Which processing method is similar to HTST but uses slightly different equipment and higher temperatures for a shorter time?

Which processing method is similar to HTST but uses slightly different equipment and higher temperatures for a shorter time?

• A. High Heat Short Time
• B. High Temperature Short Time
• C. Ultra Pasteurized
• D. Pasteurization

Answer: (A)

The concept here is a variation of pasteurization that uses higher temperatures for a shorter time, with equipment designed for rapid heating. Ultra Pasteurized fits this description because it raises the heat to about 138°C for a couple of seconds, using specialized equipment to achieve very rapid, intense heating. This achieves the same goal of microbial reduction as HTST but with a different set of processing conditions, often resulting in longer refrigerated shelf life compared with standard pasteurization. The other terms either describe the same HTST process in different words (not a distinct method) or refer to generic pasteurization without specifying the higher temperature-short time combination.
