This paper deals with the evaluation of crystalline structure and thermal properties of injection molded parts based on polylactic acid (PLA) matrix reinforced by banana and hemp natural fibres (NF). Using differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD) methods were evaluated thermal properties and crystalline structure of PLA/NF composites, depending on the amount of natural fibres within the weight ratio of 10% up to 30%. We observed that hemp and banana fibres work like natural nucleating agents and thus subsequently improve the material properties of PLA. We also observed process of melt (primary) and cold (secondary) crystallization of PLA/NF composites depending on cooling rate.

Maize Starch

In this study, the thermal properties of quinoa and maize starch were evaluated and related to their digestibility. Lower gelatinisation and retrogradation parameters were obtained in quinoa starch, suggesting a better susceptibility to the disruption of the crystalline structure. These results were accompanied with a higher percentage of hydrolysis in raw quinoa, reaching more twofold higher than in raw maize starch. Besides, the slopes calculated by a Lineweaver-Bürke transformation showed similar values in raw quinoa and maize starches. Taken together, these characteristics of quinoa starch could provide more digestible benefits than the current treatment, raw maize starch, in glycogen storage disease patients.
