Dispersed LIF spectra recorded using large helium droplets (∼800 nm diameter): (a) bare RB, fluorescence as a function of the RB oven temperature, (b) spectra recorded for different Au oven temperatures at a constant RB doping level, (c) hexane@RB core@shell particles for different hexane doping pressures (no Au doping), (d) Au@hexane@RB particles for different hexane doping levels and constant Au and RB oven temperatures. The red “hexane+” spectrum has been recorded at a higher hexane partial pressure than the yellow “hexane” spectrum.

The percentage of remaining vitamin B₁ in selected formulations placed in 40°C oven analyzed using HPLC and is shown in . No significant change (more than 5% loss) was detected in the amount of vitamin B₆ in the formulations kept at 40°C oven. The amount of vitamin B₁ and B₆ was also constant during incubation at room temperature.

Chili sorption isotherm experimental set up: 1- Temperature and air speed controller, 2 – suction air fan, 3- chili sample for sorption analysis placed above glycerol-water mixture, 4 – heat resistant sealed glass jar to hold glycerol-water mixture to maintain constant relative humidity, 5 – oven opening gate, 6 – oven tray.
