Perilla oil production line

The basic production process of perilla oil: leaching method, pressing method, subcritical low temperature extraction method.

1. The difference between the leaching method and the pressing method is that the leaching method uses solvent oil to soak the oil and fat raw materials, and then extracts them at a high temperature. , Deacidification) processing, the advantages are high oil yield, low production cost, but severely destroy the nutrients in the oil during processing.

The pressing method is to separate the oil directly from the oil by physical pressure. The whole process does not involve any chemical additives. It is divided into hot pressing and cold pressing. Hot pressing requires frying the raw materials, and cold pressing requires direct processing under natural conditions. . The cold pressing method can ensure the safety and hygiene of the product, and the natural nutrition will not be destroyed. But the oil yield is low and the cost is high. Most common oils on the market are leaching oils.

　　2, subcritical low temperature extraction method. The method is to process perilla in a closed system at no higher than 40 degrees, and retain the nutrients of perilla oil. In addition to the advantages of the cold pressing method, it also has a high oil yield, which can be used for large-scale industrial production and reduce resource waste.

　　 The ratio of ω-3 series (α-linolenic acid) and ω-6 series (γ-linolenic acid) in unsaturated fatty acids in perilla oil is close to (4-6):1. Perilla oil contains 18 kinds of amino acids, among which the amino acids whose content exceeds 5% of protein content are from more to less, followed by glutamic acid (26.3%), aspartic acid (12.5%), arginine (11.8%), and glycine (7%), Leucine (6.8%), Tryptophan (5.8%), Alanine (5.4%), Phenylalanine (5.3%), Isoleucine (5.2%).
