“…This high flavonoid and phenolic contents of WPI‐based oleoresin microspheres could be due to its greatly ramified structure, which results in controlled release of bioactive compounds 32 . Earlier, Simon‐Brown et al ., 13 and Nurhadi et al 41 . reported total phenolic and flavonoid contents of 2.20 mg GAE g −1 and 0.83 mg QE g −1 , respectively, for ginger extract powder encapsulated with different wall materials.…”

BACKGROUND Ginger oleoresin is prone to destruction from air, light and high temperatures and has a limited shelf life if kept improperly. Its viscous and sticky characteristics also make it difficult to handle and utilize. These issues can be solved via microencapsulation. The goal of this research was to evaluate how different wall materials affect the properties of microencapsulated ginger oleoresin powder. RESULTS Ginger oleoresin microcapsules were developed through spray drying technique using gum acacia (GA) and whey protein isolate (WPI) as wall materials. The characteristics of the obtained powder, including water activity, wettability and encapsulation efficiency, were evaluated, corresponded to values of 0.20, 90.54 s and 84.15% for whey protein isolate‐based ginger oleoresin powder. Whey protein isolate microcapsules also exhibited higher phenolic content (27.26 mg gallic acid equivalents g−1), total flavonoid (2.94 mg quercetin equivalents g−1) and 2,2‐diphenyl‐1‐picrylhydrazyl radical scavenging activity (68.71%) than GA microcapsules. Both WPI‐ and GA‐based oleoresin microcapsules displayed poor flowability, but possessed a metastable amorphous state as indicated by X‐ray diffraction. GA‐encapsulated oleoresin microcapsules showed a significant increase in particle size (1983 nm) compared to WPI oleoresin microcapsules. Fourier transform infrared analysis of the developed oleoresin microcapsules indicated no change in molecular structure except for a variation in peak intensity. CONCLUSION Whey protein isolate proved to be more efficient in maintaining the physicochemical and antioxidant activity of spray‐dried ginger oleoresin powder. The present study revealed whey protein‐based oleoresin powder could be used as a therapeutic agent in various nutraceutical applications. © 2022 Society of Chemical Industry.

“…However, these compounds, such as betanin [ 11 , 12 , 15 , 17 , 32 ], kaempferol [ 33 ], and protecatechuic acid [ 34 ], have been shown to stimulate biofunctional effects on living cells [ 14 ]. In addition, rutin, quercetin, kaempferol, and protecatechuic acid are known as compounds with a phenolic group in their structure, and therefore they may act as antioxidants, since they donate electrons and undergo electron delocalization [ 35 ]. In other words, the higher the number of bioactive compounds with phenolic structures in WECF, the higher the biological activity.…”

The protective effects of water extracts of djulis (Chenopodium formosanum) (WECF) and their bioactive compounds on particulate matter (PM)-induced oxidative injury in A549 cells via the nuclear factor-erythroid 2-related factor 2 (Nrf2) signaling were investigated. WECF at 50–300 µg/mL protected A549 cells from PM-induced cytotoxicity. The cytoprotection of WECF was associated with decreases in reactive oxygen species (ROS) generation, thiobarbituric acid reactive substances (TBARS) formation, and increases in superoxide dismutase (SOD) activity and glutathione (GSH) contents. WECF increased Nrf2 and heme oxygenase-1 (HO-1) expression in A549 cells exposed to PM. SP600125 (a JNK inhibitor) and U0126 (an ERK inhibitor) attenuated the WECF-induced Nrf2 and HO-1 expression. According to the HPLC-MS/MS analysis, rutin (2219.7 µg/g) and quercetin derivatives (2648.2 µg/g) were the most abundant bioactive compounds present in WECF. Rutin and quercetin ameliorated PM-induced oxidative stress in the cells. Collectively, the bioactive compounds present in WECF can protect A549 cells from PM-induced oxidative injury by upregulating Nrf2 and HO-1 via activation of the ERK and JUN signaling pathways.

“…Oil retention in the samples composed of gum arabic/cellulose was 12.23% higher than in the samples containing only gum arabic. In another study, Nurhadi et al 36 revealed the ability of spray drying encapsulation to protect bioactive compounds of red ginger extract powder during storage. These authors studied the characteristics of red ginger essential oil microcapsules obtained using varying gum arabic ratios in the growth inhibition of E. coli and S. aureus .…”
