Will the nutrients from microalgae source become a trend in the health care industry?

With the increase of people's health awareness, seaweed products have been more and more attention and use by the health industry.


, the global al
gae market had a market capitalization of more than $
6
billion in 2015 and is expected to exceed $
11
billion by
2024
, according to the Transparency
report. Among them, microalgae (spirulina, globulin, salt algae and red splor algae) occupy the main market, spirulina and colium algae because of its unique protein, flour substitute function has been studied relatively thoroughly, widely used in the food and health care industry. In general, microalgae sources are partially produced on a large scale, such as
Omega-3
and seaweed salts. However, most microalgae sources also have developmental barriers such as carotenoids.DHAOmega-3
is an essential nutrient and currently the main sources include fish oil and krill oil. As global demand for
Omega-3
dietary supplements increases, people are looking for new sustainable alternative sources of
Omega-3
such as seaweed. In the case of microalgae, diatoms and whip caterpillar seaweed are rich in
EPA
and
DHA
. Polyunsaturated fatty acids from seaweed sources were initially concentrated on
DHA
, and the seaweed used was mainly fermented cleavage and iso-cured cocoon algae, while other seaweed rich in
DHA
also included the genus cystic pot and the genus Wicken."DHA
, a commercial edible
DHA developed by DSM, is derived from the above-mentioned species of seaweed, and its
DHASCO
products are derived from Koch's cryptic algae, of which
DHA
content exceeds
40%
, and safety and bioavailable performance, has been used in infant formula, infant food, dietary supplements and pharmaceutical fields. In addition, DSM has successfully extracted seaweed oil from the rip algae, of which the ratio of
DHA
and
EPA
is
2:1
.EPA EPA
-rich microalgae include triangular brown-fingered algae, micro-cyanobacteria and monocytobacteria, triangular brown-fingered algae is a natural
30-40% EPA
diatom, which has market potential for industrial scale production. The epa content of micro-
is
, although its development depends mainly on the external growth environment. Monocytobacteria, which rely on phototrophic cultivation, has been basically realized in the production of high-content
EPA
, but there are still some problems in its commercial scale production, such as the main obstacle to large-scale production of sputum microalgae source
EPA
is stability.alginateas an anion polysaccharide, seaweed acid is the main component of brown algae, accounting for about
40% of its dry
. Commercialized seaweed acid is usually extracted from
(
Lanariasp), giant algae and bubbly algae. Seaweed acid is commonly used as a thickener or gel in the food, beverage, cosmetic and pharmaceutical (including gastric flats) fields. Early studies have shown that seaweed acid may increase metal chelation, lower cholesterol absorption, regulate the composition of the gut bacterium and produce short-chain fatty acids. At the same time, seaweed acid also has the effect of increasing satiety, so it can be used in diet supplement product formulations with weight loss effect.recently, an in-body test showed that phosphate alginate molecules have the effect of reducing oxidative stress. Cell studies have also found that the molecule helps increase the anti-inflammatory properties of human cartilage cells, reduce gene expression and promote the synthesis of inflammatory cytokines in phagocytosphage cells. With the higher the degree of sulfuric acidization of seaweed acid molecules, the more effective they become. Studies have shown that sulphate seaweed acid may help relieve symptoms of osteoarthritis.astrenalineis a type of carotene, belong to the unsaturated compounds of terpenes. The sources of astalgine are composited and natural, the main sources of natural sources are extracted from microalgae such as rain-born red spline algae, astalgine accounts for
1.5-3% of its total dry mass
, while small sputal algae also contain this substance. Rainy red splor algae is a freshwater single-celled green algae, which exists in the form of swimming green nutrient cells under suitable environment, thick-walled spores in adverse environment, and appears red due to the accumulation of a large amount of astratin.Astoxycin can be used in a wide range of products, such as health products, cosmetics, food and feed farming, to play a variety of potential health benefits, including anti-inflammatory, anti-ulcer, immunomodulation, cardiovascular protection, light protection and chemical protection. At the same time, astrenaline can also pass through the blood-brain barrier of mammals, so it has a potential role in treating neurological diseases such as Alzheimer's disease. At present, most of the trials on the health effects of astrenaline are in-body and animal studies, which are still lacking in human clinical data.by contrast, synthetic astalgine has lower antioxidant properties than natural seaweed sources, possibly because the astalgine esterification form from seaweed sources is
95%
, and synthetic astalgine does not contain this form of ingredient. Because of its simple culture, low cost and high astratin content, rain-born red cyanobacteria is currently a hot research topic in the field of high yield of natural astratin. However, there are still some obstacles to large-scale production of natural astratin, such as low cell density and productivity, inefficient and ineffective cost culture, drying extraction techniques and pollutant residues.is afamily of carotenoids, whose distinctive yellow pigments can be used for dyeing food, pharmaceuticals, cosmetics and animal tissues. Loculin is the main component of retinal macular pigment, the human body itself can not synthesize flafonin, but can be supplemented by ingesting dietary supplements. Flavonin has an important role to play in eye health, especially in preventing and mitigating age-related macular degeneration (
ADM
) diseases, while also reducing the risk of cataracts. An earlier study in South Korea has also shown that small spter algae supplements can increase the amount of loatin in the serum. In addition, the removal of free-range properties of serotonin may provide cardiovascular health and chemical protection., the source of microalgae, has not yet achieved a large-scale production, with the most promising applications including small splor algae,
Scenedesmus sp
and
Muriellopsis sp
. If the economic cost problem is solved, the small spter algae grown by hetero-cultivation will accumulate to produce a large amount of lolatin. Compared with the yevan extracted from permaline, microalgae have a high growth rate, do not need land resources, need a small amount of water resources, while seaweed biomass can achieve year-round harvest. At present, there are still some problems with the leucin from microalgae sources, such as the low content of microalgae loatin, the higher harvest cost, the high demand for energy for cell division, the extraction process and so on.is similar toand loculin, and zeta is also a member of the carotenoid family, and the efficacy of the two in health care products is basically the same. Zelin is also present in the retinal macular pigment region, which has a light protection effect, but also can prevent
AMD
cataracts. Currently, corn yolks with market-oriented microalgae sources include
Dunalella sp
, copper-green microcystic algae and microcosm algae.
Dunalilla
is currently the main source of algae zetatin, which accumulates carotenoids in high-salt environments. At the same time, this type of seaweed has no cell wall, which is helpful for the extraction of corn yolk. The extraction of zephate from seaweed has not yet been commercialized, but recent studies have shown that the chemical mutagelation of ethyl acetate can increase the production of maize yellow from
D.tertiolecta
sources by
10-15%
. Although culture and extraction techniques are constantly improving, there is still a long way to go to achieve large-scale production of yelutin and zelin, the sources of seaweed., there are still practical application barriers to the development of large-scale market for microalgae-sourced nutrients. Recent studies have shown that optimizing production parameters can increase the yield of seaweed, which is related not only to the species of seaweed itself, but also to its concentration, culture temperature and culture patterns. At the same time, optimizing the production environment can also change the ratio
DHA
and
of
seaweed strains.
