Post Harvest Technology (PHT) concerns activities between harvest and consumption of fresh horticultural crops.
PHT starts with harvest procedures it ends with consumption. Storage of crops, sorting and grading, packaging and transportation are important PHT activities. PHT comprises three aspects:
Physiology: harvested crops continue life processes such as respiration, ripening and transpiration without supply of water and minerals. Crops deteriorate therefore after harvest. Fresh crops are diverse in structure, composition and physiology. Crops contain 80 till 98% water and are therefore subject to desiccation, mechanical injury and pathological breakdown. Requirements are very different because of this diversity.
Technology: deterioration must be inhibited with technical means. Harvest-, storage –, sorting/grading – and transportation technology are needed to minimize deterioration.
Marketing: movement of crops through marketing channels depends on many conditions... More > like marketing standards.< Less
