There are many types of fruit juices; **there are at least 9 types of fruit juices (as of 2006), and different standards apply to each type.** For fruit juices, tests are generally conducted on sugar content, acidity, pH level, as well as for the presence of bacteria and mold. It seems that different products have different requirements. **Standard information can usually be found online; once you start working at the company, you will quickly become aware of the specific requirements and relevant standard documents, which is likely to be more practical.** For analysis, it’s sufficient to pay close and careful attention; just do the work with humility, modesty, and diligence, hehe
