It has direct applications to postharvest handling in establishing the storage and transport conditions that best prolong shelf life. An example of the importance of the field to post-harvest handling is the discovery that ripening of fruit can be delayed, and thus their storage prolonged, by preventing fruit tissue respiration.
Post-harvest losses of vegetables and fruits occur at all points in the value chain from production in the field to the food being placed on a plate for consumption. Post-harvest activities include harvesting , handling, storage , processing , packaging , transportation and marketing .
Post-harvest losses occur between harvest and the moment of human consumption. They include on-farm losses, such as when grain is threshed , winnowed , and dried. Other on-farm losses include inadequate harvesting time, climatic conditions, practices applied at harvest and handling, and challenges in marketing produce.
Gleaning is the act of collecting leftover crops in the field after harvest. During harvest, there is food that is left or missed often because it does not meet store standards for uniformity. Sometimes, fields are left because they were not economically profitable to harvest.
A food storage calculator can be used to help determine how much of these staple foods a person would need to store in order to sustain life for one full year. In addition to storing the basic food items many people choose to supplement their food storage with frozen or preserved garden-grown fruits and vegetables and freeze-dried or canned ...
Cost (C) = Cost of harvesting + handling. Hence, Profit = Revenue − Cost. Since the benefit is generated over multiple years, it is necessary to calculate that particular age of harvesting which will generate the maximum revenue. The age of maximum revenue is calculated by discounting for future expected benefits which gives the present value ...
They use hermetic storage technology to reduce loss of post-harvest cowpea (Vigna unguiculata) due to bruchid infestations in West and Central Africa. [3] A PICS bag consists of two layers of polyethylene liners and a layer of woven polypropylene. [4] Each layer is closed separately to create a hermetically sealed container for harvested grain.
The quality of fish and fish products depends on safe and hygienic practices. Outbreaks of fish-borne illnesses are reduced if appropriate practices are followed when handling, manufacturing, refrigerating and transporting fish and fish products. Ensuring standards of quality and safety are high also minimizes the post-harvest losses." [16]
