Table 3 Microbiological Item Detection limit Cfu/(CFU/g) ≤ 3000 GB 4789.2 Coliforms/(CFU/g) ≤ 10 GB 4789.3 Plate Count Molds and yeasts/(CFU/g) ≤ 100 GB 4789.15 Escherichia coli/(CFU/g) < 10 GB 4789.38 Plate Count Salmonella/25g Not detected GB 4789.4 Staphylococcus aureus/25g not be detected GB 4789.10 qualitative test3 LabelingSelenium enriched yeast tag identification shall indicate the total selenium content.Appendix ATesting method A.1 General Provisions Unless otherwise specified in this standard, the purity of the reagents used were of analytical grade, standard titration solution used, the impurity determined by standard solution formulation And products shall GB/T 601, GB/T 602, a predetermined preparation GB/T 603, the test water shall meet the GB/T 6682 in three water gauge set. The test does not indicate when the solution which is formulated with a solvent, refer to the aqueous solution. A.2 Determination of the mass fraction of the total selenium organic selenium A.2.1 Reagents and materials GB 5009.93-2010 with the first method. A.2.2 Instruments and Equipment GB 5009.93-2010 with the first method. Preparation of inorganic selenium measurement sample A.2.3 A.2.5.2 content of organic selenium X2, in milligrams per kilogram (mg/kg), calculated according to formula (A.2). X2 = X-X1 (A.2) Where. X---- total content of selenium in the sample, in milligrams per kilogram (mg/kg); The content of the X1 --- inorganic selenium in the sample, in milligrams per kilogram (mg/kg). Of the total selenium content of organic selenium A.2.5.3 mass fraction w1, according to equation (A.3) is calculated. w1 = X2 X × 100% (A.3) Where. An X2 --- selenium content of the organic sample, in milligrams per kilogram (mg/kg); X---- total content of selenium in the sample, in milligrams per kilogram (mg/kg). The test result to the arithmetic mean of replicates results. Results reserved to a decimal point. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB 1903.21-2016_English be delivered?Answer: Upon your order, we will start to translate GB 1903.21-2016_English as soon as possible, and keep you informed of the progress.
