Chicken nuggets are a kind of meat food invented by Robert Baker, a professor of food science at Cornell University in the United States in the 1950s, and were directly published as academic works without applying for a patent. Robert Baker pre-cooked the chicken breast paste and divided it into thumb-sized pieces, then coated it with bread crumbs or corn flakes and quickly fried it to make the first batch of chicken nuggets in history. Baker’s food method invention not only allows chicken nuggets to present a variety of appearances, but also allows chicken nuggets to be widely sold in the food market as a frozen food.
One of McDonald’s food products, Chicken McNuggets, was developed and patented by Tyson Foods in 1979, and officially began selling the food in 1980. According to a 2003 statistic, McDonald’s sells nearly 4.8 million servings of Chicken McNuggets per year.
