“…The opacity of the JFP films was evaluated (Pena‐Serna & Lopes‐Filho, ). The absorbance of the JFP films at 600 nm was measured using a spectrophotometer (UV‐2450; Shimadzu Corporation, Kyoto, Japan).…”

Summary The physical, optical, antimicrobial and antioxidant properties of jellyfish protein (JFP) films with added transglutaminase (TGase) and wasabi extract (WE) were studied. Among the plasticisers, 30% sorbitol was the most desirable. The optimal physical properties of the JFP films were obtained when 15 U transglutaminase g−1 JFP was added. The incorporation of WE affected the physical properties of the JFP films. The tensile strength (21.68–35.25 MPa), elongation at break (10.85–13.25%) and Young's modulus (920.18–1278.9 MPa) of the films increased as WE concentration increased from 0.5% to 1.5%. The thermal gravimetric analysis results revealed that the thermal stability of the JFP films increased with increasing concentrations of WE. The inhibition zones against Escherichia coli O157:H7 and Listeria monocytogenes and antioxidant activity also increased as the concentration of WE increased. Thus, antimicrobial and antioxidant JFP films could be prepared by the addition of WE.

“…Determination of the water solubility was carried out in triplicate, based on the method proposed by Pena‐Serna and Lopes‐Filho . Previously dried (105 °C, 24 h) and weighed film disks (2 cm in diameter) were immersed into 50 mL distilled water for 24 h under stirring (76 rpm) at 24 °C in an orbital shaker (SL 222; Solab).…”

“…However, they show some drawbacks inherent to their chemical structure, such as brittleness and hydrophilic character; thus the addition of other components is necessary to improve these properties [4]. In addition to plasticizers such as glycerol, which have shown to improve the flexibility of the films [5][6][7], the use of crosslinkers is also convenient in order to increase water resistance. Aldehydes have been widely known to react with polymers [8], but they are toxic, so natural crosslinking agents are preferred.…”
