Zhang, Wen-Qing;Yu, Zhong-Na;Ho, Harvey;Wang, Jun;Wang, Yu-Tao;Fan, Rong-Bo;Han, Rong-Wei published 《Analysis of veterinary drug residues in pasteurized milk samples in Chinese milk bars》. The research results were published in《Journal of Food Protection》 in 2020.COA of Formula: C15H28O2 The article conveys some information:
The objective of this study was to investigate the safety of PM from a total of 182 PM samples collected from milk bars from 10 provincial capital cities and to analyze the residues of seven classes of 61 veterinary drugs. First, the chem. components were screened with test kits, and then the pos. samples were further confirmed by ultraperformance liquid chromatog.-tandem mass spectrometry. The results showed that 15 (8.24%) samples were screened pos. for veterinary drugs, and six drugs in 11 (6.04%) samples were confirmed. The veterinary drugs detected were penicillin G (2.20%), tetracycline (1.10%), tylosin (1.10%), amoxicillin (0.55%), oxytetracycline (0.55%), and gentamicin (0.55%), with maximum residue levels of 3.4, 11.9, 28.2, 3.0, 26.9, and 63.5μg kg-1, resp. Veterinary drug residues were detected as pos. in 7 of 10 cities, with the highest detection rate as 14.29% in Urumqi. No pos. samples were found in the cities of Nanjing, Tianjin, and Nanning. All detected drug levels were far below the maximum residue levels regulated by China, the European Union, and the Codex Alimentarius Commission. This suggests that the overall veterinary drug residues in PM in milk bars reached the safety code of the country. However, potential risks still exist, and continuous attention should be paid to guarantee the safety of this milk product in the future.Oxacyclohexadecan-2-one (cas: 106-02-5) were involved in the experimental procedure.
Oxacyclohexadecan-2-one(cas:106-02-5) is a natural product found in Lonicera japonica and Angelica archangelica.COA of Formula: C15H28O2 It is a macrocyclic lactone that can be used as a flavoring agent and fragrance ingredient due to its musk flavor/odor.
