Post Harvest Technology

Post Harvest technology refers to the scientific methods and processes used to handle, store and process crops after they are harvested. These practices are important for maintaining the nutritional value and shelf life of produce, ultimately reducing food waste of the food supply chain. One-third of the food produced globally is lost or wasted with much of the waste occurring after harvest.

Why incorporating post-harvest strategies is important?

Fruits and vegetables have a limited shelf life once harvested. Proper handling and storage techniques such as refrigeration, controlled atmosphere storage and chemical treatments can slow down the ripening process, allowing produce to stay fresh longer. By preventing spoilage, post-harvest technology helps reduce food waste. As fruits and vegetables age, they lose essential nutrients. Technologies like proper packaging and optimized storage conditions help preserve their nutritional content, ensuring consumers receive high-quality food. Post-harvest processes often include treatments to eliminate harmful pathogens and pests, ensuring that the produce reaching consumers is safe for consumption.

How Can Crops Benefit from Post-Harvest Technology?

Handling crops with care post-harvest through careful harvesting, sorting and packing minimises physical damage which can lead to faster spoilage. Some vegetables and fruits require specific moisture levels to maintain their freshness. Techniques such as waxing or packaging in humidity-controlled environments help retain moisture and prolonging freshness. Refrigeration is one of the most crucial aspects of post-harvest technology. Maintaining low temperatures slows down the biological processes that cause food decay. However, each crop has an optimal storage temperature that needs to be monitored to prevent cold injury. Adjusting the oxygen, carbon dioxide and nitrogen levels in the storage environment can help slow down the respiration of fruits and vegetables, delaying ripening and decay.

Conclusion

Post-harvest technology is a vital aspect of modern agriculture, significantly impacting the quality and availability of crops. In the coming years, we can expect more smart solutions aimed at reducing food waste and improving the sustainability of the food supply chain. As global populations grow, optimizing post-harvest technology will play a critical role in feeding the world efficiently and responsibly.
