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
