| Abstract: |
| The oil-tea camellia seed oil and olive oil were compared and analyzed according to the quality standards. The results showed that the characteristic indexes and quality indexes of oil-tea camellia seed oil and olive oil were similar. Oil-tea camellia seed oil had the characteristics of low iodine value, strong antioxidant capacity, good stability and high smoke point. Both oil-tea camellia seed oil and olive oil had high content of unsaturated fatty acids, and oleic acid was the most important fatty acid in these two oils. The content of oleic acid in oil-tea camellia seed oil was even higher than that in olive oil. The content of saturated fatty acid in oil-tea camellia seed oil was about 10%, which was lower than that in olive oil. Oil-tea camellia seed oil contained a variety of active nutritional ingredients such as polyphenols and flavonoids, and had high nutritional value. In addition, the problems that need to be improved in the current quality standard system of oil-tea camellia were pointed out. The study provided a reference for the deep development and utilization of oil-tea camellia seed oil. |
