Wash the average fresh potato sample, dry the surface moisture, accurately weigh to 0.1g, cut into strips and spread on a porcelain plate, dry at 50+2℃ until it becomes brittle and easy to crush, take it out, cool it naturally to room temperature, accurately weigh to 0.01g, crush the dried sample, pass through a 60-mesh standard sieve, and put it into a ground-mouth bottle for determination.
A2.3.2 Weigh the average sweet potato slice sample, crush it, pass through a 60-mesh standard sieve, and put it into a ground-mouth bottle for determination. A2.4 Determination and calculation of starch content in raw materials
A2.4.1 The recommended method for determining the average starch content of samples after drying is the acid hydrolysis method in GB5009.9 and the polarimeter determination method in GB5006. A2.4.2 The starch content of raw materials is calculated according to formula (A2): t×100%
