Studies on Algerian Pearl Millet Starch Extraction Methods

Abstract
Pearl Millet (Pennisetum glaucum (L.) R. Br) is a very important cereal mainly used in Africa and India, it has an interesting nutritional content reaching 65% starch and 16% protein (on dry basis), and can resist to the difficult arid Sahara conditions such as saline soils and unpredictable rain. This study aims to value and exploit Algerian Pearl Millet through the extraction of grains starch by both conventional wet milling method (in presence of a microbial growth inhibitor) and Ultrasound method. Extracted starches were considered in terms of yield, recovery, chemical composition, and other physical properties to estimate the efficiency of the extraction method. The ultrasound extraction method gave enhanced yields and recoveries, and higher starch purity, with ranges of (30 - 52 %), (46 - 75 %), and (91 - 94 %) respectively, all this in a short period of time without generating any alkaline waste. These results are expected to be helpful in the production of starch from Pearl Millet in Algeria, where this cereal is considered as a low cost and a high nutritious source.
