Problems solved by technology

People who are accustomed to eating camellia oil can accept this unique taste, if there is no such special disadvantage: due to the special taste, it is not suitable for most people who have never eaten or rarely eat camellia oil
Since the entire pressing process (physical pressing) is mainly manual, the labor cost is high and the efficiency is relatively low, and the oil yield is also low

Embodiment 1

[0018] The process of low temperature cold pressing oil production is as follows:

[0019] Camellia oleifera seeds→cleaning and removing impurities→hulling and shell kernel separation→cold pressing→cold pressing crude oil→coarse filtration→cleaning filtration→refining (dephosphorization, desulfurization, degumming, deacidification, dehydration, decolorization, deodorization, etc.)→high-quality tea Oil. The oil yield of Camellia oleifera seeds reached 19.8%. The pressing conditions are as follows: low-temperature press, pressing temperature 38°C, rotating speed 30r / min, pressing chamber pressure 3.5Mpa. After pressing, the crude oil is collected and processed by filtration, further decolorization and other refining processes.

Embodiment 2

[0021] Low-temperature cold pressing oil production process: After removing impurities, the camellia seeds are shelled and the shells are separated. After the camellia seeds are sprayed with 4% salt water, they are frozen at -25°C for 40 minutes and crushed. The crushed camellia seeds are subjected to the second The oil is pressed once, and the pressing conditions are as follows: low-temperature press, pressing temperature 35°C, rotating speed 30r / min, pressing chamber pressure 3.5Mpa. After pressing, 10% of the mass of Camellia oleifera seed kernels is added to the material and mixed, and then pressed. The pressing conditions are: twin-screw oil press, the pressing temperature is 30°C, and the crude oil is collected after pressing, filtered and further decolorized, etc. Refined process treatment. The acid value of the product of the present invention is 0.02mgKOH / g, and the peroxide value: 0.3mmol / kg. Freezing experiment treatment, kept at -8°C for 12 hours and still remaine...

Embodiment 3

[0023] Process method: After the camellia seed is removed from impurities, it is shelled and the shell kernel is separated. After the camellia seed kernel is sprayed with 5% salt water, it is frozen at -25°C for 50 minutes and crushed, and the crushed camellia seed kernel is pressed for the first time. Oil, the pressing conditions are as follows: low-temperature press, pressing temperature 40°C, rotating speed 30r / min, pressing chamber pressure 3.5Mpa. After pressing, 5% of the mass of Camellia oleifera seed kernels is added to the material and mixed, and then pressed. The pressing conditions are: twin-screw oil press, the pressing temperature is 25°C, and the crude oil is collected after pressing, filtered and further decolorized, etc. Refined process treatment. The acid value of the product of the present invention is 0.03mgKOH / g, and the peroxide value: 0.4mmol / kg. Freezing experiment treatment, kept at -8°C for 12 hours and still remained clear and transparent. Camellia ...

Abstract

The invention discloses a camellia seed cold pressing oil making process. The camellia seed cold pressing oil making process includes the following steps of camellia seed taking, cleaning and impurity removing, deshelling and shell and kernel separating, cold pressing, crude oil cold pressing, coarse filtering, clear filtering, refining and high-quality camellia oil obtaining. The acid value of a product is 0.03 mgKOH / g, and the peroxidation value of the product is 0.3-1 mmol / kg. Through treatment of a freezing test, the product is still kept in a clear and transparent state after being kept for 10 hours at the temperature of -8 DEG C.

Description

technical field [0001] The invention belongs to the field of food processing. Background technique [0002] Camellia oleifera seed oil, also known as wild camellia oil, is a pure natural high-grade woody edible oil. Camellia oleifera grows in the subtropical Nanling humid climate zone, and the whole growth process does not require auxiliary means such as chemical fertilizers and pesticides. The growth period of camellia fruit is from flowering to maturity. It has experienced the rain and dew in autumn, winter, spring, summer and autumn. It absorbs natural nutrients and the essence of the sun and the moon, and its nutritional value is extremely high. It is the edible vegetable oil strongly advocated and promoted in the "Outline of China's Food Structure Reform and Development Plan", and it is also the health care vegetable edible oil first recommended by the International Food and Agriculture Organization. Camellia oleifera seed oil is derived from the mature seeds of Camel...
