Case Study

Sucrose Palmitate as a Bio-Filler for Enhancing the Thermal Stability of Poly(Lactic Acid) Biocomposites for Food Packaging Applications

Valapa R, et al. International Journal of Biological Macromolecules, 2014, 65, 275-283.

Sucrose palmitate (SP) is explored as a novel bio-filler in poly(lactic acid) (PLA) biocomposites, aiming to enhance their thermal stability for food packaging applications. The integration of SP into the PLA matrix effectively decelerates the thermal degradation rate, as evidenced by thermogravimetric analysis (TGA). Up to a 5 wt% loading of SP, the thermal degradation profile of the PLA composites remains similar to pure PLA, with no significant shift in the maximum degradation temperature (Tmax), indicating SP's role as a protective barrier. However, at higher filler concentrations (10 wt%), Tmax shifts to a lower temperature (324 °C), likely due to the increased acidic sites and enhanced degradation rate. Differential scanning calorimetry (DSC) analysis further supports the presence of a unimodal melting peak, confirming the α-crystalline form of PLA. The activation energies of thermal degradation, calculated using Flynn-Wall-Ozawa and Kissinger methods, provide insights into the degradation kinetics of PLA-SP composites. This case study demonstrates sucrose palmitate's potential as an effective thermal stabilizer in biocomposite materials, making it a promising candidate for enhancing the performance of PLA-based food packaging products.

Sucrose Palmitate (SP) as a Plasticizer in Poly(Lactic Acid) (PLA) Nanocomposite Films

Valapa R b, et al. International Journal of Biological Macromolecules, 2016, 89, 70-80.

Sucrose palmitate (SP) is utilized as a plasticizing agent in the preparation of poly(lactic acid) (PLA) nanocomposite films. In a solution-casting approach, PLA was dissolved in chloroform, followed by the addition of SP, with 5 wt% of sucrose palmitate relative to PLA. The PLA-SP mixture was cast onto a Teflon petri plate and dried under ambient conditions before being vacuum-dried at 40°C. The resulting nanocomposite film exhibited a thickness of approximately 60 μm, and further characterization confirmed the structural integrity of the composite. The addition of sucrose palmitate enhances the film's flexibility and processability, positioning PLA-SP composites as a promising alternative for environmentally friendly packaging materials.

Sucrose Palmitate as a Stabilizer in the Formulation of Inhalable Rifampicin-Loaded PLGA Microspheres

Diab R, et al. International Journal of Pharmaceutics, 2012, 436(1-2), 833-839.

Sucrose palmitate (SP) has been utilized as an effective stabilizer in the preparation of rifampicin-loaded poly(lactic-co-glycolic acid) (PLGA) microspheres (RIF-MS) through the oil-in-water (O/W) emulsion-solvent evaporation method.
In brief, the solutions of rifampicin (RIF) and PLGA in dichloromethane, chloroform, or a 1:5 mixture of chloroform and dichloromethane, forming the organic phase, were emulsified in a 50 ml aqueous sucrose palmitate solution for 5 minutes using a Polytron® Homogenizer PT 3100D set at 10,000 rpm, equipped with a 12-mm diameter aggregate-dispersing rotor-stator. Following the formation of the O/W emulsion, the organic solvents were evaporated by either rotary evaporation under reduced pressure (room temperature, 40 mbar) for 15 minutes or by magnetic stirring at 500 rpm at atmospheric pressure for 3 hours. The resulting RIF-MS were then separated by centrifugation at 280 × g for 15 minutes, followed by three washes with purified water to remove any residual surfactant and unencapsulated drug. Finally, the recovered microspheres were freeze-dried using a freeze-drier.
