Evaluación del suplemento alimenticio de harina de papa china (Colocasia esculenta l.) enriquecido con concentrado proteico de soya (Glycine max)

Abstract

This research aimed at evaluating the dietary supplement of Chinese potato flour (Colocasia esculenta l.) enriched with soybean (Glycine max). To achieve this, bromatological, microbiological, sensory, and cost-benefit analyses were carried out. Three different levels (2%, 4%, and 6%) were applied including a control treatment without Chinese potato flour, with four replicates distributed in a completely randomized design. For statistical analysis, the analysis of variance (ANOVA) was conducted; Tukey’s test (p<0.05) was used for bromatological analyses, and for sensory analysis, the Kruskal Wallis test was employed, working based on medians. The results of the microbiological analysis showed that all treatments meet the INEN 2383, 2016 standards. Additionally, the 6% treatment showed the best bromatological characteristics, with 4.60% protein, 2.97% fiber, and 4.62% ash content. The 6% treatments had the highest score and acceptability, whereas the 2% treatment showed a favorable profitability with a gain of 0.70 cents for every dollar invested. In conclusion, the addition of soy concentrate enhances the nutritional characteristics of the dietary supplement, and therefore, it is recommended to be applied in moderate levels in food.
