Soy & Peanut Oils

Glycine max
part of: Soybean

Soybean oil is one of the most widely consumed vegetable oils in the world. It has a neutral flavour and a relatively high smoke point, making it suitable for frying, sautéing, baking, and salad dressings. Peanut oil, often grouped alongside it in blended products, adds a slightly nuttier character and is especially popular for deep-frying and in Asian cooking.

These oils are kitchen workhorses rather than finishing oils. You’ll find soybean oil as a base ingredient in many commercial products — margarine, mayonnaise, snack foods, and salad dressings — often listed simply as “vegetable oil” on labels. Peanut oil is more commonly used on its own, particularly for wok cooking and deep-frying where its stability at high temperatures is valued.

Blended soy and peanut oils offer a balance of affordability and performance. If you’re cooking for someone with a peanut allergy, always check labels carefully, as refined peanut oil may still pose a risk for highly sensitive individuals.

Safety

  • Toxicity: Contains trypsin inhibitors. Requires preparation.

How it's made

Soybeans are cleaned, cracked, and rolled into flakes before the oil is extracted, typically using a solvent such as hexane. The crude oil is then refined through degumming, neutralisation, bleaching, and deodorising to produce the clear, mild-tasting oil sold in shops. Peanut oil follows a similar process — roasted or raw peanuts are mechanically pressed or solvent-extracted, then refined. Cold-pressed versions of both oils retain more of their original flavour and colour but have a lower smoke point.
