Algae have been part of the human diet since ancient times, with records in China dating back at least 2,500 years. In Europe, seaweed is used as a soil amendment and in some cases as feed. In Ireland, macroalgae organisms are used intensively as soil amendments. Microalgae began to be studied after the invention of the microscope in the 17th century. The first microalgae to be identified was the diatom Tabellaria in 1703. Research and commercial applications of microalgae and seaweeds have continued to evolve over the past 100 years. We already use algae in many different household and industrial products such as toothpaste, chocolate, milk, candy, cosmetics, ice cream, paints, inks and pharmaceuticals. Of the more than 70,000 different algae species known, less than 50 are currently used commercially, so the potential for applications is huge.
Nannochloropsis is a renewable and sustainable organism and can be used to produce high-value bioactive ingredients. According to persistence market research data, the global microalgae market is expected to grow at a compound annual growth rate of approximately 5% from 2020 to 2030, with the market value reaching US$5 billion by the end of 2031. Food and beverages will become the main application areas for microalgae products.
In September 2023, Nannochloropsis extract was officially accepted as a new food ingredient by the National Health Commission, and Nannochloropsis was approved as a new food ingredient in 2021. Nannothropsis gaditana, also known as Nannochloropsis, is a marine algae belonging to the genus Nannochloropsis of the family Unicellular Algae. Its cell size is about 2 to 4 m, which is 9 times smaller than red blood cells. It is typically green or yellow-green in color and is known for its production of PUFA (polyunsaturated fatty acids), high fat content (especially under nitrogen deficiency), and accumulation of various carotenoids. It grows quickly over a wide range of temperatures and can survive both lower and higher temperatures.
Pseudomonas micrococcus has many health benefits, including improved cardiovascular health, improved digestion, improved skin health, improved cognitive function, and improved immune system function. Additionally, it may help reduce inflammation, lower cholesterol levels, and reduce the risk of certain types of cancer. It may also help reduce the risk of diabetes, obesity and Alzheimer's disease.
Pseudomonas micrococcus can produce a series of pigments in high concentrations, such as astaxanthin, zeaxanthin and canthaxanthin, and is popular in European and American markets for its high protein, high unsaturated fatty acids and green nutrition. Many food companies have launched Pseudomonas micrococcus-related foods, focusing on fresh and healthy consumption concepts.
