A comparative study on the allergenic potential of β-lactoglobulin conjugated to glucose, caffeic acid and caffeoyl glucopyranose

, but also improved the level of short-chain fatty acids (SCFAs). Caffeoyl glucopyranose with a large molecular weight and long carbon chains exerted a great influence on the allergy-related gut flora and SCFAs. Therefore, the changes in the Th1/Th2 balance and SCFA level produced by the allergy-related gut flora were responsible for reducing the potential allergy of BLG.
