Problems solved by technology

Its disadvantage is that the reverse osmosis concentration is carried out under relatively high pressure, resulting in the decomposition or uncontrollable change of some components or the volatilization of fragrance, which consumes a lot of energy

Embodiment Construction

[0010] As shown in the attached drawings, after picking the fresh aloe leaves, soak them in clean water for a period of time and wash them. Sterilize by soaking in sterilizing solution for 15 minutes, rinsing with clean water, cutting off the leaf sheath and leaf tip, trimming, peeling off the epidermis, cutting the mesophyll into 4-5cm pieces, mashing, and grinding into a colloid. Then biological depressing and decoloring, add 70-120 grams of pectinase per 1000 liters of the ground aloe vera leaf juice, keep it in a stainless steel buffer tank at 45-50℃ for 25-35 minutes, and cool it to room temperature naturally. The viscous aloe vera leaf juice becomes clear and translucent. The aloe vera leaf juice after biological decoagulation is filtered, the filtrate is centrifuged through a three-foot centrifuge to obtain the centrifuged supernatant, and the centrifuged supernatant is circulated and filtered through the ultrafiltration membrane to obtain the concentrated juice I and the f...

Abstract

The preparation process of nano concentrated aloe juice includes the following steps: cutting fresh aloe leaf into small blocks, pounding to make pulp, grinding, biologial depressing, adding pectinase in aloe leaf juice, heat-insulating for 25-35 min. in stainless steel buffer tank at 45-50 deg.C, naturally-cooling to room temp., making aloe juice transparent and clear, filtering and centrifugal-separating aloe leaf juice, taking out supernatant and making it pass through ultrafiltration membrane to obtain filtrate I and concentrate I, collecting filtrate I and making it pass through nano level filtering membrane to make circular concentration to obtain concentrate II, mixing two concentrates, sterilizing, freeze-drying and stabilization treatment so as to obtain the invented aloe juice

Description

Technical field [0001] The invention relates to a preparation process for extracting aloe juice from aloe leaves. Background technique [0002] Aloe extract is the main raw material in medicine, chemical industry and food. The key technical point of its manufacturing method is how to break the intercellular connections of the large parenchyma cells in the mesophyll, reduce the degree of coagulation, and facilitate extraction; the second is to concentrate them without destroying the effective ingredients. For the first point above, the common method is to reduce the pour point by instantaneous high temperature or adding chemical substances. The disadvantage is that the instantaneous high temperature will cause the destruction of some components and the loss of some aromatic components by volatilization. The pour point depressing effect is not ideal. The method changes its natural ingredients, which has a negative impact on the environment. The second general approach mentioned abo...
