史氏鱘被消費(fèi)者廣泛接受,為了將其魚(yú)肉進(jìn)一步加工成魚(yú)糜產(chǎn)品,需要去除魚(yú)的厚皮、骨頭、粘液、臭味、肌漿蛋白和不良物質(zhì),將獲得的白色肌肉作為進(jìn)一步加工的主要成分。據(jù)報(bào)道,預(yù)加熱可以改善魚(yú)糜的凝膠性質(zhì),使得最終形成的凝膠具有更高的質(zhì)構(gòu)性能和彈性。然而,魚(yú)的種類(lèi)不同則預(yù)加熱響應(yīng)也不同,目前尚無(wú)研究表明史氏鱘魚(yú)糜的凝膠特性和預(yù)加熱響應(yīng)間的關(guān)系。近來(lái),低鹽的健康膳食理念被廣泛關(guān)注,使得降低魚(yú)糜中的鹽含量成為重要的研究課題。鈉攝入過(guò)多（>2克/天,相當(dāng)于每天5克鹽/天）不僅容易造成高血壓,而且會(huì)增加因中風(fēng)和因心血管疾病而過(guò)早死亡的風(fēng)險(xiǎn)�；谝陨犀F(xiàn)狀,本研究的目的是:（1）研究在高溫預(yù)加熱條件下史氏鱘魚(yú)糜的凝膠特性,并評(píng)估史氏鱘魚(yú)糜凝膠的常規(guī)特性和質(zhì)量,確定是否可以將其用于制備魚(yú)糜。（2）本研究旨在將鹽從常規(guī)濃度(30 g kg^-1)降到低濃度(3 g kg^-1),從而制備更健康的魚(yú)糜產(chǎn)品,同時(shí),通過(guò)添加一些潛在的、有益健康的和易獲得的添加劑（卵磷脂,L-精氨酸,L-組氨酸）來(lái)增強(qiáng)低鹽魚(yú)糜的凝膠性能。該研究得到的主要結(jié)果如下:1.結(jié)果表明,當(dāng)預(yù)加熱溫度為...
