Postharvest Nanotechnology for Fresh Horticultural Produce


Book Description

Food scarcity and insecurity is an alarming issue throughout the world. Postharvest loss due to both mechanical damage and microbial spoilage significantly influences the shelf life and hence the availability of agricultural produce. Once initiated, the microbial spoilage can make bulk quantity of a given agricultural product unacceptable for human consumption, and several methods have already been used to try to manage this. Considering the limited success of the available methods, there is increasing interest in exploring nanotechnological methods. These methods are being considered for both the development of various platforms for antimicrobial/barrier packaging applications that minimize the contact of agricultural produce with the external environment, and also for design sensors to ensure food safety and quality. The impact of various nano-systems developed through material engineering on the shelf-life enhancement and storage of fresh horticultural produce will have revolutionary effects on post-harvest management in the coming years. Hence, Postharvest Nanotechnology for Fresh Horticultural Produce has been edited to advance understanding of material development, intelligent selection of nanomaterials to ensure the nontoxic nature, and future perspectives of nanotechnology on postharvest produce.
