious local flavor of finished product；And can be obviously improved
Mouthfeel；
（5）By coarse cereals according to special ratios with enzymolysis after mushroom use cooperatively, can further improve product flavour and
Smell（Local flavor）；
（6）Using specific enzyme and mode of action, so that the weight content and proportioning of the flavor substance of product reach
It is optimal, its flavour and smell（Local flavor）Evaluation further improve；
（7）Fried mode be vacuum frying, realize frying action under relatively low oil temperature, make finished product nutriment loss compared with
It is small；
（8）In addition preparation technology is simple and environmentally-friendly, and with instant, the abundant advantage of nutritive value.
