Patent ID: 7270985

Claim:
A process for preparing aldehyde having molecular weight in the range of 3000-5000 D from a proteinous material for industrial applications, said process comprising the steps of; i) subjecting the proteinous material to hydrolysis to obtain protein hydrolysate and sterilizing the protein hydrolysate to obtain sterilized protein hydrolysate, ii) treating the sterilized protein hydrolysate, as formed in step (i), with 0.25-0.5% w/w of alkali metal hydride for a time period in the range of 20-30 minutes at a pH of 6-7 and adjusting the pH of the same in the range of 3-5 to obtain an alcohol containing slurry, iii) reacting the alcohol containing slurry of step (ii), with 0.01-0.5% w/w, of an organo-oxidising agent at a temperature in the range of 20-35° C. followed by adjusting the pH of the resulting solution in the range of 5-7 to obtain an aldehyde containing solution, iv) separating the aldehyde containing solution, as formed in step (iii), to obtain aldehyde.
