Gel structure aimed at facilitating the replacement of live foods in the early life stages of aquatic organisms

A suitable food supplement for shrimp or fish larvae is presented. The nutritional supplement includes a particulate gel structure with agar, an attractant and water, and an aqueous medium that includes at least one salt. The particulate gel structure can be formed into gelled particles, for example, granules, and gelled particles can be added to the aqueous medium. The invention also relates to a method of preparing the nutritional supplement and a method of co-feeding shrimp or fish larvae with the nutritional supplement and at least one wet or dry food.

Feed additive to increase the ratio of omega-3/omega-6 polyunsaturated fatty acids in aquatic animals

The present invention relates to a feed additive for aquatic animals comprising a combination of capsaicinoid, piperine, gingerol and a selected cinnamaldehyde compound, a curcuminoid and a mixture thereof, and at least one excipient approved for animal feed. The use of a combination with an additive for aquatic animal feed, or with a feed for aquaculture, is also foreseen in order to increase the amount of long-chain omega-3 polyunsaturated fatty acids in total lipids, or to increase the ratio of omega-3/omega-6 polyunsaturated fatty acids in total lipids, or both, in aquatic animals.

Use of fresh frozen seaweed in the preparation of meat substitute products

The present invention relates to the use of freshly frozen seaweed, preferably Himanthalia elongata, for the preparation of a food product. The resulting food product is preferably a meat substitute product with a high amount of seaweed, but with an excellent sensory profile and/or shelf life. The use of freshly frozen seaweed can also give the meat substitute product a nutritional profile with health benefits.

Production and Partial Characterization of Bioactive Compounds Obtained from Underutilized Marine Biological Resources for a Cosmetic Formulation: Evaluation of Cytotoxicity and Bioactivity

In this research, hydrolyzed collagen, glycogen, and hyaluronic acid were obtained through the biotechnological valorization of underutilized marine bioresources. Hydrolyzed collagen was obtained by hydrolysis of blue shark collagen with papain and ultrafiltration. Glycogen was isolated from wastewater from the industrial burning of mussels through ultrafiltration, precipitation, and selective separation of polysaccharides. Hyaluronic acid was produced by fermentation, purification, and depolymerization. The main objective was to test the feasibility of including these three biomolecules in a cosmetic formulation as bioactive compounds.
