Food Additives

Magnesium is a mineral that is necessary for good health.

It’s important for many functions in the body including, regulating muscle and nerve function, blood sugar levels and blood pressure, as well as energy production and bone health.

In addition to its role in several bodily functions, magnesium has important roles as a food additive.

Magnesium carbonate, also known as magnesite, is a naturally occurring mineral. It’s practically insoluble in water and insoluble in alcohol.

It’s produced by mixing magnesium and carbonate ions under an atmosphere of carbon dioxide.1

Magnesium carbonate is widely used as a food additive to prevent caking and as a whitener in food processing applications.

It’s is also used as a demolding agent in the manufacturing of biscuits, as a carbonate source in soft drinks, as well as a source of magnesium in dietary supplements.

Food Grade magnesium oxide, which is odorless and non-toxic, is used as a food additive for powder mix desiccant (drying agent), color retention, pH modification or as a magnesium supplement.

Magnesium oxide adds dietary value in the form of the mineral magnesium in dietary supplements (i.e. vitamins). When added to food products, Marinco also helps control pH and maintain food color.

In addition, Food Grade magnesium oxide keeps powdered foods, such as powder drink mixes, free-flowing as it acts as an anti-caking agent.

Magnesium hydroxide is commercially produced by the metathesis reaction between magnesium salts and sodium, potassium or ammonium hydroxide. It’s insoluble in alcohol with a low solubility in water.

Milk of Magnesia is a brand name for magnesium hydroxide, a product used to treat upset stomach and constipation.

Magnesium hydroxide is widely used as an antacid, laxative and pH regulator in the food processing industry.

Magnesium sulfate, more commonly known as Epsom salts, is prepared from magnesium salts and sulfuric acid.

It’s found in foods such as flour, cheese and confectionary. As a food additive, it’s used to enhance the firmness of canned vegetables.

Magnesium sulfate is also used as a brewing salt in beer production to enhance enzymatic activity or promote a desired flavor profile in beer.
