Determination of soap content in vegetable oils ICS 67.040 X04 National Standards of People's Republic of China Replacing GB/T 5533-1985 Determination of the amount of soap Inspection of grain and vegetable oils containing Posted 2008-11-04 2009-01-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis revised standard adopts the American Oil Chemical Society (AOCS) standard AOCSCC17-95 "fat content in soap titration" (English Chinese Version). This standard AOCSCC17-95 main technical differences. --- Modify the definition of soap-containing volume; --- In order to facilitate titration "150mm × 40mm stoppered test tube" to "250mL conical flask with stopper"; --- Modify the result of the calculation formula and method of expression. This standard replaces GB/T 5533-1985 "Inspection of vegetable oils containing soap quantity determination." This standard and GB/T 5533-1985 compared to the main changes are as follows. --- The scope changed to "applicable to refined vegetable oils and fats"; --- The sample is dissolved reagent "petroleum ether" to "aqueous acetone"; --- The sample was weighed by the amount of "10g" changed to "40g"; --- The "0.02N solution of sulfuric acid" was changed to "0.01mol/L hydrochloric acid solution"; --- The "0.2% methyl red ethanol solution" was changed to "1% bromophenol blue solution"; --- The indicator is added to the aqueous acetone, aqueous acetone and adjusted to neutral; --- Increasing the blank test requirements; --- Test will allow double the difference "does not exceed 0.02%" to "not more than 0.01%." The standard proposed by the National Food Authority. This standard by the National Standardization Technical Committee OILS. This standard is drafted by. Nanjing University of Finance and Economics, Academy of State Administration of Grain. Drafters of this standard. Yuan Jian, OILS, Theorizing, Xue Yalin. This standard replaces the standards previously issued as follows. --- GB/T 5533-1985.
