A method of production of boneless chicken wings without cutting skin and muscles
Broiler chicken wings including drumettes and winglets, which contain much less meat than do other parts (including leg and breast) of chicken carcass, are commonly served without deboning. However, if deboned, the value of chicken wing may be improved. For example, eating becomes easier with boneless than with bone-in product. Since many consumers like convenient foods, boneless wings may become more popular than bone-in wings, if they are deboned by an inexpensive method. This paper describes a method of removing bones (i.e., humerus from the drumette and radius and ulna from the winglet) to produce boneless wing products.
A common method of deboning involves cutting skin and muscles to separate bone, whereas in this study, deboning was carried out by dislocating articular cartilage attached to the end of bone followed by stripping periosteum (a connective tissue sheath that surrounds the diaphysis, a shaft of bone) (Fig. 1). This is possible in long bones (such as humerus, radius and ulna) of broiler chickens, which are young rapidly growing birds commonly slaughtered at 6 to 8 weeks of age. In these birds, articular cartilage and periosteum tissues are immature and loosely attached to bone, and thus dislocation of articular cartilage and stripping periosteum may not be very difficult.
For a speedy work, we suggest use of a dual purpose tool composed of a small knife and a stainless steel spatula with flat edge (for cartilage dislocation) attached to the end of the handle of knife. The size of knife, spatula and handle may vary depending on user’s preference.
After deboning, the yield of boneless product was found to be higher with the present method compared to the common method, which resulted in more muscle fragmentation than did the present method. The final product contained inner space formed by bone removal. However, when a cooked product was examined on its transverse section, no appreciable empty space was seen (Fig. 2), indicating that the inner space present, as shown by inserting a filler (Fig. 2) was closed up owing to the heat denaturation of muscle protein during cooking.
The boneless chicken wing products obtained in this study appeared to us to be convenient value-added products that would appeal to many consumers. In addition to ease of consumption, boneless wing products have several advantages over bone-in wing products. They look meatier than bone-in products (Fig. 2), as expected, and require less space for freezing, storage and transportation than bone-in products. Because of larger surface areas resulting from bone removal in the boneless than in the bone-in product, marination may take less time with the boneless product. The inner space seen in the boneless product can be stuffed with food (Fig. 2) to improve the appearance of wing products. The boneless products, which can be sliced or ground, are probably preferred by people (especially the aged) who have limited number of teeth. It was concluded that the method described in the present study is useful for the production of high quality boneless wing products.
