Lentil protein fragments make fat-free yogurt feel creamy again

The lentils in your pantry or garden bed could become the key ingredient that makes skim-milk yogurt actually satisfying, cutting the need for added fat or gums in your food.
Researchers took protein from lentils and used an enzyme to snip it into smaller pieces, creating tiny molecules that act like fat even though they contain none. When they added just a tiny pinch of this lentil powder to non-fat milk, the resulting yogurt became thick and creamy, matching the texture of whole-milk yogurt. It's a plant-based trick for making low-fat foods feel indulgent without adding actual fat.
Key Findings
Partially hydrolyzed lentil protein (LPP5-10, under 50 kDa) reached a surface hydrophobicity of 207 A.U., comparable to lecithin's 199 A.U.
Oil-holding capacity jumped to 752% compared to just 174% for native, unmodified lentil protein isolate
Adding only 0.05% LPP5-10 to non-fat milk improved gelation, storage modulus, and yield stress to match whole-milk yogurt texture

Scientists used enzymes to break down lentil protein into tiny fat-like molecules that make non-fat yogurt taste and feel as creamy as the full-fat version, offering a plant-based alternative to animal fat and synthetic texturizers.

The lentil is an annual legume grown for its lens-shaped edible seeds or pulses, also called lentils. It is about 40 cm (16 in) tall, and the seeds grow in pods, usually with two seeds in each.
