How the unpatented research of a brilliant food sciences professor may have helped make the fast-food icon possible.
Earlier this week, Fred Turner, the influential former McDonald's CEO who helped turn his company into the globally loved, burger-flipping colossus it is today, died at the age of 80. We can thank Turner for such fast food icons as the Egg McMuffin, the drive-through window, and the Happy Meal. But for those of us who happen to care about patent law, there's one part of his legacy that's particularly fascinating: the Chicken McNugget.
Until fairly recently, it was conventional wisdom that McDonald's had invented the entire devilishly addictive concept of the chicken nugget in the late 1970's as American diners began cutting down on the red meat — and hence, hamburgers — in their diets and started turning to poultry. But a few weeks back, Maryn McKenna published a wonderful piece of corrective history in Slate that traced the origin of the spongy fried chicken chunks back to the work of Cornell food sciences professor Robert Baker. Baker was brilliant researcher devoted to expanding the then-paltry market for chicken and egg products, engineering technically advanced recipes for hot dogs, canned hash, frozen meatloaf, and other gustatory marvels in his university lab. In the early 1960s, he perfected a process for boneless fried "chicken sticks." Here's McKenna's description:
Baker's prototype nugget, developed with student Joseph Marshall, mastered two food-engineering challenges: keeping ground meat together without putting a skin around it, and keeping batter attached to the meat despite the shrinkage caused by freezing and the explosive heat of frying. They solved the first problem by grinding raw chicken with salt and vinegar to draw out moisture, and then adding a binder of powdered milk and pulverized grains. They solved the second by shaping the sticks, freezing them, coating them in an eggy batter and cornflake crumbs, and then freezing them a second time to -10 degrees. With trial and error, the sticks stayed intact. Baker, Marshall, and three other colleagues came up with an attractive box, designed a dummy label, and made enough of the sticks to sell them for 26 weeks in five local supermarkets. In the first 6 weeks, they sold 200 boxes per week.
Were Baker working today, you could be sure that he would have had a patent application submitted well before the first box was shipped. But the professor never really attempted to cash in on his discoveries. Instead, he published his research in regular bulletins that he then sent out to hundreds of companies around the country. As McKenna notes, Baker also moonlighted as a corporate consultant, and his grad students students spread his know-how as they landed jobs throughout the food industry.
