Summary: The maturation degree of pink pepper fruits and their powder production by cast-tape drying were studied. The process variables of circulating water temperature and thickness of paste spreading layer were analyzed for their influence on the physicochemical properties of the produced powders. Six ripening stages were observed for pink pepper fruits. A short drying time (60 min) with the lowest spreading thickness (2 mm) and the highest temperature (95 degrees C) achieved a suitable moisture content of the powders. The powders obtained had a low water activity and moisture content in all drying conditions. The color variation was minimal at a temperature of 65°C and a thickness of 3 mm. Higher levels of phenolic compounds were obtained at a slightly lower temperature and a thicker pink pepper paste layer (4 mm).

Summary: Capsiate and phenolics in different forms of BRS Moema peppers were analyzed and quantified using UHPLC-ESI-MS/MS. The peppers were found to contain significant amounts of capsiate and phenolic compounds, with esterified phenolics being the main fraction. The phenolic fractions demonstrated high antioxidant capacity, but the correlation between phenolic compounds and antioxidant activity suggested the presence of other bioactive or phenolic compounds contributing to the overall phenolic content.

Summary: In this study, four polythiourethane films with different types of polyols and isocyanates were synthesized, characterized, and foamed. The results showed that the type of isocyanate greatly influenced the crystallinity and stiffness of the polymers, while the type of polyol modified the FT-IR spectra and the decomposition curve of the material with temperature. Furthermore, the choice of isocyanate also affected the properties of the foams obtained from the polymeric material.

Summary: This study experimentally assessed the hydrodynamic characteristics of supercritical-pressure R134a in a horizontal circular tube. It was found that the hydrodynamic characteristic curve of R134a under supercritical pressure does not have a negative-slope region but a transition region. The transition region becomes more evident with increasing heat flux, while it weakens with increasing pressure and inlet temperature. Moreover, the onset of the transition region shifts in the direction of high mass flow rate with increasing heat flux.

Summary: This research aimed to valorize brewery spent grain (BSG) using subcritical water hydrolysis (SWH) modified by six different natural deep eutectic solvents (DES) and determining their bipotentialities. The findings showed that BSG hydrolysates obtained through DES-induced SWH contained high levels of sugars, proteins, flavonoids, phenolic compounds, and essential amino acids. The hydrolysates also demonstrated antimicrobial activities, and the presence of bioactive compounds was confirmed through FT-IR analysis. This comprehensive profiling of bioactive compounds from BSG using DES-mediated SWH can contribute to the efficient valorization of BSG for industrial purposes.
