为了探明脱色对冷榨茶油品质的影响,以冷榨(≤65 ℃)毛茶油为原料,采用竹炭/活性白土复合脱色剂脱色,测定脱色前后茶油的理化指标、主要生物活性成分、脂肪酸组成与含量、感官品质以及流变学性能。本研究采用的脱色工艺能使冷榨茶油达到无色状态(YORO),经脱色后,其酸价和过氧化值分别降至0.05 mg. g~(-1)和0.52 mmol. kg~(-1),处于非常低的水平;除类胡萝卜素以外,脱色对茶油中的生物活性成分均无明显影响;脱色后,冷榨茶油的风味值仅为0.3分,接近无味状态;而且,脱色也未改变冷榨茶油的脂肪酸组成与含量;此外,脱色对茶油的流变学性能亦无明显影响。脱色处理不仅能使冷榨茶油满足化妆品用油无色、无...

The paper was aimed to investigate the effect of decolorization on Camellia oleifera Abel seed oil quality (COASO) cold-pressed. Crude COASO prepared under low temperature (≤65℃) had been taken as the material and bamboo charcoal/activated clay as compound decolorant; the mainly important indexes including physicochemical index, main bioactive components in COASO, fatty acid composition & content, sensory quality and rheological properties were measured before and after the decolorization process. Decolorization technology was used in the...
