At present, among all food sources, spirulina and other algae contain a lot of protein, which has great market demand potential.
It is predicted that the market scale of algae proteins such as spirulina will grow at a compound annual growth rate of 6.6% in the future.
Ultrasonic extraction and purification technology of algae proteins such as spirulina will also give play to the advantages of low extraction temperature, high extraction rate and short extraction time, which will press the acceleration button for high-quality development of the industry.
In recent years, with the increasing demand for nutritious and healthy products, algae products have attracted more and more attention from the market because of their rich protein.
According to relevant data, the global phycocyanin market scale in 20 18 was 690.8 million dollars.
Spirulina occupies a very high market share in algae products, accounting for more than 50% of the market income.
The global market is expected to grow at a compound annual growth rate of 9.4% from 20 19 and reach 629.6 million USD by 2025.
Spirulina is one of the microalgae produced on a large scale, and it is a very rich and comprehensive organism in nature. Spirulina is rich in high-quality protein and various trace elements.
Spirulina has become the source of protein, and attracted much attention in the food industry. It is considered as an algae with great potential to produce single-cell protein.
Nowadays, Spirulina has become the source of protein, which has attracted much attention in food processing industry, and it is considered as a kind of algae with great potential to produce protein.
At present, there are nearly 70 spirulina factories in China with an annual output of over 9,000 tons, accounting for more than 60% of the global market. It is a major producer of spirulina.
It is understood that the industrial chain structure of plant protein is agriculture and industry, while spirulina protein is purely industrial production, which is a combination of bioengineering and chemical engineering, getting rid of the traditional manual production mode.
However, it is not easy to produce protein from spirulina and realize large-scale production.
Previously, due to the technical level of biochemical separation and purification and the lack of research on spirulina, its production was limited to extensive farming, and the overall quality of the product was not high, and there was no deep processing, which led to its less use as a food raw material.
Therefore, from spirulina to food raw materials, many industrial chains need to integrate and purify related spirulina processing technology breakthroughs.
At present, spirulina has been successfully applied to the production of various food raw materials, and great progress has been made in the study of its cultural characteristics and metabolic mechanism, and the technical level of its separation, purification and extraction has been significantly improved.
For example, the preparation of spirulina protein powder involves extraction and purification technology. Spirulina protein solution can be thawed and extracted, then put into an ultrasonic separation and purification device to extract purity, and finally the purified protein solution is dried to obtain spirulina protein powder.
According to technicians, spirulina protein powder uses ultrasonic wall-breaking technology to extract phycocyanin from spirulina, which has the advantages of low extraction temperature, high extraction rate and short extraction time. It is a modern technical means to replace the traditional shearing process to realize efficient, energy-saving and environment-friendly extraction, and also solves the problems of long process route, long extraction period, high energy consumption and low production efficiency in the traditional separation and purification method of spirulina protein powder.
According to the National Nutrition Plan (20 17-2030), by 2030, the intake of animal protein should be reduced by 50%, and the reduced animal protein should be replaced by plant protein, and algae protein such as spirulina is one of the important substitutes.
Essentially, Spirulina and other algae are rich sources in protein, and it is expected that the protein market of algae will increase greatly in the next few years.
The progress of extraction and purification technology will also contribute to the high-quality development of the industry.
