活性炭脱色对大豆磷脂质量的影响

EFFECT OF ACTIVATED CARBON ON QUALITY OF SOYBEAN LECITHIN

采用活性炭对大豆浓缩磷脂进行脱色 ,发现活性炭对磷脂有一定的脱色作用 ,也对磷脂质量产生副作用 .活性炭的酸性及脱色温度的联合作用 ,促使磷脂轻度水解和氧化 .对磷脂脱色优化条件为 :活性炭加入量 4%、脱色温度 40℃、脱色时间 2

A concentrated soybean lecithin was bleached by activated carbon in laboratory.It discovers that activated carbon has bleaching effect on soybean lecithin and has some negative effects on soybean lecithin quality.Acidity of activated carbon and temperature can make lecithin hydrolyzing and oxidizing slightly.The optimal conditions are 4% of activated carbon,bleaching temperature 40℃ and bleaching time 20min.
