摘要: 本文研究了冻藏过程中温度波动对猪肉肌间冰晶、颜色和新鲜度的影响。结果显示:经过21d的冻藏处理,温度波动越剧烈,冰晶体积增大幅度越大。-10℃恒温冻藏样品具有最小的冰晶相当直径67.20μm,而-20℃~-10℃~-20℃处理后样品的冰晶相当直径为86.32μm。温度波动对颜色(L*、a*、b*)、TBARS没有显著影响(p>0.05)。TVB-N值随温度波动剧烈程度增大而增大。

Abstract: Effects of temperature fluctuation on ice crystal,color and quality of pork muscle during frozen storage were studied in this paper.Results showed that:quality of pork deteriorates more when larger ice crystal forms after more temperature fluctuation.Equivalent diameter is smallest in-10℃(21days)sample such as 67.20μm;and largest(86.32μm)in-20℃~-10℃~-20℃ sample.There is no significant effect on color(L*,a*,b*)and TBARS(p>0.05),but TVB-N increases with more temperature fluctuation.
