中文摘要: 采用仿天然风干和烘烤干燥加工腌腊草鱼,比较不同干燥工艺对腌腊鱼产品特性的影响。结果显示,与仿天然风干燥比较,烘烤干燥产品酸价(acid value,AV)更低,pH 值、过氧化值(peroxide value,POV)及硫代巴比妥酸值(thiobarbituric acid value,TBA)显著更高,挥发性盐基氮值(total volatile base nitrogen,TVB-N)无显著差异,风干产品呈现更低的脂肪氧化程度。风味特性方面,两种干燥工艺游离氨基酸含量差异不大,但烘烤干燥更利于促进蛋白质分解成游离氨基酸,产品在总游离氨基酸(total free amino acid,TAA)、必需氨基酸(essential amino acid,EAA)和鲜味氨基酸(delicious amino acids,DAA)上略高于冷风干燥组。挥发性风味成分分析结果,仿天然风干条件下的腌腊鱼的挥发性风味物质种类和总相对含量均高于热风烘烤干燥产品,尤其是对产品风味贡献较大的醛类、酯类化合物的种类及含量较高,自然风干更有利于腌腊鱼特征风味物质的形成。在产品色泽及质构特性方面,仿天然风干产品色泽更红润,且硬度较小,弹性值较高,呈现更佳的感官特性。

Abstract:The effects of different drying processes on the characteristics of cured fish products were compared by using natural air drying and baking and drying of cured caragana.The results showed that the acid value(AV)of the baked product was lower than that of the natural air drying,and the pH value,peroxide value(POV)and thiobarbituric acid value (TBA)were significantly higher.There was no significant difference in nitrogen values (TVB-N),and air-dried products exhibite a lower degree of fat oxidation.In terms of flavor characteristics,the free amino acid content between the two drying processes had no significant difference,but baking and drying was more conducive to the decomposition of proteins into free amino acids.The products were on total free amino acids(TAA),essential amino acids(EAA)and delicious amino acids(DAA).The baking and dryjing was slightly higher than the cold air drying group.The results of volatile flavor component analysis showed that the volatile flavor substances and total relative content of salted fish under natural air-dried conditions were higher than that of hot air baking and drying products,especially aldehydes and ester compounds which contributed a lot to the flavor of the product.The type and content were high,and natural air drying was more conducive to the formation of characteristic flavor substances of salted fish.In terms of product color and texture characteristics,the imitation natural air-dried products had a more rosy color,a lower hardness,a higher elasticity value,and better sensory characteristics.
