Advancement and utilization of astaxanthin

What Is Keto Diet plan

Astaxanthin is a non-vitamin . A source carotenoid, in animals body can not be converted to vitamin A. But . astaxanthin is a chain scission antioxidants, with strong antioxidant capability. . Animal tests reveal that astaxanthin can eliminate NO2, sulfide, carbides, but likewise . can reduce lipid peroxidation, reliable to inhibit lipid peroxidation induced by . complimentary radicals. Astaxanthin can reduce tumorigenesis, improve resistance, get rid of . totally free radicals, and many other physiological impacts, on UV-induced skin cancer . have excellent healing effect, on diabetic eye disease likewise have better control . function, in health chemicals, pharmaceuticals, cosmetics material, food additives, aquaculture also has broad application prospects.Chemical synthesis,

astaxanthin is the last . product of carotenoid synthesis, the ²- carotene transform into astaxanthin require . to add two ketone groups and hydroxyl. Chemical artificial is hard, and . most are the cis-structure. Artificial trans-astaxanthin is costly (now the . international market price is about $2,000/ kg), restricting their broader . application. At present, because of biological astaxanthin material is not high . enough, the chemical synthesis astaxanthin still has a competitive advantage.Biological extraction

, astaxanthin extracted from organisms . are trans structure ,
safe in usage and with environmentally friendly . nature, have broad advancement prospects. Existing biological sources of . astaxanthin mainly: astaxanthin providers extract from the wastes of fish processing industry and usage . microbial fermentation production, techniques are as follows: Extract astaxanthin from production and processing .
wastes, the existing global crab shrimp processing industry has

10 . million heaps aquatic shellfishes waste each year , with the polymerization system . can draw out astaxanthin from it, including astaxanthin esters and astacin, its . yield can as much as 153 micrograms/gram of waste.
It should be noted that the waste . will impact calcareous produce astaxanthin, therefore
, it needs to be removed as . far as possible while extracting. Practice has shown that adding an inorganic . acid or an organic acid in the silage process, will destroy the portion binding . of astaxanthin and protein or bone, therefore increasing the release of . astaxanthin.In lots of algae which can produce astaxanthin, . pluvialis algae are very crucial astaxanthin producing bacteria.
It was .

considered to be an astaxanthin microalgae which has industrial production . prospects. The algae not just can autotrophia, the heterotrophic life also can . be carried out. In the training process, if nitrogen deficiency, algae . accumulate in astaxanthin. Presently, the global good pluvialis algae contains . approximately 0.2% -2 %astaxanthin, typically accounts about more than 90% of total . carotenoids, and has the advantages of withstanding heat, much faster . development rate and simple cultivate outdoors and so on, are considered to be a type of great . potential algae used for mass production of astaxanthin.There are 2 bacteria pressures can produce . astaxanthin: one is mycobacterial lactic acid, it produces astaxanthin in .
hydrocarbon medium, and can not produced astaxanthin in nutrient agar; another . strain is short subtilis 103,
which grow in the oil, the final biomass . fermentation is 3g/L , coloring is just 0.03 mg/g. Source: http://www.cosprm.com- What Is Keto Diet plan
