The evaluation process of container quality involves several aspects. Firstly, a physical inspection is conducted which includes examining the container's appearance, weight, vacuum degree, tightness, and inner wall condition. Additionally, a chemical test is carried out to determine various parameters such as pH value, soluble solids, juice concentration, acidity, heavy metals, food nutrients, and residual pesticides. Furthermore, a sensory inspection is performed to assess the organization, shape, color, taste, and aroma of the contents. Lastly, a microbiological inspection is conducted to detect the presence of pathogenic bacteria, spoilage microorganisms, assess commercial sterility, and determine the mold count. By following these inspection protocols, a comprehensive evaluation of container quality can be achieved.
