Aluminum hydroxide is an inorganic compound that has antacid properties, primarily used to neutralize stomach acid. By increasing the pH level in the gastric lumen, aluminum hydroxide alleviates the symptoms of acidity and heartburn that often accompany peptic ulcer disease. It works by binding to hydrochloric acid in the stomach, leading to a reduction in acidity, thus providing quick relief from pain and discomfort.
3. Sugar While not a preservative in the traditional sense, sugar plays an essential role in the curing process. It helps balance the flavor and contributes to moisture retention, which is crucial for the texture of cured meats. Additionally, sugar can work in synergy with salt to enhance preservation.
One of the primary reasons preservatives are added to milk is to extend its shelf life. Fresh milk can spoil quickly due to the activity of bacteria and enzymes, which break down its components and lead to off-flavors and spoilage. Among the most common preservatives used in milk are sodium benzoate and potassium sorbate. These compounds are widely recognized for their ability to inhibit bacterial growth, thereby prolonging milk's usability without significant quality loss.
