What Great Value Peanut Oil 1 Gal is made of, ingredients and materials
Great Value Peanut Oil is refined peanut oil, meaning the crude oil has been processed through degumming, neutralization, bleaching, and deodorization to remove impurities, allergens, and off-flavors. This refining process removes most naturally occurring compounds that could degrade or cause rancidity. Refined peanut oil is chemically stable at typical cooking temperatures and has a high smoke point (around 450F), making it suitable for frying, sauteing, and baking without breaking down into harmful compounds.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Oxidative degradation (rancidity)
Any refined peanut oil can oxidize over time if stored in warm, bright, or humid conditions, producing peroxides and free radicals that are harmful when consumed. Proper cool, dark storage and timely use minimize this risk.
Heat-induced toxic compounds (aldehydes, trans fats)
Heating any oil, including peanut oil, above its smoke point for extended periods can produce aldehydes and other volatile compounds. Peanut oil's high smoke point (450F) makes this less likely than with lower-smoke-point oils if used correctly, but overheating is a user behavior risk, not a product defect.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Aflatoxin contamination
Refining processes used in commercial peanut oil production remove or destroy aflatoxins that may occur in raw peanuts; no recalls or contamination reports are documented for Great Value peanut oil specifically. This hazard is effectively controlled in any legitimately refined product.
Cross-contamination or undisclosed allergens
Refined peanut oil is not required to carry peanut allergen warnings in the US because refining removes peanut proteins; no documented cross-contamination recalls exist for Great Value. However, label does not explicitly state whether facilities handle tree nuts or peanuts, so those with severe allergies should contact manufacturer for assurance.
How is this PFAS grade calculated?
The brand's record and disclosure
Great Value is Walmart's private-label brand and sources this oil through standard commodity supply chains; no specific quality certifications, third-party testing disclosures, or documented contamination recalls are on public record for this product. Walmart does not publish ingredient traceability or manufacturing facility details for this line. The product carries no organic, non-GMO, or verified purity claims, indicating standard commodity-grade refinement and testing protocols.
How it compares in its category
Refined peanut oil has lower concern for aflatoxin risk (a concern in poorly stored raw peanuts) and lower levels of plant-derived contaminants compared to unrefined peanut oil, because refining reduces these contaminants. Compared to unrefined or cold-pressed peanut oils, refined versions have no odor or flavor compounds that can oxidize, and compared to canola or soybean oils, peanut oil has a higher smoke point and slower oxidation rate. Great Value's commodity-grade refinement aligns with industry standard for budget retail oils; it lacks the certifications or traceability of premium or organic brands but carries equivalent safety for routine cooking use.
If you buy it
Store in a cool, dark cupboard away from heat and light to slow oxidation; an unopened 1-gallon bottle typically remains stable for 1-2 years. Do not heat beyond 450F (240C) to avoid creating oxidation byproducts; use for sauteing, shallow frying, and baking but not deep frying at very high temps. Once opened, decant into smaller, airtight dark bottles if storage extends beyond 6 months to minimize air exposure. Discard if oil develops off-odors, cloudiness at room temperature, or signs of rancidity.
