Key Micronutrients (per 100g)
- Vitamins:
- Vitamin E (alpha-tocopherol): 17.2 mg (115% DV)
- Vitamin K: 0.7 µg (1% DV)
- Minerals:
- Not a significant source of minerals.
- Antioxidants:
- Predominantly Vitamin E (alpha-tocopherol) and phytosterols. Refined oils may have reduced levels compared to unrefined versions due to processing.
Functional Impact
- Glycemic Index (GI): 0 (As a pure fat, peanut oil does not contain carbohydrates that impact blood glucose directly.)
- Glycemic Load (GL): 0
- Satiety Score: While not directly providing satiety on its own, fat content in meals significantly contributes to satiety and delays gastric emptying, leading to prolonged feelings of fullness.
Physical Properties
- Density: Approximately 0.91-0.92 g/cm³ at 20°C.
- Volumetric Contraction after Cooking: Minimal. Oils exhibit slight thermal expansion when heated and contraction upon cooling, typically less than 1-2% for a given volume within common cooking temperature ranges. This effect is generally negligible for nutritional tracking purposes.

The Manual Tracking Problem with Peanut Oil
Dr. Aria Vance, Lead Nutrition Data Scientist, NutriSnap
Peanut oil. Oh, the irony of a substance so common, so fundamental to countless cuisines, yet so utterly slippery to pin down in any precise nutritional log. A nightmare, frankly. Its history is a rich tapestry, interwoven with ancient Chinese stir-fries and Indian curries, then later becoming a mainstay for deep-frying in the Western world, fueling our obsession with crispy textures. The humble peanut, a legume originally from South America, journeyed globally, eventually yielding this golden elixir that revolutionized cooking. French fries wouldn't be the same without it. This liquid gold, a culinary workhorse, an invisible fat delivery system, is an absolute menace for accurate tracking.
How do you, a mere mortal, precisely quantify that? "A drizzle." "Enough to coat the pan." "Just a splash for flavor." These aren't scientific units, people! This isn't data. When you're making an authentic pad thai or a batch of perfectly crunchy spring rolls, who in their right mind pauses, spatula in one hand, measuring spoon in the other, to meticulously scoop out the exact grams of oil added? Nobody! Not even the most zealous diet tracker. The friction is too high. Spoon measurements are notoriously inconsistent for viscous liquids anyway, due to surface tension playing games with volume. And scales? Yes, weighing the bottle before and after pouring could work, but imagine doing that for every single ingredient, every single cooking step. It's absurd. It undermines the very foundation of accurate dietary analysis, leaving even the most diligent tracker adrift in a sea of guesstimates. Barcodes? Utterly useless for how much was actually used.
We're talking about a nutritional black hole. A significant source of dietary fat, often consumed unconsciously, almost by osmosis. This isn't a problem of missing data, it's a problem of capture. The cognitive load, the sheer tediousness of it, breaks most people. It's why so many diet apps fall short, why our understanding of real-world consumption patterns is so fractured.
Then, a revelation. NutriSnap. A different approach. Forensic visual analysis. Suddenly, that greasy film on the pan isn't just an afterthought. It's data. Our AI models, trained on millions of images, can discern the amount of oil on a surface, within a dish, providing an unprecedented level of accuracy from just a photograph. The era of the "drizzle" is over. Finally, we bring precision to the most elusive of ingredients. It's transformative.
