Embodiment 1

[0031] This embodiment is used to illustrate the method for preparing shea butter using subcritical propane extraction technology of the present invention, and the specific steps are as follows:

[0032] Step 1: Cleaning the shea nut cores, then freeze-drying, controlling the water content to 2%, and then crushing the shea nut kernels into fine powders of about 40-80 mesh with a pulverizer for future use.

[0033] Step 2: Weigh a certain amount of shea nut powder and pack it in a 120-mesh filter bag, put it into the extraction tank, and then evacuate to reduce the pressure in the extraction tank to -0.1MPa.

[0034] Step 3: Import the extraction solvent propane from the solvent tank into the extraction tank, and extract according to the set conditions; the set conditions include: extraction pressure 0.2MPa, extraction temperature 20°C, solid-liquid ratio 1:3, extraction times 2 times, each extraction time is 40min.

[0035] Step 4: After the extraction, use a booster pump to ...

Abstract

The invention belongs to the technical field of subcritical fluid extraction, and relates to a method for preparing shea butter by adopting a subcritical propane extraction technology, the shea butterand application. On the basis of a single-factor test, an orthogonal test is adopted to optimize key parameters influencing the shea butter yield, the optimal process conditions are determined, and the prepared shea butter can be used for preparing functional foods capable of keeping skin elasticity and blocking the sun.

Description

technical field [0001] The invention belongs to the technical field of subcritical fluid extraction, and more specifically relates to a method for preparing shea butter by adopting subcritical propane extraction technology, shea butter and its application. Background technique [0002] Shea butter, also known as shea butter, is extracted from the fruit of shea butter (or shea tree, shea tree) unique to West and Central Africa - Shea nut. Tropical woody oil is a typical non-drying oil, and its main components are triglycerides and unsaponifiables. The most valuable part of shea butter is the unsaponifiable part. Vegetable oil generally contains less than 1% of unsaponifiable, while the content of unsaponifiable in shea butter is as high as 7% to 11%, mainly phytosterols and tocopherols. Shea butter has a high content of unsaponifiable matter, high oil solubility, and is safe and non-toxic. In view of its unique edible, cosmetic and medical value, skin care products and hair...
