Contenido de fósforo en especies que conforman la bebida tradicional "Horchata Lojana" mediante Espectrofotometría UV-Visible

Abstract

Abstract: The purpose of the present investigation is to determine the concentration of phosphorus in species that make up the "Horchata Lojana", which is a traditional drink in the southern part of this country, the inhabitants ingest it daily as usual, by customs or by their medicinal benefits. The phosphorus concentration of 25 plant species of this beverage was determined, as well as of 2 commercial horchata infusions, Caserita and Surenita, and a market "tongo" (fresh herbs). In order to quantify this mineral, the UV-Visible spectrophotometry method was used, these tests were carried out in the laboratories of the Universidad Técnica Particular de Loja. The 5 species with the highest phosphorus content were: Linaza 818 ± 66, Violeta 587 + 18.29, Toronjil 537 ± 8, Borraja 494± 33, Hierba buena 484 ± 44 (mg/100 mL). The Caserita and Sureñita infusions without preparing P values: 391 ± 18 and 364 ± 17 mg/100mL. The prepared infusions (Caserita, Sureñita and fresh) acquired a P value: 5 ± 0, 5 ± 0 and 0 ± 0 mg/100 mL.
