Definition of food processing ⚫ A simple definition of food processing is the conversion of raw materials or ingredients into a consumer food product. ⚫ “Commercial food processing" is defined as that branch of manufacturing that starts with raw animal, vegetable, or marine materials and transforms them into intermediate foodstuffs or edible products through the application of labor, machinery, energy, and scientific knowledge

HISTORY OF FOOD PROCESSING ⚫ Some of the earliest forms of food processing resulted in dry food products. These references to various types of commodities date to very early times and the use of thermal energy from the sun to evaporate water from the product and establish a stable and safe dry product

⚫ The history of chilled and/or refrigerated foods dates to very early times as well. The first references are to the use of natural ice used to preserve food products for extended periods of time. A patent for use of a commercial refrigeration process for fish was registered in l842

⚫ The use of high temperature to produce safe food products dates to the 1790s in France. Napoleon Bonaparte offered a prize to scientists to develop preserved foods for the armies of France. This offer lead to the research of Nicholas Appert and the commercial sterilization of foods. In the 1860s, Louis Pasteur, working with beer and wine, developed the process of pasteurization
