Foreword
This standard replaces GB/T 8885-1988 "edible corn starch."
The main difference compared with the standard GB/T 8885-1988 as follows.
--- According to food safety and hygiene requirements and international practice, increasing the microbiological criteria;
--- Increased inspection rules;
--- Sensory requirements revised. the appearance and odor, taste and impurities cancel two;
--- Color, whiteness no longer by white corn, yellow corn value;
--- Unified revised each grade water to no more than 14.0%;
--- Acidity amended as follows. superior grade of no more than 1.50 ° T, a product of not more than 1.80 ° T, the two products does not exceed 2.00 ° T;
