Abstract

The invention belongs to the technical field of protein extraction, and particularly relates to an extraction method of oil-tea cake protein and application of the oil-tea cake protein. The extraction method comprises the following steps: (1) pretreatment: adding acetone into oil tea cakes, quickly and uniformly stirring at low temperature, filtering, and flushing with trimethylsilyl ether to obtain a primary pretreated material; (2) secondary pretreatment: adding immobilized enzyme and a protein stabilizer into the primary treated material, and performing enzymolysis treatment to obtain a secondary pretreated material; (3) differential pressure extraction: adding the secondary pretreated material into a buffer solution, performing differential pressure extraction, and filtering to obtain an extracting solution; and (4) concentrating and drying, namely adjusting the pH value of the extracting solution, standing to generate a precipitate, and freeze-drying the obtained precipitate to obtain the oil-tea cake protein. The extraction method of the oil-tea cake protein provided by the invention is high in oil-tea cake protein extraction rate, low in protein active group destructiveness and high in cross-linking reaction activity, and can be used for preparing a wood adhesive.

Description

technical field [0001] The invention belongs to the technical field of protein extraction, in particular to a method for extracting camellia cake protein and the application of the camellia cake protein. Background technique [0002] Camellia oleifera cake is the main by-product in the process of extracting camellia oil from Camellia oleifera fruit. Camellia cake is rich in protein, carbohydrates, saponins, etc. Correlation analysis shows that Camellia cake contains 19% to 25% crude protein, 35% to 40% sugar, 5% crude fat, 6% crude Fiber, 10% to 15% saponin. Camellia meal contains high crude protein, which is a good protein resource with development potential. [0003] At present, the extraction and application research of camellia cake protein is mainly concentrated in the food field. The extracted camellia cake protein has strong emulsification and oil absorption, and is used in ice cream, bakery products, meat products, imitation meat products and protein drinks. , The...
