This study aimed to determine storage conditions for microparticles containing habanero pepper extracts with maltodextrin (MD) and a 95:5 w/w mixture with precipitated silica (MDSP) as wall materials. State diagrams (SD) using water adsorption isotherms and glass transition temperatures were created. Monolayer values were 6.17 g (MD) and 6.76 g (MDSP) of water/100 g d.s. Critical water activity values (a_wC) were 0.49 for MD and 0.41 for MDSP. When stored at a_w > a_wC, both samples underwent physical transformations, with significant color changes (ΔE > 8). Conversely, storage below a_wC resulted in minimal changes (ΔE < 4), consistent with the SD.
