Problems solved by technology

[0005] However, in order to improve the oil yield, the solvent leaching process needs to involve long-term immersion at high temperature, which may cause the oil to react with the solvent to form toxic substances that remain in the oil, causing harm to the human body after consumption

Embodiment 1

[0032] A method for leaching camellia oleifera seed oil utilizing high-pressure homogenization technology, comprising the following steps:

[0033] (1) Pre-treatment: Dry the freshly picked Camellia oleifera cones in the air until the camellia seed peels are cracked, remove the peels, and dry them at 85°C; store them in a low temperature environment of 4°C for 7 days, and then shell the camellia camellia seeds , making the shell content in the camellia seed kernel ≤ 0.5%, and finally crushing the camellia seed kernel through a 50-mesh sieve to obtain the crushed camellia seed;

[0034](2) Expansion: first heat the pulverized Camellia oleifera seeds to 60°C, then put them into an extruder, control the outlet thickness of the extruder to 0.25mm, and carry out extrusion and puffing treatment under the conditions of an outlet temperature of 108°C to obtain puffed After the camellia seed;

[0035] (3) Suspension preparation: add 120g of analytically pure diethylene glycol monometh...

Abstract

The invention belongs to the technical field of edible oil processing and particularly relates to a method for leaching camellia oleifera seed oil by using a high pressure homogenization technology. The technical scheme is that the method comprises the steps of pretreatment of camellia oleifera seeds, puffing of the camellia oleifera seeds, suspension mixing, high pressure blasting, low temperature crude separation, distillation for solvent removal and crude oil refining. Through the high pressure homogenization technology, the camellia oleifera seeds undergo high temperature and instant blasting treatment at 50 MPa, so that oil-containing cells are destroyed thoroughly, and oil can be quickly and fully dissolved in a leached solvent. Compared with various oil leaching technologies disclosed currently, the method can improve leaching efficiency and is low in energy consumption, the high-purity high-quality oil can be obtained, so that the cost of the camellia oleifera seed oil is reduced, and the economic benefit is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of edible oil processing, in particular to a method for extracting camellia oleifera seed oil by using high-pressure homogenization technology. 【Background technique】 [0002] Camellia oleifera, also known as tea seed tree and camellia oil tree, is a general term for perennial woody oil plants that have high oil content and yield in the Theaceae Camellia genus and are used to extract edible oil. There are more than 100 kinds of Camellia plants, and there are more than 70 kinds of Camellia oleifera trees in my country, and a certain number of them are planted in India, Vietnam, Indonesia and other countries. [0003] Camellia oil is a unique woody oil in my country. It mainly grows in the south of China, and Hunan Province is the most planted, followed by Jiangxi, Guangxi, Zhejiang and other more than ten provinces. The output of camellia oleifera seeds in my country is increasing year by year. In 2013, th...
