Brown Algae Extract

What is brown algae extract?

Brown algae extract is a higher-level component extracted from multicellular algae. Brown algae extract (algin, fucoidan, kelp starch and fucoidan) has been used as a potential green feed additive in livestock and poultry production. , has unique biological functions such as improving growth performance, enhancing body immunity, improving intestinal environment, promoting growth and reproduction, improving animal meat quality, and improving egg and milk quality. It has significant application effects in animal feeding and feed.

Brown algae is a type of multi-cellular algae, a type of large seaweed belonging to the Phylum Phaeophyta in the plant kingdom, and belongs to a relatively advanced group of algae. Brown algae is yellow-brown or dark brown because the content of lutein in the cells exceeds other pigments. Common brown algae include kelp, hijiki, wakame, fucus, sargassum, rat algae, etc. Brown algae is a very important marine resource due to its wide distribution, large yield and low price. Brown algae can not only be used as our daily food, but also has high medicinal value because it contains a variety of special active substances that are beneficial to the human body.

In addition to protein, vitamins, sugars, minerals and other nutrients, brown algae also contains active ingredients such as seaweed polysaccharide and brown seaweed polyphenols. Studies have shown that the active ingredients in brown algae extract have various functions such as enhancing the body's immunity, antioxidant, anti-viral, regulating blood sugar, lowering blood lipids, losing weight and cellulite, preventing osteoporosis, anti-tumor, etc., and are very beneficial to human health. effect. Therefore, brown algae are an important type of medicinal and food resources.

Benefits for skin?

The anti-aging benefits of Brown Algae Extract Powder have been demonstrated in cell culture and clinical trials. Detection experiments using cDNA showed that brown algae extract has the ability to restore gene expression in senescent cells to the levels of young cells. In addition, the clinical benefits of brown algae extract have been demonstrated in studies and measurements of skin barrier function, skin hydration, skin elasticity, and skin surface contouring (improvement of wrinkle shape). The joint effects of brown algae extract on skin hydration, skin elasticity, and skin surface contour confirm the interdependence between skin barrier function and skin mechanical properties. This conclusion was reached through experiments by Pedersen and Jemel.

In vitro test results confirmed that brown algae extract has effects on both keratinocytes and fibroblasts. Although it is difficult to accurately describe the mechanism of action of brown algae extracts, only oligosaccharides are found in brown algae extracts, and their effects can be explained according to different circumstances. On the one hand, Brown Algae Extract Powder is used to activate keratinocytes. On the other hand, when brown algae extract is used, the oligopolysaccharides contained in it can reach fibroblasts and then exert their biological effects. This may affect the metabolic activity of fibroblasts through the cascade signaling pathway. In fact, there is a good agreement between the signaling retellings in keratinocytes and fibroblasts during exposure to pressure or heat injury.

Dermatologists further evaluated the effect of improving skin smoothness, firmness, and wrinkle appearance visible to the naked eye according to the conditions in the raw materials and methods. According to dermatologist evaluations, after 60 days of applying the test sample containing brown algae extract, the skin's smoothness, firmness, and wrinkle appearance improved by 80%, 55%, and 55% respectively.

Composition

Algin is one of the main components of the cell wall of brown algae. It is a linear, unbranched, negatively charged polysaccharide compound. It was isolated from brown algae by the British Stanford in 1881. The molecular weight and M/G distribution of algin determine its physical, chemical and biochemical properties. The content of algin in algae is relatively high, accounting for about 40% of the total sugar content (dry weight), and the content in kelp is about 19.7%. It has a wide range of uses, so its industrial output is the largest. Algin has biological activities such as anti-tumor, immunity enhancement, growth promotion, blood lipid lowering, blood sugar lowering, and radiation resistance.

Fucoidan oligosaccharide (oligosaccharide) is an oligomer of algin and a functional oligosaccharide. Current methods to obtain fucoidan oligosaccharides include chemical degradation, physical degradation and biological methods. Fucoid oligosaccharides have low molecular weight, strong water solubility, high stability, and have many biological activities, such as lowering blood sugar, lowering blood lipids, antioxidant, antibacterial, promoting growth, enhancing immunity, etc.

Kelp starch is a water-soluble polysaccharide composed of glucose with a low molecular weight. Kelp starch is divided into two types, namely soluble kelp starch and insoluble kelp starch. The content of kelp starch in brown algae in my country is not much, and the content in kelp is generally about 1%. Kelp starch has antibacterial properties. Kelp starch is sulfonated to obtain kelp starch sulfate, which has the effects of inhibiting platelet aggregation, combating myocardial necrosis in experimental animals, and increasing plasma high-density lipoprotein levels, and is used to prevent and treat atherosclerosis. Hyperlipidemia, coronary heart disease, etc.

Fucoidan is an intercellular product inherent in all brown algae and present in the cell wall matrix. It is a water-soluble heteropolysaccharide. The content of fucoidan in kelp is generally 0.3%~1.5%. Fucoidan is mainly a sulfated polysaccharide based on fucoidan. Its main component is L-fucose-4-sulfate, followed by a small amount of galactose, mannose, xylose, glucose, and arabinose. Sugar, uronic acid and protein, K, Na, Ca, Mg and other metal ions have various biological activities such as anti-tumor, anti-coagulation, anti-thrombosis, anti-virus and enhancing the body's immune function.

Application of brown algae extract in animal production

Brown algae extract can affect changes in enzyme and protein expression levels, promote body growth and metabolic activities, improve animal growth performance, promote weight gain and improve feed conversion rate. In addition, fucoidan oligosaccharides can stimulate the differentiation and maturation of various immune active cells, such as monocytes and macrophages to secrete cytokines (TNF-α, IL-1 and IL-6, etc.), T lymphocytes, and B lymphocytes. , reproduction, so that the body's immune system can be restored and strengthened, and it can exert a variety of physiological activities through immune regulation.

Algin, fucoidan and fucoidan are potential soluble dietary fibers. They cannot be digested and absorbed in the small intestine. They reach the large intestine and are fermented and utilized by some microbial flora. They increase the content of short-chain fatty acids in the hindgut and reduce the intestinal The PH value of the intestinal tract will affect the balance of intestinal flora and its metabolites. Oligosaccharides can competitively bind to exogenous lectins and carry pathogenic bacteria out of the body through the intestines, thereby reducing the chance of pathogenic bacteria adhering to the intestinal mucosa. , and can even "elute" pathogenic bacteria that have adhered to intestinal epithelial cells. Therefore, brown algae poly(oligo)saccharides can be used as a potential prebiotic in animal feed.

Algin is a weakly acidic cation. When the feed enters the animal's digestive tract, it combines with nitrogen-containing substances to produce a bioelectromagnetic effect, forming an epithelial cell potential gradient, changing the isoelectric point of feed protein particles in the digestive tract, and regulating the acidity of the animal's body. Alkali balance, thereby improving its ability to digest, transport and absorb proteins and amino acids; at the same time, the cation exchange capacity of algin can be used to replace part of the phytate phosphorus in the feed, thereby improving the utilization efficiency of phosphorus. It can also stimulate the endocrine function of animals, enhance the immune function of the animal body, and improve the growth and production performance of animals.
