To the Editor. Gelatin is a protein derived from collagen and it is obtained principally from cow and pig bones and hides and fish skin.It is a common ingredient in foods such as jellies, sweets, yogurt and frozen desserts.omologous solubilized porcine gelatin inhibited porcine gelatin-specific IgE antibody binding to the solid phase porcine gelatin by 35â85% (Table I). Bovine gelatin was a more effective cross-inhibitor of IgE anti-porcine binding to porcine gelatin allergosorbent (81â94% cross-inhibition).
