Description

A kind of mushroom soybean crisp crust and preparation method thereof
Technical field
The present invention relates to a kind of mushroom soybean crisp crusts and preparation method thereof, belong to snack food processing technique field.
Background technology
As the improvement of people's living standards, the nutritive value requirement to snack food is also higher and higher.Crispy rice, as me State's traditional properties snack can directly eat or be used as dish dispensing(Such as tomato issshrimp with crispy fried rice crust), stopped by favorite Not busy food.Especially millet crisp crust with its it is crispy and delicious enjoy great popularity, the crispy rice of previous a variety of flavors was embodied in seasoning not Together, kind is substantially more single.
Edible mushroom has very high nutritive value, can adjust human metabolism, reduce as generally acknowledged excellent tonic product Blood pressure reduces cholesterol level, has a variety of diseases of prevention and treatment, the effect of promoting longevity.Mushroom is as the famous medicine food in 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 minerals, containing 18 kinds of amino acid, including eight kinds of necessary amino acid 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 rich in it is abundant be in fresh taste compound, especially flavor core Thuja acid and delicious amino acid rich content, have unique flavor.Mushroom adds deeply as the large edible mushroom of our province, abundance Work technical research is less.
Invention content
For the use for enriching the type of snack food, increasing its nutritive value, reducing chemical seasoning, the present invention provides A kind of delicious and crisp delicious in taste, nutritive value enrich and the mushroom soybean crisp crust of health.
The present invention also provides the preparation methods of above-mentioned mushroom soybean crisp crust.
The present invention is achieved by the following measures:
A kind of mushroom soybean crisp crust, raw material include:0.8 part of soy meal, 1.5 parts of wheat flour, 0.6-0.8 parts of mushroom;Institute Part is stated as parts by weight.The mushroom is dry product.Preferably, 0.8 part of soy meal, 1.5 parts of wheat flour, 0.7 part of mushroom.
Above-mentioned mushroom soybean crisp crust can also include 0.1 part of sesame.Seasoning can also be added to aggravate taste, it is described Seasoning can be salt, sugar, capsicum, cumin.
Mushroom in above-mentioned mushroom soybean crisp crust, which contains abundant vitamin, minerals and albumen, can improve mushroom soybean pot Bar nutriment, and protein from lentinus edodes include eight kinds must amino acid and ten kinds of nonessential amino acid, belong 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 cooperation of soybean, makes mushroom soybean crisp crust have unique flavor.Even if not adding seasoning, it still can meet and generally disappear Requirement of the person of expense to taste.
The present invention is had found by further research experiment, and dough is prepared by mixing into soy meal flour after mushroom enzymolysis, It can be further improved using the mouthfeel of the crispy rice prepared by vacuum frying, flavor;In addition, the addition energy of mushroom enzymatic hydrolysate Change ingredient, the performance of dough, and then significantly improve the mouthfeel of product(Brittleness).
So the preparation method of above-mentioned mushroom soybean crisp crust, preferably includes following steps:
(1)Mushroom after being soaked adds water to be digested after being beaten, and obtains mushroom enzymatic hydrolysate;Enzymolysis enzyme used includes protease;
(2)Mushroom enzymatic hydrolysate, soy meal and wheat flour (flour) are fabricated to dough, shaped cut sheets;
(3)It is sliced vacuum frying;Vacuum frying condition is:92 DEG C ~ 96 DEG C, 0.090 Mpa of vacuum degree of temperature, 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, Pass through deoiling treatment after vacuum frying;De-oiling condition is:0.090 Mpa of vacuum degree, 400 r/min of de-oiling rotating speed, the time 6 ~ 8min。
In above-mentioned preparation method, the effect of enzymolysis is to obtain more flavor substances;In addition, by enzymolysis change mushroom into Point, and then change the ingredient of dough, performance, so as to the mouthfeel for improving brittleness, significantly improving product.The effect of vacuum frying is to subtract Few flavor substance loss.Mushroom cooperation after soy meal and enzymolysis so that the smell and flavour of product further improve.
It is well known by those skilled in the art that enzyme has specificity, the flavor digested using different enzymes to mushroom Substance classes and content are different.And smell and flavour are generated with various flavor substances;The performance of dough is by it What ingredient determined.So different enzymes, causes the influence of the smell and flavour of product there are larger difference, to brittleness also different. The study found that it first uses cellulase, used again by neutral proteinase and trypsase with 2:The compound egg of 1 enzyme activity proportioning composition White enzyme, then with 5 ,-phosphodiesterase is digested, the content for obtaining part flavor substance in enzymolysis liquid improves, and various wind Matching between taste substance is relatively good, can generate the flavor and taste of more high praise.
Above-mentioned preparation method, enzymolysis step are preferably carried out using following manner:
The first step, cellulase degradation, the U/g of enzyme concentration 23 ~ 270,000,53 DEG C ~ 57 DEG C of hydrolysis temperature, 120 min of time;
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 forms;
Third walks, and 5 ,-phosphodiesterase enzymolysis, the U/g of enzyme concentration 55 ~ 650,000,65 DEG C ~ 75 DEG C of hydrolysis temperature, the 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 nutritional ingredients 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, it is unique and apparent fresh to have Taste and fragrance;
(3)The dosage of seasoning is reduced, more healthy;
(4)Mushroom addition manner is digested for mashing, and the mushroom after enzymolysis, which removes, contains a large amount of polysaccharide being easily absorbed by the body, more Peptide, amino acid, also containing abundant flavour nucleotide, delicious amino acid makes the richer delicious flavor of finished product;And it can be obviously improved Mouthfeel;
(5)By soybean according to special ratios and enzymolysis after mushroom be used cooperatively, can further improve product flavour and Smell(Flavor);
(6)Using specific enzyme and mode of action, so that the weight content of the flavor substance of product and proportioning reach It is optimal, flavour and smell(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 process is simple and environmentally-friendly, and with the advantages of convenient, nutritive value enriches.
