Background:

• Inulin is a prebiotic dietary fiber derived from sources like chicory.
• It offers nutritional benefits, including gut microbiota modulation and metabolic health improvements.
• Inulin possesses unique techno-functional properties valuable in food systems.

Purpose of the Study:

• To review the gelation mechanisms of inulin and inulin-based networks.
• To examine how chain length, polymerization, and processing affect gel properties.
• To highlight inulin's applications as a versatile structuring ingredient in food reformulation.

Main Methods:

• Literature review focusing on inulin's gelation properties.
• Analysis of factors influencing inulin gel network formation and stability.
• Exploration of inulin's functional roles in diverse food matrices.

Main Results:

• Inulin forms gel-like networks and emulsion gels through specific mechanisms.
• Gel properties are influenced by inulin's chain length, degree of polymerization, and processing conditions.
• Inulin-based gels serve as effective fat replacers, texture modifiers, and carriers for bioactive compounds.

Conclusions:

• Inulin-based gels enhance structure, stability, and palatability in various food products.
• They facilitate the reformulation of foods with reduced fat and sugar content.
• Inulin's versatility supports sustainable food design and the development of innovative, health-oriented products.
