Pre And Primary Processing -Some Basic Concepts

In the earlier three units, we learnt about the principles and methods of food processing. Certain issues related to production, harvesting and handling of food prior to processing needs to be considered. For instance, how is the raw material (i.e., the food) to be prepared for processing? What are the aspects to be considered while post-harvest handling of fresh foods? What are the primary processing methods used for foods? In this unit, we will focus on these aspects. Production, harvesting, handling and preparation of raw material for processing will be highlighted. All food grains need some kind of processing, say, primary, secondary and tertiary-for bringing them to a palatable state.
