PRODUCT OVERVIEW

Product Description

Food Grade C6H7KO2 Series Potassium Sorbate is a white granular food-grade potassium salt of sorbic acid used primarily as a preservative. It helps inhibit the growth and activity of molds, yeasts, and certain microorganisms, supporting product stability and extending storage life while helping maintain the original characteristics of the formulation. Potassium Sorbate is widely used in food and beverage processing, including fruit and vegetable products, processed meat, aquatic products, soy sauce, bakery and dessert products, beverages, and preserved fruit and confectionery applications. The product is supplied as white granules and is evaluated through assay, heat stability, pH, moisture, alkalinity, acidity, aldehydes, heavy metals, and particle-size specifications.
