Abstract:
An in-depth study of commercial carbohydrases was performed to select those that are most performing to in-
crease the protein content of two valuable agri-food waste, rice bran (RB) and soybean meal (SM). In particular,
defatted RB (DRB) and SM were subjected to hydrolysis mediated by both one and the combination of two
commercially available enzyme formulations, i.e. Ceremix® Plus MG, Celluclast® 1.5L, Ultraflo® L and Visco-
zyme® L. Sugar extraction yields, a useful parameter to evaluate the carbohydrase efficiency, were calculated as
weight of the dried supernatants obtained after each enzymatic treatment, with respect to the starting weight.
Instead, the percentage of proteins of the solid residues (DRBP and SMP) was evaluated according to the AOAC
Dumas method, using elemental analysis. In case of RB, starting from a 19% protein content, a protein enrich-
ment of 105 ± 4% was achieved using Ceremix® Plus MG and Celluclast® 1.5L. Regarding SM, an enrichment of
33 ± 4% was reached with Viscozyme® L. In both cases, the highest sugar extraction yields, specifically 64 ± 1%
and 49 ± 2%, were obtained for DRB and SM, respectively. Results showed that the selection of specific car-
bohydrases tuned according to the polysaccharides composition is essential to increase the availability of pro-
teins present in agri-food waste.
