The yacon root is a member of the sunflower family. The roots of yacon has inuline. lnuline is a polyfructosane, which helps to moderate blood sugar levels (pass through the digestive tract unmetabolized). Yacon therefore has considerable value to dieters and people with diabetes. The quantitative analysis shows mineral macronutrients (Na, K, Mg, Ca, P). and micronutrients (Fe, Zn, Mn). The qualitative analysis shows very important secondary metabolites (amino acids, carbohydrate, reducing sugars, flavonoides)

Eating mushrooms are an alternative, which provide high biological and nutritional values, because of their proteins and the high level of their macro nutrients.

En el presente trabajo desarrollamos y adecuamos una tecnología de cultivo y producción de hongos comestibles.
