It is a primary object of the present invention to provide a kind of preparation method of purple sweet potato fruity clear-juice beverage.
The present invention solve its technical problem used technical solution be:
A kind of preparation method of purple sweet potato fruity clear-juice beverage, includes the following steps:
1) it is placed after purple sweet potato picking 5-7 months, described is placed as under the conditions of 10-15 degree;Preferably 11-13 degree;
2) fruits and vegetables are added, additive amount accounts for 70-80% for purple sweet potato in mass ratio, and fruits and vegetables account for 20-30%;
3) ratio of solid material and water is 1.5-2.5:1,110-120 DEG C of vapor (steam) temperature, time 5-8 minute;
4) it is beaten, material is cooled to 75-85 DEG C later, adds in 500,000 active unit alpha-amylase 0.1-0.3%, and heat preservation is stirred Mix processing 50-70min;
5) feed liquid is cooled to 40-50 DEG C, adjusts pH value to 4.8-5.2, adds in 250,000 active unit pectase 0.1- 0.2%th, 200,000 active unit maltogenic amylase 0.3-0.5%, insulated and stirred processing 100-150min, press filtration juice;
6) 95-98 DEG C of boiling enzyme-removal temperature, time 2-5min;
7) after being cooled to room temperature, disk centrifugal, refined filtration are carried out successively, tubular type centrifugation concentrates, the disk centrifugal flow, 4000-8000 revs/min of rotating speed;The refined filtration is 1u refined filtration films;14000-20000 revs/min of tubular type centrifugal rotational speed;It is concentrated into Solid content is mass ratio 12-20%;
8) ultra high temperature short time sterilization.
In the present invention, the type of fruits and vegetables preferably includes at least one of strawberry, blueberry, yellow peach, mango, carrot.
In one embodiment, in step 7), 5000-7000 revs/min of the disk centrifugal rotating speed.
In one embodiment, in step 7), 14000-20000 revs/min of tubular type centrifugal rotational speed.
In one embodiment, it in step 7), concentrates and is concentrated for VO, until solid content 15-18%.
In one embodiment, in step 7), solid content is concentrated into as mass ratio 15-18%.
In one embodiment, in step 7), 123-125 DEG C of temperature, time 5-7 second.
Advantages of the present invention is as follows:
1st, it is placed in step 1), under purple sweet potato 10-15 degree 5-7 months, the starch in purple sweet potato is sufficiently converted into sugar, and does not have Corruption, quality is best at this time.
2nd, 75-85 DEG C of step 4) adds in 500,000 active unit alpha-amylase 0.1-0.3%, insulated and stirred processing 50- 70min;Step 5) feed liquid is cooled to 40-50 DEG C, adjusts pH value to 4.8-5.2, adds in 250,000 active unit pectase 0.1- 0.2%th, 200,000 active unit maltogenic amylase 0.3-0.5%, first with alpha-amylase by the straight chain and amylopectin in purple sweet potato It is degraded to glucose, maltose, maltotriose and α-limit dextrin;The pectic substance in potato meat is decomposed with pectase again;Maltose The main function of amylase is to inhibit age of starch;The ingredients such as the starch in purple sweet potato fully further are switched to sugar and are fully divided Solve pectic substance.
3rd, in step 7), disk centrifugal is carried out successively, refined filtration, tubular type centrifugation combination operation, disk centrifugal separator treating capacity is big, Can automatic discharge, be suitble to big volume low-concentration suspension carry out settlement treatment;The effect category of refined filtration (micro porous filtration) herein It is filtered in security personnel, the particle of 1 micron of diameter or more is intercepted;The rotating speed of tubular type separation is high, and separation is thorough, but operate, Clean relatively complicated, so it is placed in last clarifying treatment, can reach clear purpose can also reduce cleaning frequency Rate.
4th, the fruity purple sweet potato juice of present invention gained, straight drink is convenient, and natural fruity is dense, contains anthocyanidin, nutrient health, nothing Preservative is added, safety can carry out filling, room temperature transport, preservation with forms such as vial, pop can, Tetra Pak, PET bottles With sale, the shelf-life was up to 12 months.
