What do cookies, hazelnut unfold, desserts, cereal bars, pastries, frostings, margarine, and peanut butter all have in frequent?
They (could) include palm oil.
Palm oil has change into a ubiquitous ingredient in lots of meals worldwide. Additionally in locations the place no palm tree will ever develop. The omnipresence of palm oil has led to main environmental & social challenges within the provide chain, leading to packages to handle these challenges (corresponding to RSPO palm oil).
However, why did palm oil change into such a standard oil within the first place?
This submit is sponsored by What’s Palm Oil?. All opinions and experiments are my very own.
Palm oil is a particular oil
Cookies are crispy and brittle, possibly delicate and chewy. Muffins are delicate and fluffy. Frostings are pipeable, peanut butter spreadable. Cereal bars are agency, hazelnut unfold is delicate.
Regardless of their variations, they might all include appreciable quantities of palm oil. Only a few meals substances are as versatile and as wide-spread as palm oil. Different fat, corresponding to butter, olive oil, or lard, usually have extra specialised purposes. You’d use butter in a cake, however not in peanut butter. Olive oil on a salad, however not in a cereal bar.
There are a few causes for this. Firstly, palm oil boasts considerably greater yields in comparison with different oil crops. A single hectare of palm oil manufacturing can produce 4 occasions as a lot oil as the subsequent highest-yielding crops, corresponding to sunflower & rapeseed. It could produce over ten occasions as a lot as among the lower-yielding crops corresponding to olives and coconut.
One other key motive, and the one we’ll give attention to for the remainder of this text, is palm oil’s versatility. Relying on how palm oil is processed, it will probably behave like a liquid oil, or a strong fats. It’s what makes it appropriate for a lot of completely different merchandise.
The vital function of fat & oils in meals
Fats performs a vital function in lots of meals. Ice cream with none fats, or fats replacer, is watery, and thinner. Simply evaluate a popsicle with a scoop of creamy gelato. Cookies with none fats change into dry, like a cracker.
Even the kind of fats or oil you utilize impacts the feel, possibly additionally the colour or taste of your meals. A butter cookie has extra crunch than one made with rapeseed oil. An olive oil chocolate mousse is lighter than one made with cream. A cake made with butter tastes completely different than one made with sunflower oil.
Fats’s habits at particular temperatures is essential
When deciding on a fats, meals producers consider its habits throughout numerous temperatures. Is it strong, liquid, or someplace in between?
For example, if it’s worthwhile to select a fats to make use of in a agency chocolatey product, it have to be strong at room temperature. However, you do need it to soften in your dosing tools, so it flows by means of correctly.
When slicing cookie dough to make cookies, you require a fats that’s agency on the slicing temperature. A liquid fats would make the dough too delicate to slice. Conversely, for a delicate, chewy cookie, you’d desire a softer fats, even perhaps one which’s liquid at room temperature.
When designing an ice cream, you’d desire a fats that doesn’t flip too onerous within the freezer.
From a chemist’s perspective, fats and oils each check with the identical group of substances. They’re each mixtures of triglycerides. Usually, if it’s liquid at room temperature, we name it an oil – olive or sunflower oil as an example (although palm & coconut oil are exceptions). If it’s strong at room temperature, it’s known as a fats, assume lard, butter, or margarine.
Palm oil may be very versatile
So producers want to decide on their oils fastidiously. That’s the place palm oil’s ‘superpower’ is available in: it’s simple to make each liquid and strong merchandise from palm oil.
That is as a result of composition of palm oil. Palm oil incorporates each liquid and strong parts at room temperature. This by itself will not be unusual for fat and oils. Nevertheless, what units palm oil aside is that there’s a large enough distinction between these parts to simply separate them into completely different fractions. Every ensuing palm oil product behaves fairly otherwise.
It’s why yow will discover palm oil in such a variety of merchandise. Builders merely use that ‘half’ of the oil that they should obtain their required product properties.
From orange palm oil to specialised fats
Freshly pressed from the fruit of a palm tree, palm oil is orange. The palm oil will get its orange colour from β-carotene (which turns into vitamin A in your physique), similar to oranges, carrots and tomatoes.
However, most meals that include palm oil shouldn’t be orange. It’s why most palm oil is bleached, to make a colorless fats. It’s additionally filtered to take away impurities and stripped of taste so it doesn’t affect the flavour of merchandise it’s added into. The ensuing oil is impartial and steady, however does include fewer of its unique nutritional vitamins.
The subsequent step is the place the magic occurs. The palm oil is cut up into its completely different fractions in a course of known as fractionation. This course of in and by itself will not be distinctive to palm oil. However, globally, palm oil is by far essentially the most fractionated fats.
From liquid (at room temperature)
On one finish of the spectrum, we find yourself with essentially the most liquid palm oil fraction, known as olein. It has a melting level of 18–20°C. As such, it’s liquid at any temperature above that. You need to use it whenever you want a liquid oil in your product.
