Quality Control of Fresh-Cut Apples after Coating Application

Area of Science:

• Food Science
• Materials Science

Background:

• Growing demand for ready-to-eat fruits necessitates effective preservation strategies.
• Edible films are crucial for slowing deterioration in fresh-cut produce.
• Coatings require both hydrophilic and hydrophobic properties for optimal performance.

Purpose of the Study:

• To develop and characterize alginate/essential oil nanoformulations for apple preservation.
• To evaluate the efficacy of these nanoformulations in maintaining apple quality during storage.

Main Methods:

• Characterization of alginate/essential oil nanoformulations using dynamic light scattering and rheology.
• Assessment of apple quality parameters: weight loss, pH, titratable acidity, total phenols, and appearance.
• Storage of coated apple pieces at 4 °C.

Main Results:

• Nanoformulations were successfully developed and characterized.
• The low oil content nanoformulation demonstrated significant potential in preserving apple quality.
• Key quality indicators like pH and titratable acidity were favorably maintained by the low oil formulation.

Conclusions:

• Alginate/essential oil nanoformulations show promise for extending the shelf life of fresh-cut apples.
• The low oil content formulation is particularly effective, suggesting tailored formulations can enhance fruit preservation.
• This approach supports the demand for high-quality, ready-to-eat fruit products.
