Abstract:
Algae is of great national economic importance and is an ingredient for food production, as well as a source of marine hydrocolloids and various biologically active substances. There is a lack of studies on a significant floral diversity of the northern seas justifying the need not only to determine the species composition of mass red algae species, but also to scrutinize its chemical composition and methods to obtain sulfated polysaccharides for its further use in the food industry. The thesis presents the research results of the chemical composition of a natural mixture consisting of two species of red algae – Ptilota serrata and Ptilota gunneri, gathered in the littoral near Bolshoy Solovetsky Island in the period 2019–2023. The research demonstrated that there were no significant differences in the content of ash, protein, carbohydrates and fiber in the mixtures, depending on the month of gathering. When developing a production technology for a water-soluble polysaccharide from a P. serrata and P. gunneri mixture, a man revealed that the rational algae pretreatment mode was to maintain the pH medium, duration 1 hour, temperature (22 ± 2) °C. The polysaccharide extraction modes are the following: temperature (120 ± 2) °C, duration 1 hour and pH medium 7. To purify the polysaccharide extract, it is most rational to use activated carbon in an amount of 0.5–1.0% by extract weight, duration (60 ± 5) minutes, temperature (98 ± 2) °C. A man has to dry the water-soluble polysaccharide using freeze-drying or spray dryers. The authors recommend to use a water-soluble polysaccharide from a P. serrata and P. gunneri red algae mixture as a thickener in the food production such as fruit desserts, sauces and jelly-like soft drinks.
