The objective of the current study was to analyse the effects of double transport and season on sensorial aspects of lamb's meat quality in dry climates. A total of 144 lambs were sampled in a 3 × 2 × 2 factorial design, testing three types of double transport along the residence time at a pre-slaughter classification centre or CC (0, 7 and 28 days) and two seasons (summer and winter), with two replicates in each season. Meat from the M. longissimus was analysed in terms of pH and WHC and tasted by a trained sensory panel in terms of lamb odour intensity, tenderness, juiciness, lamb flavour intensity, fat flavour intensity, liver flavour intensity, metallic flavour intensity and overall liking. Meat sensorial quality traits were not significantly affected by double transport. Season had a significant (P<0.001) effect on all variables analysed, except for lamb flavour intensity and overall liking. Interactions between the fixed effects were not significant, with the exception of tenderness. Season significantly affects several sensorial variables, and they seem to be independent of double transport, with the exception of tenderness.
本研究的目的是分析在干旱气候下双重运输和季节对羊肉品质感官特性的影响。采用3×2×2析因设计对144只羔羊进行采样,测试在屠宰前分级中心或CC停留时间(0、7和28天)的三种双重运输类型以及两个季节(夏季和冬季),每个季节设置两个重复。对背最长肌的肉进行pH值和保水性分析,并由经过训练的感官评价小组对羊肉气味强度、嫩度、多汁性、羊肉风味强度、脂肪风味强度、肝脏风味强度、金属风味强度和总体喜好度进行品尝。双重运输对肉的感官品质特性没有显著影响。除羊肉风味强度和总体喜好度外,季节对所有分析变量均有显著(P<0.001)影响。固定效应之间的交互作用不显著,但嫩度除外。季节显著影响几个感官变量,除嫩度外,它们似乎与双重运输无关。
