Gelatin was extracted from the skin of tilapia (Oreochromis urolepis hornorum) and characterized according to its physical and chemical properties. It had pH 4.66, which is slightly higher than the values reported for gelatins processed by acid solubilization. In general, the ionic content was low, and the average yield of the process was 5.10 g/100 g. The proximal composition of the gelatin was similar to that of the commercial gelatins, with slightly higher moisture content. The tilapia skin gelatin had whitish-yellow color and average turbidity of 67 NTU

Summary This study aimed to characterize propolis with respect to its antioxidant activity and apply it to the elaboration of Italian-type salami. A propolis sample was collected and subjected to chemical and physicochemical characterization and its antioxidant capacity determined. Four salami formulations were developed: F1 (no antioxidants); F2 (addition of 0.01% BHT); F3 (addition of 0.01% propolis) and F4 (addition of 0.05% propolis). The salamis were evaluated with respect to their physicochemical properties and lipid oxidation. The characterization of the propolis showed a high level of waxes and low levels of phenolic compounds and flavonoids, although in sufficient quantity to prove their antioxidant activity. The Italian-type salamis showed moisture, protein and lipid contents which conformed to the limits preconized by Brazilian legislation. The F4 formulation (0.05% propolis) showed a better result when compared to the formulations F3 (0.01% propolis) and F1 (no antioxidant). However, formulation F2 (0.01% BHT) showed the lowest value of lipid oxidation. The results showed that propolis inhibits oxidative action and can be added to meat products as a natural antioxidant.

Fish bones are important sources of collagen and are usually discarded by the processing industries. A response surface methodology was utilized to optimize the extraction process of gelatin from king weakfish (Macrodon ancylodon) bones submitted to alkali pre-treatment. The experimental responses were gel strength and gelatin yield, while the studied variables were sodium hydroxide concentration (2 and 4 g/100 g), maceration time (48 and 72 h) and extraction temperature (60 °C and 80 °C). An increase in extraction temperature carried out a significant (p ≤ 0.05) reduction in gelatin gel strength. The increase in the NaOH concentration during maceration increased the process yield. Extraction temperature, NaOH concentration and their interaction had a pronounced effect on process yield. High extraction temperatures resulted in higher yields, but reduced the strength of gelatin gel.
