Foreword

This standard is in accordance with GB Stew T1.1-1993 "Standardization Work Guide Unit 1. Standard Drafting and Expression Rules Part 1. Standard The basic provisions of the quasi-write are related to the requirements. This standard is one of the series of standards for this category of goods. The test method is related to domestic and foreign literature. On the basis of the investigation, it is determined that the headspace sampling device can be strictly controlled with parameters such as temperature, time and injection volume, and the volatiles in the oil can be used. A capillary chromatography system that quantitatively separates components (such as aromas) from residual solvents, making the test method suitable for the actual import and export of edible vegetable oils. Happening. Appendix A of this standard is an appendix to the tip. This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted. Shanghai Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China. The main drafters of this standard. Shen Zuhui, Xu Xifeng.

This standard is applicable to the determination of hydrocarbon solvent residues mainly composed of C6 paraffins in various edible vegetable oils extracted by leaching method. The provisions contained in the following standards constitute provisions of this standard by reference in this standard. At the time of publication of this standard, the versions shown are To be effective. All standards will be revised and parties using this standard should explore the possibility of using the latest version of the following standards. SN Stew T0800.1-1999 Import and export grain and oil feed inspection sampling and sample preparation method  Definition This standard uses the following definitions. . Residual solvent residualsolvent The extraction solvent in which the obtained vegetable oil is extracted by the leaching method and remains in the finished product after refining is referred to as a residual solvent. . base vegetable oil matrixvegetableoil A vegetable oil without residual solvent of the same variety as the sample to be tested. a refined vegetable oil obtained by a refining process such as deodorization and decolorization; or The leaching oil is degassed by heating under laboratory conditions, or heated to a high purity dry nitrogen gas and blown until the residual solvent disappears. Oil, etc. 抽样 Sampling and sample preparation Execute according to SN Stew T0800.1.  Determination method . Method principle The edible vegetable oil to be tested is placed in a closed container, and the volatile residual solvent present in the vegetable oil is diffused at a prescribed temperature. In the gas phase on the liquid surface, after a certain period of time, the dynamic equilibrium of the distribution concentration between the gas phase stew liquid phases is reached. Detection of the upper layer by headspace gas chromatography The content of residual solvent in the gas phase, and the results of the standard sample of edible vegetable oil with known residual solvent content under the same operating conditions By comparison, the actual amount of residual solvent in the sample to be tested can be calculated. . reagent ..  hexane. analytically pure. ..  Industrial hexane. a primary product, or a recycled solvent that has been recycled during the production process. The main component has a n-hexane content of not less than 50%.
