将电子鼻测定结果与感官分析相结合,分析金华火腿3种传统烹调方式:蒸1h(B1)、2h(B2)和3h(B3);煮1h(C1)、2h(C2)和3h(C3)及煮1h(S1)、2h(S2)和3h(S3)火腿汤的风味轮廓和风味物质的变化,研究烹调前、后火腿风味的变化情况。电子鼻测定结果表明:不同的加工方式、加工时间对金华火腿的挥发性风味有显著影响,蒸1h、煮1h的火腿和煮2h的火腿汤的风味特征与原火腿接近,而蒸2h和3h,煮2h的火腿和煮1h,3h的火腿汤的风味与原火腿风味差异较大,由感官评价也得出相似的结果。金华火腿烹调前腌制味、油脂香、肉香、清香、酸味更浓,烹调后油脂香、肉香、焦味、烤肉香的评分升高。蒸后火腿的主要气味是肉香、烤肉香和油脂香,煮后火腿的主要气味是肉香、油脂香和腌肉味,煮后火腿汤的主要气味是肉香和焦味。
