Profiling and Characterization of Seed Storage Proteins From Borage (Borago officinalis L.) Pressed Cake as a Novel Plant‐Based Protein Source

Sustainable Food Proteins, Volume 4, Issue 1, March 2026.
Borage (Borago officinalis L.) pressed cake, a by‐product of oil extraction, was profiled and characterized to evaluate its potential as a sustainable, plant‐based protein source. Protein fractionation revealed glutelin‐like proteins as predominant, accompanied by 2S albumin, 7S, and 11S globulin‐type proteins. Proteins exhibited high thermal stability
