Summary
This study developed curcumin-loaded gelatin/fucoidan electrospun fibers for active food packaging. These materials effectively extend food shelf life by reducing oxidation and inhibiting bacterial growth.
Area of Science:
- Materials Science
- Food Science
- Biotechnology
Background:
- Active packaging extends food shelf life by incorporating functional ingredients.
- Gelatin and fucoidan are biocompatible polymers with potential for food applications.
- Curcumin possesses antioxidant and antimicrobial properties beneficial for food preservation.
Purpose of the Study:
- To develop gelatin/fucoidan (GF) and curcumin-loaded gelatin/fucoidan (CGF) electrospun fibers.
- To evaluate their potential as active packaging materials for food products.
- To investigate the effect of curcumin incorporation on the physicochemical and functional properties of GF fibers.
Main Methods:
- Electrospinning technique was used to fabricate GF and CGF fibers.
- Fourier Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis (TGA) were employed for physicochemical characterization.
- Antibacterial, antioxidant, and food storage tests (9 weeks at 60°C) were conducted to assess performance.
Main Results:
- Optimized GF and CGF fibers exhibited smooth and tubular morphology.
- FTIR and TGA confirmed hydrogen bonding and enhanced thermostability.
- CGF fibers showed significant antibacterial (8-11 mm inhibition zones) and antioxidant (71%) activities.
- GF and CGF materials significantly reduced lipid oxidation in peanuts during storage (lower PV and TBA values).
Conclusions:
- Curcumin-loaded gelatin/fucoidan electrospun fibers demonstrate excellent active packaging properties.
- The developed material effectively inhibits bacterial growth and reduces lipid oxidation in food products.
- This protein-carbohydrate composite incorporating a bioactive molecule shows promise for enhancing food shelf life.

03:06Alkali Metals
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

03:01Halogens
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid. Astatine is a highly unstable radioactive element, so currently, most of its properties are unknown due to its short half-life. Tennessine is a synthetic element also predicted to be in this group.
02:58Balancing Redox Equations
Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...
01:29Electrical Transport
The electrical transport property of a material is defined by its resistance and conductivity. Resistance is the measure of a material's ability to resist the flow of electric current, while conductivity gauges its ability to allow the current to pass through, depending on the geometry of the measurement cell, such as electrode spacing and area. Conductivity is measured in Siemens (S). There are different types of conductance, including specific conductance, equivalent conductance, and molar...
01:28Electrochemical Cells
Electrochemical cells are systems that convert chemical energy into electrical energy or use electrical energy to drive chemical reactions. They consist of two electrodes in contact with an electrolyte, where redox reactions enable electron transfer. Most electrochemical cells include two half-cells connected by an external wire for electron flow and a salt bridge for ion flow. The salt bridge contains an electrolyte solution and maintains charge neutrality by allowing ions—not electrons—to...
01:26Applications of EMF Measurements
Electromotive force (EMF) measurements have a broad range of applications in various fields, including chemistry and physics. The electrochemical series, an arrangement of elements in order of their standard electrode potentials, can be determined through EMF measurements. Elements with lower standard potentials can reduce ions of elements with higher standard potentials.The standard cell potential, E°, allows for the calculation of the standard reaction Gibbs energy, ΔG°, and the equilibrium...
