Abstract:
Quinoa (Chenopodium quinoa Willd.) is an Andean grain that has gained great commercial importance in the last 15 years. One of the drawbacks is the presence of an anti-nutritional factor known as saponin. The objective of this research work was to evaluate the inhibitory effect of coatings made from quinoa saponin applied on Penicillium digitatum of isolated strain and coded strain. In vivo tests of the coatings were carried out at four concentrations 15000, 11300, 7500 and 3700 ppm; The quality parameters were evaluated: damage index, firmness and presence of fungi. The loss of firmness was 6.6% in the coated samples at a concentration of 15,000 ppm and the control samples presented 5.96% loss of firmness and the damage index from the isolated strain was 11.49 and from the coded strain was 10.02. On the other hand, the presence of fungi in the samples with coating at a concentration of 15,000 ppm was at 13 days, while the standard sample had the presence of fungi at seven days, thus showing a difference of five days of delay. It is concluded that the coatings developed in this research are a good alternative for the control of green rot since it delays its appearance.
