HT-SS stands for Heat Treated-Shelf Stable.

• A. Not Heat Treated-Shelf Stable
• B. Heat Treated-Shelf Secure
• C. Heat Treated-Shelf Stable
• D. Heat Treated-Soft Shelf

Answer: (C)

HT-SS describes foods that have undergone a heat process to destroy pathogens and spoilage organisms and are packaged to be stored safely at room temperature. The first part, “Heat Treated,” indicates the processing step that ensures safety and shelf life. The second part, “Shelf Stable,” means the product can sit on a shelf without refrigeration under proper storage conditions. Therefore, the correct expansion is “Heat Treated-Shelf Stable,” which matches both components of the acronym. The other options either negate the heat treatment, replace a term with an unrelated word, or describe an incorrect shelf condition.
