Research of the decolorizing technology for tea seed oil.

With machine pressed tea seed oil as raw material, bleaching of the absorption process conditions were studied. Choose activated clay for bleaching adsorbent, based on single factor test, the best conditions of tea seed oil decolorizing by orthogonal test are determined as follows: the additive amount of adsorbent is 3.0% , the bleaching temperature is 90℃,the bleaching time being 25min while the agitation speed is 160r/min, which can make the decolorizing rate add to 79.32%.
