Within the framework of the Chlorella microalgae cultivation course of, the researchers from Peter the Nice St.Petersburg Polytechnic College (SPbPU) obtained microalgae biomass with a excessive content material of carotenoid pigments, which is appropriate for the meals trade. The analysis outcomes had been revealed Nov. 2020 within the scientific journal “Agronomy Analysis“.
The deterioration of the ecological standing of city areas and the industrialization of the meals trade requires the extra enrichment of the weight loss program with biologically useful meals substances. Such pigments as carotenoids, from which vitamin A is synthesized within the physique, are important for human well being. Nonetheless, it’s tough to acquire the carotenoids from pure sources, as a result of it’s destroyed because of the irradiation sources, excessive temperatures, and excessive acidity of the atmosphere. Subsequently it’s essential to develop applied sciences for its focused supply to the cells.
“The obtained biomass with a excessive degree of carotenoids can be utilized in varied sectors of the meals and pharmaceutical industries as a dietary complement to scale back the vitamin A deficiency for youngsters and adults dwelling in areas with elevated environmental stress. Additionally to forestall the danger of oncological illnesses, “notes Yulia Bazarnova, Director of the Greater College of Biotechnology and Meals Applied sciences on the Institute of Biomedical Programs and Biotechnology SPbPU.
Scientists of Polytechnic College developed the consistency of the nutrient substratum, circumstances of illumination of the cell suspension of microalgae, chosen the strategies of focus and dehydration of the obtained biomass, to accentuate the biosynthesis of carotenoids.
Moreover, the researchers are creating microencapsulated types of carotenoids for focused supply to numerous organs and tissues. Microencapsulated carotenoids are particles composed of a core (Chlorella microalgae carotenoid extract) shell (biodegradable materials). Scientists are at the moment negotiating with the main Russian bottled vegetable oil producer in regards to the implementation of the brand new expertise within the diet trade.
Organic and diet applied sciences are one of many key scientific areas of the twenty first century. Scientists all around the globe are working to enhance and protect human well being. The tasks of the Greater College of Biotechnology and Meals Applied sciences SPbPU are crucial and promising. The scientific developments on this space results in the gradual enchancment within the high quality of life.”
