Durian (Durio zibethinus Murr.) is a seasonal fruit with a short harvesting period, requiring postharvest processing such as cutting, peeling, freeze-drying, cooking, and frying to enhance its shelf life and nutritional quality. In this study, fresh Monthong durian (MTD), MTD Sticks, MTD Cake, and MTD Chips were analyzed for polyphenols, phenolic acids, tannins, flavonoids and thermal stability.

These compounds undergo various decomposition processes under the influence of external factors, especially during transportation and storage. In this paper, it was possible to monitor changes in the terpene profile of kaffir lime juice under different storage conditions, namely, 4 °C, 20 °C, and 35 °C.

A procedure using solid-phase microextraction with gas chromatography (SPME-GC-TOFMS) was optimized and validated for the determination of terpenes of kaffir lime. Main physicochemical parameters: pH, vitamin C, citric acid and °Brix were evaluated.

The first mention of such an analytical approach likely appeared after the year 2000 and despite many advantages, it has not been applied very often. Therefore, the aim of this article is to elaborate on the concept of their combined use and to provide a curse tutorial for those considering taking such an approach.
