What Is Hot Fill Processing?

  • Hot-Fill Products must have a pH<4.6 (High Acid)
    • This process uses the heat and acidity of the product to sterilize the product and the bottle.
    • The product is typically heated to between 82° and 88° C (180°-190° F)
    • The product is filled at this temperature into the bottle
      • Special containers and caps are required to maintain the seal and withstand the temperatures)
      • The bottle must be laid on its side to expose the lid to the hot product.
    • The “Hold Time” is done in the bottle and is generally 1-3 minutes.
