The primitive stage of food spoilage can be detected by color, smell, flavor, texture, or food. Some functional compounds like vitamin C, thiamin, protein, and lipid are also lost because of drying [54,55,56]. This method involves decomposition of carbohydrates with the action of microorganisms and/or the enzymes [113]. The released volatile fatty acids have a stiff malodor and taste; therefore, hydrolytic rancidity is extremely noticeable in fats, such as butter [43].
