Food preservation

Food preservation prevents the growth of microorganisms (such as yeasts) or other microorganisms (although some methods work by introducing benign bacteria or fungi to the food) and slowing the oxidation of fats that cause rancidity Food preservation may also include processes that inhibit visual deterioration such as the enzymatic browning reaction in apples after they are cut during food

Food Preservation: Canning Freezing And Drying

Jul 31 2016Salting is a sub category of the drying method The main difference here is that salt is added to products mainly meat and fish to draw out moisture This lowers the bacteria content and makes food adaptable for later use Adding salt to animal protein turns it a bit leathery Popular foods made in this tradition are beef jerky and dry salted cod Food Preservation Methods: Canning
