Summary

This study investigates how controlled germination periods affect the nutritional and antinutritional profiles of two underutilised African crops — pearl millet (Pennisetum glaucum) and grain amaranth (Amaranthus cruentus) — with a view to optimising flour quality for food use. The research likely demonstrates that germination progressively reduces antinutrient concentrations while modifying proximate and mineral compositions, thereby improving the bioavailability of key nutrients. The findings contribute to evidence on low-cost, traditional food processing techniques that can enhance the nutritional value of cereal and pseudocereal flours in contexts where food insecurity and micronutrient deficiency are prevalent.

UK applicability

The study is primarily relevant to sub-Saharan African food systems where pearl millet and grain amaranth are staple crops; however, findings on germination as a processing technique to reduce antinutrients and improve mineral bioavailability have broader applicability to UK interest in alternative grains, complementary food formulation, and nutrient bioavailability research.

Key measures

Proximate composition (%); mineral concentrations (mg/100g); antinutrient levels (phytate, tannin, oxalate mg/100g); germination period (days)

Outcomes reported

The study measured changes in proximate composition (moisture, protein, fat, fibre, ash, carbohydrate), mineral content, and antinutrient levels (such as phytates, tannins, and oxalates) in pearl millet and grain amaranth flours across varying germination periods.
