Method used for preparing aloe juice by refrigeration

Abstract

The invention discloses a method used for preparing aloe juice by refrigeration. The method comprises steps of a first extraction and a second extraction. The first extraction comprises following steps: aloe leaves are washed, and treated by instant high temperature sterilization, and blade base and blade tip are removed; the processed aloe leaves are cut into pieces, and then are added into a container, and are pressed as being added; the container filled with aloe leaves is placed outside at -10 to -30 DEG C for 6 to 8h of refrigeration, and then is thawed after complete refrigeration; the refrigeration and thawing process is repeated for 2 to 3 times so that pulp and juice of aloe will separate from leaf skin naturally, and the mixture is filtered so as to obtain aloe juice for further use; and then a second extraction is performed. The second extraction comprises following steps: aloe leaves are washed, and treated by instant high temperature sterilization, and blade base and blade tip are removed; the processed aloe leaves are cut into pieces, and then are added into a container, and the aloe juice obtained in the first extraction is also added into the container to full fill the container; the container is placed outside at -10 to -30 DEG C for 6 to 8h of refrigeration, and then is thawed after complete refrigeration; the aloe juice obtained in the first extraction is added into the container to full fill the container, and then the refrigeration and thawing process is repeated for 2 to 3 times so that pulp and juice of aloe will separate from leaf skin naturally, and the mixture is filtered so as to obtain purified aloe juice with purity of 100%. The aloe juice prepared by the method is excellent in quality, high in freshness, and low in production cost, and is not polluted.

Description

technical field [0001] The invention relates to the fields of health care, medical treatment, cosmetics and food, in particular to a freezing preparation method of aloe juice. Background technique [0002] Aloe vera is a folk medicine widely used all over the world. Aloe vera is alkaline. People who often use aloe vera can transform into a healthy state with weakly alkaline body fluids. A long time ago people began to study the chemical composition of aloe. So far, more than hundreds of chemical components have been extracted, separated, identified and determined from aloe plants, such as aloin, emodin glycosides, six-carbon sugar, polymer polysaccharides, aloe pavilion, aloe mildew, etc. There are also a variety of amino acids, minerals, trace elements, various vitamins and biostimulants that are necessary for the human body. The extraction of aloe vera leaves is getting more and more attention. It is described in the book "Aloe Therapeutics and Magical Uses" published by...

Problems solved by technology

The methods of preparing aloe juice in Guangdong and Northeast China are basically the same. The disadvantages are that the aloe juice obtained by adding preservatives is polluted by heavy metals and chemicals, and the freshness and quality of the aloe juice are affected. decrease, the overall production cost increases
