Problems solved by technology

Because camellia seeds contain more oil components, it is easy to form an emulsion during the extraction process, which not only reduces the active ingredients of camellia seeds, but also increases the difficulty of subsequent extraction steps. The existence of emulsified particles also affects the stability and quality of seed oil
Camellia oil has undergone multiple treatments, which can easily cause the loss of internal active ingredients, thereby reducing the nutritional value of the finished product

Abstract

The invention provides a camellia seed extraction method. The method comprises: (1) adding water to camellia seeds to soak, filtering to remove water, adding an ethanol solution, carrying out refrigeration soaking, taking the camellia seeds, drying, and crushing to obtain a crushed material; (2) adding the ethanol solution into the crushed material, stirring, and carrying out microwave treatment to obtain a microwave treated material; (3) adding alkaline protease modified particles into the microwave treated substance, stirring, preserving heat, homogenizing, adjusting the pH value, adding a carbohydrase solution, performing enzymolysis, and filtering to obtain crude oil; and (4) squeezing and centrifuging the crude oil, and taking the obtained supernatant to obtain camellia seed oil. Through a specific preparation process, the demulsification rate and the oil yield of the camellia seed oil can be improved, the speed of generating fatty acid by fat can be delayed, the camellia seed oil has good oxidation stability, and the camellia seed extraction method is simple, easy to control and suitable for industrial mass production.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to an extraction method for camellia seeds. Background technique [0002] Camellia seed is an alias of camellia seed (scientific name Camellia seed), which is the fruit of camellia oleifera tree, which belongs to a kind of woody oil tree and is a unique woody vegetable oil resource in my country. Camellia seeds are rich in various active substances, and more active ingredients in camellia seeds can be extracted to fully improve the utilization value of camellia seed oil. Because camellia seed contains more oil components, it is easy to form an emulsion during the extraction process, which not only reduces the active ingredients of camellia seed, but also increases the difficulty of subsequent extraction steps. The existence of emulsified particles also affects the stability and quality of the seed oil. Camellia oil has undergone multiple treatments and other processes, whi...
