  • Thawed ketchup shouldn’t be refrozen since it could lose its texture and consistency.
  • Remember that ketchup can alter in texture and consistency when frozen, so it’s better to use it as a condiment or in cooked dishes rather than as a stand-alone dip.
  • If you aren’t using the thawed ketchup right away, make sure to keep it carefully in the refrigerator.
  • Use clean, thoroughly sanitized containers when storing, freezing, or thawing ketchup.
  • Ketchup that has been defrosted should be thrown out if it smells bad or seems discolored.

The Integrated Product Policy framework and a tomato ketchup chain have been studied as concrete examples. The findings of the study are presented in this document. Following the identification and analysis of the relevant policy measures, a collection of environmental indicators has been suggested, and their application and significance in the formulation of policy are discussed.
