Abstract:

The production of rapeseed peptides based on solid-state fermentation by Actinomucor elegans was investigated by one-factor-at-a-time method with respect to the effects of some technological conditions on rapeseed peptide yield, nitrogen solubility index and amino nitrogen. The optimal technological conditions were determined as follows: rapeseed meal granular diameter, 0.18 to 0.28 mm, solid-to-liquid ratio 1:1, glucose amount 3%, KH2PO4 amount 0.5%, pH 9.0, fermentation temperature 30 ℃ and fermentation time 96 h.

Key words: Actinomucor elegans, solid-state fermentation, rapeseed peptide, technological conditions, peptide yield, nitrogen solubility index, amino nitrogen
