Because of consumer demand for consistency in product texture, food ma
nufacturers are demanding that variations in the texture of meat ingre
dients be minimized. While aging carcasses for 2 to 3 hr post-chill be
fore deboning reduced average fillet toughness, food manufacturers rep
ort that some fillets remained unacceptably tough for some application
s. This study examines the effects of post-chill aging time on the tou
ghness of breast fillets.
