Abstract
El cultivo de azafrán poco a poco se ha ido introduciendo en el país dado que existen zonas edafoclimáticas óptimas para su producción, estableciéndose de norte a sur en Chile con el fin de generar el “Oro Rojo”. El Crocus sativus L. es un cultivo que ha irrumpido en los últimos años, genera una considerable cantidad de residuos orgánicos, de los cuales es un desafío comprender sus posibles usos, pudiéndose estimar cuantitativamente según datos obtenidos de información externa y local. De acuerdo con investigaciones, los desechos agrícolas del azafrán (tépalos, hojas y estambres principalmente) tendrían una variada cantidad de metabolitos secundarios como fenoles, flavonoides, ácidos orgánicos, minerales, aminoácidos y otros, con potenciales usos antimicrobianos teniendo importantes efectos en cepas bacterianas que inciden en la contaminación alimentaria. Además, presenta actividad antioxidante, por lo que su uso compromete darle valor a este subproducto. En la presente investigación se mide la composición nutricional de una muestra de residuos obtenidos en Chile y su comparación con otras y se evalúa su uso como forraje y/o como aditivo. Bajo esta información se esperan efectos positivos en el animal, beneficiando la fisiología y desarrollo de los animales evaluados al mejorar ciertas características productivas.
The cultivation of saffron has gradually been introduced in the country since there are optimal soil and climatic zones for its production, establishing itself from north to south in Chile in order to generate the "Red Gold". Crocus sativus L. is a crop that has burst onto the scene in recent years, it generates a considerable amount of organic waste, of which it is a challenge to understand its possible uses, being able to estimate quantitatively according to data obtained from external and local information. According to research, the agricultural waste of saffron (mainly tepals, leaves and stamens) would have a varied amount of secondary metabolites such as phenols, flavonoids, organic acids, minerals, amino acids and others, with potential antimicrobial uses having important effects on bacterial strains that affect food contamination. In addition, it has antioxidant activity, so its use compromises to give value to this by-product. In this research, the nutritional composition of a sample of residues obtained in Chile and its comparison with others is measured, and its use as forage and/or as an additive is evaluated. Under this information, positive effects on the animal are expected, benefiting the physiology and development of the animals evaluated by improving certain productive characteristics.
