The home cooking conditions were simulated to study the loss of the DHA in alga oil,fish oil and blend oil in the cooking.The results showed the heating experiment and home cooking caused great loss of DHA in alga oil and fish oil,but the loss in low concentration DHA oil made by adding alga oil and fish oil to vegetable oil greatly reduced.Under the home cooking conditions,the loss of DHA in low concentration DHA oil was less than 5%,and the retention rate was more than 95%. |
