Nutritional and functional properties of Moringa oleifera

Area of Science:

• Agricultural Science
• Nutritional Science
• Food Science

Background:

• Moringa oleifera is a widely cultivated plant known for its nutritional value.
• Understanding regional variations in nutrient composition is crucial for optimizing its use.
• Functional properties of plant-based ingredients are key for food product development.

Purpose of the Study:

• To evaluate the proximate composition, vitamin C, mineral content, and functional properties of Moringa oleifera leaves.
• To compare these nutritional and functional attributes from two distinct ecological zones in Bangladesh.
• To assess the potential of Moringa oleifera leaves as a food ingredient.

Main Methods:

• Proximate analysis for protein, fat, fiber, and ash content.
• Quantification of Vitamin C, Calcium (Ca), Phosphorus (P), and Potassium (K).
• Determination of Water Absorption Capacity (WAC), Fat Emulsification Capacity (FC), and Fat Stabilization (FS).

Main Results:

• Moringa oleifera leaves exhibited high protein content (22.99-29.36%) and were low in fat (4.03-9.51%), fiber (6.00-9.60%), and ash (8.05-10.38%).
• Significant levels of Vitamin C (187.96-278.50 mg/100g), Ca (1.322-2.645%), P (0.152-0.304 g/100g), and K (1.317-2.025 g/100g) were found.
• Functional properties showed high Water Absorption Capacity (158.00-415.00%), Fat Emulsification Capacity (28.30-117.65 mL/l), and Fat Stabilization (333.33-1000 mL/l).

Conclusions:

• Moringa oleifera leaves are a rich source of essential phytonutrients and minerals.
• The leaves possess favorable functional properties, indicating their versatility in food applications.
• These findings support the use of Moringa oleifera leaves as a balanced ingredient for human and animal nutrition.
