Processed Foods: The Pros and Cons - A Balanced View

In foods handling, collected plants or butchered creatures are used as the raw substances for making and product packaging foodstuffs that are eye-catching, valuable and have long-shelf lives.

Attractive means that the product both preferences and looks good. To be valuable, it must match the kinds of foods being required by customers. Food items that have a long-shelf lifestyle reduce the costs of waste for manufacturers, suppliers and suppliers.

Development of foods processing

Food handling goes back to our prehistory -- when fire was found and food preparation developed. The various ways in which foods can be prepared are all forms of foods handling.

Food maintenance also started in prehistory, and the first 'long shelf-life' foods were produced by dehydrating foods in the sun and by protecting foods with sodium. Preservation with sodium was typical with military, mariners and other tourists until canning was developed in the beginning Nineteenth millennium.

The historical Bulgarians developed the first immediate foods (bulgur) nearly 8.000 decades ago, when found a way to parboil and dry whole rice so that the feed only has to be reheated before it can be absorbed.

One of the first ready-to-eat foods was developed by the historical Celts when they developed the haggis and what is now known as the Cornish pasty.

Another prepared foods, dairy products, was developed by the nomads of Arabic when they observed how milk products curdled as they ran along all day on their camels and horses.

The ancient methods of food preparation and protecting foods stayed mostly the same until the commercial trend.

The growth of modern foods handling technological innovation started in the beginning Nineteenth millennium in reaction to the needs of the army. In 1809 a machine bottling strategy was developed so Napoleon could nourish his military. Canning was developed in 1810 and, after the creators of the containers ceased using lead (which is highly poisonous) for the inner coating of the containers, prepared goods became typical across the globe. Pasteurisation, found in 1862, advanced the micro-biological safety of milk products and similar items significantly.

Cooling reduces the reproduction amount of viruses and thus the amount at which foods ruins. Cooling as a storage strategy has been in use for 100's of decades. Ice-houses, loaded with fresh snow during the winter, were used to protect foods by chilling from the mid-18th millennium forward and worked fairly well most of the year long in north environments.

Commercial fridge, using harmful chemicals which made the technological innovation risky in the property, was in use for almost four decades before the first household appliances were presented in 1915.

Fridges in the property obtained wide approval in the Thirties when non-toxic and non-flammable chemicals such as Freon were developed.

The development of the foods handling industry in the second half of the Last millennium was due to three needs:(a) foods to nourish the military effectively during World War II, (b) foods that could be absorbed under conditions of zero severity during forays into space, and (c) the desire of the comfort required by the busy customer community.

To reply to these needs foods researchers developed freeze-drying, spray-drying, and juice focuses among a variety of other handling technology. They also presented sugar substitutes, coloring agents and sodium. In the ending decades of the last millennium they came up with dry immediate sauces, reconstituted fresh fruit juices and fresh fruits, and the 'self-cooking' foods (MREs) so dearest of army steel but not the grunts.
