there is a huge industry revolving around the chemistry of food ... all food ... even ice cream and also with the scents and smells of products.
i love the scent of orange pledge (on my basses) and the smell of swiffer pads.
peoples ever changing tastes and desire to try new things has chemists in this industry trying all different kinds of chemical combinations that they can use to stimulate people to buy a companies product over another (without poisoning them) .
cleaning products,
food,
deoderants,
candles,
candy,
laundy soap ............
... but i can understand why you would want to work mainly with ice cream.
