“…While convention has led to the use of high levels of O 2 in packs to promote oxymyoglobin development, more recently, attempts have been made to investigate the use of lower O 2 levels in MA packs of red meat so as to counteract some of the negative aspects of packing meat using high O 2 contents (higher oxidation levels, increased toughness, increased drip loss etc.) while at the same time providing a product which is still visually acceptable to the consumer (O'Sullivan, Cruz-Romero, & Kerry, 2011;Zakrys, Hogan, O'Sullivan, Allen, & Kerry, 2008, Zakrys, O'Sullivan, Allen, & Kerry, 2009Zakrys-Walliwander, O'Sullivan, O'Neill, Allen, & Kerry, 2011b;Zakrys-Walliwander, O'Sullivan, Walshe, Allen, & Kerry, 2011a). While the effects of high O 2 levels in MA packs are known to have an impact on flavour, and one which is negative when perceived by panellists with the capacity to detect rancid notes in red meat products, little is known about the impact that resting meat prior to cooking following its removal from MA packs has on flavour acceptability among consumers.…”
