1. Turmeric

Turmeric is the dry rhizome of Curcuma longa L., a plant in the genus Curcuma in the family Zingiberaceae. It is a traditional medicine with the same origin as medicine and food. The content of curcumin in turmeric is 3%-6%. The application of curcumin in the food field is mainly divided into three sections: colorants, seasonings and functional food raw materials. First of all, let me talk about the coloring agent. Turmeric is a pure natural yellow pigment, which is widely used in catering and various dosage forms of food; secondly, as a spice, turmeric is pungent, bitter, and mild in nature, and is often used as curry powder; in functional In terms of food raw materials, curcumin has physiological functions such as anti-inflammatory, anti-cancer, anti-oxidation, antibacterial, anti-viral, etc., and has obvious effects on the treatment of various diseases.


2. Turmeric Extract

Turmeric extract is an extract extracted from turmeric tubers. The main component of turmeric extract is curcumin, which is a slightly acidic diphenylheptane substance. It is an extremely rare diketone colored substance. A compound with a special structure of polyphenols.


Curcumin is an orange powder, bitter in taste, insoluble in water, soluble in ethanol, propylene glycol, glacial acetic acid and alkaline solution, but it will be reddish brown in alkaline environment, and yellow in neutral and acidic conditions. Therefore, when you use it, you should pay attention to whether the medium is oily or water-based, and there is also the problem of color change in the pH environment.


The production process of turmeric extract curcumin: turmeric raw material---crushing and sieving (24 mesh)---extraction (80% ethanol, micro-boiling extraction three times, each time 1.5h)---concentration (decompression is really fast Concentration)---filtration---separation and purification (DA201 macroporous resin enrichment or silica gel column chromatography)---eluent concentration---crystallization---high purity monomeric curcumin

3.1. The application of curcumin in the medical field

The application of gingerol in the field of medicine mainly utilizes its physiological effects such as anti-tumor, anti-oxidation and anti-inflammation. Clinical studies in recent years have shown that curcumin can be used in the treatment of various diseases such as tumors, cerebral infarction and hyperlipidemia, and it also has certain curative effects on hepatitis and ophthalmic diseases. In addition, related studies have also shown that curcumin has potential therapeutic effects on familial adenomatous polyposis, ulcerative colitis, bowel cancer, pancreatic cancer, hypercholesterolemia, atherosclerosis, pancreatitis, psoriasis, and arthritis , and a large number of clinical trials have proved that curcumin has good pharmacological properties, safety and tolerance.

3.2. Application of curcumin in cosmetic industry

Utilizing the antioxidant, anti-inflammatory, antibacterial and acaricidal effects of curcumin, it can be applied to the production of cosmetics. Studies have shown that curcumin and its derivatives have a good inhibitory effect on tyrosinase, and can also absorb ultraviolet rays, so they can be used in the production of cosmetics such as whitening, sunscreen and freckle removal. The gelatinase in the skin decomposes the fiber components such as collagen and elastin in the skin under the irradiation of ultraviolet rays, and curcumin can inhibit the activity of gelatinase, and then exert its anti-wrinkle effect.

3.3. Application of curcumin in animal feed

Curcumin has a positive effect on the growth aspects of animals. Studies have shown that the feed added with curcumin has a significant effect on the growth, production, immune function and other aspects of animals. The researchers have conducted experiments and found that curcumin can replace quinocetone (antibacterial drugs) in the feed of fattening pigs. This substitution effect not only does not affect the health of the pigs, but can also increase the daily weight gain of the pigs;
