Abstract

The invention discloses a production and processing method for edible camellia seed oil with low acid value and high quality. The production and processing method comprises multistage separation supercritical CO2 extraction and molecular distillation refining. According to the invention, through multistage separation supercritical CO2 extraction for camellia seed oil, high extraction rate is maintained; due to multistage separation, simultaneous separation of water, free fatty acid, odor components, pigment components and the like can be realized; and through refining treatment with a molecular distillation technology, the edible camellia seed oil with low acid value and high quality is obtained, and the edible camellia seed oil can reach an oil yield of 90% or above, an acid value of lessthan 0.6 and an unsaturated fatty acid content of 90% or above, and is rich in natural anti-oxidant active components like vitamin E, squalene and beta-sitosterol. The production and processing method provided by the invention avoids traditional technical processes of degumming, deacidifying, decolorizing, dewaxing and deodorizing, and has the advantages of high oil yield, short life cycle, avoidance of product oxidation and rancidification, retention of nutrient components in oil, no flammable and explosive hazards, no environmental pollution, no solvent and heavy metal residues, natural quality ensurance of camellia oil, etc.

Description

technical field [0001] The invention relates to the technical field of edible oil preparation, in particular to a method for producing and processing edible camellia oleifera seed oil with low acid value and high quality. Background technique [0002] Camellia oleifera (Camellia oleifera Abel.) is a unique woody oil tree species in my country. Camellia oleifera seed oil is refined from camellia oleifera seeds. It is rich in unsaturated fatty acids, glycerides and various vitamins and other nutrients. Camellia oleifera seed oil is not only beautiful in color, fragrance, but also because its fatty acid composition is very similar to that of olive oil, a world-recognized high-quality oil, and its unsaturated fatty acid content is higher than that of olive oil, and its "smoke point" is high. It is an ideal high-nutrition, Low-calorie, high-grade health edible oil. In recent years, the International Food and Agriculture Organization has listed camellia seed oil as a healthy edib...
