Bagazo de caña de azúcar (Saccharum officinarum) y almidón de yuca (Mianihot esculenta) como sustituto de poliestireno en la elaboración de platos biodegradables

The objective of this research was to evaluate different percentages of sugarcane bagasse and cassava starch as a substitute for polystyrene in the production of biodegradable dishes. The factors under study were the percentage of sugarcane bagasse and the percentage of cassava starch, both with levels of 15%, 25%, 35%. A Completely Random Design was applied in a two-factor arrangement 32. Nine treatments with three replicates each were studied. 74 g of base mixture made up of cane bagasse, cassava starch, dolomite lime (calcium carbonate and magnesium carbonate), and other ingredients of the biodegradable dish such as corn starch, resin and water were used as experimental unit. The variables evaluated through statistical analysis were: mechanical properties such as the plate degradation time, deflection value, hardness value and fracturability value; Likewise, color was evaluated as part of the sensory characteristics of the biopolymer. None of the mechanical properties showed significant differences (> 0.05), however, the percentage of degradation showed T5 as the best treatment (25% sugarcane bagasse and 25% cassava starch), which did not have any level of toxicity. Within the sensory analysis, the color did not differ between treatments, so it was possible to make a biopolymer from sugarcane fiber and cassava starch on a laboratory scale.
