| Abstract: | "Gulfweed-based edible materials were developed in forms of food film and coating. Gulfweed suspension was subjected to high-pressure homogenization (HPH) at 103, 138, and 193 MPa with 1, 2, and 3 passes, and mixed with 14, 30, 50, and 70% (w/w gulfweed) glycerol and 1% (w/w gulfweed) polysorbate 20 to produce a film-forming suspension. The particle size of the suspension decreased with increasing pressure from 103 to 193 MPa and pass number from 1 to 3. The HPH-treated gulfweed suspension behaved like a pseudo-plastic non-Newtonian fluid. High pressure and pass number generally decreased the suspension viscosity. Uniformity and compactness of the films increased with increasing pressure. The optimal conditions for forming a film with high stretchability, low water vapor permeability, low and water solubility, as well as for preparing bright-colored coated smoked salmon, were found to be 193 MPa, three passes of HPH, and a glycerol concentration of 70%. Coating smoked salmon with gulfweed suspension enhanced the redness without altering its texture and volatile properties. The method reported in this study may be useful for seaweed-based edible film production, increasing their potential application to various food products like red meats. PRACTICAL APPLICATION: Seaweeds have high nutritional and functional values, but they are not commonly used as food materials owing to their appearance and size. Therefore, it is important to develop methods to utilize seaweeds by overcoming appearance and size limitations. A self-standing film/coating using gulfweed was developed in this study, making use of commercially available high-pressure homogenization technology. The method developed herein might enable increased applications of gulfweed and possibly other seaweeds to food products such as films, rolls, or coatings" |
