Food Grade Thermal Gel, also known as Curdlan Gum, is a polysaccharide extracted through fermentation from carbon sources, nitrogen sources, and trace elements. This versatile ingredient undergoes alcohol extraction, filtration, drying, and crushing processes to produce a fine white powder specifically formulated for food applications.
Structurally, it's a linear glucan composed of D-glucose through β-1,3 glycosidic bonds. What makes it unique is its thermal behavior - forming a low-strength thermoreversible gel at 55°C and transforming into a thermoirreversible gel when heated to 80-145°C. This dual-phase gelation capability makes it invaluable to food scientists and product developers.
The food industry currently accounts for over 80% of thermal gel usage, where it serves multiple functions as a stabilizer, coagulant, thickener, water-holding agent, and film-forming agent. Major applications include:
As plant-based meat alternatives gain popularity, thermal gel plays a crucial role in replicating the mouthfeel and texture of animal proteins. Its ability to create thermostable gel structures makes it particularly valuable for vegan meat, seafood alternatives, and dairy-free products where texture is paramount.
Despite its advantages, the market faces several constraints. Production capacity utilization remains low due to limited global demand relative to manufacturing capabilities. The availability of substitute ingredients like carrageenan and xanthan gum in certain applications creates competitive pressure. Additionally, price sensitivity in emerging markets restricts adoption rates for premium food additives.
Processing challenges also exist - while thermal gel offers excellent functional properties, formulation optimization requires technical expertise to achieve desired textures without affecting flavor profiles, particularly in delicate applications like dairy alternatives.
