Problems solved by technology

However, the existing methods for producing gamma-linolenic acid are nothing more than plant extraction and biological fermentation. Regardless of the different extraction processes and equipment, the pure content of the extracted gamma-linolenic acid does not exceed 15%, and the extraction method is cumbersome. Requires complex process and high equipment requirements

Embodiment 1

[0033] Take 10 kg of Simao pine nuts, 60 kg of Yunnan pine nuts (PinusyunnansnsisFranch), and 10 kg of oil sunflower seeds according to the weight ratio. , then add 10 kg of walnut kernels and dry them together at a temperature of 100-130 ° C. After compacting and pressing repeatedly with an oil press, crude oil is obtained and placed for later use; another 10 kg of lotus seeds are soaked and ground into a slurry, and mixed with the above Crude oil is mixed, and the mixture is filtered with a plate and frame filter press or a box filter press to remove impurities, and then use high-concentration soda ash to deacidify the crude oil according to the acid value of the crude oil, and then use hot alkaline water at 70°C to precipitate and discharge the soapstock , to detect the acid value, if further deacidification is required, carry out the second deacidification, the temperature of the water and oil in the second deacidification is about 60°C, and then discharge the soapstock, an...

Embodiment 2

[0036]First take 20 catties of Simao pine nuts, 70 kg of Yunnan pine nuts (Pinusyunnanensis Franch), and 15 kg of oil sunflower seeds according to the weight ratio. Then add 20 kg of walnut kernels and dry them together at a temperature of 100-130°C. After compacting and pressing repeatedly with an oil press, crude oil is obtained and placed for later use; another 10 kg of lotus kernels are soaked and ground into a pulp, and mixed with The above crude oil is mixed, and the mixture is filtered with a plate and frame filter press or a box filter press to remove impurities, and then use high-concentration soda ash to deacidify the crude oil according to the acid value of the crude oil, and then use hot alkaline water at 70°C to precipitate and discharge the soap If it is necessary to deacidify again, then carry out secondary deacidification. The water and oil temperature of the secondary deacidification are all around 60°C, and then the soapstock is discharged to finally make the aci...

Embodiment 3

[0039] First take 15 kg of Simao pine nuts, 50 kg of Yunnan pine nuts (Pinusyunnanersis Franch), and 10 kg of oil sunflower seeds according to the weight ratio. Then add 15 kg of walnut kernels and dry them together at a temperature of 100-130°C. After compacting and pressing repeatedly with an oil press, crude oil is obtained and placed for later use; another 5 kg of lotus kernels are soaked and ground into pulp, and mixed with The above crude oil is mixed, and the mixture is filtered with a plate and frame filter press or a box filter press to remove impurities, and then use high-concentration soda ash to deacidify the crude oil according to the acid value of the crude oil, and then use hot alkaline water at 70°C to precipitate and discharge the soap If it is necessary to deacidify again, then carry out secondary deacidification. The water and oil temperature of the secondary deacidification are all around 60°C, and then the soapstock is discharged to finally make the acid va...

Abstract

The invention relates to edible oil and a preparation method thereof. The edible oil comprises 5-20 parts of walnut kernels, 5-20 parts of pinus kesiya seeds, 40-70 parts of pinus yunnanensis seeds, 5-20 parts of oil sunflower seeds and 5-10 parts of lotus seed kernels. The preparation method is characterized by comprising the following steps of separately taking the pinus kesiya seeds, the pinus yunnanensis seeds and the oil sunflower seeds firstly; through screening, pneumatic separation and flotation, removing impurities, earth and stone, fine sand, dust, vacant shells and tails; then adding the walnut kernels, jointly drying the processed pinus kesiya seeds, the processed pinus yunnanensis seeds, the processed oil sunflower seeds and the walnut kernels at the temperature of 100-130 DEG C, and through repeated extraction of a green compact and an oil press, obtaining crude oil which is put for standby application; additionally taking the lotus seed kernels, soaking the lotus seed kernels, grinding the soaked lotus seed kernels to obtain pulp, mixing the pulp and the crude oil so as to obtain a mixture; filtering the mixture so as to filter off impurities; deacidifying the filtered mixture with hot alkaline water of 70 DEG C made of high-concentration sodium carbonate so that the acid value reaches 0.8-1.5%; adding hot water of 70 DEG C, repeatedly washing the deacidified mixture, and maintaining oil temperature to be 80-90 DEG C; after the mixture is stirred and washed each time, precipitating the mixture for 2 hours, draining the precipitated mixture, then washing the drained mixture, and finally through vacuum dewatering, basically draining waste water caused by washing so as to obtain oil foods.

Description

technical field [0001] The present invention relates to a kind of edible oil, more specifically, the present invention relates to a kind of edible oil that is made by the mixed extract of walnut kernel, Simao pine nut, Yunnan pine nut, oil sunflower seed, lotus seed kernel, meanwhile, the present invention also The invention relates to a preparation method of the edible oil. Background technique [0002] Since the pharmacology pioneer first discovered and named γ-linolenic acid from evening primrose, γ-linolenic acid and its series of metabolites have important and extensive physiological effects in the immune system, cardiovascular system, reproductive system, and endocrine system Therefore, many scholars from various countries have done a lot of research and experimental work on its structure, pharmacology, toxicology and development and application, and found that there are many plants containing γ-linolenic acid, such as evening primrose, Heijiazizi, Shanhaidan , borage...
