#' @description
#' The yacon (Smallanthus sonchifolius) is a plant native to the Andes,
#' considered a traditional crop in Peru and natural source of FOS, which is a
#' type of carbohydrate that can not be digested by the and the human body that
#' have joined several beneficial properties in health, such as improve the
#' absorption of calcium, reducing the level of triglycerides and cholesterol
#' and stimulate better gastrointestinal function.
#' 
#' Proportion or fraction of the plant that is used (seeds, fruit, root) on dry
#' basis. Part usable in a proportion of total mass dissected. Plant of frijol,
#' weight = 100g and frijol = 50g then, IH = 50/100 = 0.5 or 50 percentaje.
#' Degrees Brix is a measurement of the mass ratio of dissolved sugar to water
#' in a liquid.
