Researchers receive microalgae biomass with carotenoid pigments for food stuff sector

2 min read

In the framework of the Chlorella microalgae cultivation approach, the researchers from Peter the Terrific St.Petersburg Polytechnic University (SPbPU) received microalgae biomass with a substantial content material of carotenoid pigments, which is acceptable for the meals marketplace. The exploration outcomes ended up printed Nov. 2020 in the scientific journal “Agronomy Research“.

The deterioration of the ecological status of city locations and the industrialization of the foods marketplace needs the more enrichment of the diet with biologically useful food stuff substances. These kinds of pigments as carotenoids, from which vitamin A is synthesized in the physique, are essential for human well being. Nevertheless, it is complicated to get hold of the carotenoids from natural resources, because it is destroyed due to the irradiation sources, substantial temperatures, and substantial acidity of the atmosphere. Thus it is needed to establish systems for its qualified shipping and delivery to the cells.

“The obtained biomass with a superior stage of carotenoids can be made use of in different sectors of the foodstuff and pharmaceutical industries as a dietary health supplement to reduce the vitamin A deficiency for young children and older people dwelling in regions with improved environmental worry. Also to prevent the chance of oncological disorders, “notes Yulia Bazarnova, Director of the Bigger College of Biotechnology and Foodstuff Technologies at the Institute of Biomedical Methods and Biotechnology SPbPU.

Scientists of Polytechnic University developed the regularity of the nutrient substratum, situations of illumination of the cell suspension of microalgae, selected the techniques of focus and dehydration of the received biomass, to intensify the biosynthesis of carotenoids.

Besides, the researchers are developing microencapsulated kinds of carotenoids for focused shipping and delivery to a variety of organs and tissues. Microencapsulated carotenoids are particles composed of a main (Chlorella microalgae carotenoid extract) shell (biodegradable material). Researchers are at this time negotiating with the foremost Russian bottled vegetable oil manufacturer about the implementation of the new technologies in the nourishment industry.


Biological and nutrition systems are one of the critical scientific locations of the 21st century. Researchers all around the earth are doing the job to increase and maintain human health and fitness. The tasks of the Better University of Biotechnology and Foodstuff Technologies SPbPU are pretty essential and promising. The scientific developments in this area qualified prospects to the gradual improvement in the top quality of life.”
