Safety evaluation of amino peptidase enzyme preparation derived from Aspergillus niger

Comparison of physicochemical properties of beef potentiators prepared by synergistic fermentation and traditional method

“…It is reported that A. oryzae has the largest expansion of hydrolytic genes (Vishwanatha et al ., ). Among the proteases secreted by A. oryzae , neutral proteases, the endoproteases involved in elevating utilisation efficiency of proteins during fermentation, are the dominant proteases, whereas acid proteases, the exoproteases involved in FAAs released from proteins and peptides during fermentation, are inadequate (Coenen & Aughton, ; Svendsen & Degan, ; Kitano et al ., ). However , in A. niger , acid proteases were verified as the predominating extracellular proteases, and its maximal proteolytic activity reached 1928 U g −1 during solid fermentation (Gao et al ., ).…”
