What is Sodium Alginate & PGA

Sodium alginate, the neutral salt form of alginic acid, is created when sodium ions bind to the carboxyl groups of the alginate polymer.It is soluble in water but it becomes insoluble at low pH or at high concentrations of calcium as alginic acid or calcium alginate are formed.
Propylene Glycol Alginate (PGA), it is made by esterification of the carboxyl groups in alginic acid. It does not gel with polyvalent cations and can be dissolved even in acidic foods, remains stable within a pH range of 3–5, resulting in thickening and stabilizing effects.

Plant-based Meat
In recent years, "plant-based foods" made from proteins like soy have gained significant attention. Originally developed for vegetarians, these products are now also valued for their potential to reduce environmental impact and support a sustainable future.
A standout category within this trend is plant-based meat—products that replicate animal meat using plant-derived proteins. However, unlike animal meat, plant proteins lack natural binding properties when mixed, making it challenging to achieve a meat-like texture.
To create cohesive plant-based products (such as burger patties that mimic ground meat), a high-performance plant-based binder is essential. Alginate, a seaweed-derived ingredient, serves as an ideal solution due to its strong adhesive properties and natural origin, making it a key component in next-generation plant-based meat.

Since gelation of alginate does not require heating and cooling, the process of molding is simple. Molded gelled products are not sticky and easy to handle and can be stored frozen in the raw state. As the alginate gel is heat-resistant, cooking of the molded burger putty does not disrupt its shape. Food texture after cooking can be adjusted by changing the viscosity, M/G ratio or alginate dosage.
