[USA] Alfa Chemistry announced that it has launched microalgae powder production services.
Alfa Chemistry is a high-tech company specializing in the cultivation of microalgae powder and the production of related natural extracts. It has obtained more than 75 patents in the breeding, cultivation, processing and extraction of microalgae, serving customers in the feed, food, nutraceutical and pharmaceutical sectors. At present, the annual production capacity of Alfa Chemistry’s microalgae and related natural extracts has exceeded 2,000 tons.
Microalgae are rich in nutrients, contain trace elements and various biologically active substances, and have the advantages of easy artificial propagation, fast growth and short breeding cycle. Microalgae has broad application prospects in energy and environmental protection, food industry, medical health, feed industry and cosmetics industry.
Energy and environmental protection
Microalgae biodiesel is expected to replace traditional fossil fuels. The organic matter such as lipids in the microalgae can be converted into a combustible liquid fuel by techniques such as transesterification and thermochemical decomposition. In addition to the lipids, other algal cell components (proteins, polysaccharides, etc.) can be pyrolyzed into bio-oil as well. Moreover, the microalgae consumes a large amount of CO2 while providing energy, which can effectively alleviate the greenhouse effect, and the microalgae can absorb nutrients in the sewage and purify the water.
Microalgae are rich in protein and oil, can be used as food for humans and various livestock, and can also be used to make various food additives. The combination of microalgae and other food ingredients not only retains most of the nutrients of the microalgae, but also enhances the nutritional value of the finished food products, including increased levels of protein, vitamins and trace elements. Microalgae have rich nutritional value, the most representative of which is Spirulina. Spirulina is rich in high-quality protein, γ-linolenic acid fatty acids, carotenoids, vitamins, and various trace elements such as iron, iodine, selenium, zinc, etc.
Microalgae contain antibiotics, antioxidants, anti-cancer and anti-viral components, and thus have great potential for medical applications. It also contains a variety of polysaccharides and proteins, which has anti-tumor, immune-enhancing and anti-aging effects. Studies have shown that feeding microalgae to animals can significantly increase the activity of T cells and B cells in animals, and the amount of d antibodies in body fluids is significantly increased. In addition, algal protein has a significant inhibitory effect on the in vitro growth of breast cancer cells (MCF-7) and liver cancer cells (HepG-2). Both algal polysaccharides and phycocyanin in microalgae can enhance the proliferation of bone marrow cells, promote the growth of immune organs such as thymus and spleen, and promote the biosynthesis of serum proteins.
The various biochemical components contained in the algae can provide the necessary nutrients for animals such as fish and shrimp, and can effectively promote the growth of animals. Astaxanthin is a component contained in general microalgae, and it has a certain influence on the accumulation of carotenoids in fish. In addition, chlorella is often used as a bait for rotifers and shellfish. Microalgae is widely considered to be an ideal feed for shrimp breeding because of its rich nutrition, strong palatability and good stability.
The polysaccharides and antioxidants contained in the microalgae have the functions of moisturizing, anti-ultraviolet radiation, anti-oxidation and the like. Microalgae reduces formation of pigmentation and wrinkles by inhibiting the oxidation of free radicals in the body and reducing the peroxidation of lipids. Studies have shown that the nutrient solution of spirulina can provide a variety of nutrients and active ingredients such as amino acids, algae polysaccharides, SOD, etc., which have the effects of increasing skin elasticity, moisturizing, and reducing wrinkles. Spirulina cosmetics have good permeability and have no irritation or sensitization to the skin.
Alfa Chemistry has researched and developed about 450 microalgae strains with high productivity. The main products of Alfa Chemistry include nannochloropsis powder, haematococcuspluvialis powder, dunaliellasalina powder, schizochyrium powder, spirulina powder, chlorella powder, DHA, EPA, β-carotene and astaxanthin,etc.
