Camellia oleifera fruit phase separation process

Abstract

A camellia oleifera fruit phase separation process comprises: (1) selection, which includes selecting newly-picked fresh plump camellia oleifera fruits; (2) hulling, which includes hulling the camellia oleifera fruits to obtain fresh plump camellia oleifera seeds; (3) washing, which includes washing the camellia oleifera seeds obtained from the step (2) with water; (4) pulverization, which includes putting the camellia oleifera seeds obtained from the step (3) to a pulverizer to obtain camellia oleifera seed granules; (5) phase separation 1, which includes putting the camellia oleifera seed granules obtained from the step (4) to a juice extractor, and performing extruding to obtain solid fiber powder and liquid whey; (6) medium separation, which includes sending the whey obtained from the step (5) to a reaction pot, performing heating, adding a medium, and performing continuous stirring and heating for layering; (7) phase separation 2, which includes centrifuging the emulsion obtained from step (6) to obtain light-phase camellia oil, a heavy-phase tea saponin solution, solid-phase protein, and a starch mixture; and (8) cold extraction. The process is simple in steps and high in oil yield, allows a lot of nutrients to be kept, and fully utilizes the camellia oleifera fruits.

Description

technical field [0001] The invention relates to the processing of oilseed fruit, in particular to a process method of phase separation of camellia oleifera fruit. Background technique [0002] Camellia oleifera is a plant of the genus Camellia in the family Theaceae. Camellia oleifera seed is the seed of the camellia oleifera tree. Camellia oil (also known as camellia seed oil, camellia oil, camellia oleifera oil) can be obtained by leaching or pressing. Camellia oil is a healthy and delicious edible oil. It is not only good in color, fragrance and taste, but also has the effect of preventing cardiovascular diseases such as hypertension, coronary heart disease and atherosclerosis, and has important development and utilization value. [0003] At present, the production methods of camellia oil mainly include pressing method, solvent leaching method, aqueous enzymatic method, supercritical fluid extraction method and so on. Among them, the pressing method, solvent leaching met...

AI Technical Summary

Problems solved by technology

Among them, the pressing method, solvent leaching method and supercritical fluid extraction method have high requirements on the moisture of the oil raw material. When the moisture is low to a certain range, the oil yield of the oil can reach a high level; the aqueous enzymatic method is to fine the oil raw material and add water to adjust the pH Then add biological enzymes to extract the oil under certain conditions. The oil raw materials are crushed as finely as possible, and the moisture requirements of the oil raw materials are also high; and people control the moisture of the oil raw materials through natural drying and then mechanical drying. The moisture control process requires a long period; fresh tea fruit leaves the parent body after picking, and internal consumption of nutrients occurs, and the oil quality decreases during the moisture control process, and subsequent degumming, deacidification, decolorization, deodorization and winterization of oil may be required Refining, which not only causes a decrease in nutritional value, but also creates more or less potential safety hazards
