The study looked at different types of perilla seeds in Korea to see how much oil they contain and what kinds of omega fatty acids are in the oil. They found that the oil content varied among the varieties, with some having more linolenic acid, which is a healthy omega-3 fatty acid. The ratio of omega-6 to omega-3 fatty acids also varied, with some varieties being better for health. The researchers also found that the amount of oil in the seeds was related to certain fatty acids, like stearic acid and linolenic acid. Overall, they discovered that perilla seeds have a high amount of unsaturated fatty acids, which are good for health.
