Headspace–gas chromatography–ion mobility spectrometry (HS-GC-IMS) was used to detect the volatile flavour compounds of white radishes under six different planting conditions. A total of 26 volatile flavour compounds were identified qualitatively and the common characteristic flavour compounds of organic and conventional white radishes were determined, as well as the differences in the composition and content of volatile flavour compounds in different white radishes. The flavour fingerprint of white radish was established, and principal component analysis (PCA) clearly showed that the samples in a relatively separate space could be well-distinguished.

We established the aroma quantitative system of Hehong tea by using QDA. We found that sweety was probably the symbolic aroma sub-attribute of Hehong tea, and woody was the characteristic sub-attribute of LC, and there was a certain correlation among the aroma sub-attributes. A total of 21 volatile components importantly contributed to the aroma sub-attributes of Hehong tea. Furthermore, we screened out 18 marker volatile compounds that may be used as important indicators for distinguishing the three types of Hehong tea.

Therefore, this study aims to evaluate the catalytic properties of six solid acids (HND-34, HND-6, HND-580, HND-2, HND-8 and HND-26) for the synthesis of benzyl cinnamate. Results show that HND-26 was the most effective solid acid to catalyse the esterification reaction of cinnamic acid with benzyl alcohol. By using response surface methodology, the influence of key experimental factors on the yield of benzyl cinnamate was investigated and the maximum yield (95.1%) was obtained under the optimized conditions (58°C, cinnamic acid/benzyl alcohol 1:20 (mol/mol), HND-26 loading 13.8% and 25 hours). The activation energy of cinnamic acid conversion with benzyl alcohol was 30.3 kJ/mol.

The results showed that the extraction time of V60 and flannel cloth filter were shorter. Kalita filter offered longer extraction time and obtained the highest amount of chlorogenic acids than other drippers. In the volatile profiles of aroma compounds, flannel cloth and stainless-steel filters obtained higher total volatile compounds that may due to less volatiles were absorbed by filter material compared with paper filters, V60 and Kalita.

Due to the lack of natural products, many essential oil compounds are imitated by others made of cheap chemicals, which studies have shown to have a great danger to human health. From this point of view, it is necessary to search for new ways to increase natural products, the most important of which are essential oils. One of these methods is the use of bioregulators to modify the production of essential oil and its components to increase its biological use area. Thus, the variations of coriander green fruits essential oil were evaluated under different rates of glutathione and α-tocopherol to determine the possibility of using them in the production of essential oil from coriander green fruits. Coriander plants were treated during cultivation at rates of glutathione (0, 0.2, 0.4 and 0.6 g L⁻¹) without or with α-tocopherol (0.4 g L⁻¹). Green fruits essential oil was separated by hydro-distillation and analysed by gas chromatography and gas chromatography/Mass spectrometry; data were statistically analysed by two ways analysis of variance. Plants treated with 0.6 g L⁻¹ glutathione with α-tocopherol gave the maximum values of green fruits yield and essential oil content (% and yield per plant). The major essential oil constituents were linalool, undecan-3-ol and yomogi alcohol; while oxygenated monoterpenes were the main fractions. Plants exposed to glutathione with α-tocopherol doses resulted in higher values of major components and main fraction than those subjected to glutathione rates.

However, some subtle high-boiler adulterants like vegetable oils and synthetic polymers go unnoticed via these analyses leading to the penetration of adulterated essential oil in the market. In the current study, the thermogravimetric analysis (TGA) and differential thermogravimetric analysis (DTGA) were utilized and suggested as a rapid, convenient and precise technique for the detection of high-boiler adulterants in essential oils using the most expensive agarwood oil as a case study. The TGA pattern of pure samples reveals single-stage volatilization (agarwood oil: 110–260°C, castor oil: 340–500°C, coconut oil: 330–450°C and polyethylene glycol-400: 260–390°C), whereas the adulterated sample exhibits two-stage volatilization in both lower- and higher-temperature zone owing to the presence of agarwood oil and high-boiler adulterant. The DTGA of pure agarwood oil shows only one point of major weight loss, whereas that of the adulterated sample shows two points of major weight loss corresponding to both oil and adulterant. Different percentages of adulterants (5%, 10%, 30% and 50%) have been quantified using TGA and DTGA with the highest accuracy.
