The process involves the use of bacteria, fungi, and yeasts to convert the carbohydrates and naturally present sugars of food into acids, gases, or alcohol. The process of fermentation improves the taste of foods, extends the shelf life of and improves the nutrient content of foods.<\/span><\/p>\n<h2>What Are Fermented Foods?<\/h2>\n<p><span style=\"font-weight: 400;\">To define\u00a0fermented foods,\u00a0some of the science involved must be explained.\u00a0Fermentation\u00a0is a naturally occurring process that involves a collection of various microorganisms. In the process of fermentation, the microorganisms will convert sugars and carbohydrates into a simpler form. The end products of the fermentation process can include lactose and alcohol, and the conversion of the carbohydrates in the food system can involve the process of:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Improving the taste of food<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Improving the shelf life of food<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Improving the ease of digestion of food<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Promotion of beneficial microorganisms<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Unlike modern <\/span><a href=\"https:\/\/www.ficsi.in\/blog\/common-food-preservation-techniques\/\"><span style=\"font-weight: 400;\">techniques of food preservation<\/span><\/a><span style=\"font-weight: 400;\">, fermentation is a biological approach to food preservation.<\/span><\/p>\n<h2>How Fermentation Works<\/h2>\n<p><span style=\"font-weight: 400;\">Fermentation uses microorganisms, particularly:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lactic acid bacteria<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Yeast<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Molds<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">These tiny organisms, also known as microbes, eat sugars and create lactic acid, ethanol, and carbon dioxide as by-products. The lactic acid created during fermentation increases the acidity and prevents the growth of many spoiling bacteria, meaning that fermentation food preservation is one of the oldest and safest methods of preserving food.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In food processing, especially in the dairy, bakery and beverage sectors, the\u00a0food processing industry in India\u00a0also relies on controlled fermentation.<\/span><\/p>\n<h2>Types of Fermented Foods<\/h2>\n<p><span style=\"font-weight: 400;\">Due to the microorganisms and the food that is processed, there are many\u00a0types of fermented foods.<\/span><\/p>\n<h3>1.\u00a0 Lactic Acid Fermented Foods<\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Yogurt<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Sauerkraut<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Kimchi<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pickles<\/span><\/li>\n<\/ul>\n<h3>2.\u00a0 Yeast-Fermented Foods<\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Bread<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Beer<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Wine<\/span><\/li>\n<\/ul>\n<h3>3.
