It is prepared and calibrated according to the method specified in GB/T 601. B.1.2 Methyl orange indicator solution (0.1%). Weigh 0.1 g of methyl orange and dissolve it in 70 °C distilled water, cool and dilute to 100 mL. B.2 Apparatus Acid burette. 25 mL. B.3 Preparation of test specimen and test solutions Prepare the test specimen and test solution according to the method specified in GB/T 12456. B.4 Analysis steps Pipette 50 mL of the test solution and place it in a 250 mL conical flask. Add two drops of methyl orange indicator solution and titrate with hydrochloric acid standard solution (0.05 mol/L) until a reddish color appears. Record the volume of hydrochloric acid standard solution consumed. At the same time, perform a blank test with distilled water. B.5 Presentation of analysis results The alkalinity X of the biscuit is expressed as the number of grams of sodium carbonate contained in 100 g of the specimen and is calculated according to formula (B.1). where X -- alkalinity, in grams per hundred grams (g/100 g); c -- the actual concentration of hydrochloric acid standard solution, in moles per liter (mol/L); V1 -- the volume of hydrochloric acid standard solution consumed when titratingAppendix C(Normative) Bulk density test method C.1 Calculation method (arbitration method) C.1.1 Apparatus C.1.1.1 Vernier caliper. The accuracy is 0.02 mm. C.1.1.2 Balance. The range is 1 g~500 g, and the accuracy is 0.1 g. C.1.2 Analysis steps Take a sample with a volume of at least 25 cm3, weigh its mass m (g) with a balance, and then use a vernier caliper to measure its length, width and height respectively, and calculate the volume V (cm3) mathematically. C.1.3 Presentation of analysis results The bulk density P of biscuits is expressed as mass per unit volume and is calculated according to formula (C.1). where P -- bulk density, in grams per cubic centimeter (g/cm3); m -- the mass of the sample, in grams (g); V -- the volume of the sample, in cubic centimeters (cm3). C.1.4 Allowable difference The difference between two measured values of the same sample shall not exceed 2% of the average value of the two measurements.
