Spirulina liquid extract description

Spirulina powder is extracted from spirulina, which contains not only a large amount of protein, but also many bioactive ingredients, such as spirulina polysaccharide (PSP), β- Carotene, phycobiliprotein, γ- Linolenic acid, endogenous enzyme, etc., therefore, it has the physiological effects of improving body immunity, anti-aging, lowering blood lipid, lowering blood pressure, promoting protein synthesis, anti-cancer, etc., and it is widely used in functional food, traditional Chinese medicine, etc.

Spirulina is a kind of multicellular filamentous microalgae, which is a genus of Cyanophyta, Metagonia and Characteridaceae. Spirulina has been paid close attention and highly appraised by many scientists and international organizations all over the world for its comprehensive and balanced nutrition and high value of disease prevention and health care. Nutritionists and medical scientists call it "the champion of nutrition on earth" and "the new star of drug source". The World Health Organization recognized spirulina as "the best health product for human beings in the 21st century" and "the future super nutritious food"; UNESCO recommends spirulina as "the most ideal and perfect food for tomorrow"; The FAO also solemnly recommended to the world that "Spirulina is the best food resource and food for the future".

Spirulina extract resource distribution

Spirulina is a multicellular filamentous cyanobacteria that grew 3 billion years ago and has some characteristics of many ancient primitive algae. There are more than 30 species of Spirulina, which are widely distributed in tropical, subtropical and warm temperate oceans, lakes, hot springs, especially saline lakes. At present, five species have been found in China. In recent years, spirulina has also been found in the near Arctic. This shows that spirulina is almost everywhere and can adapt to extreme environments.

chemical composition

Protein

The protein content of spirulina is 58.5%~83.4%, and the composition ratio of amino acids is appropriate. The content of eight essential amino acids for human body is close to or exceeds the composition ratio standard recommended by the Food and Agriculture Organization of the United Nations (FAO). The protein digestibility of spirulina is 75.0%, and the bioavailability is 68.0%. Therefore, it is considered to be the food with the highest protein content and the best quality known to mankind. The human essential amino Chemicalbook acid contained therein is very similar to the RDA value (human requirement) recommended by FAO and the World Health Organization, namely, isoleucine 4.1%~4.5%, leucine 5.8%~6.8%, lysine 4.4%~4.6%, phenylalanine 2.9%~4.4%, methionine 1.8%~2.4%, threonine 2.7%~4.1%, tryptophan 1.1%~1.6%, valine 4.8%~6.5%.

5.Bioactive substances

(1) Spirulina polysaccharide is a water-soluble polysaccharide isolated from spirulina. It has strong biological activity and is the main form of carbohydrate in spirulina, with a content of 2~4g per 100. It is composed of D-mannose, D-glucose, D-galactose and glucuronic acid. 1 g spirulina contains 170 mg of phycocyanin, which is more than 10 times that of ordinary vegetables.

(2) The study of active protein shows that the phycocyanin extracted from spirulina is not only a good natural pigment, but also can improve the immunity of organism, and it has obvious effect on inhibiting the growth of cancer cells.

(3) The fatty acids in spirulina are mainly unsaturated fatty acids, linoleic acid and γ- 2 Linoleic acid and linoleic acid are essential fatty acids for human body, which can be formed through EFA γ- 2 Linolenic acid, and finally produce prostaglandins, thus participating in regulating various basic physiological processes of the human body, including regulating blood pressure, cholesterol synthesis, etc., can prevent diabetes, cancer, obesity, skin aging, etc.

(4) The content of β2 carotene in Spirulina is 10 times that of carrots. β2 carotene is a good natural food coloring, and also has high nutritional value and medicinal value, β2 carotene is the precursor of VA, it also has anti-aging and cancer prevention effects.

Spirulina extract powder application

1. Food and health products

Spirulina is praised by FAO as the most ideal food for the future of mankind. As a rich and balanced protein supplement, spirulina is mostly put on the market in the form of powder, tablet or pill. The developed spirulina foods include spirulina powder, tablets, capsules, instant granules, beverages, oral liquids, beer, noodles, health salt, nutritional rice flour, ice cream, candy, chocolate and biscuits. Spirulina is also an ingredient in orange-flavored crackers and other types of confectionery, increasing protein content by 12% and 18%. It can also be used as a protein powder and macaroni ingredients (add 10% spirulina). The production of other fermented foods like cheese, yogurt and tofu also offers many possibilities for spirulina applications. The non-enzymatic biochemical process is used to separate the filamentous spirulina into single-cell spirulina, which is more convenient to prepare functional nutrient solution and easy to digest. In addition, by the extraction method, a decolorized spirulina powder (yellow-white) can be obtained, which is odorless and tasteless, and it is a unique ingredient for many foods such as soups, sauces, doughs, fast food and instant beverages and other foods.

2. Pharmaceutical industry

Spirulina is rich in active substances, which have special medical and health care effects on many diseases. It has significant anti radiation and anti mutation functions, and it can be used to prevent and treat cancer, anti-aging, enhance the immunity of the body and other functions.

3. Animal husbandry

Spirulina can significantly increase the daily weight gain of broilers, the egg production rate and survival rate of laying hens, reduce feed consumption, and improve carcass traits and egg yolk color. The results showed that 2% spirulina could increase the survival rate by 16.8% and the weight gain by 33.4%; Adding spirulina to the feed of laying hens can increase the egg production rate by about 10% and reduce the total feed to egg ratio by about 3%; Adding 1% algae powder to the diet of laying hens can greatly deepen the yolk color and change the commodity value of eggs; Adding spirulina to breeding chicken feed can increase egg production and hatchability.

Spirulina is also a high-quality food with high nutritional value, which can improve the survival rate of aquatic animals, especially marine treasures, reduce the cost of breeding, improve the immunity and vitality of larvae, improve the meat quality, increase the luster of fish, make ornamental fish beautiful and bright, and have good nutritional effects on abalone, shrimp, flat shellfish, pearl shellfish, etc.

4. Cosmetics industry

Spirulina can improve the immunity of skin cells, protect the skin's self-regulation function, prevent water loss, resist UV damage, eliminate free radicals on the skin surface, increase the synthesis of skin collagen, soften the cuticle, promote blood circulation and skin regeneration, play the role of wrinkle prevention, sun protection, radiation resistance, whitening, freckle removal, anti-aging, and promote hair growth.

5. Environmental protection

Spirulina has good nutritional value and medical value. However, with the gradual reduction of water body suitable for the growth of spirulina, how to reduce the site consumption and use industrial wastewater to cultivate spirulina has become a hot research direction in recent years. Because it needs to absorb a lot of nutrients in the process of growth and reproduction, it has the characteristics of fast growth and reproduction, strong adaptability, and higher fermentability. Therefore, spirulina is a promising microalgae for wastewater treatment. It not only has the ability to float, but also the filamentous spirulina can be easily separated from the culture solution and harvested. It can also secrete extracellular biological flocculants during the growth process, Thus, the wastewater treatment process is strengthened. The harvested algal powder is a kind of high-quality protein, which also brings benefits to the wastewater treatment project and opens up a new way to utilize the protein source of wastewater. Compared with the traditional three-stage treatment, the process of using spirulina to treat wastewater has the advantages of low cost, low energy consumption and high efficiency. It is an environmental engineering technology with great development potential.
