Lentil proteins are complex macromolecules composed of amino acids linked by peptide bonds. They are a significant source of plant-based protein, particularly rich in essential amino acids such as lysine, leucine, and isoleucine. Lentil proteins are primarily globulins and albumins, which contribute to their nutritional and functional properties. These proteins play a crucial role in human nutrition, especially in vegetarian and vegan diets, due to their high protein content and digestibility. Lentil proteins are moderately soluble in water, which facilitates their use in various food applications, including soups, stews, and plant-based protein products. Their solubility in alcohol is limited, and they are generally insoluble in fats, which affects their behavior in different food matrices. Lentil proteins are not volatile, making them stable under typical cooking and processing conditions.
