Article shared by: Food preservation has the following advantages: 1. Temperature, pH, air, nutrients, and presence of different chemicals are the major factors for food spoilage [9]. Even foods traditionally thought of as salt-preserved foods don't. Ramaswamy HS, Tung MA. 2016;18(1):307. In practice, freezing process is often referred to chilling, when cooling is conducted at <15C [90]. As mentioned in our Thursday evening dilemma, preservatives allow us to keep food safe much longer. One of the major revolutionary inventions of human civilization was acquiring the knowledge to preserve foods as it was the precondition to man to settle down in one place and to develop a society. As a result, the number of industry enterprises and workers are forecast to grow at annualized rates of 2.2 and 1.6%, respectively, till 2017 [145, 146]. The solutions come in different formulas and salt concentrations depending on what the organisms need to grow.
