Abstract

The invention provides a concentrated peach juice product and a preparation method. The concentrated peach juice is a concentrated juice which is prepared by adopting sodium D-isoascorbate to fix the color and pectic enzyme, amylase and protease to carry out hydrolytic treatment; the content of the solvable solid matter of the concentrated peach juice product is 40 percent to 60 percent and the pH value equals to 3.8 to 4.2. One important contribution of the invention lies in that the crushing of peaches is realized on the base of the selection of the color fixative, thereby greatly improving the color index of the concentrated peach juice, meanwhile, pectic enzyme, amylase and protease are utilized to hydrolyze the peach juice, thereby finally obtaining a concentrated peach juice product with high nutritive value, stable properties and good flavor and taste by adopting the techniques such as adsorption and hyperfiltration. Edulcorator and preservative need not to be added into the concentrated peach juice product, thus completely preserving the nature properties, satisfying the concept of green consumption in modern times and meeting the requirements of the flavor and taste of beverages after the concentrated peach juice is diluted.

Description

A kind of concentrated fruit juice of peach and preparation method
Technical field
The present invention relates to a kind of concentrated fruit juice of peach and preparation method, especially, belong to fruits and vegetables deep process technology field through the preparation method of the concentrated peach fruit juice of amylase, pectase, protease hydrolytic.
Background technology
Peach contains the mouthfeel of rich nutrient contents and sweet succulence, but peach is difficult to storage, rots easily, therefore develops the consumption demand that the concentrated fruit juice of peach beverage products is fit to people.Because various brands fruit juice is intensive day by day, product differentiation is the trend of dwindling.Under the situation stable in channel structure, that marketing is similar, the consumer pays attention to the quality and the intension of product itself more, therefore keep fruits and vegetables natural nutrition and color and luster to greatest extent, prolonging the pot-life is the important means that improves pulp or fruit juice product competitiveness.
The oxidizing brown stain reason of fruit juice is a lot, and the reason of most of brown stain is because aldehydes matter is produced quinone under oxidasic effect, regeneration hydroxyl quinone, and the hydroxyl quinone aggregates into brown pigment again.And and light, oxygen, metal ion, the pH value has direct relation.Use in the traditional handicraft VC and sodium sulfite as antioxidant to suppress juice browning, but final result or brown stain, because of plant contains ascorbic acid oxidase, when fruits and vegetables disorganization, when contacting with air again, can make ascorbic acid destroyed rapidly, and ascorbic acid itself can be oxidized and cause brown stain, this is that the fruit juice industry all not have the thoroughly problem of solution so far.
Summary of the invention
The object of the invention is to provide a kind of inspissated juice and preparation method of pure peach preparation, by selecting D-sodium isoascorbate and sodium phosphate trimer as color stabilizer, the combination enzymolysis processing of amylase, pectase, protease, to keep peach fruit natural nutrition and color and luster to greatest extent, to prolong the pot-life is the suitability for industrialized production that purpose realizes concentrated fruit pulp of peach.
Technical scheme of the present invention is achieved in that this concentrated fruit juice of peach, it is characterized in that: concentrated fruit juice of peach is to protect look through the D-sodium isoascorbate, pectase, amylase, protease hydrolytic are handled, and its soluble solid content is 40-60%, and pH is the inspissated juice of 3.8-4.2.
The preparation method of described concentrated fruit juice of peach, its feature comprises the steps:
A, raw material clean: after the prepared using brushing machine cleaned, the feeding ozone clean was removed peach hair, silt, the dirt on material fruit surface in 2-4 minute in the 4-5 ton is washed the fruit groove, entered to promote and spray Cleaning for High Capacity, guaranteed that fruit does not have agricultural residual appearance and do not have exogenous impurity, and is standby;
B, the softening processing of broken preceding process, softening temperature is controlled at 70-80 ℃, softening time 3-5 minute;
C, break process: the D-sodium isoascorbate that spray adds fresh fruit weight 0.3 ‰ protects look, and peach is become pulp with the double-roll crusher fragmentation, utilizes the screen cloth in 12mm aperture that peach-pit is removed;
D, squeeze the juice: the peach pulp is pressed extracting juice with squeezer;
E, enzymolysis: the peach squeezing juice added protease hydrolytic 0.5-3 hour after adding amylase, pectase, enzymolysis 0.5-3 hour again,
F, decolouring are handled: the peach squeezing juice of enzymolysis adds bentonite or charcoal treatment 1-3 hour;
G, pasteurize: squeezing juice carries out sterilization more than 30 seconds through temperature more than 95 ℃, is cooled to 45-55 ℃;
H, filtration: crust kills cooled fruit juice and filters through ultrafilter;
I, concentrated: is 10-60% by concentration evaporator to peach juice evaporation and concentration to soluble solid content;
J, filtration: adopt cardboard diatomite that the peach inspissated juice is filtered;
K, can store: the inspissated juice after the filtration is cooled to below 35 ℃, and is canned, in-18 ℃ of following stored frozen.
The preparation method of described concentrated fruit juice of peach, step B also add 0.3 ‰ citric acids, 0.3 ‰ sodium phosphate trimers are wherein a kind of or 2 kinds protect look.
The preparation method of described concentrated fruit juice of peach, the 0.001-0.05% that the described diastatic adding proportion of step e is the peach squeezing juice.
The preparation method of described concentrated fruit juice of peach, the adding proportion of the described pectase of step e are the 0.005-0.05% of peach squeezing juice.
The preparation method of described concentrated fruit juice of peach, the 0.002-0.2% that the described protease adding proportion of step e is the peach squeezing juice.
The preparation method of described concentrated fruit juice of peach, the additional proportion of the described active carbon of step F is the 0.05-0.5% of peach squeezing juice.
The preparation method of described concentrated fruit juice of peach, the 0.05-0.3% that the described bentonitic additional proportion of step F is the peach squeezing juice.
Fruit juice after also adopting polymeric adsorbent to ultrafiltration after the preparation method of described concentrated fruit juice of peach, step H filter carries out adsorption bleaching.
The preparation method of described concentrated fruit juice of peach, it is the 0.3-0.4mg/kg cleaning fluid that the described ozone of steps A feeds concentration.
A significant contribution of the present invention is to select to realize on the basis of color stabilizer the fragmentation of peach, make the concentrated fruit juice of peach lustre index that large increase arranged, the D-sodium isoascorbate that look is protected in the present invention's selection is a kind of oxygen consumption type antioxidant, under acid condition, can be transformed into the D-arabo-ascorbic acid.The D-arabo-ascorbic acid is a kind of stereoisomer of L-ascorbic acid, and the different anti-cup hematic acid oxidation resistance of D-with the sodium phosphate trimer combination with complexing function, can play good color-protecting function considerably beyond the L-ascorbic acid.
The present invention utilizes amylase, pectase, protease to the peach juice hydrolysis, and adopt technologies such as absorption, ultrafiltration finally to make to be of high nutritive value, proterties is stablized, flavor taste is all good concentrated peach juice product.Needn't add sweetener, anticorrisive agent in the concentrated peach juice product, keep the pure natural proterties, satisfy the modern consumption green idea, reach the local flavor and the mouthfeel of beverage requirement after the dilution.
