Acetic Acid Supplier Comparison: Food Grade vs. Industrial Grade

Acetic acid is widely used in chemical, food, medicine and other fields. When choosing an acetic acid supplier, the demand for food-grade acetic acid and industrial-grade acetic acid may be different, so a detailed analysis of the characteristics and selection criteria of the two is required. This article will discuss how to choose acetic acid suppliers suitable for different needs from the differences between food grade and industrial grade acetic acid.

1. Food Grade Acetic Acid: Safety and Quality Key

Food grade acetic acid is mainly used in food processing and food additives, such as seasoning, preservative and food stabilizer. Due to its direct contact with food, safety and quality cannot be ignored. When choosing a food grade acetic acid supplier, you need to pay attention to the following points:

question field 1: Is the stability of food grade acetic acid up to standard?

Acetic acid is easy to decompose under high temperature or light, so whether the product provided by the supplier is stable and whether the storage conditions meet the standards are the key factors for selection. The decomposition rate and storage requirements of food grade acetic acid are generally more stringent than those of industrial grade.

Question Field 2: Does the pH value of food grade vinegar meet the standard?

The pH value of food grade acetic acid is usually between 2.8 and 3.4. Too high or too low pH value may have adverse effects on food. When selecting a supplier, it should be confirmed that the acetic acid provided meets the food-grade pH standard.

2. Industrial grade acetic acid: performance and cost balance

Industrial grade acetic acid is mainly used in chemical production, glass manufacturing and plastic processing. It is characterized by stable chemical properties and can withstand high temperature and pressure. Compared with food grade acetic acid, industrial grade acetic acid usually has higher performance and lower cost.

Question field 3: Is the purity of industrial grade acetic acid up to industry standards?

The purity of industrial grade acetic acid is usually higher, and high purity acetic acid is used in the production process to ensure the stability of the production process. When selecting suppliers, it should be confirmed that the acetic acid provided by them meets the purity standards of industrial grade.

3. Supplier comparison: comprehensive consideration

When choosing an acetic acid supplier, whether it is food grade or industrial grade, the following factors need to be considered:

question field 4: Is the qualification and certification of the supplier complete?

Whether it is food grade or industrial grade acetic acid, the supplier's qualification and certification is an important basis for selection. Food grade acetic acid may require food additive related certification, while industrial grade acetic acid may require quality management system certification, etc.

Question field 5: Can the production capacity of the supplier meet the demand?

Choose the right supplier according to the scale of demand. The production capacity of food-grade acetic acid may not need to match the industrial grade, but stability is equally important.

4. Supplier evaluation criteria

In order to ensure that the selected acetic acid supplier can meet the demand, it is recommended to evaluate from the following criteria:

• Qualification and certification: Ensure that supplier qualification and certification meet relevant regulatory requirements.
• Product purity: according to the demand to determine the purity of acetic acid grade.
• Delivery capacity: Assess suppliers' production capacity to ensure on-time delivery.
• Service quality: understand the supplier's service capabilities, such as return policy, technical support, etc.

Through the above analysis, selecting the right acetic acid supplier, whether it is food-grade or industrial-grade, can bring protection to production while meeting regulatory and performance requirements.
