Post-harvest Management and Value Addition of Fruits and Vegetables

HORT 381 is a post-harvest management and value-addition course that explains how fruits and vegetables are handled, stored, processed, preserved, packaged, and evaluated after harvest.

Post-harvest management is important because fruits and vegetables are highly perishable, and poor handling after harvest can cause major losses in quantity, quality, shelf life, and market value.

Post-harvest losses are reductions in the quantity or quality of produce that happen after harvest due to damage, spoilage, poor storage, improper handling, physiological changes, or inadequate processing.

Maturity is the stage at which produce is ready for harvest or further development, while ripening refers to the physical, chemical, and sensory changes that make many fruits ready to eat.

Respiration and storage conditions are important because temperature, humidity, gases, and handling influence how fast produce deteriorates, loses water, softens, spoils, or maintains market quality.

Value addition means converting raw produce into higher-value products such as jam, jelly, juice, squash, dried products, candy, or tomato products to improve shelf life, convenience, and returns.

Packaging and cold storage are important because they help protect produce from physical injury, moisture loss, contamination, and rapid spoilage during storage, transport, and marketing.

They study these because horticultural value chains depend not only on fresh produce marketing but also on preservation and processing methods that reduce waste and create stable marketable products.
