kill step

(名詞) 食物烹飪過程中的高溫殺菌處理。

Threatened with a federal shutdown, the pie maker, ConAgra Foods, began spot-checking the vegetables for pathogens, but could not find the culprit. It also tried cooking the vegetables at high temperatures, a strategy the industry calls a “kill step,” to wipe out any lingering microbes. But the vegetables turned to mush in the process.
