Exploring the performance and biodegradability of Edible Biopolymer blends incorporating Pistacia atlantica subsp. Mutica Gum and Plasticized Poly(lactic acid).

Blending biopolymer is a key objective in development of innovative materials and effectively enhances the characteristics of the components to achieve tailored properties. This study introduces five eco-friendly blends in different ratios, created by melt-blending polymers, incorporating Pistacia atlantica subsp. mutica gum into plasticized poly (lactic acid) with 16% acetyl tributyl citrate.

Polylactic Acid/Saqqez Gum Blends for Chewing Gum Applications: Impact of Plasticizers on Thermo-Mechanical and Morphological Properties.

This study investigated a blend of poly (lactic acid) (PLA) and Saqqez gum, with a weight ratio of 70:30, respectively, along with two plasticizers, acetyl tributyl citrate (ATBC) and polyethylene glycol (PEG), at three different concentrations (14%, 16% and 18% by weight of the PLA). The blend was analyzed using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), tensile tests, water-absorption behavior (coefficients of water absorption, sorption, diffusion and permeability of the samples during 240 h) and chemical resistance (exposure to 1 mol/L HCl and 1 mol/L NaOH for 240 h). The desired elastomer blend was then used to prepare natural chewing gum, which was subsequently subjected to texture profile analyzer (TPA) tests and sensory evaluation.

Chewing gum base: A comprehensive review of composition, production, and assessment methods: Advances and approaches in biodegradability.

The gum base mass is a colloidal system and the main component of chewing gum; which is an inert, non-nutritious, indigestible, and insoluble part of chewing gum, therefore this substance does not dissolve in the mouth when chewed. The gum base plays the most crucial role in determining the mechanical properties, flexibility, and overall quality of chewing gum. Moreover, it acts as a delivery system to transport sweeteners, flavorings, and other ingredients in chewing gum.
