Problems solved by technology

[0003] In addition, the current camellia oil pressing production process can produce and retain some natural flavor substances of camellia oil, but various treatments under high temperature conditions tend to produce highly toxic benzopyrene, resulting in the content of benzopyrene in camellia oil exceeding National edible oil hygienic standards, causing food safety problems

Embodiment 1

[0013] A method for squeezing camellia oil, comprising the following steps:

[0014] The first step is to use manual picking and select high-quality tea fruits; specifically, fresh and mature camellia oleifera fruits can be selected from the organic wild camellia oleifera base of the year;

[0015] The second step is to air-dry or air-dry the tea fruit naturally, so that the water content is controlled at 9%; shelling, separating the kernel and shell, and obtaining the camellia oleifera seed kernel;

[0016] The third step is to press the above-mentioned camellia seed kernels into an oil press, the temperature of the seeds entering is the ambient temperature, and the temperature of the pressing chamber and the squeezed oil is controlled to be lower than 65°C, to obtain virgin camellia oil and camellia seed;

[0017] The fourth step is to put the virgin camellia oil into a freezing container, and freeze and cool down according to the following two-stage procedure: the first sta...

Embodiment 2

[0021] A method for squeezing camellia oil, comprising the following steps:

[0022] The first step is to use manual picking to select high-quality tea fruit;

[0023] The second step is to dry the tea fruit in the sun or air-dry to keep the water content at 10%; shell it to separate the kernel and shell to obtain the camellia oleifera seed kernel;

[0024] The third step is to press the above-mentioned camellia seed kernels into an oil press, the temperature of the seeds entering is the ambient temperature, and the temperature of the pressing chamber and the squeezed oil is controlled to be lower than 65°C, to obtain virgin camellia oil and camellia seed;

[0025] The fourth step is to put the virgin camellia oil into a freezing container, and freeze and lower the temperature according to the following two-stage procedure: the first stage, stirring at a rotating speed of 60r / min for 35min, and cooling to 65°C; the second stage, Stir at a rotational speed of 8r / min, and cool ...

Embodiment 3

[0029] A method for squeezing camellia oil, comprising the following steps:

[0030] The first step is to use manual picking to select high-quality tea fruits;

[0031] The second step is to dry the tea fruit in the sun or air-dry naturally, so that the water content is controlled at 11%; shelling, separating the kernel and shell, and obtaining the camellia oleifera seed kernel;

[0032] The third step is to press the above-mentioned camellia seed kernels into an oil press, the temperature of the seeds entering is the ambient temperature, and the temperature of the pressing chamber and the squeezed oil is controlled to be lower than 65°C, to obtain virgin camellia oil and camellia seed;

[0033] The fourth step is to put the virgin camellia oil into a freezing container, and freeze and lower the temperature according to the following two-stage procedure: the first stage, stirring at a speed of 65r / min for 40min, and cooling to 70°C; the second stage, Stir at a rotational spee...

Abstract

The invention relates to the technical field of a plant oil squeezing method and concretely relates to a camellia oil squeezing method. The camellia oil squeezing method comprises 1, carefully selecting high-quality camellia fruits by manual picking, 2, carrying out natural airing in the sun or air drying on the camellia fruits so that water content is controlled in a range of 9-11%, and carrying out unshelling so that kernels and shells are separated and camellia seed kernels are obtained, and 3, squeezing the camellia seed kernels by an oil press, wherein a seed feeding temperature is an environment temperature. Fresh and high-quality camellia fruits are selected, then are subjected to natural airing in the sun or air drying and then are subjected to unshelling so that camellia seed kernels are obtained and the camellia seed kernels are squeezed by cold squeezing so that the camellia oil is obtained. The camellia oil squeezing method does not destroy a camellia oil nutrition value. Compared with the traditional oil squeezing method, the camellia oil squeezing method is free of a chemical reagent or a chemical auxiliary agent. The camellia oil has a pure fragrance, a refreshing taste and appropriate fragrance, color and taste, does not contain harmful components such as heavy metals, pesticide residues and benzopyrene, has zero trans-fatty acid content and well retains original active nutrition components of camellia oil.

Description

technical field [0001] The invention relates to the technical field of plant oil extraction methods, in particular to a camellia oil extraction method. Background technique [0002] Camellia oleifera is a unique oil resource in my country. Due to the lack of resources in foreign countries, there is very little processing and development. At present, the processing of camellia oleifera in our country is still "rough and primitive", and the traditional processing method is mostly used now. The scale is small and the technology is backward. When the camellia oleifera seeds are processed at high temperature for a long time, not only the yield of oil is low, but the quality of oil is poor. The color is deep, and the processing energy consumption is high, the cost is high, and it will also lead to the destruction of the structure of by-products in camellia oleifera seeds such as tea saponin, polysaccharides, and trace nutrients, and the loss of biological activity. Studies have s...
