Description

A kind of processing technology of camellia oleifera seed

technical field

The invention belongs to the field of biochemistry, and in particular relates to a treatment process of camellia oleifera seeds.

Background technique

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 oleifera nuts mainly contain oil components, which are the main economic ingredients. Camellia oleifera husks and seed husks account for most of the harvested camellia oleifera fruit. Because oil cannot be squeezed, it contains a variety of plant acids such as grass seeds, and the content of tea saponin, tea polysaccharides, tea polyphenols and protein is lower than that of nuts, so it is not easy to purify. Economical, often discarded. The main component of camellia oil produced through the processing technology is glyceride rich in oleic acid, contains a variety of sterols and vitamins, does not contain cholesterol, and has no pesticide residues. It is a real pure natural organic edible oil and high-grade cosmetic oil; its pressed oil The main components of the remaining tea meal are protein, polysaccharides, tea polyphenols and tea saponin, which can also be further comprehensively utilized, but there is no comprehensive utilization process for tea meal at present.

At present, the most important use of Camellia oleifera seeds is oil extraction. The most common method of oil extraction is the screw pressing method with temperature controlled at 130-180°C. This method has lower temperature control, higher oil yield and better oil quality; There is also an organic solvent extraction method. This method has a high oil yield but the oil quality is not high, the flavor is not good, and it is easy to remain and mix harmful substances; in order to obtain higher quality camellia oil, retain more abundant camellia oil Active ingredients, high-quality camellia oil is also obtained by cold pressing, but the oil yield is very low, and there is no special camellia fragrance; there is also high-quality camellia oil obtained by _CO2 critical extraction, which has a high oil yield and no harmful substances residual, but the production cost is too high, and there is no special tea oil fragrance.

The tea meal left after the production of tea oil is mainly used to extract tea saponin, tea polysaccharide and flower seed protein. 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 convert into a suitable product, the scope of use is not wide. At present, there is no disclosure of a comprehensive utilization process for various components of camellia oleifera seeds.

Therefore, under the premise of emphasizing the control of environmental protection in the process, the pretreated camellia seeds are subjected to one cold pressing, three cold extractions, two hot extractions, one hot pressing, and saponification of the remaining fat. After this process, two kinds of camellia oil, tea saponin solution, tea polysaccharide, tea polyphenol and protein solution, the remaining lipid and cellulose mixture, and the precipitate and oil-containing waste after purification of camellia oil are finally obtained. . Edible tea oil with different flavors and nutrients can be obtained through the modulation of two kinds of tea oil obtained successively; cold-pressed tea oil and tea saponin can be used to prepare high-grade skin care products; tea oil can also be used as a base to add a variety of active ingredients to become functional Tea oil health care products; tea polysaccharides, tea polyphenols, tea seed protein and multivitamins extracted from the elution can be made into a variety of nutrition and health care products; oily waste generated during the production process and cellulose and lipid mixture soap left over from the extraction process Modulated with tea saponin, and finally become a series of washing products.

The invention converts often discarded Camellia oleifera husks and seed husks into products with high economic value, and converts oil-containing waste materials produced in the general camellia oil purification process, such as cold-pressed and hot-pressed precipitates obtained by cold storage, into camellia oleifera Raw materials for health care products, oil-containing activated clay and activated carbon produced during the purification process of camellia oleifera become raw materials for washing products after saponification. The mixture containing tea polyphenols, alkaloids, polysaccharides and proteins obtained through multiple steps can preserve the active substances to the greatest extent through vacuum freeze-drying, and can become an important raw material for Camellia oleifera health products and functional medicines; Due to the cold extraction process in the early stage, the liquid contains less impurities and high concentration, and can be directly used in the development of later washing products or skin care products; through the subsequent product preparation, the whole process has realized no waste liquid and waste discharge, which is a good choice for Camellia oleifera A comprehensive treatment process for comprehensive utilization of seeds.

In the process of the present invention, two parts of camellia oil, cold pressing and hot pressing, will be obtained respectively, each has its own characteristics, and can be used as raw materials for various products in subsequent processes, such as high-grade skin care products, tea oil health products, edible oil, functional Camellia oil products, etc.; and the solid product left after the tea oil is refrigerated and purified is rich in lecithin, protein, polysaccharide, multivitamins and trace elements, and becomes the raw material of health care products; and the activated clay produced during the purification process can be used as soap The raw material of camellia oil cleaning products, and the cleaning products made of fat-containing activated carbon saponification can cover other raw materials of any color.

In the hot pressing process, the bottom material that has been pulverized and purified in the early stage is used, so the improved hot pressing machine in the hot pressing process realizes the direct deodorization during the pressing process through a longer heating pressing channel and a steam release valve. process; the workload of subsequent degumming and gum acid steps has also been greatly reduced; the remaining materials of each step including dehydration of camellia oil can enter the subsequent KOH saponification and become raw materials for washing products.

Ultrasonic-assisted cold water and hot water extraction are used in the production process, with low cost and no pollution; the cold extraction process well preserves various active ingredients of camellia oleifera seeds, and at the same time greatly reduces the starch and fruit content of tea leaves after cold pressing. The content of gum, soluble protein and other glycogen improves the product purity of the subsequent extraction steps; the thermal extraction process maximizes the extraction of relatively high-purity tea saponin, which becomes an important raw material for washing products, and thus directly becomes the raw material for later washing products , to prevent waste water discharge.

The final solid residue of tea meal is mainly cellulose and lipids. The present invention uses cellulase to improve the structure of cellulose and is more suitable for washing products. It has a moderate massage effect on the skin during use. Good for exfoliating hyperkeratinized parts of the skin surface.
