Abstract


To determine the secondary metabolites, quality indicators and organoleptic characteristics of stems meal from Agave fourcroydes (Henequen) grown in Cuba, five henequen stems, of approximately nine years old, were collected. The meal was stored for six months. The following analyzes were performed in triplicate: phytochemical screening , pH, refractive index, density, acidity, water soluble solids, appearance, dissolution capacity, pulverization degree, color, odor, taste and homogeneous capacity. In the ether extract, coumarins predominated and in the ethanolic extract, the flavonoids and anthocyanidins. In the aqueous extract, alkaloids, saponins, flavonoids, mucilages and reducing carbohydrates had little presence. This plant material has a slightly acidic pH (5.18), 1.33 refractive index, 0.31 g/mL of apparent density, 0.76 % acidity and 1.50 ºBrix of water soluble solids. The organoleptic characteristics of stems meal from A. fourcroydes showed good physical
appearance, partial dissolution capacity, good pulverization, light beige color, pleasant odor, slightly sweet taste and good homogeneity. According to the obtained results, the stems meal from Agave fourcroydes could be used as a nutraceutical product in the farm animals diets.
