  Fish gelatin is an important alternative gelatin which can be considered as Halal and acceptable by all religions. It is made from fish by-products of which fish skin is the most widely used part. The collagen and gelatin-like property of fish bones and scales coupled with their readily availability make it a potential source for development into gelatin products. This review discusses the potentials for the development and utilization of fish bones and scales in the production of gelatins. It also looks at the raw materials, processes, properties and the improvement of fish gelatins for future commercial use.

  The goal of this study was to optimize enzymatic hydrolysis of the dark flesh of skipjack tuna (Katsuwonus pelamis). Alcalase 2.4 L® was used as the hydrolytic enzyme at various concentrations (1, 1.5, 2, 2.5 and 3% w/w) at pHs from 6 to 10, temperatures from 35 to 75°C and times of 2 to 6 h. The experiment was performed following a five-level second-order central composite design with six replications at the center points. The high coefficients of determination for degree of hydrolysis (R2 = 0.8909) and free tryptophan content (R2 = 0.9732) indicate the suitability of the design for predicting the responses. The optimum hydrolytic conditions predicted by the response surface methodology were 2% Alcalase® at pH 8.86 and 65.4°C for 5.74 h. These conditions resulted in an experimental degree of hydrolysis of 20.74% and free tryptophan content of 102.23 mg kg-1.
