Abstract

The invention discloses a method for multi-level value-added utilization of camellia oleifera shells. The method comprises the following steps: firstly, crushing the camellia oleifera shells and screening by a 60-mesh sieve; obtaining tea saponins and tannins from the camellia oleifera shells by an ultrasonic-microwave synergistic stepwise extraction process; inoculating edible fungi after addinga small amount of brans into primary waste residues; raising the temperature and adding lysozyme to promote autolysis of edible fungal hyphae after the fungi grow all over a substrate; releasing cellulase and hemicellulase to obtain prebiotics rich in oligomeric cellulosic polysaccharide, oligomeric pentose and peptidoglycan; preparing secondary camellia oleifera shell waste residues with a high lignin content into an aromatic compound by a low-temperature microwave catalysis rapid-cracking technology; using the aromatic compound after separation and purification as a precursor for producing edible essence; and using residual biochar after steam activation for activated carbon for food industry. The method provided by the invention combines three major industries of edible camellia oleifera oil processing, food additive and biomass refining, proposes a new process of multi-level value-added utilization of the camellia oleifera shells, and can finally realize a new way of efficient value-added utilization of camellia oleifera shell resources without wastes in a whole process.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of food waste, and relates to a method for preparing tea saponin, tannin, prebiotics, aromatic compounds and activated carbon for food industry decolorization through camellia oleifera shells. Background technique [0002] Camellia oleifera is an important woody oil crop in my country. It can produce 5.6 million tons of camellia oleifera fruit per year. As a by-product of camellia oil refinery, the annual output of camellia oleifera shell is as high as 3 million tons. It has not been effectively used as a by-product of agricultural processing for a long time. use. [0003] Tea saponin has various surface activities such as emulsification, dispersion, wetting, and foaming. It is an excellent natural phosphorus-free nonionic surfactant and is widely used in chemical, food, and pharmaceutical fields. Relevant studies have shown that the content of tea saponin in camellia oleifera husk ac...
