Abstract
Description
Technical Field
[0001] The invention relates to the technical field of chemical synthesis, and in particular to a fruit acid concentration and separation system. Background Art
[0002] Fruit acids are various organic acids extracted from fruits. They are active ingredients found in many natural fruits or yogurts. They include gluconic acid, malic acid, citrus acid and lactic acid, most of which are extracted from fruits. Fruit acids are widely used in many fields, such as cosmetics, beverages and medical cosmetology. The most commonly used ingredients are glycolic acid and lactic acid. Glycolic acid, also known as glycanic acid and glycolic acid, was first extracted from sugarcane and is the most widely used fruit acid product. Glycolic acid has the smallest molecular weight among fruit acids, so it is easiest to penetrate the surface of the skin and has the most obvious absorption effect. It is the fruit acid most commonly used in skin resurfacing.

Both methods will lead to a large loss of the aroma components of the juice and decomposition of the color, which will not only consume a lot of energy but also have high production costs.
