Abstract

A variety of attempts have been made to reduce the dependence on petroleum raw materials based plastics which are limited supply and difficult to degrade, so it can cause the environment problems. Polyvinyl Alcohol/PVA, one of the water-soluble polymer, has good compatibility with fillers, i.e., nanocellulose addition, so it can resulted a composite films that are environmentally friendly and the mechanical properties close to conventional plastic. The objectives of research was to know the effect of pineapple nanocellulose fibers addition on the improvement of the mechanical properties of composite films based on polyvinyl alcohol. The method for manufactured of composite films using solution casting. A simple in a one-pot process was carried out by mixing of PVA solution in various concentration of pineapple nanocellulose fibers (10% - 50%) and glycerol with 2 levels (0% and 1%). Films observations were tensile strength, elongation, crystallinity, and morphology. The results shows that the addition of nanocellulose fibers 10-40% were effective in increasing tensile strength and elongation, but the higher addition (of up to 50%) resulted in decreased elongation. The addition of glycerol on the composite film tends to lower the tensile strength and elongation. This is supported by the XRD data showed that the addition of nanocelullose was also effective to improve the crystallinity properties of the films, but the properties of crystallinity decreased after adding glycerol. The best mechanical properties of composite film produced by the treatment on nanocellulose 40% addition and without glycerol.

Abstract

The primary active components in ginger oleoresin are gingerol and shogaol, with gingerol exhibiting significant pharmacological activities such as anti-inflammatory, antioxidant, and analgesic effects. However, gingerol is heat-sensitive and degrades at elevated temperatures, limiting its functional efficacy when consumed. To overcome this limitation, encapsulation of ginger oleoresin was performed to enhance its physical and functional properties and improve its bioavailability. This study utilized the ionotropic gelation method to encapsulate ginger oleoresin, resulting in the formation of beads. Alginate was employed as the encapsulation matrix. The dried beads were characterized using FTIR, SEM, disintegration tests, and encapsulation efficiency was assessed via UV-Vis spectrophotometry. Results demonstrated that alginate beads containing ginger oleoresin could be successfully synthesized using the ionotropic gelation technique, with alginate as the polymer and CaCl2 as the cross-linking agent. Ginger oleoresin concentrations of 0.9%, 0.7%, 0.5%, and 0.3% were tested. The highest encapsulation efficiency, 72.48%, was obtained with a ginger oleoresin concentration of 0.7%. Surface morphology analysis revealed that the alginate beads exhibited a rough, porous texture with visible folds. Furthermore, the dry beads disintegrated within 30 minutes. Keywords: alginate, beads, encapsulation, ginger oleoresin, ionic gelation method
