摘要:

为筛选适用于大球盖菇采后品质提升的干制技术,探究了热泵干制和射频干制技术对大球盖菇风味成分含量及品质的影响。不同干制技术对大球盖菇样品风味成分含量及品质影响较大。脂质、烷烃、杂环类物质是射频干制的大球盖菇样品中的主要挥发性化合物,醛酮醇类物质是热泵干制的大球盖菇样品中的主要挥发性化合物,挥发性成分主要富集在初级醇类、酮类、杂芳香族化合物的合成代谢通路上。甜味、鲜味氨基酸是两种干制样品中的主要氨基酸种类,其中,谷氨酸、丝氨酸、丙氨酸和缬氨酸等是主要氨基酸;热泵干制样品中滋味成分核苷酸、氨基酸、有机酸总量及等鲜浓度值均高于射频干制样品。热泵干制样品鲜甜味滋味成分的电子舌及挥发性硫化物和芳香族化合物的电子鼻响应信号更高。大球盖菇干品的风味成分、感官及质构分析结果显示,热泵干制技术更有利于大球盖菇干品形成愉悦风味和较好品质外观,该技术有望进一步推广应用于大球盖菇采后品质提升。

Abstract:

In order to screen post-harvest drying techniques that is suitable for the quality enhancement of Stropharia rugosoannulata mushroom, this study investigated the effects of heat pump drying and radio frequency drying on the flavor content and quality of S. rugosoannulata mushrooms. The effects of different drying technology on the flavor content and quality of the mushroom samples were found to be significant. Lipids, alkanes, and heterocyclic substances were the main volatile compounds in the radio frequency drying samples, and aldehydes, ketones, and alcohols were the main volatile compounds in the heat pump drying samples, and the volatile components were mainly enriched in the anabolic pathways of primary alcohols, ketones, and heteroaromatic compounds. Sweet and umami amino acids were the main amino acid types in both drying samples, with glutamic acid, serine, alanine, and valine being the main amino acids. The total amount of taste components, including nucleotides, amino acids, and organic acids, and the value of equivalent umami concentration were higher in the heat pump drying samples than those in the radio frequency drying samples. The electronic tongue and electronic nose response signals of umami and sweet taste components, and volatile components such as sulfides and aromatic compounds in the heat pump drying samples were higher. The results of flavor components, sensory and textural analyses showed that the heat pump drying technology was more conducive to the formation of pleasant flavor and better-quality appearance of dried S. rugosoannulata mushrooms, and this technology is expected to be further popularized and applied to improve the post-harvest quality of S. rugosoannulata mushrooms.

Key words: Stropharia rugosoannulata, drying technology, volatile components, taste components
