To compare the eating quality (EQ) of wet (WA) and dry aged (DA) mutton longissimus thoracis et lumborum (LTL) and semimembranosus (SM), bone-in leg and loin primals from 81 merino cull ewes were WA or DA for 14, 28, 42 or 56 days. Untrained consumers (n = 540) assessed the excised LTL and SM for EQ (tenderness, juiciness, liking of flavour and overall liking, 0-100), quality grade and respective willingness to pay (WTP). LTL scored higher than SM for EQ, P < 0.001 for all consumer sores. Mean LTL EQ scores were > 70 and mean SM EQ scores >54. Ageing method had no significant effect on LTL or SM EQ (P > 0.05 for all consumer scores). Ageing beyond 14 days improved SM and LTL tenderness. Consumers most often graded LTL and SM quality grades as "better than everyday" and "good everyday" respectively; corresponding WTP was 26.90 $AUD/kg and 18.80 $AUD/kg. Extended ageing periods improved mutton tenderness.
为比较湿腌（WA）和干腌（DA）美利奴淘汰母羊的胸腰段最长肌（LTL）和半膜肌（SM）、带骨腿部和腰部切块的食用品质（EQ），选取81只美利奴淘汰母羊，将其LTL和SM分别进行14、28、42或56天的湿腌或干腌处理。未经训练的消费者（n = 540）对切下的LTL和SM的EQ（嫩度、多汁性、风味喜好和总体喜好，0 - 100）、质量等级以及各自的支付意愿（WTP）进行评估。LTL的EQ得分高于SM，所有消费者评分的P < 0.001。LTL的平均EQ得分> 70，SM的平均EQ得分> 54。陈化方法对LTL或SM的EQ没有显著影响（所有消费者评分的P > 0.05）。陈化超过14天可改善SM和LTL的嫩度。消费者最常将LTL和SM的质量等级分别评为“优于日常”和“日常良好”；相应的WTP分别为26.90澳元/千克和18.80澳元/千克。延长陈化时间可改善羊肉嫩度。
