The Importance of Water Treatment
Phosphoric acid is primarily produced through two methods the wet process and the thermal process. The wet process involves reacting phosphate rock with sulfuric acid, resulting in phosphoric acid and calcium sulfate. This method is widely used due to its cost-effectiveness and efficiency in generating high-purity phosphoric acid. On the other hand, the thermal process involves high-temperature reactions between phosphorus trioxide and water, yielding phosphoric acid. Although this method produces higher purity acids, it is less common due to its higher production costs.
Consumer awareness regarding food ingredients is on the rise, leading to a growing trend for natural and organic foods. This shift has prompted many food manufacturers to seek alternatives to traditional preservatives like sulphur dioxide. Natural preservatives, such as ascorbic acid (vitamin C) and natural extracts with antioxidant properties, are gaining popularity. Additionally, methods like refrigeration, dehydration, and vacuum sealing are being employed to extend shelf life without relying on chemical preservatives.
