This study was conducted to compare the physicochemical traits of dry-cured hams made from two different three-way crossbred pigs: Yorkshire×Landrace×Duroc (YLD) and Yorkshire×Berkshire×Duroc (YBD). Animals were slaughtered at a live weight of 110 to 120 kg and cooled at 0°C for 24 h in a chilling room, the ham portion of the carcasses were cut and processed by dry-curing for physico-chemical analyses. While the moisture and crude protein contents of dry-cured ham were higher in YLD than in YBD, crude fat and ash content were higher in YBD (p<0.05). The salt contents of ham from YBD were higher than those from YLD (p<0.05). YBD ham samples showed a higher L* and b* values than those from YLD, while YBD ham showed lower a* value (p<0.05). Thiobarbituric acid reactive substances (TBARS) and volatile basic nitrogen (VBN) values of YLD hams were lower than those of YBD samples (p<0.05). Hardness, gumminess, chewiness, and shear force values of YBD ham were higher than those of YLD sample (p<0.05). Saltiness was significantly higher in YBD ham than in YLD samples (p<0.05). YLD ham displayed a superior quality than YBD. Considering the meat quality parameters of two-way crossbred ham, YLD hams could be more suitable for the production of dry-cured products.
约克夏×长白×杜洛克(YLD)和约克夏×伯克夏×杜洛克(YBD)。猪在活重110至120千克时屠宰,并在0°C的冷藏室中冷却24小时,将胴体的火腿部分切割下来并通过干腌处理进行理化分析。虽然YLD干腌火腿的水分和粗蛋白含量高于YBD,但YBD的粗脂肪和灰分含量更高(p<0.05)。YBD火腿的盐分含量高于YLD(p<0.05)。YBD火腿样品的L值和b值高于YLD,而YBD火腿的a*值较低(p<0.05)。YLD火腿的硫代巴比妥酸反应物质(TBARS)和挥发性盐基氮(VBN)值低于YBD样品(p<0.05)。YBD火腿的硬度、胶黏性、咀嚼性和剪切力值高于YLD样品(p<0.05)。YBD火腿的咸味明显高于YLD样品(p<0.05)。YLD火腿的品质优于YBD。考虑到二元杂交火腿的肉质参数,YLD火腿可能更适合用于生产干腌产品。
