Reducing Post-harvest Losses of Betel (Piper betel L.) Leaves by various Preservation Techniques
Abstract
Due to highly perishable nature, betel leaves undergo quick spoilage due to fungal infections and discoloration during storage and transportation. Post-harvest losses of betel leaves can be prevented if proper preservation techniques are followed. Right from the ancient techniques of solar drying and depetiolation to the modern methods of preservation including modern drying technologies, modifying surrounding atmosphere, advanced packaging technologies, etc., can prove to be beneficial in reducing post-harvest losses of betel leaves. Such wastage may also be reduced by extracting essential oils from the leaves which remains unsold in the market. This essential oil has reported of remarkable medicinal and aromatic properties which indicate a promising industrial future. If a well-coordinated effort by the farmers, traders, scientists, technologists and policy makers are made, it will not only help reduce the post-harvest losses of betel leaves but also boost the national economy and also generate huge employment opportunities for the people.
