What Is UHT / HTST Processing

High Temperature Short Time (HTST) and Ultra High Temperature (UHT) are temperature ranges at which you can process your products. HTST processes include pasteurization, high-acid aseptic processing, and hot-filling. Low-acid aseptic processing is a UHT – Ultra High Temperature Pasteurization & Sterilization process. Finally, Extended Shelf Life (ESL) processes are performed at the HTST or Ultra High Temperature Pasteurization (UHT) temperature range, depending on the product. Your product, shelf-life, and storage needs will determine the process and temperature range to best fit your needs.

  • HTST and UHT refer to temperature ranges in which processes are conducted.
  • Common HTST temperature range: 80°-110° C (176°-230°F)
  • Common UHT temperature range: 136°-149° C (277°-300° F)
