What is a shelf-life extending agent？

[Close]

  • A sanitizer, antioxidant, and preservative are used to maintain the quality of food. As specified in the regulation in regard to food labeling, an antioxidant and preservative are indicated with the application name as “preservative, etc.” The use of many of these agents is restricted so they are not available to some food.
  • A shelf-life extending agent, indicated only with its name (sodium acetate), functions like these agents, giving slightly moderate effects. It is highly safe and its use is not restricted.
  • Sodium acetate can prevent bacteria cultivation in a wide range of acidic region. It also functions as a buffer as well. When used to add sour taste to food, acetic acid is generally selected, but combination of sodium acetate and acetic acid can make the taste mild.
