This work aims the development of an analytical alternative to determine phenolic compounds in fruits exploiting a greener microwave-assisted extraction and photometric detection by smartphone-based colorimetry. Acerola cherry (Malpighia emarginata) was selected as model optimized Doehlert design, taking into account temperature, solvent composition, time. The Folin–Ciocalteau method used total content extracts, with 5-fold reduction reagent amount waste generation. optimal achieved 17% v/v...
Cinnamon (Cinnamomum zeylanicum) is a spice largely consumed worldwide, but there still restricted information about its fingerprint. This work aimed to investigate the mineral composition as possible marker for classification of cinnamon samples. To this aim, (P, S, Mg, Ca, K, Cu, Zn, B, Fe, Al, Mn, and Si contents) 56 ground samples from different regions State São Paulo, Brazil was determined by inductively coupled plasma optical emission spectroscopy (ICP OES). Principal component...
