What primarily drove the initial voluntary adoption of dating food products starting around the 1930s?
Answer
Manufacturers trying to signal freshness, particularly after vitamin fortification
The practice of dating food began evolving voluntarily around the 1930s, not due to a government rule, but primarily as a quality control mechanism initiated by manufacturers themselves. A key driver for this early adoption was the addition of synthetic vitamins to certain staples, such as milk. Manufacturers needed a method to assure consumers that the fortified product still retained the advertised peak nutritional value, making the date a marker of potency rather than an expiration deadline for safety.
