The use of active packaging made from biodegradable polymers can contribute to the environment and to the food industry by increasing the shelf life of their products. This study aimed to produce chitosan-based films incorporated with the invertase enzyme (1, 2, 5, 9, and 10 %) as an alternative to avoid sucrose crystallization in the confectionery industry. The optimum activity of the invertase enzyme was observed at 55 °C and pH 5, thus, the films made with the film-forming solution adjusted to pH 5 and dried at 55 °C were compared with those without pH adjustment and dried at room temperature.

Multifunctional PLA films were fabricated through the solution casting method by incorporating cardanol oil (CA) and amine-functionalized graphene (AFG). The effect of the CA, and AFG on the structural, mechanical, thermal, thermo-mechanical and antioxidant properties of PLA films were investigated. FTIR analysis of PLA-CA films showed distinct peak positions at 1590 cm corresponding to the aromatic CC bonds of CA, showing that CA is compatible with the PLA.

Background Toothbrush manufacturers commonly use bristle materials such as nylon, polybutylene terephthalate, polypropylene, polyethylene terephthalate, boar hair, bamboo, carbon fiber, silicone, polylactic acid, or their modifications such as Curen. Nylon filaments have long been demonstrated to be durable and are widely used, but not much is known regarding the performance of Curen filaments compared to nylon filaments. This in vitro study compared the stiffness, abrasion potential, abrasion resistance, and bristle surface changes of Curen and nylon filaments.

Gelatin is a versatile substance extensively used in medical and pharmaceutical industries for many applications, including capsule shells, X-ray film, infusion for plasma substitute, and the fabricating of artificial tissue. Fish scale gelatin is a profitable alternative source as a halal material despite its inferior quality. An addition of phenolic cross-linker may enhance the qualities of fish scale gelatin.
