Potassium Stearate (PS) - E 470a

Potassium Stearate (PS), designated as the food additive E 470a, is a highly functional compound utilized as an emulsifier, water retention agent, gelling agent, and pH regulator. It appears as a white cream powder.Key Functions and BenefitsPotassium Stearate's efficacy stems from its multi-functional properties, which are leveraged to control texture, stability, and flow:

• Cake Emulsification Systems: It is used within cake emulsifier blends for its critical role as a pH regulator, water-retaining agent, and gelling agent. By raising the product's pH value, it facilitates the formation of a necessary solid structure, aiding in aeration and stability.• Creams and Thickening: In creams, its pH-regulating and thickening properties are employed to bring the product to the desired, consistent texture.• Sauce Stabilization: In sauces, it contributes to stabilization through its surface tension-increasing and thickening properties, which effectively prevents the product from releasing oil and water (phase separation).ApplicationsPotassium Stearate is predominantly used in food systems where stability, controlled texture, and pH management are essential:• Bakery Systems: Cakes• Dairy: Creams• Dressings: Sauces
