How to accurately control the amount of Phosphoric Acid PA added in food processing?
Although Phosphoric Acid PA can adjust acidity and improve flavor in food processing, if the amount is not added properly, it will damage the quality of food. In beverage production, if it is used as an acidity regulator, if too much is added, the sour taste will be too strong and the taste will be sour and difficult to swallow; if too little is added, the expected flavor and antiseptic effect cannot be achieved. Generally speaking, the amount added is often 100 grams per 100 liters of beverage, but the specific amount needs to be finely adjusted according to the type of beverage, sugar content and target taste. In meat processing, when used for quality improvement, too much addition can easily make the meat soft and rotten, and too little addition can hardly play the role of water retention and tenderization. It is usually measured in a few thousandths of the weight of the raw material. Controlling the amount of addition is like cooking seasoning. It requires a deep understanding of the physical properties, repeated adjustments according to food characteristics, process requirements and expected effects, and accumulation of experience to achieve accuracy and make the food flavor excellent and of high quality.
What are the key points to pay attention to when storing Phosphoric Acid PA?
When storing Phosphoric Acid PA, both the environment and container selection are key. Because it is corrosive, it is advisable to choose a dry, ventilated and cool dedicated warehouse, away from fire, heat sources and flammable and explosive items. It must not be stored with alkaline substances and metal elements to prevent violent reactions. The warehouse floor needs to be treated with anti-corrosion to prevent acid leakage and corrosion of the floor. Special plastic barrels or ceramic jars are often used as storage containers. They must have good sealing and corrosion resistance. Before use, carefully check whether the container is damaged or leaking. During storage, regularly check the condition of the container and the quality of the acid to observe whether there are any abnormalities such as discoloration and turbidity. In case of high temperature weather, it is even more important to strengthen ventilation and cooling of the warehouse to avoid increased volatilization of the acid. Only by properly storing it in this way can we ensure that Phosphoric Acid PA is stable in nature and safe to use.
What are the advantages and disadvantages of common methods for preparing Phosphoric Acid PA?
There are two common methods for preparing Phosphoric Acid PA: thermal method and wet method. The thermal method uses yellow phosphorus as raw material, which is obtained by combustion and hydration. Its advantages are high product purity and few impurities, and it is suitable for fine chemicals, food and other industries with strict purity requirements. However, this method consumes a lot of energy, yellow phosphorus is a hazardous chemical, the production process has high safety risks, and the cost is expensive. The wet method uses phosphate rock as raw material, reacts with sulfuric acid, and is extracted and purified. Its advantages are that the raw materials are easy to obtain, the cost is low, and it is suitable for large-scale industrial production. However, the product obtained by this method has relatively low purity and more impurities, and subsequent complex purification treatment is required. In addition, a large amount of waste slag and wastewater will be generated during the production process, which has a great impact on the environment. Both methods have their own advantages and disadvantages. In actual production, it is necessary to comprehensively consider factors such as raw material supply, product quality requirements, cost budget and environmental protection standards, and carefully choose to achieve the best production efficiency.
What are the taboos for mixing Phosphoric Acid PA with other chemicals?
Mixing Phosphoric Acid PA with other chemicals can cause trouble if you are not careful. Because it is a strong acid, it is strictly forbidden to mix with alkaline chemicals. When the two meet, it is like cooking oil with a raging fire, and violent neutralization will release a lot of heat, which may cause splashing, explosion and other dangers, and will reduce the effectiveness of each other. It is also not advisable to mix with metal elements. It is easy to cause displacement reaction and produce hydrogen. There is a risk of explosion when encountering open flames or heat sources. In addition, strong oxidants mixed with Phosphoric Acid PA may cause redox reactions, resulting in changes in the properties of chemicals and even the generation of toxic and harmful products. Before mixing, be sure to understand the properties and reaction characteristics of each chemical in detail, or conduct small-scale tests, just like a counselor making a plan, to ensure that there are no adverse reactions before mixing. Do not operate blindly, so as not to cause a disaster, endangering personnel safety and production stability.
How to do safety protection when using Phosphoric Acid PA?
When using Phosphoric Acid PA, safety protection is the top priority. Operators must wear corrosion-resistant protective clothing, acid-resistant gloves, protective masks and goggles, and wear full body protection to prevent acid from contacting the skin and splashing into the eyes. During operation, keep the workplace well ventilated, such as a wide building to let in wind, and disperse the volatile acid mist in time. If you accidentally come into contact with acid, immediately rinse the injured area with plenty of water for at least 15 minutes, such as flooding, and then seek medical attention as soon as possible. During storage and transportation, follow the relevant regulations on hazardous chemicals, use special containers and transportation tools to prevent leakage. The workplace is equipped with emergency supplies such as emergency eyewashers, showers and neutralizers to prepare for emergencies. Use strictly in accordance with the operating procedures, and do not simplify the steps without authorization, so as to ensure personal safety and avoid accidents.
