Pickling involves using a lot of acid, usually vinegar, to stop the food from spoiling. Vegetables such as eggplant, carrots, cauliflower, tomato, bitter gourd, green tamarind, ginger, garlic, onion, and citron are also occasionally used. Due to the composition, size, and physicochemical properties of eggs (eggs yolks have a high fat and protein content of 32.5 and 17.5%, respectively) (Potter and Hotchkiss, 1998), pickled eggs pose unique challenges to quick and complete acidification and, therefore, proper preservation (Sullivan et al., 2013; Acosta et al., 2014). Pickling was a common method of preserving a large variety of foods like fish throughout the archipelago before the advent of refrigeration, but its popularity is now confined to vegetables and fruits.
