The structure and properties of collagen and gelatin
Polimery 2000, No 1, 10
A review with 50 refs. covering the structure of various collagen types, the nature of crosslinking bonds, and the methods for preparing partial collagen destruction products and collagen denaturation proteins, viz., gelatin. Gelatin gel structures are reviewed. Two mechanisms involving the formation of the helical structure while the state of native collagen is being reinstated [35, 36] and two gelling mechanisms are discussed in detail [44,45]. Factors like gelatin origin and composition, concentration of gelatin in the solution, and temperature, which affect the rate of renaturation of gelatin to the collagen form, are discussed.
Keywords: collagen structure, crosslinking bonds in collagen, preparation of gelatin, structure of gelatin gels, mechanism of gelation of gelatin solutions
