Review on“Development and Evaluation of Banana Flower (Musa paradisiaca) as an Iron-Rich Nutraceutical Supplement”

Iron deficiency anemia remains one of the most common nutritional disorders globally, with a higher prevalence in developing nations such as India. The adverse effects and limitations associated with synthetic iron supplements have led to increasing interest in natural, cost-effective, and plant-derived alternatives. In this regard, banana flower, which is generally discarded as a waste product during banana cultivation, has gained attention as a promising nutraceutical source due to its rich nutritional and phytochemical composition.

Various studies, including those conducted by Bhaskar et al. (2012) and Mohapatra et al. (2010), have demonstrated the significant nutritional and functional properties of banana flower. It is abundant in dietary fiber, phenolic compounds, and essential minerals such as iron, making it a suitable candidate for incorporation into functional food products. Recent investigations further validate its potential in the development of value-added formulations.

The formulation of nutraceutical granules using banana flower provides an efficient means of nutrient delivery, enhances stability, and improves ease of consumption. Therefore, its utilization not only offers health benefits—especially in combating iron deficiency—but also contributes to economic value by transforming agricultural waste into a functional product.

2.1 Nutritional Importance of Banana Flower

Banana flower (Musa spp.) is recognized as a highly nutritious plant component with significant potential in the preparation of functional foods and nutraceutical products. Scientific studies indicate that it contains a balanced composition of macronutrients, micronutrients, and bioactive compounds that contribute positively to human health.

One of the key nutritional features of banana flower is its high dietary fiber content. This fiber plays an important role in supporting digestive health, enhancing bowel regularity, and reducing the risk of chronic conditions such as cardiovascular diseases and diabetes. As reported by Bhaskar et al. (2012), the fiber content also contributes to antioxidant activity and aids in metabolic regulation.

In addition to fiber, banana flower contains moderate amounts of proteins and carbohydrates, making it a valuable supplementary ingredient in food formulations. It also provides essential vitamins such as vitamin C and vitamin E, both of which function as antioxidants. These vitamins help in protecting the body against oxidative stress and in strengthening the immune system.

Furthermore, banana flower is a good source of important minerals including iron, calcium, magnesium, and potassium. Its notable iron content makes it particularly beneficial for the prevention and management of iron deficiency anemia.

4. Products Developed from Banana Flower

Banana flower (Musa spp.) has attracted increasing attention in recent years owing to its rich nutritional profile and adaptability in the development of various food products. Several research studies have demonstrated its successful incorporation into a wide range of value-added and functional food formulations.

One of the most common processing approaches involves converting banana flower into powder form, which serves as a key ingredient in multiple nutraceutical and food applications. This powdered form is widely utilized in the formulation of nutraceutical granules, capsules, and dietary supplements, particularly for enhancing iron intake and improving overall nutritional status (Saifullah et al., 2020).

Apart from nutraceutical applications, banana flower powder has also been incorporated into bakery products such as biscuits, bread, and muffins. The inclusion of banana flower significantly improves the dietary fiber and mineral content of these products, thereby making them healthier alternatives to conventional bakery items (Singh et al., 2016).

Studies conducted by Sharmila et al. (2016) have further highlighted its potential in the preparation of functional beverages and plant extracts. Due to its antioxidant properties, banana flower contributes to additional health benefits when used in herbal drinks and health tonics.

In addition, banana flower has long been used in traditional culinary practices, particularly in Asian cuisines. It is commonly prepared as curries, pickles, and chutneys, which not only enhance dietary variety but also offer medicinal advantages.

Overall, banana flower can be effectively utilized to develop a variety of products, including:

• Nutraceutical granules and powders
• Bakery products (such as biscuits and bread)
• Functional beverages

6.1 Materials

• Banana flowers (Musa paradisiaca) were sourced from local agricultural fields.
• The collected plant material was carefully washed with clean water to remove adhered impurities.
• The outer layers (bracts) were discarded, and the inner edible portion was cut into smaller segments.
• These pieces were dried in a hot air oven maintained at 40–45°C for 5–7 days to achieve complete dehydration.
• The dried material was then reduced to a fine powder using suitable grinding equipment.
• The prepared powder was stored in tightly sealed containers to prevent moisture absorption.

6.2 Chemicals and Excipients

• A combination of ethanol and chloroform was used as the solvent system for extraction.
• Corn starch was incorporated as a disintegrant to facilitate tablet breakdown.
• Binding of granules was achieved using gum acacia or carboxymethyl cellulose (CMC).
• Stearic acid was included to act as a lubricant during formulation.
• Colloidal silicon dioxide was utilized to enhance powder flow as a glidant.
• All substances used in the study were of analytical grade to maintain experimental accuracy.

6.3 Preparation of Banana Flower Extract
