Researchers found that choosing the right mix of probiotic bacteria dramatically improves the flavor of plant-based yogurts made from lupin and oats. A combination featuring Bifidobacterium produced the most complex, pleasant aroma—54 distinct flavor compounds—by converting off-flavors into fruity esters and acids.
The Bifidobacterium-dominant starter (Y3) produced 54 volatile flavor compounds compared to just 23 in the unfermented control, the highest of all three tested combinations.
Y3 effectively masked off-flavors like hexanal and heptanal (grassy, rancid notes common in legumes) by converting them into pleasant butyl esters and acids via a metabolic pathway called the 'bifid shunt.'
Microbial communities remained stable and formulation-specific throughout 28 days of refrigerated storage, meaning the flavor benefits persisted on the shelf.
