Embodiment 1

[0015] Weigh 100 kg of dehulled tea seed kernels with 47.10% oil content and crush them to 80-100 mesh. Add 250L of water to the crushed material to adjust the slurry at a rate of 2.5:1. Stir and extract at a constant temperature of 75°C and 40r / min for 35 minutes. Centrifugal separation obtains 44.02kg of finished tea seed oil, and the calculated oil rate is:

[0016] 44.02kg / 47.10kg*100%=93.46%

Embodiment 2

[0018] Weigh 100 kg of dehulled tea seed kernels with 50.60% oil content and crush them to 80-100 mesh. Add 850L of water to the crushed material to adjust the slurry according to 8.5:1. Stir at a constant temperature at 85°C and 180r / min for 150 minutes. Centrifugal separation obtains 47.60kg of finished tea seed oil. The calculated oil rate is:

[0019] 47.60kg / 50.6kg*100%=94.07%

[0020] After testing, the main indicators of the tea seed oil obtained in Examples 1 and 2 have reached the national standard for extracting first-class finished tea seed oil; and the main nutrients in the oil are significantly higher than those of the tea seed oil prepared by conventional traditional methods. The specific data As shown in Table 1 and Table 2.

Abstract

The invention relates to a method for extracting edible oil from plant seeds, in particular to a method for extracting tea seed oil from tea seeds, the technical scheme comprises the following steps: taking shelled tea seed kernels as raw materials, grinding the shelled tea seed kernels, adding water, mixing, stirring and extracting at a constant temperature, centrifugally separating, and obtaining the finished tea seed oil with oil yield more than or equal to 93%, vitamin E content more than or equal to 47mg / 100g. The method of the invention solves the defects of low oil yield, high temperature, high voltage, residual of organic solvent and more loss of effective constituent in the extracting process of the existing tea seed oil.

Description

Technical field [0001] The invention relates to a method for extracting edible oil from plant seeds, in particular to a method for extracting tea seed oil from oil tea seeds. Background technique [0002] Camellia oleifera seed (Camellia oleifera seed), also known as camellia seed, is a woody oil peculiar to my country. The main production areas are in Jiangxi, Hunan, Anhui and southwestern provinces south of the Yangtze River. Tea seed oil is an edible vegetable oil extracted from Camellia oleifera seeds. The content of oleic acid and linoleic acid in tea seed oil is more than 90%. It also contains essential nutrients such as vitamin E and squalene. It is a high-quality oil that integrates food and health care. Therefore it is known as the "Oriental Olive Oil". [0003] But for a long time, tea seed oil extraction has been using traditional mechanical pressing tea seed, tea seed cake solvent extraction and crude oil chemical refining processing technology. Due to the high temper...
