摘要:

比较了冷藏解冻、静水解冻、室温解冻、超声波解冻、微波解冻5 种不同解冻方式对中国对虾物理和化学特性的影响,分析了中国对虾物理和化学特性之间的相关性。结果表明:解冻对虾肉色泽具有显著性变化,冷藏解冻后的对虾肌肉解冻损失率、蒸煮损失率、硫代巴比妥酸值还原值和羰基含量最低,Ca2+-ATP酶活性最高,为最适合中国对虾的解冻方法。中国对虾的化学性质和物理性质之间具有显著的相关性。

Abstract:

The objective of the present study was to elucidate the physico-chemical changes of Chinese shrimp treated with
five different thawing methods including cold-storage thawing, water immersion thawing, ambient temperature thawing,
ultrasonic thawing, and microwave thawing. Different thawing methods exerted significant effects on shrimp quality
and among five thawing methods, cold-storage thawing caused the least thawing loss, cooking loss, carbonyl content,
and thiobarbitric acid-reactive substances (TBARS) value and the highest Ca2+-ATPase activity. There were significant
correlations between physical properties and chemical properties for Chinese shrimp.

Key words: Chinese shrimp, thawing methods, physicochemical properties, quality
