Aqueous extractions were performed controlling the pH with CaCO3 and Ca(OH)2, using as clarifiers activated coal and activated clays in cold and warm solutions to obtain best results with cold bentonite, warm activated clay and warm activated coal. Analytical results were compared with a commercial sample of stevia.

Seeds of chirimoya and guanabana from the communities of Cumbe and Callahuanca - Yauyos, Lima were analyzed. The extraction of natural toxic was realized using ethanol as the optimal solvent, after several solvent tests, phytochemicals analysis identified :saponins, coumarins, tannins, quinones and essential oils, mostly castor oil which was confirmed by FTIR spectra. Qualitative analysis results identified: PO4(3-), AsO4(3-) and others. Toxicological tests extracts applied on larvae and fruit flies finding levels of mortality as 88% to 94% on chirimoyas and guanabanas respectively.

We worked with the cladode, gel and pulp of the fruit: red, purple and white of Opuntia ficus-indica “tuna” in the region of Ayacucho Wari Department, Huamanga province in order to determine the presence of minerals, metabolites secondary antioxidant capacity and consider a functional food. The phytochemical screening according to the method of Cain - Bohmann determined catechic the presence of tannins, steroidal saponins, flavonoids, coumarins, and alkaloids. The total fiber content was found in the range of 0,42 to 0,68%, fat 0,01 to 0,02% protein and 0,39 to 0,57%. For analysis of nutrients as found AOAC magnesium, calcium, zinc and phosphorus, potassium and iron traces. Due to the presence of these nutrients to the tuna it can be considered as a functional food. Jams pulp obtained tunas studied were evaluated according to standard NTS MINSA No. 071 / DIGESA V.01, giving as a pass...

Se trabajó con el cladodio, gel y pulpa de los frutos: rojo, morado y blanca de Opuntia ficus-indica “tuna” de la región Wari del Departamento de Ayacucho, provincia de Huamanga con la finalidad de determinar la presencia de los minerales, metabolitos secundarios, capacidad antioxidante y considerarlo un alimento funcional. El screening fitoquímico según el método de Cain – Bohmann determinó la presencia de taninos catéquicos, saponinas esteroidales, flavonoides, cumarinas, y alcaloides. El contenido de fibra total se encontró en el rango de 0,42 – 0,68%, grasa de 0,01 – 0,02% y proteína de 0,39 – 0,57%. Para el análisis de nutrientes según los métodos AOAC se encontró magnesio, calcio, fósforo y zinc, trazas de hierro y potasio. Debido a la presencia de todos estos nutrientes a la tuna se le puede considerar como un alimento funcional. Las mermeladas obtenidas ...
