Why are vegetable canneries often built near growing areas?

Vegetable canneries are often built near growing areas to minimize the time between harvest and processing. Because fresh vegetables are living organisms, they undergo continuous life processes after harvest—such as water loss, chemical changes, and decay—that lead to quality deterioration and nutrient loss.12

By processing vegetables immediately after they are harvested, canneries can capture the produce at its peak quality and nutritional state before these postharvest losses occur. This proximity is essential because transporting fresh produce over long distances often results in significant degradation of color, texture, flavor, and vitamin content. Consequently, processing near the source of production allows for a final product that can be nutritionally superior to fresh vegetables that have been subjected to prolonged storage and transportation.21
