Production method of squeezed camellia oil

Abstract

The invention relates to a production method of squeezed camellia oil. The method comprises the steps of 1), camellia fruit processing; 2), camellia seed processing; 3), camellia seed kernel processing; 4), squeezing for the first time; 5), squeezing for the second time; 6), refining. According to the method, the camellia fruit and the camellia seeds are piled and stored to make oil yield higher and oil quality better. The camellia seed kernels are frozen and pulverized before ultrasonic processing is conducted to change the internal physical structures of the seed kernels, the oil yield can be improved, and the taste of camellia oil is improved. The oil yield is maximized through squeezing for multiple times to prevent waste. Purification is finally conducted by adopting activated carbon,deodorizing processing is not needed, and natural flavors of the camellia oil is retained. According to the method, artificial intervening is started to improve the oil yield at the camellia fruit stage, an alternate cold and hot squeezing or extracting manner is adopted, no chemical additive is used, a pure physical method is adopted to efficiently retain the active ingredients of the camellia oil, the camellia oil is conformed to squeezed camellia seed oil standards of China, the natural flavors and fruit fragrance of the camellia oil are retained, the technique is simple, the cost is low,oil extraction is thorough, and the oil yield is high.

Description

technical field [0001] The invention relates to the field of processing oil products, in particular to a method for making pressed camellia oil. Background technique [0002] Camellia oil is a unique oil tree species in China. Its fruit can be used to extract important natural green organic health-care edible oil. Because of its golden or light yellow color, tea oil is pure in quality, fragrant in smell and does not contain harmful substances such as cholesterol and aflatoxin. It is widely spread that tea oil contains specific physiologically active substances tea polyphenols and camellia glycosides, which can effectively improve cardiovascular and cerebrovascular diseases, lower cholesterol and fasting blood sugar, inhibit the rise of triglycerides, and have obvious effects on inhibiting cancer cells. Effect. [0003] At present, the production of camellia oil is mainly based on pressing method and solvent method. The pressed oil has a complete color, aroma and taste, and ...

AI Technical Summary

Problems solved by technology

The tea seed oil produced by hot pressing is easy to lose the natural nutrients, active substances and inherent fragrance in the tea seed oil, and the color of the tea seed oil obtained is dark, so it must be further refined and processed, which consumes a lot of energy.

The production of tea seed oil by low-temperature pressing method is difficult for shelling and separation of shell kernels. After shelling, the oil content of tea seed kernels is high, it is difficult to pressurize, and it is easy to knot the chamber. Ordinary oil presses cannot operate normally.

Moreover, there are various sources of tea seeds, and the oil composition and active components vary greatly, resulting in problems such as low oil yield and high residual oil.
