Temperature, memory effect, and cross-contamination are suspected to contribute drift in electronic tongue (e-tongue) sensors, therefore corrections required. This paper aimed assess the disturbing effects on sensor signals during measurement with an Alpha Astree e-tongue develop correction techniques. Apple juice samples were measured at different temperatures. pH change of apple was cross-contamination. Different sequential orders model solutions applied evaluate effect. Model...
Nitrogen-rich adulterants in protein powders present sensitivity challenges to conventional combustion methods of determination which can be overcome by near Infrared spectroscopy (NIRS). NIRS is a rapid analytical method with high and non-invasive advantages. This study developed robust models using benchtop handheld spectrometers predict low concentrations urea, glycine, taurine, melamine whey powder (WPP). Effectiveness scanning samples through optical glass polyethylene bags was also...
Tomato, and its concentrate are important food ingredients with outstanding gastronomic industrial importance due to their unique organoleptic, dietary, compositional properties. Various forms of adulteration often suspected in the different tomato-based products causing major economic sometimes even health problems for farmers, industry consumers. Near infrared (NIR) spectroscopy electronic tongue (e-tongue) have been lauded as advanced, high sensitivity techniques quality control. The aim...
Plums are one of the commercially important stone fruits that available on market in both fresh and processed form most sought-after products prunes, cans, jams, juices. Maturity, harvest, post-harvest technologies fundamentally determine relatively short shelf life plums which is often threatened by Monilinia spp. Causing brown rot worldwide. The aim present research was to use advanced analytical techniques, such as hand-held near infrared spectroscopy (NIRS) electronic tongue (e-tongue)...
In this study we aimed to investigate the effect of heat treatment on spectral pattern honey using near infrared spectroscopy (NIRS). For research, sunflower, bastard indigo, and acacia honeys were collected from entrusted beekeepers. The not subject any before. Samples treated at 40 °C, 60 80 100 °C for 60, 120, 180, 240 min. This resulted in 17 levels, including untreated control samples. 5-hydroxymethylfurfural (HMF) content was determined Winkler method. NIRS spectra recorded a handheld...
Coffee is both a vastly consumed beverage and chemically complex matrix. For long time, an arduous chemical analysis was necessary to resolve coffee authentication issues. Despite their demonstrated efficacy, such techniques tend rely on reference methods or resort elaborate extraction steps. Near infrared spectroscopy (NIRS) the aquaphotomics approach, other hand, reportedly offer rapid, reliable, holistic compositional overview of varying analytes but with little focus low concentration...
Gaining prominence as indispensable culinary ingredients, tomato powders aren't exempt from fraudulent practices. While the complexity of conventional authentication methods hinders their adoption routine assessment tools, our study examines efficiency aquaphotomics a potential alternative, that entails limited preparation steps and involves no solvent extractions. Tested across three varieties, aqueous blends comprising concentrations in range [0%–20%] two adulterant types (bulking agent,...
With its adverse effects on the health of consumers and global economy, food adulteration is considered to be one pressing issues our times. Beef Protein powders (BPP) are particularly among most fraud-prone products mainly due their ever-growing consumption. For purpose study, FT-NIR spectroscopy was applied quantify four commonly used adulterants: Melamine (M), Urea (U), Glycine (G) Taurine (T) in BPP. Analysis with chemometric tools proved efficiency aforementioned technique as a rapid...
