Finger millet: Eleusine coracana

Area of Science:

• Agricultural Science
• Food Science
• Biochemistry

Background:

• Finger millet (Eleusine coracana) is a drought-resistant cereal crop cultivated across Africa and Asia.
• The grain is notable for its high calcium and polyphenol content.
• It contains a double-headed trypsin, α-amylase inhibitor with significant biochemical properties.

Purpose of the Study:

• To explore the nutritional profile and beneficial properties of finger millet.
• To investigate its traditional and novel applications in food and beverage production.
• To highlight its potential role in health, particularly for diabetic individuals.

Main Methods:

• Isolation and characterization of the α-amylase inhibitor.
• Analysis of nutritional composition, including calcium and polyphenols.
• Evaluation of malting process for beverage and food production.
• Exploration of processing techniques like decortication, puffing, and extrusion.

Main Results:

• Finger millet exhibits resistance to environmental stressors and pests.
• Germination during malting yields α-amylase and β-amylase.
• Malted finger millet is a source of low-viscosity weaning foods with high energy density.
• Evidence suggests a low glycemic index, beneficial for diabetic patients.

Conclusions:

• Finger millet is a versatile and resilient crop with significant nutritional and health advantages.
• Its traditional uses in fermented beverages and weaning foods are supported by its properties.
• Novel processing methods expand its utility in modern food applications.
• Finger millet shows promise as a functional food ingredient, especially for managing blood sugar levels.
