Post-harvest Management and Value Addition are critical aspects of the agricultural supply chain, particularly for fruits and vegetables, which are highly perishable commodities. After harvesting, the quality and marketability of these products can significantly decline if not handled properly. Effective post-harvest management practices are essential to minimize losses, maintain quality, and enhance the economic value of produce.
Globally, a substantial percentage of fruits and vegetables are lost due to inadequate handling, storage, and transportation methods. This not only affects the income of farmers and producers but also contributes to food insecurity and waste. Therefore, implementing efficient post-harvest strategies is vital for ensuring that fresh produce reaches consumers in optimal condition.
Value addition refers to the processes that enhance the economic value of raw agricultural products. This can include various methods such as processing, packaging, and marketing, which transform fresh fruits and vegetables into more desirable and longer-lasting products. By adding value, producers can increase their profit margins, create new market opportunities, and meet the evolving demands of consumers for convenience and quality.
