Surface Active Agents01:27

Surface Active Agents

Surfactants, named for their behavior at interfaces, positively adsorb at the interfaces of two phases, reducing interfacial tension. Their versatility as emulsifiers, detergents, and foaming agents stems from this ability. Surfactants, often termed amphiphiles, share the property of amphipathy, with molecules having both hydrophilic and hydrophobic portions. The hydrophilic part is called the head, and the hydrophobic part, including an elongated alkyl substituent, forms the tail.Surfactants...

Area of Science:

  • Food Science and Technology
  • Materials Science
  • Biochemistry

Background:

  • Gelatin films are widely used but often lack mechanical strength and stability.
  • Natural eutectic solvents (NAES) offer potential for improving biopolymer-based film properties.
  • Thymol, a natural antimicrobial, can be incorporated into NAES to impart bioactivity.

Purpose of the Study:

  • To investigate the influence of hydrophobic natural eutectic solvents (NAES) composed of thymol, acetic acid, betaine, and caprylic acid on the properties of bovine gelatin films.
  • To evaluate the mechanical performance, physical properties, stability, and antimicrobial activity of these modified gelatin films.
  • To assess the potential of NAES-based gelatin films for active packaging applications.

Main Methods:

  • Bovine gelatin films were prepared with varying concentrations of NAES (acetic acid, betaine, caprylic acid).
  • Mechanical properties (tensile strength, elongation at break), water vapor permeability, total soluble matter, and swelling were analyzed.
  • Volatility of thymol and NAES was assessed, and antibacterial activity against Gram-positive and Gram-negative bacteria was evaluated.
  • The efficacy of NAES-based films in reducing microbial contamination on chicken breast was tested.

Main Results:

  • NAES significantly enhanced the mechanical properties of gelatin films, with notable increases in tensile strength and elongation at break.
  • Films incorporating NAES exhibited reduced water vapor permeability, lower soluble matter, and decreased swelling.
  • NAES dramatically reduced the volatility of thymol, improving the stability of the active compounds.
  • The developed films displayed significant antibacterial activity, achieving large inhibition zones and undetectable CFU levels for key pathogens on chicken breast.

Conclusions:

  • Hydrophobic NAES effectively plasticize and reinforce bovine gelatin films.
  • NAES-based gelatin films demonstrate improved physical properties and enhanced stability, particularly regarding thymol volatility.
  • These films possess potent antimicrobial properties, making them promising candidates for active food packaging solutions.
  • The study highlights the potential of NAES as functional additives for developing advanced biodegradable packaging materials.
