Description
Magnesium Sulphate – Epsom Salt (E518) for Food & Beverage Processing and Agricultural Crop Nutrition in South Africa
Bidchem is one of the most reliable magnesium sulphate suppliers in Johannesburg, delivering high-performance solutions for both food industry and agricultural applications. Magnesium Sulphate (MgSO₄), commonly known as Epsom salt and classified as food additive E518, is an essential inorganic mineral widely used in food and beverage production as a nutrient supplement, firming agent, flavour enhancer, and processing aid. It supports product stability, improves texture, enhances taste, and assists fermentation processes in brewing, baking, and tofu production.
In agriculture, Magnesium Sulphate supplies two vital nutrients notably magnesium and sulphur, necessary for chlorophyll production, photosynthesis, energy transfer, and nutrient uptake. It is commonly applied to correct magnesium deficiencies in crops, improve yields, enhance foliage colour, and strengthen plant resistance to stress and disease.
As a trusted food ingredient and agricultural nutrient distributor, we ensure this laboratory-tested food-grade mineral meets the rigorous demands of commercial food processing and farming across South Africa. Dispatched daily from our Johannesburg facility, Magnesium Sulphate supports food manufacturers with product development and farmers with essential crop nutrition.

Applications & Uses (Gebruik en Toediening)
Food & Beverage Applications – Food-Grade Mineral (E518)
- Nutritional Fortification: Adds magnesium to mineral water, functional beverages, sports drinks, cereals, plant-based milks, and dietary supplements. Supports calcium–magnesium balance in salt-replacer formulations.
- Food Processing & Fermentation: Supports yeast and microbial activity during fermentation. In brewing and malting, adjusts water mineral composition to improve beer quality. In tofu production, used as a coagulant to produce firm, smooth curds. In baking, promotes consistent dough development and rise.
- Texture & Flavour Enhancement: Acts as a firming agent to maintain crispness in canned vegetables and processed foods. Functions as a flavour enhancer to balance taste profiles in beverages and food products. Serves as a pH stabiliser to regulate acidity and as an anti-caking/drying aid to keep powdered products free-flowing.
- Common Food Products: Mineral water, sports drinks, plant-based beverages, tofu, baked goods, canned vegetables, and dietary supplements.
Agricultural Applications – Magnesium & Sulphur Nutrient
- Chlorophyll Production: Magnesium is central to chlorophyll, enabling plants to convert sunlight into energy.
- Improved Nutrient Uptake: Enhances absorption of phosphorus and other essential minerals.
- Crop Benefits: Improves disease resistance, drought tolerance, fruit development, yield quality, and prevents internal discolouration in crops such as potatoes.
- Soil Health: Balances calcium–magnesium–potassium ratios and improves water and nutrient retention, especially in sandy soils, without significantly altering pH.
- Suitable Crops: Ideal for fruiting vegetables (tomatoes, peppers, cucumbers, potatoes, melons, citrus, grapes), leafy greens (cabbage, lettuce – helps prevent tip burn), and field crops (corn, canola, sunflower where sulphur supports oil synthesis).
- Application Methods: Foliar spray for rapid correction of deficiencies, soil application mixed into soil or applied via irrigation systems, typically during flowering or periods of high nutrient demand guided by soil or leaf analysis.
Agricultural Considerations
- Diagnosis: Apply based on confirmed magnesium deficiency (yellowing leaves, interveinal chlorosis).
- Excess Use: Avoid overapplication to reduce risk of nutrient runoff or water pollution.
- Organic Farming: Verify organic certification requirements before use.
