Food-extrinsic factors are influences on how people perceive and evaluate a food item that come from outside the food itself. Food-extrinsic factors include food packaging, labelling, branding, price of the food item, cultural associations and meaning of the food item, background music, temperature, the overall context or the environment in which the food is consumed, and many others (Wang et al., 2019).