To strong
On the opposite finish, you’ll discover a fraction known as tremendous stearin. That is the toughest fats. It’s nonetheless (very) onerous at temperatures under 40–45°C. You want temperatures of 65–70°C to fully soften this fats, making it appropriate for purposes that require more durable fat.
Mixing and matching fractions
In between these two extremes, there are a number of different palm oil fractions. All of them behave just a bit otherwise. By mixing fractions, you’ll be able to create an excellent wider vary of merchandise. This provides producers a variety of oils to select from. They will use the one oil that works finest for them.
Designing meals with palm oil
Meals producers have been on the lookout for methods to ‘design’ fat for many years. Based mostly on dietary tips, they usually desire to make use of ‘wholesome’ fat, the unsaturated type, made out of crops. Nevertheless, inherent to them being unsaturated, and thus wholesome, they’re additionally principally liquid at room temperature – consider olive, sunflower and rapeseed oil.
However, as we mentioned earlier than, for a lot of meals you want a strong fats. Our shortbread cookies would flip right into a puddle if we’d simply use an oil (which we tried, see picture under).
From trans fat to palm
Till not too way back the answer most producers used was to make use of partially hydrogenated fat. These are liquid (unsaturated) fat which have been modified to change into extra strong. The method allowed producers to design the fats with simply the best consistency. Nevertheless, the method of doing so ends in the formation of trans fat.
Over time, it has change into clear that trans fat are decidedly unhealthy for people. So, as an alternative of creating merchandise more healthy by utilizing these strong unsaturated fat, the trans fat made them unhealthier. It’s why, by now, trans fat have largely been banned from meals globally.
However, meals makers nonetheless want these fat with the best habits. That’s the place palm oil stepped in. In lots of merchandise palm oil proved to be an important resolution for this drawback. Identical to partially hydrogenated fat, it may be ‘designed’ to the specified consistency and habits. However, in contrast to partially hydrogenated fat, palm oil doesn’t should be modified. It simply must be separated into fractions. Leading to a trans fats free ingredient.
Palm oil is steady
One other benefit of palm oil is that it is vitally steady. Palm oil is generally strong at room temperature and may usually be saved at room temperature for months, if not years, with out spoiling and oxidizing. The composition of triglycerides in palm oil makes it naturally steady, but in addition the presence of antioxidants corresponding to tocotrienols (a kind of vitamin E).
For comparability, butter, a doable palm oil replacer, must be refrigerated throughout storage. That prices power and cash. It’s another excuse producers could go for a palm oil.
Lastly, palm oil has a extra steady composition all year long, in contrast to different fat corresponding to butter. Butter’s consistency adjustments all year long, because the eating regimen of cows, who produce the milk to make the butter, adjustments as effectively. After all, palm oil is a pure product as effectively, however it’s extra constant, particularly the person fractions.
Sourcing Palm Oil Sustainably – RSPO
The surge in demand for palm oil resulted in main points within the provide chain. As we people are likely to do when there’s a ‘gold rush’, lots of people see alternatives to earn some cash. In consequence, rainforests had been reduce right down to allow the enlargement of palm oil farms and native employees weren’t handled effectively. By now, after these preliminary ‘gold rush years’ a serious world initiative, RSPO (roundtable on sustainable palm oil), has ensured that increasingly palm oil is grown and harvested in a sustainable method, for each the native communities in addition to for the atmosphere.
The proportion of sustainably grown palm oil is rising yr on yr, however globally, lower than half of palm oil has been licensed by RSPO. Use of sustainable palm oil numerous by area as effectively. Europe is the primary importer. On the time of writing (Dec-2023) over 90% of all palm oil imported into Europe is sustainably sourced (RSPO licensed) and thus has not induced deforestation.
Making cookies with palm oil vs. butter
So, what does this appear like in observe? Let’s take a look at some shortbread cookies.
As a shopper, it’s nearly unattainable to get your arms on all these several types of palm oil. Nonetheless, we needed to do a comparability of palm oil versus the fats that’s mostly utilized in baking: butter. So, we baked shortbread cookies with each butter and a palm oil product:
As you’ll be able to see above and under, you’ll be able to bake completely fantastic cookies by changing butter with palm fats. Remember the fact that we simply used whichever palm oil we might get our arms on. Producers have much more selection. They will use the precise proper kind of palm oil for his or her utility. For a tough crisp cookie, they’ll use a more durable fats which supplies that correct amount of crispness. For a softer cookie, they’ll use a unique mix.
As such, cookie builders can actually ‘design’ their cookies the way in which they need.
One other benefit: no want for chilling the dough
When baking shortbread cookies with our palm oil, we observed that we didn’t have to relax the cookie dough, whereas the butter dough did should be chilled within the fridge earlier than slicing it. The palm fats was agency sufficient at room temperature by itself. This generally is a enormous profit for producers. It’d permit them to save lots of on refrigeration tools, saving each prices and power.
All in all, each cookies tasted nice, particularly once we added somewhat trace of vanilla flavoring to make up for the blander palm oil style.
So subsequent time you discover ‘palm oil’ as one of many substances in your product, know that it’s been put there for a particular motive!
