What is one method to maintain the freshness of candy?

One effective method to maintain the freshness of candy is to limit exposure to light. Light can lead to degradation and fading of ingredients, especially in candies that contain colorants and flavors. By minimizing light exposure, the integrity of the candy's texture and taste can be preserved for a longer period.

Rotating merchandise is certainly an important practice in maintaining stock freshness, as it helps ensure older products are sold first. However, it does not have a direct impact on the actual freshness of the candies themselves once they are displayed.

Using plastic covers can also help protect candies from moisture and contamination but may not be as effective as limiting light exposure. Plastic covers can sometimes trap humidity which could negatively affect candy quality.

Maximizing shelf time may actually work against freshness since longer shelf life can mean that the candy is more likely to degrade over time. The purpose should be to keep the candy for as short of a time as necessary to ensure it is consumed while still fresh. Thus, controlling environmental factors like light exposure is crucial for maintaining the quality of the candy.
