Structural elucidation of a crystalline mannan from açaí (Euterpe oleracea Mart.) seeds
C CP/MAS solid-state NMR was employed to enable a comprehensive structural assessment. Solid-state NMR revealed the presence of a mannan I polymorph, with its crystalline nature further confirmed by X-ray diffraction. The identification of a highly crystalline linear mannan in açaí seeds provides structural insight relevant to the development of strategies aimed at reducing mannan crystallinity and designing specialized enzymatic cocktails for its efficient hydrolysis, thereby supporting the sustainable valorization of this abundant agro-industrial byproduct.
