Extraction and characterization of potato (solanum tuberosum) starch leona blanca variety

Abstract

The purpose of this research was the extraction and characterization of potato starch variety Leona Blanca, to evaluate the possibility of its use as an ingredient in the food industry. The variety of tuber used presented oblong shape, white pulp color, medium size and good texture. The starch extraction process was carried out by means of a wet route and by natural sedimentation, it was characterized physicochemically presenting the following values: Humidity 12.660%, Ash 0.853%, Fat 0.120%, Fiber 0.140%, Protein 0.350%, Carbohydrates 85.87%, pH 6.34, Acidity 0.0027 meq lactic acid / g starch. The results obtained show that its composition is within and not far from the comparison ranges and that this type of starch can be included in food systems as a thickening agent, dusting agent, stabilizer, gelling agent, in the preparation of edible coatings and other industrial applications.
