Palm oil shortening is a solid, shelf-stable fat made from palm oil that serves the same role as traditional vegetable shortening in cooking and baking. Unlike conventional shortening, which is typically made by hydrogenating liquid vegetable oils (a process that creates trans fats), palm oil shortening gets its firm texture naturally. Palm oil is roughly half saturated fat and half unsaturated fat, which gives it a semi-solid consistency at room temperature without any chemical hardening.
What It’s Made Of
Palm oil’s fatty acid profile is what makes it work as a shortening. About 46% of its fat is palmitic acid (a saturated fat), 5% is stearic acid (another saturated fat), 39% is oleic acid (the same monounsaturated fat found in olive oil), and roughly 9% is linoleic acid (a polyunsaturated fat). That near-even split between saturated and unsaturated fats gives palm oil a melting point around 23°C (73°F), which is right around room temperature. This is why a jar of palm oil shortening holds its shape in your pantry but melts quickly when heated.
Manufacturers can adjust the firmness by separating palm oil into different fractions. Through a process called dry fractionation, the oil is slowly cooled until certain fats crystallize into solids. These solids (called stearin) are then filtered away from the remaining liquid (called olein). The stearin fraction is denser and more saturated, producing a firmer shortening. By controlling how much stearin goes into the final product, producers can make shortenings that range from very soft to very firm, with melting points anywhere from 33°C to 60°C. This process uses no chemicals or solvents, just controlled temperature and physical filtration.
Why It Replaced Hydrogenated Shortening
For decades, the standard shortening on store shelves was made by pumping hydrogen gas through liquid vegetable oils like soybean or cottonseed oil. This hydrogenation process turned them solid but also created trans fats, which are now widely recognized as harmful. Heavily hydrogenated shortening can contain up to 45% trans fatty acids. Palm oil shortening, by contrast, contains zero trans fats because it doesn’t need hydrogenation to be solid. As trans fat regulations tightened around the world, palm oil became the go-to replacement in commercial baking and food manufacturing.
How It Performs in Baking
Shortening’s job in baking is to coat flour proteins, preventing them from forming long gluten strands. This produces tender, flaky textures in pie crusts, biscuits, and cakes. Palm oil shortening does this well because its crystal structure closely resembles that of animal fats like lard and tallow, particularly in lower-melting formulations (33 to 42°C). Higher-melting palm shortenings hold up to 98% of their solid fat content at refrigerator temperatures, making them useful for laminated doughs and frostings that need to stay firm.
You can swap palm oil shortening for butter at a 1:1 ratio by volume, not by weight, since shortening is lighter than butter. Keep in mind that butter is about 80% fat and 20% water, while shortening is nearly 100% fat. This means baked goods made with shortening tend to be more tender and less crisp, and they won’t have butter’s flavor. Many bakers use a blend of the two to get both flakiness and taste.
Shelf Life and Storage
Unopened, palm oil shortening lasts about two years. Once opened, plan to use it within three months for best quality. Store it in a cool, dry spot away from direct sunlight, and keep the container sealed between uses. Exposure to light, heat, and air all speed up the breakdown of fats, which eventually produces off-flavors. Also keep it away from strongly scented foods, as shortening absorbs odors easily. A pantry or interior cabinet is ideal.
Health Considerations
Palm oil shortening’s health profile is a mixed picture. The biggest advantage over traditional shortening is the absence of trans fats, which raise LDL (“bad”) cholesterol and lower HDL (“good”) cholesterol simultaneously. On that front, palm shortening is clearly the better option.
However, palm oil is still high in palmitic acid, a saturated fat linked to elevated LDL cholesterol levels. A systematic review published in PLOS One found that the LDL increase from palm oil consumption compared to other vegetable oils low in saturated fat was “clinically insignificant.” At the same time, high dietary intake of palmitic acid has been associated with a roughly 2.8 times higher risk of heart attack when comparing people who eat the most versus the least. The practical takeaway: palm oil shortening is not a health food, but used in typical baking quantities, it poses less cardiovascular concern than the hydrogenated shortening it replaced.
Sustainability and Sourcing
Palm oil production carries significant environmental baggage, including deforestation in Southeast Asia and habitat loss for endangered species. The Roundtable on Sustainable Palm Oil (RSPO) certifies supply chains from plantation to finished product, verifying that certified palm oil was cultivated and processed according to environmental and social standards. If sourcing matters to you, look for the RSPO certification label on shortening products. Some brands also use “identity preserved” or “segregated” supply chains, which provide stronger traceability than the more common “mass balance” approach.
