• 接收检验
  
  • 当原材料到达工厂时，首先进行接收检验。这包括检查原材料的包装是否完好，标签是否清晰准确。
    

Acceptance inspection
When the raw materials arrive at the factory, the first step is to conduct a receiving inspection. This includes checking whether the packaging of raw materials is intact and whether the labels are clear and accurate.

• 外观检验
  
  • 这是最基本的检验方法。对于不同的原料有不同的外观要求。
  • Appearance inspection
  • This is the most basic testing method. There are different appearance requirements for different raw materials.

• 物理性能检验
  
  • 物理性能包括原料的尺寸、重量、密度、硬度等。
  • Physical performance testing
  • The physical properties include the size, weight, density, hardness, etc. of the raw materials.

微生物检验

• 细菌检测：在食品、药品和化妆品等行业，细菌检测是必不可少的。例如，对牛奶原料进行细菌检测，包括检测大肠杆菌、金黄色葡萄球菌等有害细菌的数量。如果细菌超标，会对消费者的健康造成严重危害。
• 霉菌和酵母菌检测：对于一些含有水分的原料，如木材、谷物等，需要检测霉菌和酵母菌的含量。在造纸工业中，原料木材中的霉菌含量过高可能会影响纸张的质量。
• 病毒检测：在生物制品和部分食品行业（如生鲜产品），病毒检测也越来越受到重视。例如，在利用动物组织生产生物试剂时，需要检测是否存在病毒污染，以确保产品的安全性
  

Microbial testing
Bacterial testing: Bacterial testing is essential in industries such as food, pharmaceuticals, and cosmetics. For example, conducting bacterial testing on milk raw materials, including detecting the number of harmful bacteria such as Escherichia coli and Staphylococcus aureus. If the bacteria exceed the standard, it will cause serious harm to consumers' health.
Mold and yeast testing: For some raw materials containing moisture, such as wood, grains, etc., it is necessary to test the content of mold and yeast. In the paper industry, excessive mold content in raw wood may affect the quality of paper.
Virus testing: In the biopharmaceutical and some food industries (such as fresh produce), virus testing is also receiving increasing attention. For example, when using animal tissue to produce biological reagents, it is necessary to detect the presence of viral contamination to ensure the safety of the product

• 抽样
  
  • 从一批原料中抽取具有代表性的样本是检验的第一步。抽样方法有多种，如简单随机抽样、分层抽样、系统抽样等。抽样数量通常根据原料的批量大小、检验项目的重要性等因素来确定
  • sampling
  • The first step in testing is to extract representative samples from a batch of raw materials. There are various sampling methods, such as simple random sampling, stratified sampling, systematic sampling, etc. The sampling quantity is usually determined based on factors such as the batch size of raw materials and the importance of inspection items.

检验实施

• 根据检验内容和方法，对样本进行物理、化学、微生物等方面的检验。在检验过程中，要严格按照操作规程进行，确保检验结果的准确性。
  

Inspection implementation
According to the inspection content and methods, conduct physical, chemical, microbiological and other inspections on the samples. During the inspection process, it is necessary to strictly follow the operating procedures to ensure the accuracy of the inspection results.
