Food Grade Epsom Salt vs Epsom Salt

Epsom salt has been used in households for many centuries. It is well known for its countless uses, from soothing baths to gardening. But many of us didn’t know there are differences between food-grade Epsom salt and regular Epsom salt. In this article, we will explore the topic of food-grade Epsom salt vs Epsom salt, their differences, and their impact on our daily lives.

What is Epsom Salt?

Epsom salt, also known as Magnesium Sulphate, is found naturally and is rich in essential minerals. Its chemical composition consists of sulphur, magnesium, and oxygen. Epsom salt is usually known for its health benefits. It is commonly used as a bath salt to relieve sore muscles, but there are many more uses than just bathing.

Types of Epsom Salt

There are two types of Epsom salts: Food-grade and regular. both are different, serve different purposes, and have different standards and regulations.

Understanding Food-grade Epsom Salt

Food-grade salt is generally produced for human consumption and used in the food and beverage industry. When added to food, it acts as a magnesium supplement. It is also used as a coagulant in tofu-making and salt-brewing for beer production. The quality of salt is paramount. Production methods of food-grade Epsom salt follow strict quality standards and eliminate any impurities in the salt.

Understanding Regular Epsom Salt

Regular Epsom salt is similar to food grade, but the purity standards reflect the difference. It is generally used in healthcare for its soothing effects, gardening to enhance soil, and cleaning household products. However, due to its impurities, regular Epsom salt is not recommended for human consumption.

Production and Purity

The manufacturing process is quite similar for both Epsom salts. The difference lies in the purification process. Food-grade Epsom salt undergoes several purification processes to eliminate harmful impurities, making it safe for human consumption. Regular Epsom salt doesn’t undergo extensive purification because it is generally used for external applications only.

Safety Considerations

Whatever food-grade salt we take should be in moderate amounts to avoid adverse health effects. Food-grade Epsom salt is safe for human consumption in moderate amounts. Regular Epsom salt is not recommended for ingestion due to its harmful impurities. Consumption can lead to health effects like digestive issues and the possibility of intoxication.
