Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0018] see figure 1 , a kind of application of microwave technology in Camellia oleifera seed processing, take a certain amount of peeled and undercoated Camellia oleifera seed kernels and carry out wet crushing, add a certain concentration of ethanol organic solvent to prepare camellia oleifera seed kernel slurry; weigh 30ml of the above-mentioned Camellia oleifera seed kernel slurry (containing ethanol 70%, solid-to-liquid ratio is 1: 7), utilizes microwave to extract tea saponin, microwave power is 300W, microwave extraction time is 30 seconds, is centrifuged under the condition of 5000rpm at rotating speed for 5 minutes, Separate the tea saponin extract and camellia seed residue, repeat the operation twice, and combine the supernatant to obtain the tea saponin extract. Microwave extraction of tea saponin has high selectivity, short time, less solvent consumpti...

Abstract

The invention relates to an application of a microwave technology in processing oil-tea camellia seeds. The microwave technology comprises the following technological steps: firstly, crushing oil-tea camellia seeds by a wet method, afterwards adopting microwaves to extract tea saponin, then adopting microwave puffing to process the residues of the oil-tea camellia seeds, and finally, carrying outsubsequent processing on the residues of the oil-tea camellia seeds. The invention directly takes the oil-tea camellia seeds as raw materials, can obtain the tea saponin with high quality, removes the tea saponin from the tea seeds firstly, is beneficial to the subsequent extraction of tea seed oil, can obtain tea oil which is nearly colorless, and can omit a decoloration procedure for refining the tea oil; the microwave extraction of the tea saponin has the advantages of high selectivity, short time consumption, little solvent consumption and high extraction rate in one time; and the microwave puffing preprocessing of the raw materials of oil-tea camellia seed kernels is beneficial to enhancing the oil yield of the subsequent preparation of the tea seed oil.

Description

【Technical field】 [0001] The invention belongs to the technical field of deep processing of agricultural and forest by-products, and relates to the application of microwave technology in the processing of camellia oleifera seeds. 【Background technique】 [0002] Camellia oleifera seed, also known as camellia seed, is one of the four major woody oil plants in the world. It is mainly distributed in China and is a unique oil resource in our country. Camellia oleifera contains two main useful components, one is tea oil and the other is tea saponin. [0003] Tea seed oil, together with olive oil, is known as the world's two largest woody edible oils, and has been known as the "treasure in oil" since ancient times. It has been confirmed by the China Center for Disease Control that the quality of camellia oil is better than that of western olive oil. Compared with olive oil, high-grade refined tea oil has higher nutrition and health care quality. Olive oil contains 75% to 90% unsa...
