摘要
利用真空冷却、混合冷却(自然冷却+真空冷却)、自然冷却和鼓风冷却4种冷却方式将熟制腊肉的中心温度从60℃冷却至25℃,研究腊肉在4℃下贮藏期间的品质变化。并对冷却样品的冷却速率、质量损失率、质构、色泽、气味、感官得分进行分析及对比。结果显示,理化指标方面,相对其他冷却方式,真空冷却和混合冷却能够减少微生物污染,从而延长货架期;混合冷却不仅能够缩短冷却时间,提高产品口感,还能够达到延长货架期的目的。
The central temperature of cooked cured bacon was cooled from 60 ℃ to 25 ℃ by different cooling methods, namely vacuum cooling, natural + vacuum cooling, natural cooling and air-blast cooling before being stored at 4 ℃. Quality changes during storage were investigated. Four cooling methods were compared for their effects on cooling rate, mass loss percentage, texture, color, odor and sensory evaluation. The results showed that vacuum cooling and natural + vacuum cooling reduced microbial contamination thereby prolonging the shelf-life of cooked cured bacon. Moreover, the cooling time was shortened by natural + vacuum cooling method while improving the taste.
