Processing technology for camellia seeds

Abstract

The invention is applicable to the processing of camellia seeds, and provides a processing technology for camellia seeds. The processing technology comprises the following steps: firstly, processing harvested camellia seeds, dividing the processed camellia seeds into camellia seed kernels, shells and seed husks, performing continuous processes of one-time cold-pressing, two-time cold water elution, two-time hot water elution and one-time hot-pressing on camellia seed kernels, and respectively utilizing various products in the processes; performing two-time cold extraction and two-time hot extraction on shells and seed husks, and respectively utilizing various products in the processes. According to the invention, all the components of camellia seeds are fully utilized, and the shells and seed husks of camellia seeds, usually abandoned, are converted into products with higher economic value; grease, protein, tea saponin, tea polyphenol, tea polysaccharide and cellulose in camellia seeds are extracted respectively, a low-cost and environment-friendly extraction technology meeting the requirements of camellia seeds is designed according to the technological requirements of follow-up products, the zero contamination and zero emission of the production process are realized through the follow-up product preparation, and camellia seeds are comprehensively utilized.

Description

technical field [0001] The invention belongs to the field of biochemistry, and in particular relates to a treatment process of camellia oleifera seeds. Background technique [0002] Camellia oleifera is a woody plant of the genus Camellia endemic to southern my country and one of the world's four major sources of woody vegetable oil. Its mature seeds are rich in lipids, proteins, polysaccharides, tea polyphenols, tea saponin, multivitamins and trace elements. After the Camellia oleifera fruit is picked, the camellia oleifera seeds are obtained through ripening, drying, and shelling. The camellia oleifera husk accounts for about 60% of the fresh fruit weight, and the camellia seed is about 40%. The middle shell of the obtained camellia seed accounts for about 30% of the overall weight. Jen accounts for about 70%. Camellia oleifera husks and seed shells contain tea saponin and various active ingredients, such as tea saponin, tea polysaccharides, tea polyphenols, etc. Camellia...

AI Technical Summary

Problems solved by technology

The extraction methods mostly use organic solvents, acid-base solutions, resin adsorption or ultrafiltration. The components purified by this method are of high purity, but the cost is high and easy to pollute; there are also techniques that use water as a solvent, but the obtained components are of low purity. At the same time, because there is no follow-up supporting process to transform into suitable products, the scope of use is not wide

At present, there is no disclosure of the comprehensive utilization process of various components of camellia oleifera seeds
