冷凍秋刀魚 (Cololabis saira) 經過泡水解凍、前處理、蒸熟放冷後,分成含皮含血合肉和去皮去血合肉二種型態魚肉,再利用絞碎機分別以2 mm、3 mm及5 mm三種孔徑的網刀絞碎;上述6種碎肉,混入加鹽擂潰魚漿及蔬菜拌勻後,成型成8 cm × 4 cm × 1 cm的重組魚排,先行凍結再經裹漿裹屑後儲存於-20℃。含皮含血合肉和去皮去血合肉兩種型態的魚肉,前者的水分低而粗脂肪高;所製成的重組魚排油炸後的硬度則是前者低於後者 (p < 0.05)。在加工過程中pH值並無顯著變化,蒸煮後魚肉的揮發性鹽基態氮 (VBN) 和硫巴比妥酸價 (TBA) 均明顯增加,而油炸後魚排的VBN和TBA均顯著下降。不同孔徑的網刀絞碎處理,對於碎肉的化學性質和重組魚排的物性並無明顯影響,但是碎肉的好氣性生菌數增加。經由官能品評結果,六種重組魚排的質地、風味及接受性均在喜歡以上的程度。

摘要abstract(英)


Frozen Pacific saury (Cololabis saira) was thawed and steam cooked. After the treated fish was cooled, it was processed into two types of flesh. One was the flesh with skin and dark muscle (WSDM), and the other was the flesh without skin and dark muscle (WOSDM). The two types of flesh were then ground into 2 mm, 3 mm and 5 mm die separately. Six-type (two-type flesh × three-type ground die) minces were mixing with salted and blended surimi and with vegetable; and then restructured into a form of 8 cm × 4 cm × 1 cm steak. After frozen, the restructured steak were battered and breaded, and then stored at -20℃. The moisture of flesh WSDM was lower than that of flesh WOSDM, but the crude fat of flesh WSDM was higher than that of flesh WOSDM. After frying, the toughness of restructured Pacific saury steak WSDM was lower than that of steak WOSDM (p < 0.05). During processing, the pH does not change significantly. The VBN and TBA of flesh WSDM and WOSDM were increased after steam cooked. However, the VBN and TBA of fried restructured Pacific saury steak with WSDM or WOSDM were decreased. The chemical properties of minces and texture properties of restructured Pacific saury steak were not changed with ground 2 mm, 3 mm, or 5 mm die. However, the aerobic bacteria of minces have been increased. The results of sensory evaluation showed that texture, flavor and acceptability of six-type restructured Pacific saury steak were above the like degree.
