Summary: Competitive adsorption of cellulose nanofibers at oil-water interface in Pickering emulsion is studied, and the effects of different types of nanocelluloses, particle concentrations, and oil content on the stability and droplet size of emulsions are investigated. Both cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF) can stabilize emulsion droplets, with CNC producing smaller droplets and higher stability. The presence of CNF in the mixture reduces the ability of CNC particles to adsorb at the oil-water interface. The stability of emulsions is mainly influenced by oil content and total particle concentration.

Summary: A simple strategy of synthesizing polyimine-coated cellulose nanofibrils (CNF) was developed for composite reinforcement. The polyimine coating allows CNF to be easily dried while maintaining its morphology and providing mechanical reinforcement in certain polymer composites. However, the coating may not be effective in other composite systems.

Summary: In this study, cellulose nanofibrils (CNFs) were incorporated into xylan-alginate films to enhance mechanical and barrier properties for food packaging applications. The CNFs had fiber diameters between 10 and 80 nm and formed a highly entangled web-like structure. The incorporation of CNFs into the xylan-alginate matrix increased tensile strength and Young's modulus of the films, while improving water vapor permeability without significant impact on thermal properties.

Summary: This study reveals that Cecropia telenitida contains abundant ursane and oleanane pentacyclic triterpenes with similar oxygenation patterns to those found in food matrices, suggesting specific medicinal benefits related to the modulation of T2D. The biosynthetic pathway in C. telenitida demonstrates that PTs always share the same oxygenation patterns of ursane or oleanane scaffolds. Through traditional medicinal use and historical consumption of PTs in fruits, it is suggested that a group of molecules sharing a closely related scaffold can express effectiveness in medicinal benefits.

Summary: Cacao mucilage exudate (CME) can be used to produce bacterial cellulose (BC), but high sugar content, low pH, and limited nitrogen sources in CME can hinder G. xylinus growth affecting cellulose yields. By diluting CME and adding a nitrogen source, BC production significantly increased. Scaling up BC production from 30 mL to 15 L under lab-scale conditions showed no significant changes in yields and production rates, suggesting industrial possibilities are feasible.

Summary: In this study, two bis(hydrazones) compounds based on a pyridine-hydrazone-pyrimidine-hydrazone-pyridine template were synthesized and their structures were confirmed. The compounds were found to self-assemble into different complexes in the presence of Co(II) and Zn(II) metal ions, with the Co(II) complexes showing the ability to respond to electrochemical potentials. Additionally, the behavior of a grid-type Co(II) complex was studied, revealing a linear correlation between temperature and LUMO energies.

Summary: The dehydration process of cacao mucilage exudate (CME) was studied to produce cacao syrup (CS) at different temperatures (60°C and 70°C) and pH levels (4.0 and 5.0). The chemical composition of CS was not significantly affected by temperature or pH. The average concentrations of fructose, glucose, and sucrose in the syrups were 27.79%, 25.56%, and 12.46% respectively, while the organic acids-citric, malic, lactic, tartaric, and fumaric-were present in concentrations of 5.12%, 3.01%, 0.20%, 0.16%, and 0.002% respectively. The formation of 5-(hydroxymethyl)furfural (HMF) during heating treatment was below regulatory standard limits. These findings highlight the potential of CME as a sustainable and nutritious ingredient source for the food industry.
