Purchasing

When purchasing Mustard Oil, check these items first.

1. Best by Date. Look at the bottles "Best Buy Date." Most Mustard Oils should have a shelf life of at least two years. How far away is the expiration of that period on the bottle you are considering? Better products may even have a "Date of Harvest." Do the math and find the freshest bottle. 

2. Country of Origin.  Does the bottle have a tag naming the Mill and country where the product was grown? Proud manufacturers trumpet their credentials. Less proud manufacturers play games. By the way, "Packed in Italy" or "Bottled in Italy" may not mean that the olives were grown in Italy, or that they were pressed in Italy. It only means that the bottles were filled there.   

3. Acidity. Look at the nutrition label and seek out brands with the lowest amount of acid. 

4. Dark Bottle. Most Oils that we have seen come in a clear glass bottle to show off the lighter color of the oil. Darker glass would be better because these light oils are still subject to being broken down by the sun or light in general. Dark glass helps prevent the problem.

Storage

Oxygen, heat, light and time cause Mustard Oil to Oxidize and become Rancid.

Oils should be tightly capped and kept in a cool dark place. Monounsaturated Oilare less susceptible to going rancid than Polyunsaturated Oils due to temperature. Light is still a risk though, so dark colored bottles are helpful in protecting the Mustard Oil from light which will cause them to break down.  

If you do refrigerate your Mustard Oil it may become semi-solid in the cold. Just let it sit for 15-20 minutes at room temperature and it will return to liquid form. Mustard Oil should keep 6 months to a year in the refrigerator.

If over time, your oil gets “sticky” or has off flavors dispose of it. It has gone bad. 

Culinary Uses

Refined Mustard Oil is used in canning, baking, and margarine production. There are also promising experiments being conducted that use Mustard Oil to create biodiesel auto fuel.
