Question

What plays a major role to identify stale food?

Answer 1

smell and colour are the major role to identify stale food

Answer 2

When we think of food going stale, we typically think of products such as bread. You might think that bread starts to stale days after it is made. But the process of staling actually begins as soon as the loaf leaves the oven and begins to cool. How quickly bread goes stale depends on what ingredients are in it, how it was baked, and the storage conditions.
