| Summary: | This study aimed to optimize the process of obtaining
antioxidant extracts rich in β-carotene from the remaining biomass of
Arthrospira platensis. Optimal extraction procedures using ultrasound,
homogenization and temperature were investigated at the laboratory level.
The results demonstrated that the highest yield of β-carotene in the extracts
was obtained using 96 % ethylic alcohol at a temperature of +45 °C for
30 minutes and a biomass/solvent ratio of 1 : 50 g·mL-1 and 1 : 10 g·mL-1
.
The activity of the antioxidant enzymes catalase and superoxide dismutase
varied depending on the extraction method, and the highest activity was
obtained in the experimental variants that were placed at the temperature of
+35 °C and +45 °C. Considering the valuable biochemical composition and
enzymatic activity, the antioxidant extracts obtained have a relevant potential
for implementation in various fields such as animal husbandry, medicine and
food. |
