Moreover, if additives cause substantial reduction in nutrition, then their uses are also unaffiliated [131]. Shorter freezing period impedes the diffusion of salts and prevents decomposition of foods during freezing. Your privacy choices/Manage cookies we use in the preference centre. Artificial preservatives may act as antioxidants, make food more acidic, reduce the moisture level of food, slow down the ripening process and prevent the growth of microorganisms, all of which help the food last longer. Food preservation is defined as the processes or techniques undertaken in order to maintain internal and external factors which may cause food spoilage. It can increase the shelf life of food items to a large extent; as an example, UHT pasteurization process can extend the shelf life of liquid milk from 19 to 90days, whereas combined UHT processing and aseptic packaging extend shelf life to six months or more. Processing parameters Different types of foods are processed using PEF process. Rapid globalization and industrialization are the major contributing factors for the progress of food processing industries in different countries. This is beneficial in 2 ways. Since these kind of food items fall short of nutritional values, they become the cause of these deadly diseases that slowly kills a person. These exchangers are not very flexible to withstand production capacity alteration, and their use is only limited to low viscous foods.

You then wont need to buy food stuffs every time you need some. More Shopping at the Grocery Store. All cell deaths occur due to the disruption of cell membrane function and electroporation [29]. In this method, the moisture content is lowered to the point where the activities of these microorganisms are inhibited [29, 50]. Chilling retards the growth of microorganisms and prevents post-harvest metabolic activities of intact plant tissues and post-slaughter metabolic activities of animal tissues. 2010;47(6):66873.
