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

The presence of a strong fragrance is not typically considered a sign of food spoilage. While food spoilage often leads to off odors, unusual textures, or discoloration, a strong fragrance can actually indicate that the food is fresh or has been well-prepared, particularly in certain contexts, such as with spices and herbs.

On the other hand, unusual textures in food can signify that it is past its prime, as spoilage often alters the physical structure of food. Off odors are one of the most common indicators of spoilage, as they arise from the breakdown of food components and the development of bacteria. Discoloration is also a common sign of spoilage, as it can indicate how food has reacted to time and environmental conditions.

Therefore, identifying strong fragrance as a non-indicator of spoilage can help one distinguish between food that is still safe and good to eat versus that which has degraded in quality.
