Biological Activities of Beng-tigré (Vigna radiata): Nutritional Aspects and Therapeutic Functions

Beng-tigre is a variety of Vigna radiata, a legume of the Fabaceae’s family newly introduced in Burkina Faso for its resilience to the effects of climate change, its high nutritional value and its potential to reduce the prevalence of chronic diseases in the population. The objective of this study was to raise awareness of the nutritional and therapeutic qualities of Beng-tigre seeds among the Burkinabe population. A legume that matures between 55 and 70 days, Beng-tigre has a high nutritional value influenced by processing methods such as germination, fermentation and cooking time. Well consumed in Asia for its high protein (23.50g), fibre (16.80g), and carbohydrate (62.75g) content, as well as its high vitamin and mineral content, Beng-tigre is used as a supplement in the preparation of weaning foods and contributes to the fight against malnutrition in infants and young children. Rich in polyphenols, polysaccharides and peptides, Beng-tigre is a functional food that can contribute to the prevention and management of certain degenerative diseases. Several in vitro studies and studies on laboratory animals have shown the anti-cancer, anti-diabetic and anti-hypertensive effect of Beng-tigre. It also acts as a prebiotic to maintain the homeostasis and functions of the intestinal microbiota. A functional food with multiple virtues, Beng-tigre can be of great use in preventive medicine in developing countries where chronic non-communicable diseases are rampant. Further studies are needed at the local level to better understand the synergistic effects of the multiple components of Beng-tigre and to ensure therapeutic convenience for the population.
