This standard is revised on the basis of the original national standard GB797-188 Linalyl Acetate (this standard has a conversion standard number of GB/3760-1999 issued by the Ministry of Light Industry [1], and the content is the same as before). This standard is equivalent to the use of the US FCC: TV: 199% of the "3 / 3" content of the "flavor and ester" in the United States Food Chemicals Codex W: 996, and the technical indicators are completely consistent with the United States Food Chemicals Codex W: 996, and some of the standards are based on FCC TV: 1996. The inspection method uses the general test method of the flavoring industry, and the general test method is mostly equivalent to the [50% standard. The Appendix A of this standard is the reference.
This standard is proposed by the General Business Department of the China Federation of Industry and Commerce. This standard is the international standard for the international fragrance standard of the world, and is drafted by the Shanghai Flavor Research Institute and the Shanghai Zhongbao Flavor Industry Co., Ltd. The main drafters of this standard are: Xu Yi, Zhang Xinjun, and Xu Caiqi. Since the implementation of this standard, the light industry standard QRT17601999 issued by the former State Light Industry Bureau is 1.

6.1 The acid aromatic elastic aldehyde should be supervised by the inspection department of the manufacturer: production! It should be confirmed that the products meet the requirements of this standard. 6.2 Check the quality of the products received in accordance with the requirements of the standard. Each batch number is inspected once: different from the batch acceptance. 6.3 Best method: For each unit of less than 100 units, take 3 units, and for more than 100 units, take 3 units. When not only loading and unloading, appearance inspection After the mixture is dried and free of water and impurities, the slurry is fully drawn, and 50ml to 10ml of the mixture is pipetted into a glass sample tube, injected into a sample limiter and mixed evenly, and then loaded into two glass plates that are clean and grinded. The sample should be marked with: manufacturer name, product name, production date, batch number, address and date. It can be used for short-term inspection and stored for future reference. 5.4 If there are certain indicators that do not meet the requirements of this standard in the acceptance results, the manufacturer can be consulted to take or re-sample twice the amount. If there are still indicators that do not meet the requirements, the product cannot be accepted. 6.5 If the supplier raises objections to product items, the two parties can agree to resolve the issue or the statutory inspection agency can make a ruling. 7.1 Labeling
The product packaging should indicate: product name, manufacturer name, trademark, batch number, net weight, expiration date and product standard number. If the ordering unit has special requirements, it can be negotiated with the manufacturer. 7.2 Packaging
The product should be packed in a clean and odorless zinc barrel. All products should be accompanied by a quality certificate 10

, including: manufacturer name, product name, production date, batch number, trademark, net weight and proof that the product quality conforms to this standard.
During transportation, it should be loaded and unloaded gently to prevent sun exposure, and should comply with the regulations of relevant departments 7. 4 Storage
The product should be stored in a dry, ventilated, cool warehouse to prevent contamination by foreign gases and away from fire sources. .5 If the storage conditions are met, the packaging is intact and not sealed, the shelf life of the product is one year. 41 Working conditions
