Which vegetable is expected to generate the most heat during confined storage?

In the context of confined storage, the heat generated by vegetables is measured in BTUs (British Thermal Units) and relates to the respiration rates of the produce. The correct choice indicates that lima beans produce a significant amount of heat during storage, with a value of 4100 BTU per ton over 6 hours. This high respiration rate suggests that as lima beans breathe, they metabolize sugars and produce heat, which is critical for understanding how to manage the storage environment to prevent spoilage and maintain quality.

Considering the respiration rates provided for the other vegetables, snap beans, asparagus, and cucumbers have comparatively lower BTU values relative to the time frames given. While cucumbers show a high BTU value over 48 hours, the total heat generated per ton over that extended timeframe is still lower than what lima beans can produce over a shorter duration. Therefore, the lima beans exhibit a more intense heat generation, which is crucial for anyone in food storage or handling to be aware of, as it can greatly influence the temperature and quality control measures that need to be taken.
