Embodiment 1

[0035] (1) Take the radix radix radix seed kernels, freeze-dry them at low temperature in vacuum, and then use a sesame oil refiner (adjust the thickness of the disc of the refiner to pass 40 meshes) to refine the pulp to obtain the radix radix radix seed pulp, and refrigerate it for later use;

[0036] (2) Accurately weigh 20g of radix sorbifolium seed pulp, dissolve it with 40ml of sodium chloride aqueous solution with a concentration of 17g / L, and place it in an ultrasonic extractor for extraction: adjust the ultrasonic power to 60KH Z , The stirring speed is 40r / min, the temperature is 50°C, and the extraction time is 60min;

[0037] (3) Centrifuge the extract with a high-speed centrifuge: the centrifugation temperature is 20°C, the centrifugation speed is 7000r / min, and the centrifugation time is 10min; after centrifugation, the upper layer is taken out, which is the pure natural Xantho sorbifolia seed oil. The extraction rate is 63.48%.

Embodiment 2

[0039] (1) Take the radix radix radix seed kernels, freeze-dry them at low temperature in vacuum, and then use a sesame oil refiner (adjust the thickness of the disc of the refiner to pass 40 meshes) to refine the pulp to obtain the radix radix radix seed pulp, and refrigerate it for later use;

[0040] (2) Accurately weigh 20g of sorbifolia seed pulp, dissolve it with 60ml of 33g / L sodium chloride aqueous solution, and place it in an ultrasonic extractor for extraction: adjust the ultrasonic power to 70KH Z , the stirring speed is 50r / min, the temperature is 55°C, and the extraction time is 90min;

[0041] (3) Centrifuge the extract with a high-speed centrifuge: the centrifugation temperature is 25°C, the centrifugation speed is 8000r / min, and the centrifugation time is 15min; after centrifugation, the upper layer is taken out to be the pure natural Xanthania sorbifolia seed oil. The extraction rate is 68.79%.

Embodiment 3

[0043] (1) Take the radix radix radix seed kernels, freeze-dry them at low temperature in vacuum, and then use a sesame oil refiner (adjust the thickness of the disc of the refiner to pass 40 meshes) to refine the pulp to obtain the radix radix radix seed pulp, and refrigerate it for later use;

[0044] (2) Accurately weigh 20g of radix sorbifolium seed pulp, dissolve it with 80ml of sodium chloride aqueous solution with a concentration of 50g / L and place it in an ultrasonic extractor for extraction: adjust the ultrasonic power to 80KH Z , the stirring speed is 60r / min, the temperature is 60°C, and the extraction time is 120min;

[0045] (3) Centrifuge the extract with a high-speed centrifuge: the centrifugation temperature is 25°C, the centrifugation speed is 9000r / min, and the centrifugation time is 20min; after centrifugation, the upper layer is taken out to obtain pure natural Xanthania sorbifolia seed oil. The extraction rate is 61.54%.

Abstract

The invention discloses a method for preparing shiny-leaved yellowhorn kernel oil by adopting the ultrasound-assisted salt process and belongs to the field of food and healthcare food. The method comprises the following steps of: freezing and drying shiny-leaved yellowhorn kernels as raw materials at low temperature in vacuum, pulping, mixing pulps, extracting by promoting dissolving by adopting the ultrasound-assisted salt process, and centrifuging at high speed to obtain the high-quality shiny-leaved yellowhorn kernel oil. Because the shiny-leaved yellowhorn kernels are frozen and dried at low temperature in vacuum, the original components of the shiny-leaved yellowhorn kernels are protected from damage. Because the technology of extracting by promoting dissolving by adopting the ultrasound-assisted salt process is used for demulsifying, the oil can be extracted to the maximum extent, high oil yield can be achieved, and the problem of serious common water extraction and emulsification can be solved. Because the ultrasound-assisted salt process is used for extracting, the extracting cycle can be shortened, the energy consumption can be reduced, and high efficiency can be achieved. The method has the advantages that the reaction condition is mild, and the extracting process is environment-friendly.

Description

technical field [0001] The invention relates to a method for preparing Xantho sorbifolia seed oil, in particular to a method for preparing Xantho sorbifolia seed oil by an ultrasonic salt method, which belongs to the field of food and health food processing. Background technique [0002] Xingguan fruit is a unique woody oil tree species in my country, and its kernel oil content is 55%~65%. Among them, the unsaturated fatty acid content is as high as 94%. Its edible oil is delicious and rich in fragrance, and it is a high-grade health-care edible oil. Due to its high linoleic acid content, strong skin penetration, and remarkable health care functions, the massage industry also uses it as a base oil for massage. At present, the most commonly used method to extract Xanthos sorbifolium oil is ordinary water extraction. The extraction process requires frying the raw materials and extracting them at a higher temperature. This process easily leads to the oxidation of unsaturated ...
