Embodiment 1

[0128] 1. Take 4Kg of refined shea olein with AV=0.5, triterpenoid alcohols and sterol content of 7.20%, add methanol and milk with a mass ratio (refined shea oil:methanol) of 3:1 Sodium methoxide with 0.7% mass of fruit liquid oil, reacted at 70°C for 2.5 h, separated the liquid, took the upper liquid, washed with water, stood still to separate the liquid, took the upper liquid, and distilled under reduced pressure to remove the residual solvent to obtain the transesterification product, The yield was 92.0%, and the content of triterpene alcohols and sterols was 7.13%.

[0129] 2. Take 1kg of the shea olein transesterification product obtained in the previous step, and carry out molecular distillation at a distillation temperature of 110°C, a rotation speed of 250rpm, and a pressure of 10 -3 mbar. A 130 g heavy phase sample was obtained by distillation, and the content of triterpene alcohols and sterols was 50.86%. (The specific content of unsaponifiable matter in molecular...

Abstract

The invention provides a method for extracting unsaponifiable matters from shea butter oil. The method comprises the steps of ester exchange, molecular distillation, crystallization and the like. An unsaponifiable matter composition with high purity can be obtained by adopting the method. The content of the unsaponifiable matters in the composition can reach 60%, 70% or even higher; the composition contains high contents of triterpene alcohols and sterol which can exist in the form of solids; the shelf life of the unsaponifiable matters is prolonged; the unsaponifiable matters can be applied to various purposes.

Description

technical field [0001] The invention relates to a method for extracting unsaponifiable matter from Shea olein. Background technique [0002] Shea olein is a liquid or semi-solid fat product obtained from shea butter through fractionation and other processes. Shea butter is a natural light yellow semi-solid oil extracted from African shea nuts. [0003] Shea butter can effectively prevent solar dermatitis, and has anti-aging and high moisturizing effects. Shea butter is the closest to the indicators of human sebum secretion and oil. It contains rich non-saponifiable ingredients and is easy to absorb by the human body. It can not only prevent dryness and cracking, but also further restore and maintain the natural elasticity of the skin. Moisturizing effect. [0004] According to historical records, the indigenous people of Africa often used shea butter in ointments to treat rheumatic pains and boils. Aboriginal people massage newborn babies with shea butter to protect thei...
