    ​Despite the remarkable progress made in increasing food production worldwide, approximately half of the population in the developing countries does not have access to adequate food supplies; thus the food security problem is worsening.
    There are many reasons for this, one of which is food losses occurring throughout the supply chain from production, post-harvest, processing and marketing.
    In its recent report “Global food losses and food waste”, the FAO suggests that roughly one-third of food production for human consumption is lost or wasted globally, which amounts of about 1.3 billion tons per year.
    Evidence suggests that these losses tend to be highest in those countries where the need for food is greatest.
    Pre-harvest conditions and events in the fields such as cultivar, soil type, fertilization and irrigation practices, weather conditions, pest control programs etc. have a significant influence on achievement of the best potential postharvest quality and shelf life of fresh fruits and vegetables.
    Plants or plant parts continue to function metabolically after harvest and are subjected to physiological and pathological deterioration and loss. “Loss” means any change in the quality of the food that prevents it from being consumed by people. Postharvest loss in fresh fruits and vegetables is estimated at 5-25% in developed countries and 20-50% in developing countries.
    Causes of this loss are varied with microbiological, mechanical and physiological factors being the main cause in perishable crops. Other causes are in-adequate harvesting, packaging, handling skills and refrigerated storage, as well as inadequate transportation.
    Storage and shelf life are defined as the period from harvest to consumption, while a food product remains safe and wholesome. There is a wide range of postharvest technologies that can be adopted to reduce losses throughout the process from field to fork. Both quantitative and qualitative food losses of extremely variable magnitude occur at all stages in the post-harvest system from harvesting, through handling, storage, processing and marketing to final delivery to the consumer.
    Appropriate storage can minimize moisture loss, slow down respiration rate and inhibit development of decay-causing pathogens. Wilting, re-growth, ripening, senescence and decay can be postponed. Temperature is the most important determination of fresh produce deterioration rate. An important supplement to temperature and relative humidity management is the use of controlled atmosphere (CA) or modified atmosphere (MA) and other technologies.
    Postharvest loss results not only in the loss of the actual crop, but also have an impact on the environment, resources, labor needed to produce the crop and livelihood of individuals involved in the production process. The implementation of appropriate storage and postharvest techniques will add value to the produce and will increase the farmer’s income.
    Aims
    To understand the Physiological, pathological & environmental factors involved in the deterioration of fresh agricultural produce. To learn postharvest technologies and best practices associated with the postharvest handling of fresh fruits and vegetables, to assist in the delay of senescence, reduce loss and maintain the best possible quality of the produce. To initiate research, teaching and transfer knowledge to extension workers and farmers.
    Main Subjects
    Physiological and pathological factors affecting storage and shelf life; Cause and site of loss; Standardization and inspection of fresh produce; Quality factors and analysis; Prolonging shelf life; Post-harvest technologies.
    Application
    Application Requirements
    This course is designed for research and extension workers, quality control personnel in the produce industry, and business, government or academic professionals interested in current advances in the postharvest technology of fruits, vegetables & horticultural crops.
    It is particularly of interest to technical professionals responsible for quality assurance, research and extension activities related to fresh produce quality, safety and marketability under the aegis of national or international organizations, institutions, universities, research institutes, civil society and the private sector. Course participants must have a relevant academic degree and at least three (3) years of practical work experience in related fields. A very good command of the English language is essential.
