Abstract

Provided is a winterization method of oil-tea camellia seed oil. The method comprises the following steps that 1, oil-tea camellia seed oil is squeezed into a crystallizer for rapid precooling; 2, precooled oil-tea camellia seed oil is subjected to continuous uniform cooling, and then the temperature is kept constant; 3, the oil-tea camellia seed oil of which the temperature is constant is subjected to deep freezing, and then the temperature near the final cooling temperature is kept constant; 4, the oil-tea camellia seed oil which is subjected to freezing and constant temperature treatment is filtered through a self-flow filtering method, and the filtered oil-tea camellia seed oil is stored in warehouse after being inspected to be qualified. Compared with the prior art, according to the winterization method of the oil-tea camellia seed oil, precooling, cooling and constant temperature keeping, deep cooling and constant temperature keeping and self-flow filtering processes are adopted, the oil-tea camellia seed oil is good in crystallization effect, and crystallization is thorough, when filtering is conducted, micro crystallization and impermeable filter are achieved, therefore, turbidity of winterized oil-tea camellia seed oil is effectively prevented, the product quality is improved, cost increasing and loss which are caused by rework are reduced, product quality reduction caused by secondary winterization is avoided, and the purpose of the winterization method of the oil-tea camellia seed oil is achieved.

Description

technical field [0001] The invention relates to a winterization method, in particular to a winterization method of camellia oleifera seed oil. Background technique [0002] The existing winterization process of camellia oleifera seed oil mainly imitates the processing technology of corn oil, by continuously cooling the camellia oleifera seed oil to 5-8°C, growing crystals for a certain period of time, and then filtering and removing solid fat by means of pressure filtration. Due to the continuous freezing, in the crystallization process, because there is no constant temperature for the characteristics of the oil, most of the crystal forms are amorphous crystals, and it is difficult to filter. Corn oil cannot be completely crystallized at the temperature of the winterization process, and a lower temperature should be used to completely remove the solid fat through freezing and crystallization. This is also one of the reasons for the secondary turbidity of camellia seed oil af...
