摘要
提出了改性膨润土无水精炼油茶籽油工艺,该工艺先用活性白土脱色,然后用碱性钙基膨润土脱酸,在脱色及脱酸的同时进行了脱胶,并对脱色与脱酸工艺的条件进行优化。结果表明:改性膨润土无水精炼油茶籽油工艺能满足油茶籽油的脱色、脱酸、脱胶要求,过氧化值与杂质含量也有一定的下降,极大地简化了油品的精炼工艺,降低了生产成本。
The refining technology of oil-tea Camellia seed oil using modified bentonite without water was investigated. Oil-tea Camellia seed oil was bleached by activated clay, and then deacidified by alkaline Ca-bentonite ,while it was degummed simultaneously in this two processes. Conditions of the bleaching and deacidification processes were optimized. The results indicated that the refining technology could meet the demands of bleaching,deacidification and degumming of oil-tea Camellia seed oil, and could decrease the peroxide value and the content of impurity in some extent. The present technology simplifies the refining process of oil-tea Camellia seed oil and decreases cost in a great extent.
