(National food safety standards for food additives vegetable oil extraction solvent (aka hexane solvent)) National Standards of People's Republic of China National Food Safety Standard Food additive vegetable oil extraction solvent (Also known as hexane solvent) Issued on. 2015-09-22 2016-03-22 implementation People's Republic of China National Health and Family Planning Commission released National Food Safety Standard Food additive vegetable oil extraction solvent (Also known as hexane solvent) 1 ScopeThis standard applies to straight-run distillate from petroleum refined and prepared food additive vegetable oil extraction solvent (aka hexane solvent), the Products such as hexane, fat is mainly composed of hydrocarbons.2 Technical Requirements2.1 Sensory requirements Sensory requirements shall comply with the requirements of Table 1. Table 1 Sensory requirements Project requires test methods Color colorless State transparent liquid without mechanical impurities Take appropriate sample is placed in a clean, dry cuvette, under natural light, Views Its color and state police 2.2 Physical indicators Physical and chemical indicators should be consistent with the provisions of Table 2. Table 2. Physical and chemical indicators Item Index Test Method Distillation Range (IBP to dry point)/℃ 61 ~ 76 GB/T 6536 Benzene, w /% ≤ 0.06 GB/T 17474 Evaporation residue/(mg/L) ≤ 10 GB/T 3209 Sulfur (S)/(mg/kg) ≤ 5.0 SH/T 0253 Lead (Pb)/(mg/kg) ≤ 1.0 GB 5009.12 PAHs experimentally Appendix A A.3 by pH test A.4 in Appendix AAppendix ATesting method A.1 General Provisions This standard reagents and water, did not indicate when the other requirements, refer to the three water analytical reagent and GB/T 6682 regulations. test Test used in the standard solution, impurity standard solution, preparations and products, did not indicate when the other requirements, according to GB/T 601, GB/T 602, GB/T 603 provisions prepared. Solution was used in the tests did not indicate what is formulated with solvent, it refers to an aqueous solution. A.2 Identification Test A.2.1 solubility Insoluble in water, soluble in ether, ethanol and acetone. A.2.2 Density Density by GB/T 1884 and the provisions of GB/T 1885 progresses, density range (20 ℃) of 0.655g/cm3 ~ 0.680g/cm3. A.3 Determination of Polycyclic Aromatic Hydrocarbons A.3.1 Reagents and materials A.3.1.1 dimethyl sulfoxide. A.3.1.2 trimethyl pentane solution of naphthalene. 7.0mg/L. A.3.2 Analysis step Pipette 25.0mL sample is placed in a separatory funnel and 125mL, 25mL of hexane was added and mixed. Dimethyl sulfoxide was added 5.0mL, severe Oscillation 1min, standing stratification. Another solution is to take the lower separating funnel, shaken vigorously after adding 2mL hexane. Still stratification, separation under Layer solution. While 25mL of hexane was added 5.0mL of dimethyl sulfoxide, after vigorous shaking 1min lower solution was to do a reference in 260nm ~ 420nm measured absorbance. Another solution of naphthalene-trimethylpentane, trimethyl pentane do reference, the solution was measured at the absorbance at 275nm, as for According to value. A.3.3 results found All samples absorption peaks in the range of 260nm ~ 420nm, absorbance does not exceed one third of the control values, namely through test. A.4 pH measurement A.4.1 Reagents A.4.1.1 ethanol. A.4.1.2 buffer solution. with two buffer solutions, the test sample should be close to the expected pH. A.4.2 Instruments A.4.2.1 pH meter. including temperature compensation system, the accuracy of at least 0.02. A.4.2.2 electrode or composite electrode triple. A.4.3 Analysis step The electrode was washed with water and a standard buffer solution is placed in a test environment, between ambient temperature and the temperature as close as possible to each other. Select two Species appropriate standard buffer solution, according to the instrument manual calibration of pH meter. After instrument calibration, first rinse electrode, then dry with filter paper. Take appropriate sample in a beaker, and carefully insert the electrode in the sample, The electrode is immersed, to be pH meter reading to stabilize and record the readings. A.4.4 results found The measurement results for the arithmetic mean of two parallel determination results of two parallel determination results shall not be greater than the absolute difference 0.1. pH measurement results within the range of 3.0 to 4.4 experimentally. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB 1886.52-2015_English be delivered?Answer: Upon your order, we will start to translate GB 1886.52-2015_English as soon as possible, and keep you informed of the progress.
