Mechanistic Insights Into Color and Texture Stability of Frozen Tropical Vegetables: Processing, Modeling, and...

Area of Science:

• Food Science
• Postharvest Technology
• Biochemistry

Background:

• Freezing is crucial for preserving tropical vegetables, but long-term storage causes quality loss.
• Color and texture degradation in frozen vegetables result from biochemical and physical changes.
• Tropical vegetables like taro, okra, and beans are highly susceptible to postharvest deterioration.

Purpose of the Study:

• To review recent research on color and texture stability in frozen tropical vegetables.
• To elucidate the mechanisms behind quality degradation during freezing and storage.
• To identify strategies for improving the quality of frozen tropical vegetables.

Main Methods:

• Literature review synthesizing research on frozen tropical vegetables.
• Analysis of biochemical and physical mechanisms affecting quality.
• Discussion of processing factors (blanching, freezing rate, temperature) and advanced modeling.

Main Results:

• Identified pigment oxidation, enzymatic activity, and ice crystal formation as key degradation factors.
• Highlighted the impact of processing parameters on quality maintenance.
• Reviewed the potential of natural antioxidants, pretreatments, and novel freezing technologies.

Conclusions:

• Integrated understanding of physicochemical changes, microstructural damage, and predictive modeling is limited.
• Further research is needed to link degradation pathways with predictive models for dynamic cold chains.
• Developing comprehensive quality prediction models is essential for the frozen tropical vegetable industry.
