Chachafruto starch: Physicochemical characterization, film-forming properties, and 3D printability.

This work aimed to characterize the physicochemical, film-forming properties, and 3D printability of a nonconventional starch from chachafruto. The chachafruto native starch (CHS) presented an excellent extraction yield (10 % db) and purity (99 % db), along with an oval and round morphology, a smooth surface with few defects, and a mean diameter of 15.4 μm.

Effect of Essential Oils from Lemongrass and Tahiti Lime Residues on the Physicochemical Properties of Chitosan-Based Biodegradable Films.

This work aimed to evaluate the impact of adding two essential oils (EO) from lemongrass (LEO) and Tahiti lime (TLEO) on the physical, mechanical, and thermal properties of chitosan-based biodegradable films. Six film formulations were prepared: two controls with chitosan concentrations of 1% and 1.5% /, two formulations combining the two chitosan concentrations with 1% LEO /, and two formulations combining the two chitosan concentrations with 1% TLEO /.

Influence of Ulluco Starch Modified by Annealing on the Physicochemical Properties of Biodegradable Films.

This work aimed to evaluate the use of annealing (ANN) ulluco starch in the preparation of biodegradable films and its impact on the physicochemical properties of the materials. Three film samples (FS1, FS2, and FS3) were prepared at a fixed starch concentration (2.6% /) using glycerol as a plasticizer and then compared to a control sample (FSC) prepared with native ulluco starch.

Non-conventional starch from cubio tuber (Tropaeolum tuberosum): Physicochemical, structural, morphological, thermal characterization and the evaluation of its potential as a packaging material.

This work aimed to characterize the physicochemical, structural, morphological, and thermal properties of a non-conventional starch obtained from cubio (Tropaeolum tuberosum), as well as to evaluate the potential use of this native Andean tuber in the preparation of biodegradable packaging. The cubio starch (CUS) showed an intermediated apparent amylose content (31.2 %) accompanied by a high CIE whiteness index (90.

Influence of Ulluco Starch Concentration on the Physicochemical Properties of Starch-Chitosan Biocomposite Films.

This work aimed to prepare ulluco starch (US)/chitosan (Ch) edible films and evaluate the effect of the concentration of US on their physicochemical properties. The use of edible films is a means of adding value to the ulluco crop and evaluating the viability of using new sources to produce packaging materials. Different samples were prepared at different US concentrations (2%, 3%, 4%, and 5% /) and a fixed chitosan concentration (1.

Characterization of ulluco starch and its potential for use in edible films prepared at low drying temperature.

The aim of this work was to characterize the starch obtained from ulluco (US) and evaluate its use in edible films prepared using different US concentrations (2.0, 2.5, and 3.

Effects of temperature, starch concentration, and plasticizer concentration on the physical properties of ulluco (Ullucus tuberosus Caldas)-based edible films.

Ulluco starch could be a promising renewable source for the production of biodegradable or edible films, as an alternative to plastic. This would mitigate the negative impact of plastics on the environment. The aim of this work was to study the effect of the starch concentration (SC), glycerol concentration (GC), and drying temperature (T) of ulluco starch-based films on their physical properties using stepwise regression (SR) and artificial neural network (ANN) approaches.

Characterization of chitosan edible films obtained with various polymer concentrations and drying temperatures.

Chitosan is a promising material that could be used for the development of edible coatings and films on an industrial level because of its film-forming, biodegradable, non-toxic, and antimicrobial characteristics. The aim of this work was to evaluate the effect of the polymer concentration (0.5%, 1.
