Problems solved by technology

In actual production, it was found that under high temperature and high pressure, the excessive refining of tea seed oil lost a large amount of oil-soluble substances, and active ingredients such as tocopherol, DHA, squalene, etc. were also easily oxidized or taken away by steam, making these precious natural oils Active substances are wasted

Embodiment approach

[0031] A preparation method of Camellia oleifera seed oil solid powder rich in squalene and DHA, comprising the steps of:

[0032] 1. Obtaining crude oil

[0033] Camellia oleifera seeds are pressed at low temperature to obtain squeezed oil, and the squeezed oil is filtered to obtain crude oil of camellia oleifera seeds with an impurity content of less than 0.2 wt%.

[0034] 2. Refining

[0035] (1) Degumming: Degumming: Slowly add 10 parts by weight of warm water (water temperature is 35±5°C) to 100 parts by weight of tea seed crude oil, stir while adding warm water, keep stirring for 10 to 15 minutes, and then let it stand for 3 to 5 minutes After 4 hours, settling and separating, removing the impurities and water in the lower layer to obtain primary degummed oil; slowly add 5 parts by weight of warm water to 100 parts by weight of primary degummed oil, stir while adding warm water, continue stirring for 10 to 15 minutes, and then let it stand After 3 to 4 hours, settle an...

Embodiment 1

[0041] Camellia seed oil degumming

[0042] Crude oil was obtained by low-temperature pressing of Camellia oleifera seeds picked in the same year, and the tested crude oil was divided into two groups. The first group of crude oil is degummed by the traditional method: slowly add 15 parts by weight of warm water at a temperature of 35°C to 100 parts by weight of crude oil, stir while adding water, keep stirring for 12 minutes, then stand for 3.5 hours, and use sedimentation after standing After the separation method removes the impurities and water in the lower layer, the degummed oil is obtained. The second group of crude oil uses the degumming process of the present invention, and its process parameters are: slowly add 10 parts by weight of warm water at a temperature of 35°C to 100 parts by weight of tea seed crude oil, stir while adding warm water, continue to stir for 12 minutes, and then statically Settled and separated for 3.5 hours, removed the lower layer of impuritie...

Embodiment 2

[0046] Camellia seed oil deacidification

[0047] Use the second group of degummed tea seed oil in Example 1 as the deacidification material, and the first group of degummed oil is deacidified by the traditional method. The process parameters are: use 100 parts by weight of degummed oil, heat the degummed oil to 45 ° C, add 3 parts by weight of sodium hydroxide solution with a concentration of 12%, stirred for 30 minutes to neutralize the free acid in camellia oleifera oil; then 15 parts by weight of water at 80°C were added to the mixture, stirred and washed and left to stand for 4 hours, separated by sedimentation Remove water and soapstock to obtain deacidified oil. The second group of degummed oils adopts an excess alkali deacidification process (technique of the present invention): with 100 parts by weight of degummed oils, heated to 45 ° C, adding 2 parts by weight of a concentration of 10% sodium hydroxide solution, stirred for 30 minutes ; Then add 15 parts by weight ...

Abstract

The invention discloses a preparation method of a camellia tea seed oil solid powder rich in squalene and DHA. The method mainly comprises the two steps of crude oil obtaining and crude oil refining,and refining parameters of refining processes are changed, especially a deodorizing process is reduced and a one-time degumming process is arranged, according to the characteristics of the oil tea seed oil and the physical and chemical properties of DHA and squalene, so impurities and some undesirable components in the camellia seed oil are effectively removed, and DHA and squalene in the oil teaseed oil are reserved maximally. The product oil can be further solidified to protect the solidified oil from being affected by the environment, so the product has the characteristics of improved stability, easiness in carrying and transporting, and convenience in use.

Description

technical field [0001] The invention relates to the technical field of camellia oleifera seed oil production, in particular to a camellia oleifera seed oil powder rich in squalene and DHA. Background technique [0002] Camellia ( Camellia oleifera Abel ) originated in China, and has been cultivated and utilized for more than 2300 years. It is a woody oil crop that grows in the southern hilly areas. According to statistics, the total annual output of camellia oleifera seeds in my country is more than 600,000 tons, and the annual output of camellia oleifera seed oil is 150,000 tons. Among them, Hunan and Jiangxi provinces have the largest output, accounting for more than 60% of the total national camellia seed output. Camellia oleifera seed oil is a green, ecological and high-nutrition health-care edible oil. It is a treasure among edible oils and can be called "Oriental olive oil". The reason why camellia oil is known as "Oriental olive oil" is mainly because its fatty acid...
