Which of the following is NOT a sign of food spoilage?

The indication that fresh appearance is not a sign of food spoilage is rooted in the understanding of how food remains safe and visually appealing. A fresh appearance typically means that the food item looks wholesome and is free from any spoilage indicators. This includes vibrant colors, an intact surface, and no visible mold or significant blemishes.

In contrast, off smells, changes in color, and unusual texture are all indicators that spoilage may have begun. For example, a sour or rancid odor suggests bacterial activity or fermentation, changes in color can indicate chemical reactions or the presence of mold, and an unusual texture may indicate that the food is breaking down or has been compromised in some way. These signs serve as warnings that the food may not be safe to consume, while a fresh appearance suggests that the food is still in a good state.
