Introduction
1.Solubility
- Soluble in cold water, insoluble in hot water: Forms a transparent viscous solution in cold water. When heated to 50–70°C, it gels and redissolves upon cooling, exhibiting thermoreversible behavior.
- pH stability: Stable within pH 3–11, with good acid/alkali resistance.
2. Rheological Properties
- Thickening: Significantly increases solution viscosity, which rises with concentration and molecular weight.
- Pseudoplasticity: Shear-thinning behavior, ideal for applications requiring fluidity (e.g., coatings, sauces).
3. Film-Forming and Adhesive Properties
- Forms flexible, transparent films for coatings or barrier layers.
- Provides moderate adhesion, suitable for adhesives and ceramic green body molding.
4. Water Retention and Stability
- Slows water evaporation (e.g., prevents cracking in construction mortars).
- Resists microbial growth and salt effects, extending product shelf life.
5. Safety
- Non-toxic, odorless, and compliant with FDA, EFSA, and other certifications for food and pharmaceutical use.
Functions and Applications
- Thickening/stabilizing agent: Improves texture in ice cream, salad dressings, etc.
- Plant-based meat substitutes: Mimics fibrous meat structures.
- Low-calorie foods: Provides satiety as a fat replacer.
