Gelatin extracted from jundiá skin (Rhamdia quelen): An alternative to the discarded by-product.

The production of gelatin from by-products of the fishing industry values ​​the discarded raw material and serves a part of the population that does not consume products originating from mammals. Therefore, the objective of the research was to use the jundiá skin (Rhamdia quelen) (JS) to obtain gelatin (GJS) and characterize this product, not yet studied until the present moment. Thus, the extraction process showed a yield of 7.

Banana inflorescences: A cheap raw material with great potential to be used as a natural antioxidant in meat products.

The bioactive compounds and the antioxidant activity of extracts made with various parts of banana inflorescences (bracts, male flowers, rachis, and whole inflorescence) were evaluated in the first part of this study. The extract made with male flowers (EMF) had a higher content of phenolics and flavonoids, lower IC value, and higher FRAP value. Thus, EMF was selected to be used in sausage formulations at the concentrations of 0, 0.
