Analisis proximal y contenido de hierro y calcio de Nostoc sphaericum “cushuro” deshidratado procedente de la laguna de Conococha, Catac – Huaraz

Abstract

The present research work is of simple descriptive non-experimental design and was carried out with the purpose of determining the proximal analysis of proteins, iron and calcium in dry samples of Nostoc sphaericum “cushuro” from the Laguna de Conococha, District of Catac, Province of Huaraz, Department of Ancash. The analysis of results was performed in the Excel 2016 program, through descriptive statistical parameters as average and standard deviation. For the determination of proximal analysis in 100g of pulverized Nostoc sphaericum “cushuro”, the Kjeldahl method was used, finding 26.68 ± 0.01% protein, 0.21 ± 0.03% fat, 5.77 ± 0.11% crude fiber, 11.23 ± 0.42% moisture, 7.77 ± 0.01% ash. For the determination of iron, the colorimetric method based on reactions with orthoferantothroline was used, finding 15.72 ± 2.07 mg/100g of dry sample, and for calcium the complexometric method was applied by titration with ethylenediamine tetraacetic acid (EDTA), obtaining 1224.4 mg of Ca/100g of dehydrated “cushuro” as a result. It is concluded that dehydrated Nostoc sphaericum “cushuro” is important in the diet because of its high protein, iron and calcium content and indispensable for its use in the treatment of anemia, malnutrition and osteoporosis.
