NMR spectroscopy for structural elucidation of insoluble crystalline mannan from residual seeds of the edible açaí (Euterpe oleracea Mart.) pulp production

Results shown

The açaí seed mannan structure was elucidated as a main chain β(1→4) linked Manp, with ramifications of α-1,6-D-Galp in a molar ratio of 50:1 man:gal, characterizing it as a linear mannan;

The first in situ analysis of the açai seed confirmed the presence of a linear mannan structure in the endosperm cell wall;

The results highlight the need for strategies to reduce the crystallinity of the mannan, and/or the screening of mannanases that are more suitable for the hydrolysis of this crystalline mannan.
