Pearl Millet Processing and its Effect on antinational Factors: Review paper
Pawase PA, UD Chavan, SB Lande
Pearl millet is underutilized food grains in many countries despite which is rich source of micronutrient like iron, calcium zinc etc. However the processing rate of pearl millet is very low as compare to other cereals. Major issue of processing of pearl millet is its antinutritional factors and coloring property. India is one of the leading producers of pearl millet followed by African countries. Most important key point of pearl millet is drought resistant which can be tolerate over scarcity of water. Hence the regions of water scarcity will produce easily huge amount of pearl millet however poor processing rate due to many more reasons. Purpose: Pearl millet (Pennisetum glaucum) is a rich source of nutrients as compared to the major cultivated cereal crops. However, major factors which limit its utilization are the presence of anti-nutritional factors (phytate, tannins and polyphenols) which lower availability of minerals and poor keeping quality because of higher lipase activity. Therefore, this paper aims to focus on the impact of different processing methods on the nutrient composition antinutrtional-nutritional components of pearl millet. Design/methodology/approach: This is a literature review study from 1983 to 2017, focusing studies related to pearl millet processing and their effectiveness in the enrichment of nutritional value through reduction of anti-nutritional compounds. Findings: From the literature reviewed, pearl millet processing through various methods including milling, malting, fermentation, blanching and acid as well as heat treatments were found to be effective in achieving the higher mineral digestibility, retardation of off ﬂavor, bitterness as well as rancidity problems found during storage of ﬂour. Originality/value: Through this review paper, possible processing methods and their impact on the nutrient and antinutrient proﬁle of pearl millet are discussed after detailed studied of literature from journal articles and thesis.
