Wikipedia entry for John Arbuckle
Improvement in Roasted Coffee
Description:
In 1868, Arbuckle patented a formula for an egg-based glaze that coated coffee beans, protecting them from the air. He went on to form Arbuckle Brothers Co. to sell packaged coffee.

The glazing process kept the coffee fresh longer.
