Application of Various Techniques for Meat Preservation

Abstract

Mahendra Pal and Mridula Devrani

Since the pre-historic times, meat is consumed by humans as part of diet. Meat is an animal flesh that is considered as an excellent source of high biological value protein, zinc, iron, magnesium, selenium, phosphorus, and vitamins. In recent years, global meat production and consumption have increased. The production of meat in the world was estimated at 317.17 million tons in 2016. Meat is very much susceptible to spoilage due to chemical and enzymatic activities.The breakdown of fat, protein, and carbohydrates of meat result in the development of off-odors, off-flavor and slim formation, which make the meat objectionable for the human consumption. Several factors such as moisture, light, microbes, atmospheric oxygen, temperature, and endogenous enzymes influence the freshness and shelf life of meat. Microbes are ubiquitous in distribution and can reach the meat from different sources thus causing its spoilage. Therefore, various technologies are used to preserve the meat in order to inactivate/destroy the microbes, which are implicated in foodborne infections. Canned food stored in cool and dry place can last up to a year. Since preservation of meat by irradiation requires heavy investment, its commercial application is still in its infancy. It is emphasized that preservation of meat is imperative to prevent the occurrence of deteriorative changes brought by microbial, chemical and physical process. Further, well preserved meat can give protection against all hazards for a considerable time.
