Which of the following indicates spoilage in food?

The indication of spoilage in food is best represented by off odors, changes in color, and unusual textures. These signs are clear indicators of microbial activity or chemical changes in food that can occur over time, especially if the food has not been stored properly or is past its expiration date.

Off odors can suggest the presence of spoilage bacteria or the breakdown of food components, leading to unwanted smells. Changes in color may indicate that the food is no longer fresh or has undergone oxidation, which could affect its safety for consumption. Unusual textures, such as a slimy or mushy feel, can be a sign that the food has begun to decompose or that harmful microorganisms are present.

In contrast, bright colors and pleasant scents would typically suggest freshness rather than spoilage. Soft consistency alone, especially if combined with freezing temperatures, could imply appropriate ripeness or simply that the food has been chilled, which doesn't necessarily indicate spoilage. Standard packaging and appearance suggest that food is being presented properly, but they do not provide information about the food's condition. Therefore, the signs of spoilage are specifically linked to off odors, color changes, and unusual textures.
