Astaxanthin is a non-vitamin . A source carotenoid, in animals body can not be transformed 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 decrease lipid peroxidation, efficient to prevent lipid peroxidation induced by . totally free radicals. Astaxanthin can suppress tumorigenesis, improve resistance, eliminate . free radicals, and numerous other physiological results, on UV-induced skin cancer . have good restorative impact, on diabetic eye disease likewise have much better control . role, 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 need . to add 2 ketone groups and hydroxyl. Chemical artificial is difficult, and . most are the cis-structure. Artificial trans-astaxanthin is costly (now the . international market value is about $2,000/ kg), limiting their wider . application. At present, due to the fact that of biological astaxanthin content is low . enough, the chemical synthesis astaxanthin still has a competitive advantage.Biological extraction
, astaxanthin drawn out from organisms
. are trans structure
,
safe in usage and with environmentally friendly
. nature, have broad development potential customers. Current biological sources of
. astaxanthin mainly: astaxanthin suppliers extract from the wastes of fish processing industry and use
. microbial fermentation production, methods are as follows: Extract astaxanthin from production and processing
.
wastes, the existing international crab shrimp processing industry has
10
. million loads aquatic crustaceans waste each year
, with the polymerization system
. can draw out astaxanthin from it, including astaxanthin esters and astacin, its
. yield can up to 153 micrograms/gram of waste.
It ought to be kept in mind that the waste
. will impact calcareous produce astaxanthin, for that reason
, it needs to be eliminated as
. far as possible while extracting. Practice has proved that including an inorganic
. acid or a natural acid in the silage procedure, will damage the portion binding
. of astaxanthin and protein or bone,
therefore increasing the release of
. astaxanthin.In many algae which can produce astaxanthin,
. pluvialis algae are really important astaxanthin producing germs.
It was
.
thought about to be an astaxanthin microalgae which has industrial production
. potential customers. The algae not just can autotrophia, the heterotrophic life likewise can
. be performed. In the training procedure, if nitrogen deficiency, algae
. collect in astaxanthin. Currently, the worldwide
excellent pluvialis algae contains
. approximately 0.2% -2 %astaxanthin, typically accounts about more than 90% of total
. carotenoids, and has the advantages of resisting high temperature level, much faster
. development rate and simple cultivate outdoors and so on, are considered to be a kind of excellent
. potential algae used for mass production of astaxanthin.There are two germs strains can produce
. astaxanthin: one is mycobacterial lactic acid, it produces astaxanthin in
.
hydrocarbon medium, and can not produced astaxanthin in nutrient agar; another
. stress is brief 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 Keto Diet plan
