“…Another study by Yuan et al (Yuan, Lin, Huang, & Li, 2017), tested different extraction methods to obtain essential oils from A. officinarum. They extracted essential oils by steam distillation (SD), ultrasonic-assisted solvent extraction (UAE), and supercritical fluid extraction (SFE).…”

“…They extracted essential oils by steam distillation (SD), ultrasonic-assisted solvent extraction (UAE), and supercritical fluid extraction (SFE). The essential oil composition showed significant differences between methods, thus authors suggested that the method of choice will depend on the aimed product (Yuan, et al, 2017). For instance, the most abundant essential oil in samples from the three extraction methods was 1,8-cineole (also known as eucalyptol).…”

“…The dried rhizomes of this plant can be used to cure stomachache, flatulence, and itching as an herbal medicine in China. According to recent research reports, galangal essential oil is chiefly composed of 1,8-cineole and other oxygencontaining monoterpenes (19,20), which has been proved to have plenty of pharmacological effects such as antimicrobial, antioxidant, and anti-inflammatory (21,22).…”

Galangal essential oil is obtained from the rhizomes of galangal with proven anti-inflammatory, antioxidant, antiviral, and antimicrobial properties, which are valuable in the food industry. To explore the effect of galangal essential oil on the quality of pineapple juice, 0.05, 0.1, 0.2, and 0.4% galangal essential emulsion were added, and their influence on the physical stability, physicochemical properties, microbial quantity, and aroma profiles of cloudy pineapple juice were evaluated. The essential oil emulsion of galangal is a milky white liquid with a strong aroma of galangal. The pH values of emulsion increased from 4.35 to 5.05 with the increase in essential oil concentration, and there was no significant difference in the particle size of the pineapple juice. The results showed that the galangal essential oil emulsion was stable and the stability of the cloudy pineapple juice was significantly enhanced by the essential oil emulsion determined using LUMiSizer. The cloudy pineapple juice with a 0.2% essential oil emulsion showed the most stability during storage. The lightness of the cloudy pineapple juice increased instantly with the essential oil emulsion addition. In addition, the microbial quantity of the cloudy pineapple juice was decreased by the individual essential oil emulsion or combined with thermal treatment to hold a longer shelf life. The microbial counts in pineapple juice treated by 0.4% essential oil emulsion and thermal treatment only increased from 1.06 to 1.59 log CFU/ml after 4 days of storage at 25°C. Additionally, the pH and total soluble solids showed a slightly increasing trend; however, the value of titratable acidity, free radical scavenging capacity, and ascorbic acid content of the cloudy pineapple juice showed no significant change. Finally, the results of the electronic nose showed that the aroma components of the pineapple juice were changed by the essential oil emulsion and thermal treatment, and the difference was especially evident in the content of the sulfur, sulfur organic, and aromatics compounds. Consequently, the results indicated that galangal essential oil emulsion can be used as juice additives to improve the quality attributes and extend the shelf-life of cloudy pineapple juice.
