摘要: 为探究淡腌青鱼品质特征及其安全性,对各加工环节的水分含量、水分活度、pH、菌落总数、挥发性盐基氮和硫代巴比妥酸的变化,以及成品营养成分、矿物元素和组胺等进行研究。结果表明:青鱼腌制过程中,pH值逐渐上升,在清洗结束至成品阶段呈下降趋势,而水分活度、水分含量、菌落总数、挥发性盐基氮和硫代巴比妥酸总体呈下降趋势。淡腌青鱼成品中水分、粗蛋白质、粗脂肪和灰分分别为(71.23±1.16)%、(18.01±0.34)%、(8.07±0.08)%和(2.69±0.06)%;必需氨基酸和鲜味氨基酸含量分别为(5.74±0.34)%、(6.90±0.23)%,占氨基酸总量的36.17%和40.83%,符合FAO/WHO规定的人体必需氨基酸均衡模式。淡腌青鱼不饱和脂肪酸与饱和脂肪酸比值为3.43,7种不饱和脂肪酸总量为(77.4±2.23)%。淡腌青鱼微生物、组胺、重金属、挥发性盐基氮和硫代巴比妥酸等均符合相关标准。

Abstract: In order to investigate the quality and safety of lightly salted Mylopharyngodon piceus, changes in moisture content, water activity(Aw), pH, total viable counts (TVC), total volatile basic nitrogen (TVB-N) and thiobarbituric acid (TBA) during processing stages were studied, in addition to determination of muscle composition, mineral content and histamine etc. The results showed that pH increased initially in curing phase and then decreased from washing stage to drying stage, while moisture content, Aw, TVC, TVB-N and TBA kept decreasing during the whole processing stages. The moisture content, crude protein, crude fat and ash were (71.23 ± 1.16)%, (18.01 ± 0.34)%, (8.07 ± 0.08)% and (2.69 ± 0.06)%, respectively. The contents of essential amino acids (EAA) and delicious amino acids (DAA) were (5.74 ± 0.34)% and (6.90 ± 0.23)%, accounted for 36.17% and 40.83% of the total amino acids, respectively, meeting requirement of the balance style of essential amino acids ruled by FAO/WHO. However, unsaturated fatty acids/saturated fatty acid 3.43 and the total content of unsaturated fatty acids (77.4 ± 2.23)% suggested a high content of fat. Contents of microorganisms, histamine, heavy mental, TVB-N and TBA of lightly salted Mylopharyngodon piceus were acceptable in comparison to national standards.

Key words: lightly salted Mylopharyngodon piceus, processing stage, quality character, safety evaluation
