中文摘要: 以乳鸽为原料,对干腌后的原料分别进行连续高温干制和低温+高温干制,基于水分、酸价、过氧化值、硫代巴比妥酸值、色差、感官评定和挥发性风味指标的检测,探究不同干制方式对产品的脂质氧化、品质变化和挥发性风味差异的影响。结果表明:随着干制时间的延长,乳鸽的L*、a*、b*整体均呈下降趋势,酸价、过氧化值、硫代巴比妥酸值持续上升,且干制温度越高,上升速率越快;连续高温干制的腊乳鸽的酸价、过氧化值、硫代巴比妥酸值分别为2.33 mg/g、0.16 g/100 g和2.52 mg/100 g,产品共检出20种挥发性风味物质,7种关键挥发性风味物质;而低温+高温干制的腊乳鸽酸价、过氧化值、硫代巴比妥酸值分别为2.60 mg/g、0.18 g/100 g和1.98 mg/100 g,共检出34种风味物质,14种关键挥发性风味物质;其中辛醛、肉桂醛、壬醛、香草醛、异辛醇和苯乙酮是两种腊乳鸽产品共同的关键挥发性风味物质,其对风味贡献大。两种干制方式的腊乳鸽产品感官评分无显著性差异(P>0.05),但低温+高温干制组检测出挥发性风味物质数量较多,脂质二级氧化产物较少,能更好地保留乳鸽的营养物质。
Abstract:With suckling pigeon as raw material,this paper explored the effects of different drying methods on lipid oxidation,quality changes,and volatile flavor differences of the products.Two methods of continuous high-temperature drying and low temperature+high temperature drying were used to dry the pickled pigeons.And moisture,acid value,peroxide value,thiobarbituric acid value,color,sensory evaluation,and volatile flavor were analyzed.Results showed that the L*,a*and b*of the pigeons had an overall downward trend,and the acid value,peroxide value,and thiobarbituric acid value continued rising with the extension of drying time,with higher drying temperature leading tohigher increasing rate.Under the continuous high-temperature drying,the acid value,peroxide value,and thiobarbituric acid value of cured pigeon were 2.33 mg/g,0.16 g/100 g,2.52 mg/100 g,respectively,and 20 volatile flavor substances were detected,including 7 key substances.Under low temperature+high temperature drying,the three indexes were 2.60 mg/g,0.18 g/100 g,1.98 mg/100 g,respectively,and 34 volatile flavor substances were detected,including 14 key substances.Octylaldehyde,cinnamaldehyde,nonanal,vanillin,isooctyl alcohol,and acetophenonewere the common key volatile flavor substances of the two products,which contribute a lot to the flavor.There was no significant difference in the sensory evaluation of cured pigeon products between the two drying methods(P>0.05),but the low temperature+high temperature drying group had more volatile flavor substances and fewer secondary lipid oxidation products,and better retainedthe nutrients of cured pigeons.
