The defrosting cycle should be set to accomplish the process automatically. 5. Light and other factors: Exposure of potato tubers to light in grocery stores can synthesize glycoalkaloids (solanine and chaconine), which are toxic to humans. Likewise, other factors such as herbicides, fungicides, pesticides, and growth regulators may affect the produce and may have harmful effects on humans. 1 Storage Operations The increase of fruit and vegetable production, owing to large acreage and high-yielding cultivars, requires sufficient storage space.

Air movement: Air movement must be sufficient to remove respiration heat. Because it is essential that all parts of the room are subject to a uniform flow of air, proper placement of blowers or ducts and stacking of fruits and vegetables will permit free air flow. The successful operation of a large refrigeration system requires an efficient control system. Microcomputers are presently used to allow precise controls for large warehouse refrigeration systems. The defrosting cycle should be set to accomplish the process automatically.

Cellars are provided with heaters and dry atmospheres during winter months. 4°C). Where snow is prevalent, a good cellar will provide satisfactory storage for hard vegetables and fruits. Above ground warehouses may be used to store produce. In cold weather, the produce is covered with blankets to protect from cold temperatures. Ventilation is essential for good storage. Potatoes, onions, garlic bulbs, crucifer, leafy vegetables, and fruits are stored successfully. This storage structure has several advantages over other types.
