2.1. Materials and samples preparationLive Japanese sea bass used in this study were purchased froman aquatic market in Jinzhou, China. The mean weight and length offish were 640 20 g and 28.5 0.43 cm, respectively. Fish weretransported to the Aquatic Products Processing Laboratory of BohaiUniversity within 0.5 h and kept alive before being processed. Thesea bass were decapitated and filleted by hand, and two fillets wereobtained from each fish. A cryogenic temperature of 55 C hasbeen suggested as ideal storage conditions for frozen meat toprevent quality changes (Zhou, Xu, & Liu, 2010). So we packed filletsin polyethylene bags and randomly separated fillets into threegroups. Three different freezing treatments were used: (T1) frozenat 18 C and kept for up to 3 months; (T2) frozen at 55 C by anultra-low temperature freezer (MDF-382E, Sanyo Co., Ltd., Dalian,China) for 24 h and then moved to a refrigerator at 18 C (as atypical frozen storage temperature) and kept for up to 3 months;(T3) frozen at 55 C and kept for up to 3 months. After that, the seabass fillets were stored in refrigerated chambers at 0 1 C during20 days for subsequent quality analysis. Fresh sea bass fillets wereobtained and then stored at 0 1 C as control. For each group, 18sea bass fillets were used, and subsequently every 4 days, microbialcharacteristics, biogenic amines and quality changes from eachมีวิเคราะห์กลุ่ม
