Abstract
The invention discloses maize germ instant powder containing xylooligosaccharide. The maize germ instant powder is prepared by the following method: uniformly mixing 60-80% of maize germ meal with 2-4% of xylooligosaccharide, 6-12% of xylitol and 12-25% of skim milk powder, and sterilizing to obtain the maize germ instant powder containing xylooligosaccharide. According to the maize germ instant powder containing xylooligosaccharide, which is disclosed by the invention, the maize germ meal is compounded with the xylooligosaccharide to greatly increase the absorption rate of protein in the maize germ and remedy the defect of low absorption rate of plant protein, and meanwhile, the xylooligosaccharide also has the functions of promoting gastrointestinal peristalsis, proliferating beneficial intestinal bacteria and relaxing bowels. The maize germ instant powder is hydrolyzed by papain to increase the content of soluble protein and enable the xylooligosaccharide to well play the function of prompting protein absorption; the maize germ instant powder is hydrolyzed by alpha-amylase and cellulose to improve the absorption of soluble sugar, improve the solubility of the corn germ meal, reduce the agglomeration rate of the corn germ meal and perfect the cooking taste of the maize germ meal.
Description
Technical field
The present invention relates to a kind of maize germ instant powder containing xylo-oligosaccharide, belong to food processing field.
Background technology
Maize germ is the byproduct of corn processing, must nutrient containing abundant human body, maize germ account for corn heavy 8 ~ 10%, every 100g maize germ is containing protein 20.5g, fatty 28.6g, carbohydrate 40.8g and abundant V
e, V
b, crude fibre and several amino acids, mineral matter.Common maize germ is processed as maize germ oil, maize germ after oil expression is called corn germ cake, crude protein content in corn germ cake is 23 ~ 25%, major part albumen is albumin and globulin, be rich in the amino acid of needed by human body, wherein lysine and tryptophane higher, amino acid composition is similar to Chicken Albumin, is a kind of good nutrition fortifier.
Xylo-oligosaccharide can promote digesting and assimilating of protein, and eliminates to the injury that liver, kidney, intestines cause in protein metabolism process, and therefore xylo-oligosaccharide is good absorbing proteins confactor.Meanwhile, xylo-oligosaccharide has good prebiotics effect, not easily digested absorption and directly enter in large intestine and be preferably Bifidobacterium and utilize, propagation human body beneficial bacterium, and suppresses the growing of other harmful bacteria, breeds.In addition, the soluble dietary fiber of xylo-oligosaccharide or a kind of high-quality, has promotion intestines peristalsis, Constipation, accelerates intestinal endotoxin and gets rid of, the health efficacies such as the generation prevented colon cancer.
Corn germ protein belongs to vegetable protein, compared with animal protein, vegetable protein absorptivity lower, and the insolubility albumen contained in maize germ also prevents human body to the absorption of albumen, and therefore, the nutritive value causing maize germ runs off.Meanwhile, in maize germ, content of starch is higher, easily lump, and maize germ contains more insoluble sugar and crude fibre when the corn plumule powder prepared of conventional art is water-soluble, therefore, brew and mouthfeel poor.These problems all reduce the nutrition of corn plumule powder and reconstitute quality.
Summary of the invention
For above-mentioned prior art, the invention provides a kind of maize germ instant powder containing xylo-oligosaccharide, it has advantages such as being of high nutritive value, nutrition is easily absorbed, prevented from caking, brew are good, mouthfeel is good.
The present invention is achieved by the following technical solutions:
Containing a maize germ instant powder for xylo-oligosaccharide, obtained by following preparation method:
(1) get corn germ cake, removal of impurities, water washing (preferably washing 3 times), after washing, add water (preferably the water of 2 ~ 4 times of weight), atmospheric cooking (preferably 10 ~ 20min), with the enzyme of deactivation maize germ self;
(2) corn germ cake after above-mentioned deactivation, add water (preferably the water of 3 ~ 5 times of weight), pulverizes (adopt beater to pulverize, pulverize twice), obtain corn germ cake suspension;
(3) the 0.5mol/L solution pH of corn germ cake suspension being adjusted to the configuration of 6.5(food-grade citric acid regulates), add the mesophilicα-diastase of 280 ~ 320U/g and the cellulase of 240 ~ 280U/g, constant temperature hydrolysis 50 ~ 60min, then 100 DEG C of enzyme 8 ~ 12min that go out at 55 ~ 65 DEG C; The 0.05mol/L the solution again pH of corn germ cake suspension being adjusted to the configuration of 7.0(food-grade NaOH regulates), add the papain of 2500 ~ 3500U/g, constant temperature hydrolysis 50 ~ 60min at temperature 55 ~ 65 DEG C, then 100 DEG C of enzyme 8 ~ 12min that go out, obtain corn germ cake suspension after enzymolysis;
Described mesophilicα-diastase, cellulase, papain are existing conventional products in prior art, the present invention's mesophilicα-diastase used and cellulase are Tai'an letter and get profit bioengineering Co., Ltd product, and papain is Guangzhou distant sky enzyme preparation factory product;
(4) corn germ cake suspension after above-mentioned enzymolysis, filters (preferably 100 mesh sieves) to remove bulky grain insoluble matter, and then 45 ~ 55 DEG C vacuumize dry concentrated, and being concentrated into solid concentration is 50%(mass percent), obtain corn germ cake concentrate;
(5) carry out defibrination with colloid mill to corn germ cake concentrate, then carry out high-pressure homogeneous process twice, pressure is 30 ~ 40Mpa for the first time, and second time is 25 ~ 35Mpa; After homogeneous, carry out spraying dry (spray-dired condition is preferably: EAT 180 ~ 200 DEG C, leaving air temp 80 ~ 100 DEG C), obtain corn germ cake powder;
(6) by mass percentage, get the corn germ cake powder of 60 ~ 80%, the xylo-oligosaccharide (cross 100 mesh sieves) of 2 ~ 4%, the xylitol (crossing 100 mesh sieves) of 6 ~ 12% and 12 ~ 25% skimmed milk power, mixing, mixing, sterilizing (preferred microwave sterilization), namely vacuum packaging obtains the maize germ instant powder containing xylo-oligosaccharide, and every packet content is 30g.
Described skimmed milk power is skimmed milk power conventional in prior art.
The preparation method of the described maize germ instant powder containing xylo-oligosaccharide, the same.
The described maize germ instant powder containing xylo-oligosaccharide, when taking, takes after mixing it with water with hot boiling water.
Maize germ instant powder containing xylo-oligosaccharide of the present invention, by corn plumule powder and Xylo-oligosaccharide compounded, the absorptivity of protein in maize germ can greatly be improved, make up the shortcoming that vegetable protein absorptivity is lower, xylo-oligosaccharide promotes gastrointestinal peristalsis in addition simultaneously, propagation intestinal beneficial bacterium, the effect relaxed bowel, thus make product have promotion protein adsorption and accelerate bidirectional modulation effect of enteron aisle toxic metabolic products eliminating.In technological improvement, the present invention uses papain to be hydrolyzed, and adds the content of soluble protein, makes xylo-oligosaccharide better play the effect promoting absorbing proteins; Use AMS and cellulase to be hydrolyzed, add the absorption of soluble sugar, improve the dissolubility of corn plumule powder, reduce its caking rate, what improve corn plumule powder reconstitutes mouthfeel.
