White lupin (Lupinus albus L.) is a nutrient-rich legume well-adapted to Mediterranean climates and tolerant of abiotic stress. Therefore, lupins represent a sustainable crop option with high potential for use in areas where climate change impacts are intensifying. This study analysed eight cultivars, four winter and four spring ecotypes, to assess differences in nutritional and bioactive compounds. Key compounds studied included proteins, fats, carbohydrates, tocopherols, and phenolics. Spring ecotypes like 'Sulimo' and 'Energy' showed higher protein and tocopherol content, which may be ideal for protein-rich, antioxidant-rich diets. Winter ecotypes such as 'Angus' had more carbohydrates, especially fructose and raffinose, which could benefit energy and gut health. Both ecotypes showed high fibre levels, supporting digestive health. The findings suggest that ecotype influences chemical composition significantly, and each offers distinct benefits for targeted nutritional and functional food applications.
