Pharmaceutical extraction solvent extraction equipment industrial extraction of ascorbic acid
the ascorbic acid in nature with L type and D type two kinds, the latter has no biological activity. Vitamin C is the crystal plate is colorless, odorless, soluble in water, insoluble in organic solvents. Stability in acid environment, with oxygen in the air, heat, light, alkaline substances, especially by the oxidase and trace amounts of copper, iron and other metal ions exist, can promote the oxidative damage. Oxidase in commonly found in vegetables, the vegetables store has a different degree in the process of erosion. But in some fruit contains biological flavonoids, can protect its stability.
ascorbic acid in animals
vitamin C for antibodies and collagen formation, tissue repair, Including some REDOX effect) , metabolism of phenylalanine, tyrosine, folic acid, iron, carbohydrate, fat, protein synthesis, maintain immune function, hydroxyl and serotonin, full blood vessels, promote the heme iron absorption and so on necessary, at the same time also has antioxidant, vitamin C fight free radicals, inhibit the formation of tyrosinase, so as to achieve whitening, pale spot effect.
in the body, is effective antioxidant, vitamin C is used to reduce the oxidation of ascorbic acid peroxidase substrate stress. There are many important biological synthesis process also needs vitamin C to participate in the role.
because most mammals can rely on the liver to synthesize vitamin C, so there is no lack of problem; But humans, primates and the marmot a few animals does not own synthesis, must pass the food, drug, etc.
the role of ascorbic acid on plant
vitamin C is an antioxidant, can helps the plants resist drought, ozone and ultraviolet light. Vitamin C protect plants from harmful side effects in photosynthesis.
vitamin C can resist scurvy, therefore, also known as ascorbic acid. Is widespread fresh fruits and vegetables and one of many biological important vitamins, as a kind of highly active substances, it involved in many metabolic processes. In recent years in plant senescence and adversity and free radical damage theory study, vitamin C as an organism to corresponding member of the protection system of free radical damage, caused more people's interests. For the determination of its content, therefore, can be used as the important physiological index of anti-aging and resistance to adversity, to identify fruit quality, at the same time strain breeding has important significance.
ascorbic acid of two kinds of industrial extraction technology
vitamin C first extracted from plants and animals. Later developed chemical manufacturing, and manufacturing method of fermentation and chemical sharing. Now using solvent extraction method of centrifugal extraction machine, fermentation with microorganism or enzyme breaks down organic compounds into other compounds. There are two kinds of manufacturing method, vitamin C is a kind of fermentation manufacturing method, one kind is extracting solvent extraction separation preparation. Solvent extraction is based on a compound in two mutually miscibility ( Or slightly soluble) Solubility in solvent or the distribution coefficient of the different, make the ascorbic acid from within a solvent is transferred to another in a solvent separation method. Solvent extraction method to effectively reduce the vitamin C production cost, improve the production efficiency.
