Abstract
Abstract The invention relates to the treatment of protein hydrolysates with a view to reducing their content of bitter substances. This process comprises contacting the hydrolysate with a solid ligneous adsorbent of vegetable origin, for example based on carob, and collecting the debittered hydrolysate after separation from the adsorbent.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
32 words
A process for debittering an enzymatic hydrolysate of whey protein which comprises contacting the hydrolysate with an adsorbent consisting of desugared carob particles at a temperature of from 10° to 60° C.
Claim 2
Dependent Claim
32 words
A process for debittering an enzymatic hydrolysate of whey protein which comprises contacting the hydrolysate with an adsorbent consisting of desugared carob particles at a temperature of from 10° to 60° C.
Claim 3
Dependent Claim
20 words
A process as claimed in claim 1, wherein the adsorbent is pretreated by washing with acid and/or stripping with steam.
Claim 4
Dependent Claim
20 words
A process as claimed in claim 1, wherein the particles of adsorbent have diameters of from 0.3 to 5 mm.
Claim 5
Dependent Claim
20 words
A process as claimed in claim 1, wherein the hydrolysate is contacted with the adsorbent for 5 to 60 minutes.
Claim 6
Dependent Claim
26 words
A process as claimed in claim 1, wherein the hydrolysate and the adsorbent are contacted in hydrolysate/adsorbent proportions of from 10 to 400 ml. per gram.
Claim 7
Dependent Claim
16 words
A process as claimed in claim 1, wherein the adsorbent is suspended in the protein hydrolysate.
Claim 8
Dependent Claim
19 words
