Embodiment 1

[0029] Bitter almonds are obtained by cracking the shells of bitter almond seeds, and pressed at room temperature (20-28° C.) to obtain bitter almond fat oil and defatted bitter almonds. Measure the content of 7 mg / kg cyanide in bitter almond fat oil, estimate the cyanide content of the detoxified bitter almond oil obtained by final washing is less than 0.2 mg / kg, need to extract 4 times.

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

[0031] Take 10g of the oil phase (supernatant) for detection, and continue to treat the remaining oil phase in the same way: extract with 4 times the volume of water, then centrifuge at low speed (500 rpm) and high speed (8000 rpm) to separate the oil phase and water Phase, repeat 3 times.

Embodiment 2

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

[0037] Measure 100ml of bitter almond fat oil that contains cyanide, add 6 times of volume (600ml) drinking water, stir at a rotating speed of 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 process conta...

Embodiment 3

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

[0043] Get 100mL of bitter almond fat oil containing cyanide, add 4 times the volume (400ml) of drinking water, stir at a speed of 550 rpm for 10 minutes, and then let stand for 10 minutes to remove the water phase; Add 400ml of drinking water to the oil phase, stir at 550 rpm for 10 minutes, then let it stand for 10 minutes to remove the water phase; repeat the treatment 3 times in the same way. Centrifuge the oil phase obtained in the fourth separation at 8000 rpm, take 10 g of oil from the oil phase for testing, add the rest of the oil to 400 ml of drinking water, stir at 550 rpm for 10 minutes, then let stand for 10 minutes,...

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 cracking the shells of the mature seeds of the plants of the genus Prunus in the Rosaceae family. Bitter almonds are rich in fatty oils, including a large amount of oleic acid and linoleic acid, which have important physiological effects and medicinal value on the human body. [0003] 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 nutrition, food, medicine and light industry: it can be used as skin care cosmetics Raw materials for raw materials, lubricating oil for precision instruments, medical industrial oil, advanced coatings, food additives, etc., and it is a good edible oil. [0004] Studies have found that almond oil can inhibit the biosynt...
