Abstract

The present invention discloses a processing method for eliminating secondary sedimentation of concentrated apple juice, which comprises the following processing steps: fresh juice extraction, browning, pasting, enzymolysis, adsorption, ultrafiltration, concentration and finished product packaging, wherein apple juice is put in an apple juice collecting tank for 0.5 to 1.5 hours; the apple juice is fully browned; the pasted apple juice enters an enzymolysis tank, and a pectic enzyme and amylase are added in the enzymolysis tank for 1 to 2 hours; 120 to 200 meshes of active carbon is added, and the adsorption is kept for 6 to 8 hours. The present invention is an effective processing method for eliminating secondary sedimentation of concentrated apple juice, and thus, the inner quality of the concentrated apple juice is improved.

Description

A kind of processing method of eliminating the concentrated apple clear juice secondary precipitation

(1) technical field:

The present invention relates to the fruit juice processing technique field, is a kind of processing method of eliminating the concentrated apple clear juice secondary precipitation specifically.

(2) background technology:

At present, in the deep processing industry of apple, industrialization level is higher, the anti-brown stain of enzyme that the conventional processing technology of its concentrated apple clear juice is that aquatic foods are squeezed the juice, gelatinization is gone out simultaneously, enzymolysis, absorption, ultrafiltration, concentrate, finished product, the concentrated apple clear juice of its processing is prone to mist after storage, promptly be called secondary precipitation, had a strong impact on the inherent quality of concentrated apple clear juice, thereby the processing method of a kind of effective elimination concentrated apple clear juice secondary precipitation was not seen at present.

(3) summary of the invention:

Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, and the processing method of a kind of effective elimination concentrated apple clear juice secondary precipitation is provided, and has mainly solved secondary precipitation appears in existing concentrated apple clear juice when storing problem.

In order to achieve the above object, the present invention is achieved in that a kind of processing method of eliminating the concentrated apple clear juice secondary precipitation, and it comprises following processing step:

A, aquatic foods are squeezed the juice, and fruit, broken, squeezing back one-tenth fruit juice are examined really, washed to the raw material apple, are stored in the fruit juice collecting tank;

B, brown stain places the fruit juice collecting tank to park 0.5-1.5 hour fruit juice, makes fruit juice carry out abundant brown stain;

C, gelatinization is warmed up to 80-85 ℃ with the fruit juice after the brown stain, is cooled to 50-55 ℃ then;

D, enzymolysis, the fruit juice after the gelatinization enters enzymatic vessel, adds pectase, amylase in enzymatic vessel, behind the reaction negative, parks 1-2 hour, adds 120-200 order active carbon, and absorption was stablized 6-8 hour;

E, ultrafiltration with the fruit juice that obtains behind the enzymolysis, is carried out ultrafiltration through the milipore filter of ultrafiltration system, apple clear juice;

F concentrates, and the above-mentioned apple clear juice that obtains is concentrated, and gets inspissated juice, is collected in the finished product jar;

G, finished product, the inspissated juice in the above-mentioned finished product jar becomes finished product by the aseptic filler can after high-temperature short-time sterilization.

For the further above-mentioned purpose that realizes, a kind of processing method of eliminating the concentrated apple clear juice of secondary precipitation of the present invention, the storage period of fruit juice in the fruit juice collecting tank is 1 hour among its described brown stain processing step b; Among its described processing step d, add 120 order active carbons, the addition of active carbon is 8-15Kg/20T, and measuring good addition is 10Kg/20T, and absorption, stabilization time are 6 hours.

A kind of processing method of eliminating the concentrated apple clear juice of secondary precipitation of the present invention is to adopt to make the abundant brown stain of fruit juice earlier, changes anti-brown stain technology in the past; Parked behind the enzymolysis 1-2 hour, and made the abundant enzymolysis of fruit juice, add adsorbent immediately behind the change reaction negative in the past; Prolong the absorption stabilization time of activated carbon of sorbent, thereby can effectively eliminate concentrated apple clear juice is prone to secondary precipitation after storage problem.

Compared with the prior art a kind of processing method of eliminating the concentrated apple clear juice secondary precipitation of the present invention has outstanding substantive distinguishing features and marked improvement, and 1, adopt abundant brown stain technology in early stage, make the abundant brown stain of fruit juice; 2, parked after the enzyme digestion reaction feminine gender 1-2 hour, add adsorbent again; 3, prolong absorption, stabilization time, adopt absorption, stabilization processes technology, thereby improved the inherent quality of concentrated apple clear juice, make it eliminate secondary precipitation after storage, its result of the test sees Table 1.

The absorption of concentrated apple clear juice, stability test be table 1 as a result
