The Food That Built America (2019)

A scientist and businessman team up to develop a Vitamin C rich war ration for the troops fighting in World War 2, which unexpectedly leads to the development of a frozen concentrated orange juice that tastes great and allows for the widespread distribution of OJ for the first time in history. Soon after, a fruit salesman develops a process of flash pasteurizing fresh orange juice that turns the fledgling industry on its head. The two companies will go on to battle it out for domination.
