Nugget de poulet
Résumé
A chicken nugget is a food product consisting of a small piece of deboned chicken meat that is breaded or battered, then deep-fried or baked. Invented in the 1950s, chicken nuggets have become a very popular fast food restaurant item, as well as widely sold frozen for home use.
The chicken nugget was invented in the 1950s by Robert C. Baker, a food science professor at Cornell University, and published as unpatented academic work. This bite-sized piece of chicken, coated in batter and then deep fried, was called the "Chicken Crispie" by Baker and his associates. Two problems the meat industry was facing at the time were being able to clump ground meat without a skin and producing a batter coating that could be both deep fried and frozen without becoming detached. Baker's innovations solved these problems and made it possible to form chicken nuggets in any shape by first coating the meat in vinegar, salt, grains, and milk powder to make it hold together and then using an egg and grain based batter that could be fried as well as frozen.
Chicken nuggets are generally regarded as a fatty, unhealthy food. A study published in the American Journal of Medicine analyzed the composition of chicken nuggets from two American fast food chains. It found that less than half of the material was skeletal muscle, with fat occurring in an equal or greater proportion. Other components included epithelial tissue, bone, nervous tissue and connective tissue. The authors concluded that "Chicken nuggets are mostly fat, and their name is a misnomer."
The processing required for making chicken nuggets begins with deboning. The chicken is cut and shaped to the correct size. This is done either manually, or by a series of automatic blades, or by a process called grinding (a method of deboning in which the softer parts of the chicken carcass are forced through a mesh, leaving behind the more solid pieces, resulting in a meat paste. If used, this paste is then shaped before battering).
