Roasted dried chili, used to improve texture and taste, is important for various cuisines. The effect of roasting at 90 °C for 25 min on the chemical profile and bioactivities of dried chili extracted by petroleum ether was investigated. Based on GC-MS analysis, the crude extracts of roasted dried chili exhibited different chemical profile compared to the control. Roasting of dried chili significantly increased total phenolic compounds. Consequently, the antioxidant activity indicated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and ferric reducing antioxidant power (FRAP) significantly improved. Conversely, a reduction in the antibacterial agents, capsaicin (32.36%) and dihydrocapsaicin (9.11%), in the roasted sample resulted to a decline in antibacterial activity. The extracts showed a strong activity against followed by and compared to based on the results of agar disk diffusion, minimal inhibitory concentration (MIC), minimal bactericidal concentration (MBC), and electron scanning microscopy observation.

Plants frequently encounter phosphate (Pi) starvation due to its scarce availability in soil, necessitating an adaptive phosphate starvation response (PSR). This study explores this adaptation in pepper (Capsicum annuum L.) under low-Pi stress, focusing on the PHOSPHATE STARVATION RESPONSE (PHR) gene family.

Studies were conducted focusing on the drying of chili pepper fruits ( L.), cultivar Cyklon, using convective (AD), convective-microwave (AMD), vacuum (VD), and freeze-drying (FD) methods. The influence of the drying method and temperature on the kinetics of the process and selected quality attributes of the dried product were evaluated.

The aim was to study the shelf-life over 18 months of storage (no light and oxygen exposure) of chili peppers flavoured olive oils comparing flavouring methods of co-milling of fresh chili peppers with sound olives at mill scale with temporary and permanent infusion of dried chili peppers in olive oil. Tocopherols, secoiridoids and capsaicinoids by HPLC-DAD, volatile compounds by HS-SPME-GC-MS, and sensory profiles were studied. The decrease in tocopherols and secoiridoids was greater in "infusion" samples, while a significant increase in capsaicinoids was observed in "permanent infusion" samples.
