| The extraction process, fatty acid composition, oil performance and application of okra seed oil were summarized based on the research results in recent five years. The technology of extracting okra seed oil in laboratory was mature, and the yield could be improved by microwave and ultrasound wave, but the mass production technology needed to be strengthened. The okra seed oil was mainly composed of a variety of fatty acids, such as linoleic acid, oleic acid, palmitic acid and stearic acid, and the proportions of saturated fatty acids to monounsaturated fatty acids to polyunsaturated fatty acids in okra seed oil was close to 1∶?1∶?1. Okra seed oil was rich in essential fatty acids and antioxidants, which provided important physiology health function and value of application development, such as scavenging free radicals, protecting liver and repairing gastric mucosa, etc. The okra seed oil had advantages of stable performance and strong anti-oxidation, and its stability and anti-oxidation could be improved by microencapsulation and transformation of conjugated linoleic acid. In the end, reasonable suggestions were put forward for the future research direction on okra seed oil. |
