Effect of oil extract biomass H. pluvialis on oxidation of vegetable oils
Keywords:
oxidation of lipids, oxidation inhibitors, biomass of mature aplanospor H. pluvialis; astaxanthinAbstract
Background. Oxidation of dietary fat is harmful process that leads to its unsuitability for human consumption. Herbal antioxidants are rarely used today, especially fat-soluble.
Material and methods. The antioxidant properties of the oil extract of mature biomass aplanospor H. pluvialis were studied, which is a source of carotenoids astaxanthin by the method of calculation of the number of absorbed oxygen per time during initiated oxidation of fat (oil) at elevated temperature.
Results. It has been determined that the induction period of oxidation of sunflower oil by an inhibitor of H. pervialis equals to 2400 c. Induction period compared with the control increases 2.2 times by introducing inhibitor. The calculation of chain termination constants k7, equals to 8.9 · 104, shows the efficiency of the use of biomass extract H. pluvialis as an inhibitor of oxidative processes.
Conclusion. Algal biomass oil extract of mature aplanospor Haematococcus pluvialis is characterized as middle power antioxidant and can be used as a comprehensive antioxidant supplement. Prospects for further research is the analysis of the oil extract biomass H. pluvialis as a source of antioxidants of the Third Kind and study of the antioxidant properties of the extract within the fat-containing foods.
