The grease of the edible that stabilizes to acquire high quality through physical Refinery contains phosphor to measure Z ～ SPpm at the same time also purify iron. It is indispensible that oil applies special honest legal system to take crude oil according to Ong we are preliminary the result of research shows as a result of,Sunflower oil reports easily distillation (namely de-acidification) de-acidification compares traditional deodorization temperature to undertake degum NHP content comparatives low. The crude oil of different quality undertakes below tall condition. Quantity of undesirable compound remain is 8 ～ 20ppm under use water or quantity of phosphor of the incomplete after a few acerbity come unglued even. Alkaline oil refining. So low to soybean oil cost applies multistage come unglued only important in the undesirable compound of the purify before de-acidification is craft just can be achieved. Phosphatide. The pretreatment of grease physics refine that allowance of incomplete of the phosphatide after pretreatment is regarded as to apply at industry to produce even is versed in the standard of physical Refinery oily stability. Be not to hydrate sex the combined action that phosphatide art basically includes 12 process. If heat, water (NHP) basically is phosphatide acid and dissolve implement cent adjustment, detached, bath mixes the calcic, magnesium of phosphatide acid dry these processes are complex salt it is one of material of the most difficult purify in de-acidification pretreatment working procedure. and the auxiliary material with much need. According to our research NHP uses acerbity purify. Use phosphoric acid citric acid normally or do not need a such strengthened pretreatment with Sunflower oil blame. . .

Rice bran oil is oil of a kind of high grade edible often oil of edible rice bran prevents the symptom such as arteriosclerosis hypertension to have favorable curative effect to reducing cholesterol of human body serum  . More FFA is contained in rice bran oil, not saponification content and colour and lustre hard Refinery uses chemical Refinery to existing black foot estimates loss of big, Refinery the defect such as environment of tall, pollution. In last few years physical Refinery with craft simple, without the environment pollution, oily cost is low as good as product quality and get of people take seriously especially rice bran of high acid value is oily its advantage is more distinct. The pretreatment before physical Refinery includes distillation and distillation de-acidification two phase. Because pretreatment is right,the quality of physical Refinery oil is having conclusive effect  . Consider to basically be centered at pretreatment respect to the physical Refinery of rice bran oil in last few years. Foreign scholar  is opposite in rice bran oily pretreatment influence of rice bran oily quality undertook study. 1 material and rice bran of material of methodological 1 1 (contain 124 % ) of ～ of FFA 40 % , phosphoric acid (provision level) 1 2 determines the FFA in oil of methodological wool rice bran and Refinery oil, cross oxidation to be worth (PV) , not saponification content, colour and lustre all uses AOCS standard method  . Colloid measure with total candle with acetone not the computation of 100 minutes of content of dissolve content. Accurate in cone-shaped bottle metage measures rice bran certainly. . .
