Oil-in-water (O/W) emulsions stabilized by cellulose nanocrystals (CNC) and/or sunflower proteins (SFP) were produced, aiming to study the effects of each and the mixture of these stabilizers on the interfacial behavior and physicochemical properties of O/W emulsions. The presence of CNC (non-surface activity compound) did not affect SFP solutions' adsorption kinetics since there were no differences in the interfacial tension curves of SFP and mixtures of stabilizers over time. However, either stabilizer provided alone high resistance against droplet coalescence over time (no evidence of oiling-off and no difference in the mean droplet size values), even systems with less viscoelastic interface (2 % CNC).

Article Synopsis
- The article develops and validates a multivariate model to quantify Robusta-Arabica coffee blends using near infrared spectroscopy (NIRS) and total reflection X-ray fluorescence (TXRF).
- It involves formulating 80 coffee blends and analyzing them, resulting in a significant reduction of predictive variables and improved prediction accuracy for coffee composition.
- Key elements and NIR regions were identified that correlate with the coffee varieties, utilizing data fusion to enhance understanding of the differences between Robusta and Arabica coffees.
This paper describes a robust multivariate model for quantifying and characterizing blends of Robusta and Arabica coffees. At different degrees of roasting, 120 ground coffee blends (0.0-33.
