Abstract
A kind of preparation method of super-pressure coarse cereals rice is by cellulase, hemicellulase, is dissolved in the water at 45~65 DEG C, adds coarse cereals raw material after coarse cereals seed raw material soaking is handled；Extra-high tension unit is put into after being soaked again under environment under low pressure with water and carries out ultra high pressure treatment, obtains super-pressure coarse cereals rice.The present invention has that operating pressure is low, farthest retains the functional components in coarse cereals rice, the advantages of improving product nutritive value.
Description
Technical field
The invention belongs to a kind of processing technique field of coarse cereals rice, more particularly to a kind of making of super-pressure coarse cereals rice
Method.
Background technology
Coarse cereals refer to relatively small more of the cultivated area in addition to large grain such as paddy, wheat, corn and soybean
Kind grain yam bean class general name, mainly includes buckwheat, broom corn millet, barley, millet, glutinous rice, black rice, millet etc..In general, there is mouth
It is poor and with characteristics such as many unique physiological functions to feel coarse, digestibility, also there is referred to as coarse food grain.Contain what is enriched in coarse cereals
The nutritional ingredients such as protein, fat, vitamin, mineral matter, cellulose, it is often more important that contain functional components in coarse cereals, have
There is physiological function；As oat contains functional components beta glucan, there is reducing blood sugar and blood fat effect；Buckwheat contain feature into
Divide rutin and Quercetin, there is hypolipemic function.Therefore coarse cereals have special dietary function, in modern safety health food
With critical role.
In recent years, with the development of grain intensive processing, to adapt to requirement of the people to mouthfeel, polished rice, smart face are eaten
Ratio significantly rises.And the more parts containing nutriment paddy, wheat top layer of polished rice, the process in smart face take off
Go, cause substantial amounts of nutritive loss, cause deficiency, modern civilization diseases that people take in nutritional ingredient to increase.
Coarse cereals rice is using coarse cereals and rice as primary raw material, is matched with certain proportion, is processed using foods processing technique
Change the original texture of original coarse cereals, its starch pre-gelatinized is made in original form, or be granulated again and further change coarse cereals fibre
The granularity of dimension and albumen.Coarse cereals rice typically has that nutritive value is comprehensive, eating method is convenient, rehydration is good, and palatability is good
The features such as.
Existing coarse cereals rice mostly uses hot worked mode, makes the abundant pre-gelatinized of starch in coarse cereals.In addition as far as possible
Coarse cereals particle is set fully to be contacted with water, purpose increases gelatinization degree also for allowing starch fully to be contacted with water.
Respective physiological activator is typically contained in coarse cereals, has been the functional components of food therapy health effect.Such as buckwheat
Contain flavones ingredient rutin (cereal crops only have buckwheat to contain) in wheat, to maintaining antiotasis, reduce its permeability, reduce
Because the fragility of blood vessels that hemorrhagic disease or hypertension trigger has certain effect；Anthocyanin has Scavenger of ROS work(in black rice
Effect and antioxidation activity；It is all the important substance for participating in body metabolism that vitamin B1, B2 are rich in millet, and above-mentioned substance all belongs to
In heat-sensitive substance, to thermo-responsive, structure can be destroyed under high temperature, the destruction coarse cereals rice that hot worked mode can be different degrees of
The nutritional ingredient of meal.There are some researches show hot-working can substantially reduce the content of rutin contents in buckwheat, 11.91mg is down to from 60.11
Dry weight/100g, antioxidation activity can also decline；Black Rice Anthocyanin-rich is degraded in a heated state, when reducing degree with heating
Between it is relevant with temperature；Millet is heat-treated compared with undressed millet, steams and boils vitamin B1 in rear millet and dropped to by 11mg/kg
2mg/kg or so, non-heat treated mode more using being granulated again after coarse cereals rice crushing powdering in addition, to the matter of coarse cereals rice in itself
Structure destroys larger.
Superhigh pressure technique is a kind of non-thermal technology technology, is killed already applied to food industry as food in Japan and Europe
The big molecular modification such as bacterium and albumen, starch.The main component of coarse cereals cereal is starch.Superhigh pressure technique is applied to coarse cereals paddy
Thing, it may be such that the starch in cereal is gelatinized under high pressure.Compared with the starch after heat treatment, the gelatinization after ultra high pressure treatment
Starch can keep granular pattern and armorphous, even structure, and good penetrability, machinability is good, easy to digest and absorption.It is in addition, super
High pressure is non-thermal technology, can to greatest extent retain in coarse cereals cereal easily by the nutritional ingredient of thermal change, can at utmost protect
Hold the nutritive value of raw material.
CN103564344 discloses a kind of " a kind of coarse cereals rice and preparation method thereof ", is planted by coarse cereal powder, starch and solid
Thing oil is granulated through squeezing, maturing, cutting, dried, then bakes expanded gained.Be it is a kind of through hot-working prepare coarse cereals rice, thermal sensitivity
Nutriment such as rutin, anthocyanin etc. have loss, and the original flavor of coarse cereals rice also declines to a great extent.
CN105707679 discloses " a kind of super-pressure artificial various grains rice and preparation method thereof ", using rice, corn as original
Material, crush, be mixed into dough in proportion, through ultra high pressure treatment, then cut granulation, most produced afterwards after boiling, dry cooling
Product.Advantage is that cost of material is low, is a kind of reconstruction grain rice in itself, insufficient trophic component is single, and product nutritive value is limited.
CN103271300A discloses " coarse cereals rice and preparation method thereof ", with corn flour, millet powder, glutinous millet powder, oatmeal,
The coarse cereals such as sweet potato powder are primary raw material, are obtained using processing steps such as dispensing, steam heating, extruding cutting forming and template shapings
Product.Use hot-working and again the coarse cereals rice of granulating technique preparation.
In summary, existing super-pressure coarse cereals rice process technology has the following disadvantages, and one, require that ultra high pressure is big
In 400mpa, for extra-high tension unit, the technology and cost requirement required for more than 400mpa autoclave pressure material are higher；
2nd, existing super-pressure coarse cereals rice process technology is mostly granulated raw material is destroyed completely again, is largely destroyed former
There is the texture of raw material；3rd, hot-working is introduced in process, microwave, spray drying are required for higher temperature, to a certain degree
On destroy the functional components that raw material contains.
