No because often in food commercials they use props like glue for milk in a cereal commercial. they do this to make it look more good to the eye and it’s how you get someone to buy it
No, this is because in ads often the foods are edited with photoshop skills and lighting tricks. In some cases, they use non-edible props to make their food look more appetising. For example, when filming an ad for ice cream, it will most likely melt due to the heat emitted by the lighting in the photoshoot. Therefore, some brands use shaving foam instead! Just like how often models wear makeup or photoshop their body when it comes to the fashion and beauty industry, the same applies to the food industry.
