摘要:

运用顶空固相微萃取与气质联用技术,分析3 种不同工艺生产的盐水鸭肉的挥发性风味物质,进而研究不同工艺对盐水鸭风味的影响。结果显示:共鉴定出93 种化合物,这些化合物包括烃类(24 种)、酮类(13 种)、醇类(15 种)、醛类(24 种)、酸类(5 种)、酯类(1 种)、呋喃类(3 种)、含硫化合物(3 种)、含氮化合物(3 种)、杂环化合物(2 种)。烘烤能增加鸭肉中的烃类、醇类、酸类、醛类、酯类、呋喃类以及含硫化合物的含量,对产品的风味有重要贡献。复卤后冷藏能增加鸭肉中的烃类物质、醛类物质、酸类物质、含硫化合物和杂环化合物的含量,且有利于提高产品的色泽。

关键词: 盐水鸭, 挥发性风味物质, 烘烤, 冷藏

Abstract:

The conventional processing procedure of water boiled salted dusk was modified by supplementing either cooling at 4 ℃ for 12 h or roasting 45 ℃ for 30 min following brine salting. Headspace solid phase microextraction combined with gas chromatography–mass spectrometry was used to analyze the volatile flavor composition of water boiled salted dusk products obtained using three different processing procedures. Results showed that a total of 93 compounds were identified in all three products, including hydrocarbons (24), ketones (13), alcohols (15), aldehydes (24), acids (5), esters (1), furans (3), sulfurcontaining compounds (3), nitrogen-containing compounds (3) and heterocyclic compounds (2). Roasting resulted in a significant increase in the respective relative contents of hydrocarbons, alcohols, acids, aldehydes, esters, furans and sulfur-containing compounds of water boiled salted dusk and made a great contribution to product flavor. Cooling resulted in a significant increase in the respective relative contents of hydrocarbons, aldehydes, acids, sulfur-containing compounds and heterocyclic compounds and helped enhance product color.

Key words: water boiled salted duck, volatile flavor compounds, roasting, cooling
