Tag: Goat milk protein

According to the National Institutes of Health, β-lactoglobulin accounts for nearly 10% of the total protein in ruminant milk. Contrary to a common misconception, goat milk does contain β-lactoglobulin, a whey protein that is a major allergen for some individuals, though its concentration is typically lower than in cow milk. This fundamental difference in protein composition helps explain why some people with cow milk sensitivity tolerate goat milk more easily.

According to extensive research, goat milk contains a different beta-casein protein structure than most cow milk. So, does goat's milk have A1 casein? The answer is that goat milk is naturally A2 protein-dominant, containing little to no A1 beta-casein, which makes it a gentler option for some people with dairy sensitivities.
