This study focused on the effects of a humidity-stabilizing sheet (HSS) containing different levels of glycerol (humectant) and a drip-absorbing sheet (DAS) on quality parameters of frozen/thawed bigeye tuna meat stored in sealed containers at 4°C for 3 days. As the glycerol concentration increased, the humidity around samples and increases in volatile basic nitrogen (VBN) were suppressed, while the weight loss percentage and total ATP-related compounds (t-ARCs) were increased. Tuna portions wrapped with HSS and DAS and then unwrapped showed no difference in Hunter color values L*, a*, and b* or K values. Wrapping tuna samples with any kind of sheet seemed to effectively maintain the initial values of thiobarbituric acid reactive substances (TBARS) and metmyoglobin percentage (Met-Mb%). Based on the analysis of these parameters, we conclude that HSS is a good packaging material that can be employed in the preservation of frozen/thawed, chilled tuna meat.
