Palm kernel oil

Palm kernel oil is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Palm kernel oil rather than just read about it. In short: Palm kernel oil is an edible plant oil derived from the kernel of the oil palm tree Elaeis guineensis. It is related to two other edible oils: palm oil, extracted from the fruit pulp of the oil palm, and coconut oil, extracted from the kernel of the coconut.

Key takeaways

Palm kernel oil belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Palm kernel oil to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Palm kernel oil from memory before moving on to harder problems.

Reference excerpt

Palm kernel oil is an edible plant oil derived from the kernel of the oil palm tree Elaeis guineensis. It is related to two other edible oils: palm oil, extracted from the fruit pulp of the oil palm, and coconut oil, extracted from the kernel of the coconut. Palm kernel oil, palm oil, and coconut oil are three of the few highly saturated vegetable fats; these oils give the name to the 16-carbon saturated fatty acid palmitic acid that they contain. Palm kernel oil, which is semi-solid at room temperature, is more saturated than palm oil and comparable to coconut oil.

History

Oil from the African oil palm Elaeis guineensis has long been recognized in West African and Central African countries. European merchants trading with West Africa occasionally purchased palm oil for use in Europe, but palm kernel oil remained rare outside West Africa. The USDA has published historical production figures for palm kernel oil for years beginning October 1 and ending September 30:

Research institutions In the 1960s, research and development (R&D) in oil palm breeding began to expand after Malaysia's Department of Agriculture established an exchange program with West African economies and four private plantations formed the Oil Palm Genetics Laboratory. The Malaysian government also established Kolej Serdang, which became the Universiti Pertanian Malaysia (UPM) in the 1970s to train agricultural and agroindustrial engineers and agribusiness graduates to conduct research in the field. In 1979 with support from the Malaysian Agricultural Research and Development Institute (MARDI) and UPM, the government set up the Palm Oil Research Institute of Malaysia (Porim), a public-and-private-coordinated institution. B. C. Shekhar was appointed founder and chairman. Porim's scientists work in oil palm tree breeding, palm oil nutrition and potential oleochemical use. Porim was renamed Malaysian Palm Oil Board in 2000.

Nutrition Palm kernel oil, similar to coconut oil, is high in saturated fats and is more saturated than palm oil. Palm kernel oil is high in lauric acid, which has been shown to raise blood cholesterol levels, both as LDL-C (cholesterol contained in low-density lipoprotein), which increase the risk of cardiovascular disease, and HDL-C (cholesterol contained in high-density lipoprotein), which has been shown to lower it. However, the raise in total cholesterol concentration is partly due to more HDL-C than LDL-C. Palm kernel oil does not contain cholesterol or trans fatty acids. Palm kernel oil is commonly used in commercial cooking because it is lower in cost than other oils, remains stable at high cooking temperature, and can be stored longer than other vegetable oils. The approximate concentration of fatty acids (FAs) in palm kernel oil is as follows:

Uses

Splitting of oils and fats by hydrolysis, or under basic conditions saponification, yields fatty acids, with glycerin (glycerol) as a byproduct. The split-off fatty acids are a mixture ranging from C4 to C18, depending on the type of oil or fat. Derivatives of palmitic acid were used in combination with naphtha during World War II to produce napalm (aluminum naphthenate and aluminum palmitate).

Worked examples

Example 1 — a first encounter with Palm kernel oil

Start with the simplest possible case. Write down what Palm kernel oil claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Palm kernel oil before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Palm kernel oil ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Palm kernel oil

In research: Palm kernel oil appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Palm kernel oil in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Palm kernel oil is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biofuels, Cooking oils, Oil palm, so understanding it makes those chapters shorter.
In everyday life: Look for Palm kernel oil outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
