Plant-based milk alternatives (PBMAs) are increasingly
consumed
as a dairy alternative [OlsonS.
Olson, S.
Milk and Non-Dairy Milk
– US – 20212021].
Plant foods are rich sources of (poly)phenols, but concentrations
of these bioactive phytochemicals in processed PBMAs are not well
documented. We procured twenty-seven PBMA products of 6 types (almond,
coconut, oat, pea, rice, and soy) for (poly)phenol analysis. Samples
were analyzed via ultra high-performance liquid chromatography-diode
array with mass spectrometry. The (poly)phenol content of PBMAs varies
and is dependent on plant source, brand, and added flavorings. Soy
milk had the highest concentration and rice milk had the lowest (91.9
± 2.7 and 0.9 ± 0.2 mean mg ± SD/cup serving, respectively).
Almond milk, the most widely consumed PBMA, averaged 12.1 ± 8.2
mg/cup serving, but the majority of (poly)phenols are derived from
added flavorings. PBMAs contain a wide range of potentially bioactive
(poly)phenols and may contribute significantly to overall dietary
(poly)phenol intake with the potential to impact health outcomes.
