The technical scheme of technical solution problem of the present invention is:
The concentrated turbid juice preparation method of honey raisin tree comprises following steps:
1) remove seed by after the honey raisin tree cleaning destemming after maturation, smashed;
2) honey raisin tree of fragmentation is placed in 3---6 times of water, its temperature is 45---55 DEG C, soak 90---150 minutes;
3) honey raisin tree after immersion is squeezed the original just juice of honey raisin tree;
4) being added water by the pomace of squeezing out, (Novi's letter pulp enzyme specialized designs is for the treatment of the dipping of pulp and vegetable and plant tissue with pulp enzyme, greatly can increase the ability that liquid/solid is separated and the crushing juice rate improving fruit), slag: the ratio of water is 1:1, enzyme: the ratio of water is 1:15---20, lixiviate 30---45 minutes;
5) the honey raisin tree pomace of lixiviate is carried out twice pressing, filter after second time press juice mixes with first time press juice;
6) press juice filtered is by 85---and 95 DEG C, time 30---sterilization in 45 seconds, removes the microorganism in fruit juice;
7) by the juice extruding after sterilization and grinding, extruding and milling time are 30-45 minute;
8) concentrated extruding and the juice after grinding obtain the turbid juice of concentrated honey raisin tree.
The present invention concentrates the turbid juice preparation method of honey raisin tree, and described second time press juice filters after mixing with first time press juice, and filter method is that mixed liquor is filtered by 100 order-140 order piping filters.
The present invention concentrates the turbid juice preparation method of honey raisin tree, and described juice extruding and Ginding process carry out extruding and grinding for being sent in homogenizer by juice.
The present invention concentrates the turbid juice preparation method of honey raisin tree, described concentrated extruding and the juice after grinding, method for concentration is: described simmer down to economic benefits and social benefits concentration method, vacuum evaporation carries out evaporation and concentration, Vacuum Concentration pressure is 0.3-0.7Mpa, with 35 DEG C-42 DEG C for thickening temperature, evaporate 15-55 second, make extract concentration reach 50---60Brix.
The invention has the beneficial effects as follows:
The present invention concentrates the turbid juice preparation method of honey raisin tree and soaks through twice squeezing after raw material owing to adopting, and therefore raw material is able to higher usage use, and the method prepares the utilization rate that the turbid juice of honey raisin tree improves raw material, and its effect is as follows:
Because honey raisin tree is moisture lower, be difficult to press extracting juice, the turbid juice processing technique of concentrated honey raisin tree provided by the invention, by steeping 2-3 hour to honey raisin tree lixiviate in water, make to squeeze the juice smooth, initially the rate of being squeezed the juice is honey raisin tree raw material 5%-8%, solves the problem that honey raisin tree is not easily squeezed the juice, after acquisition is initially squeezed the juice, squeeze pomace to one further again add water and carry out twice pressing with pulp enzyme, improve the crushing juice rate of honey raisin tree.
