When potassium sorbate powder is used as a preservative for pastries, potassium sorbate should first be dissolved in water or milk, and then the potassium sorbate solution should be added directly to the flour or dough. When using potassium sorbate powder to preserve starchy food, it is best to acidify the material with a small amount of vinegar first, because potassium sorbate has the best antibacterial and preservative effect when the pH value is lower than 5~6.
potassium sorbate powder can be added to fruit and vegetable juice drinks, carbonated drinks, protein drinks and other beverages. The addition of potassium sorbate greatly extends the shelf life of the product.
