TI  - Hydrolysis of peanut (Arachis hypogea L) protein concentrate by fungal crude 
      protease extract: effect on structural, functional and in-vitro protein 
      digestibility.

AB  - Peanut protein concentrates (PPCs) were subjected to hydrolysis by crude protease 
      extract (CPE) obtained from three fungi viz; Rhizopus oligosporus, Trichoderma 
      reesei, and Aspergillus oryzae and the effect on structural, functional and 
      in-vitro protein digestibility (IVPD) properties were studied. Particle size was 
      found significantly (p </= 0.05) lower in hydrolyzed samples than un-treated 
      samples. Fourier transform infrared spectroscopy (FTIR) spectrum of hydrolyzed 
      samples displayed intense absorbance peaks in the wavelength ranging from 1500 to 
      2600 cm(-1). Peanut protein concentrates hydrolyzed by CPE from R. oligosporus 
      showed higher surface hydrophobicity (564.18). Total sulfhydryl content was found 
      lower in all the hydrolyzed samples whereas, reverse trend was observed for 
      exposed sulfhydryl content. The structural changes simultaneously affected the 
      functional and IVPD attributes of hydrolyzed PPCs. In comparison to the PPCs 
      hydrolysed using crude extracts from T. reesei and R. oligosporus, PPCs 
      hydrolysed by A, oryzae showed higher solubility, water and oil binding capacity, 
      foaming capacity and foam stability. Higher IVPD values of 86.70% was also found 
      in PPCs hydrolyzed with CPE of A. oryzae. The study established that CPE 
      hydrolysis of PPCs has potential for scale-up studies and may serve as a cost 
      effective alternative to protein hydrolysis with pure enzymes.
