Technology for squeezing cold-drawn camellia oil

Abstract

The invention discloses a technology for squeezing cold-drawn camellia oil. The technology includes steps of 1), crushing and shelling camellia, 2), cooking the camellia; 3), squeezing the camellia to obtain crude oil; 4) filtering the crude oil. The technology for squeezing the cold-drawn camellia oil has the advantages that the traditional technologies for preparing camellia oil by the aid of hot-squeezing methods and solvent-extraction methods are changed, accordingly, the camellia oil has light colors, clean and pure smell and fragrant taste and is safe and perfect in quality; problems of pollutant hazards and nutritional component loss in high-temperature squeezing procedures or chemical pollution and nutritional loss in procedures implemented by the aid of extraction methods can be solved.

Description

technical field [0001] The invention specifically relates to a pressing process of cold-pressed camellia oil. Background technique [0002] Camellia oleifera seed oil can be divided into different production processes: pressing method, solvent extraction method, aqueous enzymatic method, supercritical carbon dioxide extraction method and water substitution method, etc. Due to the limitation of process technology, the water substitution method cannot be applied on a large scale at present. [0003] In industrial production, other processes have been applied in the production process of Camellia oleifera seed oil. But the main production process of domestic Camellia oleifera seed oil is still limited to the first two. Usually, those processed with Camellia oleifera seeds as raw materials are generally prepared by pressing method, and those processed with Camellia oleifera meal or Camellia oleifera cake as raw materials are usually prepared by solvent extraction. Because the...

Problems solved by technology

Because the traditional oil extraction method cannot effectively separate the mildewed tea seeds from the raw materials, and the material embryos must be fried at high temperature during the production process, it is easy to lose the nutritional components, active substances and inherent fragrance of camellia oleifera seed oil , the crude oil will contain benzo[a]pyrene to varying degrees. In recent years, with the in-depth research on the quality and safety of camellia oleifera seed oil, cold-pressed camellia oleifera seed oil has become a kind of processing technology for camellia oleifera seed oil in major tea-producing areas in China. development trend
