Many relatively specific reagents, particularly a variety of metal complexes, have been developed as an aid to the isolation of individual amino acids. An example is provided by the isolation of L-proline from a gelatine hydrolysate using the chromium complex ammonium rhodanilate ammonium dianiline-... 

Difference between the leucine content of each sample and that of the gelatin hydrolysate. 

Referring to the gelatin hydrolysate resulting from the papain treatment in the absence of any L-leucine n-alkyl ester. 

The gelatin hydrolysates were produced in 5000 ml vessels using the following hydrolysis parameters S = 30% dry matter (corresponding to 26.6% protein (N x 5.55)) pH 5.0 - 5.1 T = 55°C mass of reaction mixture = 4000 g. The enzymes used were Alcalase, Neutrase, and an 1 1 mixture of both in varying concentrations (E/S = 1 - 4%). During hydrolysis, 100 ml samples were drawn and rapidly heated to 90°C to inactivate the enzyme. DH of each sample was determined (11) and the viscosity was measured in... 

The viscosity of the gelatin hydrolysates was measured directly on the samples. 

The picture is somewhat different if we consider an inhomoge-nous system such as soy protein hydrolysate. Figure 10 shows that the viscosity as a function of DH is characterized by a sudden, initial large drop between DH = 1% (control sample) and the hydrolysates with the lowest DH-values. No further drop in viscosity is observed when DH is 3% or above. The figure also shows that the final level of viscosity seems to be dependent on the enzyme rather than on DH which is in marked contrast to the results obtained with gelatin hydrolysates (Figure 9). 

Colloidal isotonic solutions of macromolecules include dextrans (glucose polymer), gelatin (hydrolysed collagen) and hydroxyethyl starch. 

Immediate-release formulations typically consist of the drug substance, fillers such as mannitol and lactose and binders such as gelatin, gelatin hydrolysates, and polyvinylpyrolidone. Cross-linked biopolymers based on collagen derivatives are used for sustained-release pellets. See Refs. ° for a detailed discussion on the formulation and processing variables.
