This Standard is applicable to food additive - vanillin, which is prepared by chemical reaction with guaiacol or sulfite pulp waste liquid lignin or p-cresol as raw materials. 2 Chemical name, molecular formula, structural formula and relative molecular mass 2.1 Chemical name 3-methoxy-4-hydroxybenzaldehyde 2.2 Molecular formula C8H8O3 2.3 Structural formula 2.4 Relative molecular mass 152.15 (according to 2007 international relative atomic mass).3 Technical requirements
3.1 Sensory requirements The sensory requirements shall meet the requirements of Table 1.Annex A
Determination of vanillin content A.1 Instruments and equipment A.1.1 Chromatograph: according to the provisions of Clause 5 in GB/T 11538- 2006 or GB/T 11539-2008. A.1.2 Column: capillary column or packed column. A.1.3 Detector: hydrogen flame ionization detector. A.2 Determination method Sample preparation: Weigh 1g of the sample and dissolve it in 10mL of 95% (volume fraction) ethanol. Shake well and leave for later use (use within 30min). Area normalization method: Determine the content according to 10.4 in GB/T 11538-2006 or GB/T 11539-2008. A.3 Repeatability and result presentation According to GB/T 11538-2006 or 11.4 in GB/T 11539-2008. See Annex B for the gas chromatogram of food additive - vanillin (area normalization method). ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
