Perilla seed is the dry mature fruit of Perilla frutescens, a plant of Labiatae.
Clinical names include Perilla frutescens, fried Perilla frutescens, honey fried Perilla frutescens, Perilla frutescens cream.
Spicy, warm sex, belong to the lung meridian. The effect is to reduce Qi and phlegm, relieve cough and asthma, and moisten intestines. Perilla seed contains 17% protein, 51.7% oil, 56.8% unsaturated fatty acid and linolenic acid, 17.6% linoleic acid.
Perilla seed oil
Perilla seed oil is a kind of mature seed oil with high unsaturation.
The main component of Perilla frutesccns is alpha-linolenic acid. The content of perilla seed oil is as high as 50%-70%. Perilla seed oil is the most abundant edible vegetable oil known as alpha-linolenic acid (a-LNA), and the quality of perilla seed oil is the best.
Supercritical CO2 Extraction Equipment for Perilla Seed Oil
Perilla frutesccn seed oil has a long history of edible and medicinal appliances, which is listed as the top grade in Shennong Herbal Classic. It has the functions of protecting liver, anti-thrombosis, lowering blood lipid, lowering blood pressure, protecting eyesight, improving intelligence, and inhibiting allergic reaction and inflammation.
Supercritical CO2 Extraction of Perilla Seed Oil
We fully analyzed the characteristics of perilla seed and the drawbacks of industrial extraction of perilla seed oil. Supercritical CO2 extraction technology was combined with other technologies. The critical state was easy to achieve. There was no destructive effect on aroma components, physiological active substances, enzymes and proteins in food and medicine. Therefore, CO2 was often used as extractant for supercritical extraction.
The effective component of perilla seed oil, alpha-linolenic acid, has very strong reducibility. It can be oxidized by high temperature, oxygen in the air, ultraviolet rays and some heavy metal ions. Supercritical extraction of perilla seed oil requires a lower temperature, which avoids the destruction of the effective components under the sealed condition of CO2. Therefore, the quality and yield of the product are higher than those of traditional methods, and it is more suitable for industrial application.
Through unremitting efforts, the supercritical extraction technology has been combined with other technologies to extract perilla seed oil. The quality of perilla seed oil is high, and the oil yield is far higher than the current industrialization standards.
