Problems solved by technology

The physical method usually uses mechanical force to squeeze the raw material to produce oil. The process is simple, the oil yield is low, and the residual oil of the oil residue is high, which is easy to cause a certain degree of waste; the chemical method usually takes a long time to extract and consumes a lot of solvent. High chemical residues of solvents, resulting in poor quality oils

Embodiment 1

[0034] The preparation method of refined almond oil comprises the following steps:

[0035] (1) Select the almonds produced in the current year, crush them to 40 meshes, put them into a hot air dryer and dry them with hot air at 800°C to obtain almonds with a moisture content of 3wt%;

[0036] (2) Extraction of crude oil: the almond with a moisture content of 3wt% is subjected to supercritical CO 2 Fluid extraction, adding entrainer during the extraction process, in which CO 2 The flow rate is 15kg / h, the flow rate of the entrainer is 0.9kg / h, the extraction pressure is 35Mpa, the extraction temperature is 36°C, and the extraction time is 2h to obtain crude oil;

[0037] (3) Alkali refining deacidification: mix crude oil and sodium hydroxide aqueous solution at a mass ratio of 100:1, wherein the concentration of sodium hydroxide in the sodium hydroxide aqueous solution is 15wt%, 300 rpm, stir for 30min, and centrifuge , to obtain deacidified oil, stir and mix the deacidified...

Embodiment 2

[0044] It is basically the same as Example 1, the difference is only that: in the step (2), the entrainer is composed of 1,2-propanediol and glycerin, wherein the flow rate of 1,2-propanediol is 0.45kg / h, and the flow rate of glycerin is 0.45kg / h. The refined almond oil of embodiment 2 can be obtained.

Embodiment 3

[0046] It is basically the same as Example 1, the difference is only that: in the step (2), the entrainer is composed of 1,2-propanediol and 1,3-propanediol, wherein the flow rate of 1,2-propanediol is 0.45kg / h, 1, The flow rate of 3-propanediol is 0.45kg / h. The refined almond oil of embodiment 3 can be obtained.

Abstract

The invention discloses refined apricot kernel oil and a preparing method thereof.The preparing method comprises the steps of 1, smashing and drying apricot kernels to obtain apricot kernels with water content being 1-5 wt%; 2, conducting supercritical CO2 fluid extraction on the apricot kernels with water content being 1-5 wt%, and adding an entrainer during extraction to obtain crude oil; 3, mixing the crude oil with sodium hydroxide aqueous solution according to the mass ratio of (95-105) : (0.5-1.5), conducting stirring for 25-35 min, conducting centrifugal separation to obtain deacidified oil, and evenly mixing the deacidified oil with carotenoid according to the mass ratio of (95-105) : (0.05-0.5) to obtain mixed oil; 4, conducting sediment; 5, conducting filtration.The extraction technology is mature, easy to operate and environmentally friendly, and meanwhile, the method has the advantages that yield and purity are high, and the quality of prepared apricot kernel oil is high; a beautifying function and a lung clearing and moistening healthcare function are realized.

Description

technical field [0001] The invention relates to the technical field of oil processing, in particular to a refined almond oil and a preparation method thereof. Background technique [0002] Almond, Latin scientific name Amygdalus Communis Vas, is the seed of Rosaceae apricot, divided into sweet almond and bitter almond, mainly containing protein, fat, sugar, and trace amounts of amygdalin. Fats are mainly composed of oleic acid and linoleic acid. The almond fruit grows on short spurs and has an immature appearance. When the fruit is ripe, its green shell splits open, revealing the nucleolus wrapped in a rough shell, which is yellow and has many small holes, and the shell is hard wood. The almond fruit is flat oval, with a round end and a pointed end, covered with a thin brown skin. [0003] Almonds contain 20% protein and do not contain starch. After being ground and pressurized, the oil extracted is about half of its own weight. Almond oil, light yellow and transparent, ...
