The expansion properties and physical-chemical characteristics of dry squid that rehydrated with oyster shell ash solutions were investigated. Samples that treated with deionize water and commercial alkali solution were negative and positive control. Samples rehydrated with soakage processing (SA) and ultrasound processing (UT) were compared. The result showed expansion rates and rehydration indexes of ashed oyster shell solutions were 114.47-119.94% and 1.18-1.26 g/g (H2O/dry mass) during for SA samples. Moreover expansion rates and rehydration indexes for UT samples were 116.70- 120.33% and 1.20 -1.27 g/g (H2O/dry mass). The value of TVBN and TMAN were 18.47-20.12 mg/100g and 1.84-1.91 mg/100g for samples with SA processing. Besides, TVBN and TMAN content of samples treated with UT were 9.27- 11.12 mg/100g and 1.82-1.85 mg/100g. Dry squid rehydrated with oyster shell ash solutions could improve expansion properties, moreover decreased TVBN and TMAN content within samples. Ultrasound processing could increase moisture transfer ratio and decrease processing time.
