“…Indeed, films with larger plasticizer content exhibited higher moisture values as compared to those with a lower plasticizer concentration. Other studies (Drakos et al, 2018;Maniglia et al, 2019; F I G U R E 1 Response surfaces for moisture and TS as a function of GF and glycerol, and for solubility as a function of GF and sorbitol Sanches et al, 2021) on flours films observed the same, which was attributed to the hydrophilicity of glycerol.…”

“…Run 1 presented films with a lighter color (lower △E*), which may be justified by the low Cf, Cg, and Cs. Drakos et al (2018) observed in their study that the color of the films was affected by the origin of the flour.…”

“…Therefore, with an increase in the Cg, the TS reduced. The literature reports that the effect of Cg negatively influences TS (Drakos et al, 2018;Sanches et al, 2021). Films produced based on wheat flour had their mechanical properties decreased with increased Cg (Drakos et al, 2018).…”

This study aimed to evaluate the feasibility of the production of sustainable and biodegradable packages made from a little-explored by product of wheat-milling, the glue flour (GF). Films were produced by the casting method and the effect of the incorporation of glycerol, sorbitol, and GF in the properties of the films was investigated following the central composite rotational design (CCRD) approach. The results have been statistically analyzed by the response surface methodology and the desirability function. Due to the rich composition in amylaceous reserve (64.81%; 26% of amylose content), considerable protein content (11.23%), and fibers (8.28%), the GF proved to be suitable for use as a matrix in biopolymer films. All the properties were mainly influenced by the plasticizer type and GF concentration. Film plasticized with glycerol (run 13) was more flexible, had higher moisture (28.39%) content, and was more adhesive than the formulation made with sorbitol (run 11). Film elongation (ELO) ranged from 25.84% to 56.71%, and tensile strength (TS) from 0.10 to 2.8 MPa. The optimized process conditions were 8% for Cf, 0% for Cg, and 4% for Cs. Under these conditions, the films presented low moisture (12.1%), moderate solubility (35.5%) and TS (1.64 MPa), and high ELO (72.06%). This study showed that GF is a promising source for the development of biodegradable films.Practical Application: Films made from a by product of wheat flour (glue flour) have technological potential to be used as packaging for food products. The valorization of a by product of the agribusiness without pre-treatment for the production of biodegradable films was made possible. The study by casting technique is a previous for scale-up production.

“…The particle size and viscosity of film‐forming suspensions are particularly critical factors for the formation of a uniform and even film (Chen, Kuo, & Lai, ; Drakos, Pelava, & Evageliou, ). The assessment of viscosity, which correlates with flow behavior, should be performed at the stage of film‐forming suspension development, because the flow behavior of film‐forming suspensions is a critical factor during the pumping processes in the manufacture of films on a commercial scale (De Moraes, Scheibe, Sereno, & Laurindo, ).…”

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.
