Chestnuts are known for their unique flavor and nutritional value. However, the flavor changes in chestnuts after

processing remain unclear. Multi-intelligent sensory technologies and headspace solid-phase microextractionarrow

gas chromatography-mass spectrometry (HS-SPME-Arrow-GC-MS) combined with multivariate statistical

analysis were applied to evaluate the effect of packaging and heat sterilization procedures on the sensory quality

of chestnuts. The results showed that the significant variations (p < 0.05) between the different chestnut processing

methods were revealed via the electronic eye (E-eye), electronic nose (E-nose), and electronic tongue (Etongue).

The packaging had a more significant influence on the sensory quality of the chestnuts than heat

sterilization procedures. HS-SPME-Arrow-GC-MS identified 83 volatile compounds. The processed chestnuts

exhibited higher aldehyde, ester, and alkene concentrations, while N2 packaging was more favorable to flavor

elicitation and retention. Therefore, combining intelligent sensory techniques with GC-MS can rapidly determine

the chestnut quality and guide industrial production.

“北京工商大学”基于多尺度分子感官科学，系统分析了不同加工方法（如蒸煮、烘烤、油炸、冻干等）对板栗感官品质（风味、质地、色泽）的影响。通过结合化学分析（GC-MS、LC-MS、电子鼻/舌）与感官评价，揭示了关键风味化合物（如吡嗪类、醛类）及质构特性的变化规律。

感官分析检测仪器：电子舌，日本INSENT；电子鼻，德国AIRSENSE。

主要发现风味差异：

烘烤/油炸：高温引发美拉德反应，生成吡嗪类（坚果香）、呋喃类（焦甜香），但过度加热易产生苦味物质。

蒸煮：保留更多原香，但风味强度较低；关键挥发性成分（如己醛）损失显著。

冻干：最大程度保留原有风味，但缺乏高温加工特有的焦香。
