Exploring kodo and foxtail millet as novel sources of starch and β-glucan: a short critical review
摘要
Minor millets, known for their significant starch and β-glucan content hold tremendous potential in enhancing the nutritional and functional attributes of food products. This manuscript focuses on the extraction, modifications, and physicochemical properties of starch and β-glucan in two minor millets, namely, kodo and foxtail millet to broaden their applications. Wet milling and the use of enzymes, particularly amylases, have been employed to isolate starch and β-glucan from minor millet flour. While kodo and foxtail millets contain approximately 60–70% starch, their β-glucan yield is only 1–2%, significantly lower than that of barley and oats. Both of these minor millets play a significant role in providing energy and essential minerals to populations in economically disadvantaged regions. A comprehensive understanding of the physicochemical and structural characteristics of millet starch and β-glucan is essential for optimising their utilisation. This paper delves into the influence of genetics, agricultural practices, and post-harvest processing on the content and characteristics of these components.
