Flour bleaching is a process that involves the oxidation of flour, which not only whitens its appearance but also enhances its baking performance. Naturally, flour is a yellowish color due to the presence of carotenoids. To achieve a bright white hue, millers employ bleaching agents, which can be either chemical or natural. The most commonly used chemical bleaching agents include benzoyl peroxide, chlorine dioxide, and calcium peroxide. Each of these agents acts by altering the proteins and starches in the flour, resulting in improved dough strength and elasticity.
Beyond the food sector, emulsifiers have significant applications in various industries, including cosmetics, pharmaceuticals, and agriculture. In cosmetics, emulsifiers are essential in the formulation of creams, lotions, and serums, allowing for a smooth and even distribution of oil and water-based ingredients. This ensures product stability and enhances user experience. Additionally, in pharmaceuticals, emulsifiers are used to create stable emulsions for topical applications and oral medications, increasing bioavailability and ensuring effective delivery of active ingredients.
