Abstract
A process is disclosed to treat the protein hydrolysate, prepared conventionally from a proteinous source, with alkyl halide to obtain alcohol which is subsequently oxidized to obtain aldehyde under certain specified conditions, thereby converting large protein molecules into aldehyde based industrial products of much smaller molecular size.

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 sodium borohydride 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;
- and
- iv) separating the aldehyde containing solution, as formed in step (iii), to obtain aldehyde.
A process for preparing an aldehyde having a molecular weight of about 3000-5000 Daltons from a proteinous material, said process comprising the steps of:
- i) subjecting the proteinous material to hydrolysis to obtain protein hydrolysate;
- ii) treating the protein hydrolysate formed in step (i), with sodium borohydride at a pH of about 6-7 and adjusting the pH to about 3-5 to obtain an alcohol-containing slurry;
- iii) reacting the alcohol-containing slurry of step (ii), with an organo-oxidizing agent followed by adjusting the pH of the resulting solution to about 5-7 to obtain an aldehyde- containing solution.
