Also, these gelatins can also be used to produce food products which should be stored in the refrigerator, because the mentioned gelatin frozenfreezes at a refrigeratedrefrigeration temperature.
The acid gelatin extraction method is most commonly used for collagen-less absorbency extensions. During the conversion of collagen to gelatin, hydrogen bonds are broken down by heat, it should be noted that the applied heat should be higher than collagen degradation temperature (Joly-Duhamel et al., 2002a).
The acid extraction methods for the preparation of gelatin causes thean increase in the strength of the gel. The rheological properties of gelatin are in fact is theits changing property of gelatin, which depends on the quality of the extracted gelatin from collagen.
The gel strength and melting point of the gel are one of theits most important physical properties of gelatin gel (Badii&Hawell(Badii and Hawell, 2006). Gelling or the point of gel formation is the point inat which the viscosity of the gelatin solution begins to increase with decreasing temperature. The ability of the gel formation is regarded to be susceptible to acid and alkaline hydrolysis. Gelatin is dissolved in water and has the ability in order to form a thermally reversible for gel formation.
