Mustard oil can mean either the pressed oil used for cooking, or a pungent essential oil is also known as the volatile oil of mustard. The essential oil results from grinding mustard seed, mixing the grounds with water, and extracting the resulting volatile oil by distillation. It can also be produced by dry distillation of the seed. Pressed mustard oil is used as cooking oil in some cultures, but sale is restricted in some countries due to high levels of erucic acid. Varieties of mustard seed also exist that are low in erucic acid.

In this article, Pritish Kumar Halder discussed Mustard oil, a volatile oil that is extracted from Mustard seeds.

Pressed oil

Oil makes up about 30% of the mustard seeds. It can be produced from black mustard (Brassica nigra), brown Indian mustard (B. juncea), and white mustard (B. hirta).

Mustard oil is extracted from the seeds of the mustard plant (Brassica campestris), belonging to the cruciferous family of plants. It is originally from the Mediterranean regions, but it grows easily in many parts of the world. It has a characteristically pungent flavor and aroma.

Having a distinctive pungent taste, the oil is used for cooking in India, Pakistan, Nepal and Bangladesh. Its pungent flavor is due to allyl isothiocyanate, a phytochemical of plants in the mustard family, Brassicaceae (for example, cabbage, horseradish or wasabi). Mustard oil has about 60% monounsaturated fatty acids (42% erucic acid and 12% oleic acid); it has about 21% polyunsaturated fats (6% the omega-3 alpha-linolenic acid and 15% the omega-6 linoleic acid), and it has about 12% saturated fats.

Potential toxicity

Mustard oil has high levels of erucic acid. Erucic acid may have toxic effects on the heart at high doses. An association between the consumption of dietary erucic acid and increased myocardial lipidosis, or heart disease, has not been established for humans, although given what is known about erucic acid, it is reasonable to expect that humans would be susceptible to this. Mustard oil is not allowed to be imported or sold in the U.S. for use in cooking, except for those products with exceptionally low erucic acid content.

Nutritional information

According to the USDA, 100 grams of mustard oil contains 884 calories of food energy, and is 100% fat. The fat composition is 11% saturated fat, 59% monounsaturated fat, and 21% polyunsaturated fat.

Essential oil

The pungency of the condiment mustard results when ground mustard seeds are mixed with water, vinegar, or other liquid (or even when chewed). Under these conditions, a chemical reaction between the enzyme myrosinase and a glucosinolate known as sinigrin from the seeds of black mustard (Brassica nigra) or brown Indian mustard (Brassica juncea) produces allyl isothiocyanate.

By distillation one can produce a very sharp-tasting essential oil, sometimes called volatile oil of mustard, containing more than 92% allyl isothiocyanate. The pungency of allyl isothiocyanate is due to the activation of the TRPA1 ion channel in sensory neurons. White mustard (Brassica hirta) does not yield allyl isothiocyanate, but a different and milder isothiocyanate.

Allyl isothiocyanate serves the plant as a defense against herbivores. Since it is harmful to the plant itself, it is stored in the harmless form of a glucosinolate, separate from the enzyme myrosinase. Once the herbivore chews the plant, the noxious allyl isothiocyanate is produced. Allyl isothiocyanate is also responsible for the pungent taste of horseradish and wasabi. It can be produced synthetically, sometimes known as synthetic mustard oil.
