Study on decortication and detoxification of bitter almond and decolorization of almond oil
Using orthogonal experiment methods to study almond decortication, detoxification of bitter and almond oil decoloring, then get the best technics parameters. The results of the almond decortication is better by soaking in the boiling alkaline liquor (pH value 9) for 5min. And it may completely remove the bitter of almond oil by soaking in the acid liquor(pH value 4, 35℃) for 36 hours. Using self-made to decolor the rough almond oil , the ratio of rough almond oil to decolorant is 20∶1,stirring for 5min at 85℃ and filting it, then may obtain the light yellow transparent decolorization almond oil.
