Snacks are food that are eaten as a substitute for meals or to compensate the sense of hunger in between meals. As the healthy living is gaining more attention, premium snacks using healthy ingredients and well-being snacks such as low-calorie and low-sodium have been released. Especially, potato chips are one of the most popular snacks. Unlike in the past, where there was only salty flavor, various flavors such as sweet, salty, greasy, and spicy are being introduced and enjoyed.
