A novel alternative for the detection of milk adulteration by dilution based on determination protein content is proposed. The proposed method involves precipitation proteins salting-out effect copper sulfate and proportional adsorption Cu(II) precipitate. Subsequently, photometric measurements remaining amount smartphone-based digital colorimetry are conducted to determine content. procedure rapid (sample throughput 32 assays/h), precise (coefficient variation = 3.0%, n 20), environmentally...
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...
Brazil is the largest producer of sugarcane and its derivatives in world, one consumers derivatives. Sugar places a position great prominence Brazilian feed, either by direct consumption or as component industrialized products, from increasing country. samples taken local market were analyzed quality table sugar consumed state Sao Paulo (Brazil). The analysis parameters basic attributes characterization was according to methodology developed ICUMSA (2005; 2011) modified Copersucar (2002)....
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...
