Embodiment 1

[0029] Bitter almonds are obtained by breaking the shells of bitter apricot seeds, and pressed at room temperature (20-28° C.) to obtain bitter almond fat oil and defatted bitter almonds. The cyanide content in the bitter almond oil was measured to be 7 mg / kg, and it was estimated that the cyanide content of the detoxified bitter almond oil obtained by the final washing was less than 0.2 mg / kg, requiring 4 extractions.

[0030] Measure 100ml of bitter almond fat oil containing cyanide, add 400ml of drinking water, stir at 500 rpm for 10 minutes, then let stand for 10 minutes, remove the water phase, and separate the oil phase and the water phase; The phases were centrifuged at 8000 rpm for 10 minutes.

[0031] Take 10 g of the oil phase (supernatant) for detection, and the remaining oil phase continues to be processed in the same way: extraction with 4 times the volume of water, and then centrifugation at low speed (500 rpm) and high speed (8000 rpm) to separate oil phase and ...

Embodiment 2

[0036] Bitter almonds are obtained by breaking the shells of bitter apricot seeds, and pressed at room temperature (20-28° C.) to obtain bitter almond fat oil and defatted bitter almonds. The cyanide content in the bitter almond oil was measured to be 2.4549 mg / kg, and it was estimated that the cyanide content of the detoxified bitter almond oil obtained by the final washing was 0.06 mg / kg, which required 4 extractions.

[0037] Measure 100ml of bitter almond fatty oil containing cyanide, add 6 times the volume (600ml) of drinking water, stir at 550 rpm for 20 minutes, and then let stand for 10 minutes, remove the water phase, and separate the oil phase and the water phase; The resulting oil phase was then centrifuged at 9000 rpm for 15 minutes.

[0038] Take 10 g of the oil phase (supernatant) for detection, and continue to process the remaining oil phase in the same way, repeating 4 times. Utilize above-mentioned embodiment to handle cyano bitter almond fatty oil, and the c...

Embodiment 3

[0042] Compared with Examples 1 and 2, the difference in this example is that the separation process of the oil phase and the water phase after the water washing and extraction is different. In this example, the oil phase obtained for the first extraction is continuously extracted, and then centrifuged, which saves money. amount of extraction water.

[0043] Take 100 mL of bitter almond fatty oil containing cyanide, add 4 times the volume (400 mL) of drinking water, stir at 550 rpm for 10 minutes, and then let stand for 10 minutes to remove the water phase; Add 400 ml of drinking water to the oil phase, stir at a speed of 550 rpm for 10 minutes, and then stand for 10 minutes to remove the water phase; repeat the treatment three times in the same manner. The oil phase obtained from the 4th separation was centrifuged at 8000 rpm, and 10 g of oil in the oil phase was taken for testing. The remaining oil was added with 400 ml of drinking water, stirred for 10 minutes at a rotation...

Abstract

The invention provides a method for producing detoxified almond oil, which uses a bitter almond as a raw material. The method comprises: a shell breaking step, in which, a shell of a bitter almond seed is broken, and a bitter almond is separated; a cold pressing step, in which, the bitter almond is subjected to cold pressing under a condition of room temperature to obtain bitter almond fatty oil and degreased bitter almond; and an extracting step, in which, the bitter almond fatty oil is put into a vessel with 4 to 8 times of water by weight to be mixed into paste, and oil phase and water phase are centrifugalized; and the separated oil phase is extracted for 2 to 5 times by 4 to 8 times of water by weight, and the finally separated oil phase is the detoxified almond oil. In the detoxified almond oil produced by the method for producing the detoxified almond oil, residual cyanide is below 0.2 mg / kg. Compared with International Standards for Drinking Water of the World Health Organization in 1963, which suggests that the maximum allowable concentration of the cyanide of the drinking water based on health is 0.2 mg / kg, the detoxified almond oil produced by the method reaches the standard regulated by the International Standards for Drinking water, and is healthy and natural almond fatty oil.

Description

technical field [0001] The invention belongs to the technical field of healthy development of almond oil, in particular to a production method of detoxified almond oil. Background technique [0002] Bitter almonds are obtained by breaking the shell of the mature seeds of apricots and apricots in the genus Rosaceae. Bitter almonds are rich in fatty oil, which contains a lot of oleic acid and linoleic acid, which have important physiological effects and medicinal value on the human body. [0003] The almond oil extracted from bitter almonds is a non-drying oil, which remains clear at -10°C and solidifies at -20°C. It has great application value in nutritional food, medicinal and light industries: it can be used as skin care cosmetics raw materials, lubricating oil for precision instruments, medical industrial oil, advanced coatings, food additives, etc., and is the best edible oil. [0004] Studies have found that almond oil can inhibit the biosynthesis of cholesterol and in...
