【摘要】 煮制葵花籽是市场上最受欢迎的瓜子，但是煮制瓜子丧失了传统炒制瓜子特有的焦香味(焙烤焦香风味)。改进煮制葵花籽的生产工艺以增强其焦香味，可吸引更多的消费者，增加企业经济效益。为此，论文研究了焦香味煮制葵花籽的生产工艺、探寻美拉德与焦糖化反应增香的证据、并对焦香味进行GC／MS分析，得出如下结果：利用美拉德反应和焦糖化反应原理，优化葵花籽中的糖添加量，烘烤时间，烘烤温度，摊放厚度等因素，增强煮制葵花籽的焦香味。试验得到的最佳工艺结果为加糖量1％，摊放厚度是2.5cm，烘烤时间是2h，烘烤温度是160℃。改进工艺后的煮制葵花籽的焦香味显著增加，其中蔗糖的含量的变化程度与炒制葵花籽接近，揭示其美拉德反应及焦糖化的程度接近炒制葵花籽。葵花籽煮制时添加蔗糖量，来提高煮制葵花籽中的焦香味是现实可行的工艺。采用SDE提取，GC／MS分析，检测出焦香味煮制葵花籽中的18种挥发性香气物质，焦香味物质含量占总挥发性成分的52％；与普通煮制葵花籽相比焦香味成分含量显著增加。更多还原

【Abstract】 Boiled sunflower seed have the call in market, but boiling make it lose scorched flavor (baking flavor) comparing with traditional fry one. Improving processing technology of boiled sunflower seed to increase scorched flavor, it can attract more customers and increase economic benefit of enterprises. Therefore, this paper studied on scorched flavor boiled sunflower seed Processing Technology, tried to find out evidence of increase flavor by maillard reaction and caramelization, and analysed scorched flavor content by GC/MS. The results obtained were as follows:Used maillard reaction and caramelization to optimize sunflower seed sugar addition, baking time, baking temperature, spreading thickness, increase scorched flavor of boiled sunflower seed. Based on experiments, the best technology result was as follow: sugar 1%, spreading thickness 2.5mm, baking time 2h and baking temperature 160℃.Scorched flavor of Boiled sunflower seed after improvement increases significantly. The sugar content variation degree of boiled sunflower seed were similar with fried one and proved that the maillard reaction and caramelization degree were similar with fried one. It is a feasible technology to increase scorched flavor of sunflower seed by Controlling sugar addition during boiling.Detected out 18 kinds of volatile aroma components by using SDE and GC/MS. The scorched flavor material content account for 52% of total volatile components. The scorched flavor material content were increased significantly comparing with normal boiled sunflower seed.更多还原
