Embodiment 1

[0033] Adopt the following method to prepare a kind of low-temperature purification Luzhou-fragrant camellia oil:

[0034] (1) Put the camellia oil obtained after pressing fresh tea seeds into the purification tank;

[0035] (2) filtering the camellia oil obtained after the fresh camellia seed is first pressed, blowing dry with compressed nitrogen, smashing, and obtaining the filter residue;

[0036](3) Put the virgin camellia oil into the purification tank, add the filter residue, the weight ratio of filter residue to camellia oil is 2:100, adjust the stirring speed to 60 r / min, and stir evenly. The first stage: use 3°C / min The speed is gradually raised to 65°C, the purpose is to completely break the possible crystals of the camellia oil first, to prevent subsequent cooling and early crystallization, which will affect the speed of impurity removal, harm removal and filtration; the second stage: start the water cycle and freezer, at 0.5°C / The temperature is gradually lowered...

Embodiment 2

[0039] Adopt the following method to prepare a kind of low-temperature purification Luzhou-fragrant camellia oil:

[0040] (1) Put the camellia oil obtained after pressing fresh tea seeds into the purification tank;

[0041] (2) filtering the camellia oil obtained after the fresh camellia seed is first pressed, blowing dry with compressed nitrogen, smashing, and obtaining the filter residue;

[0042] (3) Put the virgin camellia oil into a purification tank, add filter residue, the weight ratio of filter residue to camellia oil is 10:100, adjust the stirring speed to 55 r / min, stir evenly, the first stage: use 5°C / min The speed is gradually raised to 65°C, the purpose is to completely break the possible crystals of camellia oil first, to prevent subsequent cooling and early crystallization, which will affect the speed of impurity removal, pest removal and filtration; the second stage: start the water cycle and freezer, at 0.8°C Gradually cool down to 20°C at a speed of 0.3°C / m...

Embodiment 3-7

[0045] The same method as in Example 1 was used to prepare Example 3-7 low-temperature purification of Luzhou-fragrant camellia oil. The difference is the addition ratio of the filter residue in the purification process of step (3). Other conditions are the same, as shown in Table 1. .

Abstract

The invention discloses a preparation method for low-temperature purification of Luzhou-fragrant camellia oil, which comprises the following process steps: taking a certain amount of the virgin camellia oil, filtering it, blowing it dry with compressed nitrogen, and crushing it to obtain filter residue; taking a certain amount of pressed camellia oil Put the camellia oil into the purification tank, add the filter residue, the weight ratio of the filter residue to the camellia oil is (2‑10): 100, stir and heat up to disperse, and then filter through programmed freezing and cooling to grow crystals and remove impurities, and obtain the low-temperature purification concentrate of the present invention. Fragrant camellia oil. The camellia oil obtained by this method has a pure and strong fragrance, a refreshing taste, just the right color and fragrance, and basically does not contain harmful ingredients such as heavy metals, pesticide residues, benzopyrene, etc., and the original active nutritional components of the camellia oil are well preserved, and the quality is better than the first grade of the national standard .

Description

technical field [0001] The invention relates to a woody vegetable oil and a preparation method thereof, in particular to a camellia oil and a preparation method thereof, in particular to a low-temperature purified strong fragrance camellia oil and a preparation method thereof. Background technique [0002] Camellia oleifera (Camellia oleifera Abe1.) is a plant of the genus Camellia in the family Theaceae, which originated in China and has a long history of cultivation. Camellia oleifera in my country is rich in resources, mainly distributed in Hunan, Jiangxi, Guangxi, Zhejiang, Fujian, Anhui, Guizhou and other provinces. According to statistics, there are currently about 4 million hectares of Camellia oleifera forests in the country, with an annual output of more than 600,000 tons of Camellia oleifera seeds. Camellia oleifera seed is the seed of camellia oleifera tree, and tea oil (also known as camellia seed oil, camellia oil, camellia oleifera oil) can be obtained by leac...
