Foreword

This standard replaces GB 10287-1988 < < food additives rosin ester and hydrogenated rosin ester >>. This standard compared with GB 10287-1988, the main changes are as follows. - Modify the main ingredient and naming, adds structural formula of the major component (see Chapter 3); - Increase the sensory requirements (see Table 1); - Modify the physical and chemical indicators of "solubility" to "soluble" (see Table 2); - Modify the acid value by 3.0 ~ 9.0mgKOH/g to ≤9.0mg/g; - Modified hydrogenated rosin ester softening point from 88.0 to 78.0 - 78.0 to 90.0 (see Table 2); - Modified rosin ester relative density from 1.080 to 1.060 - 1.090 - 1.090 (see Table 2); - Modified hydrogenated rosin ester relative density from 1.060 to 1.060 - 1.070 - 1.090 (see Table 2); - Modify the total arsenic (As) Limited index from 0.0002% to 1.0mg/kg, to a reference test method GB/T 5009.11 (See Table 2); - Modify the heavy metals (Pb) Limited index from 0.002% to 10.0mg/kg, to a reference test method GB/T 5009.74 (See Table 2); - Modify the proportion to the relative density and the modified formula (see Table 2, Appendix A.4); - Modify the acid value, determination of ash instead direct reference (see Table 2).

Appendix A

Testing method A.1 General Provisions Unless otherwise indicated in the analysis using only confirm three analytical grade reagents and water GB/T 6682-2008 stipulated. Test Methods standard titration solution, when measured impurity standard solution, preparations and products, with no other requirements noted, According to GB/T 601, the provisions of GB/T 602 and GB/T 603 of the preparation. Test methods used in the solution when the solvent is not specified, all refer to water Solution. A.2 Identification Test Infrared Spectroscopy A.2.1 Instruments and Equipment infrared spectrometer. A.2.2 Sample Preparation Potassium bromide tablet method. The sample was ground into powder, adding an appropriate amount of potassium bromide, mixing and grinding evenly, with tableting machine into a uniform and transparent thin membrane. A.2.3 Identification Test The sample was placed in a test infrared spectrometer, infrared spectra obtained with the rosin ester appendix infrared spectrum B (see Figure B.1) Hydrogenated and infrared spectrum (see Figure B.2) should be consistent. A.3 Determination of solubility A sample with toluene 1. 1 (mass ratio) was dissolved, into a clean, dry, transparent glass tube, in order to diffuse light under lateral entry Depending on the way were observed. The liquid should be clear and transparent, no impurities, no suspension. A.4 Determination of relative density A.4.1 Analysis step A.4.1.1 Take about 10 g bulk sample, remove surface debris, check should be free of cracks and bubbles, smooth surface. A.4.1.2 Take a wire diameter of less than 0.15 mm, it said accurate to 0.001 g. The wire in the alcohol lamp heating, hot insertion block Depth form samples approximately 2 mm ~ 3 mm, cooled, the wire will hang in the balance one end of the sample, weighed to the nearest 0.001 g. A.4.1.3 The hanging sample is immersed in 25 ℃ ± 0.5 ℃ water thermostat 0.5 h ~ 1 h after removal. Then there was immersed in 25 ℃ ± 2 ℃ Water beaker (beaker on a tripod support, not in contact with the pan). Samples from the upper level of not less than 1 cm, the surface of the specimen shall be attached Bubbles. Rapid weighing, accurate to 0.001 g. A.4.2 Calculation Results Relative density 2525d said, according to the formula (A.1) Calculated. Where. m-- sample and wire in the air mass in grams (g); m1-- sample and the quality of the wire in the water, in grams (g); m2-- wire in the air mass in grams (g); ρ25-- relative density of water at 25 ℃ when. The absolute difference between two parallel determinations should be less than 0.005, the arithmetic mean value for the report.
