Simple Home Tricks to Identify Original Groundnut Oil

simple home tricks to identify original groundnut oil

One of the healthiest vegetable oils is original groundnut oil or "peanut" oil because of its high proportion of unsaturated fatty acids compared to saturated ones, which promotes heart health. The relative superiority of authentic groundnut oil in terms of health advantages accounts for its higher price compared to most other cooking oils. Due to the greater customer demand, which makes peanut oil more valuable, there is a propensity to adulterate it with less expensive oils to increase profits of the original groundnut oil price. The harmful effects on health that can result from this adulteration are frequently overlooked while doing so.

Contamination of original groundnut oil is widespread. Even though there are established standards for quality and laws and regulations, adulteration frequently goes unnoticed because of low customer knowledge, inadequate regulatory oversight, and/or mild penalties for violators.

Groundnut Oil: What Is It?

A vegetable-derived oil prepared from the edible seeds of the peanut plant is known as peanut oil, original groundnut oil, or Arachis oil. Although the peanut plant produces blossoms above ground, the peanuts or seeds grow underneath. For this reason, peanuts are often referred to as groundnuts.

The family of legumes that includes peas and beans contains peanuts, which are frequently lumped in with tree nuts like walnuts and almonds. Depending on how it is processed, peanut oil can have a wide range of flavours, from light and sweet to robust and nutty. Although used widely over the world, peanut oil is most frequently utilised in Southeast Asian, South Asian, and Chinese cuisine.

Possible advantages of groundnut oil

Below are some of the possible merits of having groundnut oil in your food.

  • It may lower the risk of heart disease:

Both monounsaturated (MUFA) and polyunsaturated (PUFA) fats, which are abundant in peanut oil, have been widely studied for their potential to lower the risk of heart disease. There has been definite evidence that eating unsaturated fats can reduce some heart disease risk factors.

  • Possible improvement in insulin sensitivity by peanut oil:

According to studies, patients with diabetes may have better blood sugar regulation thanks to monounsaturated and polyunsaturated fats. Any fat consumed with carbohydrates helps reduce the digestive tract's absorption of sugars, which results in a slower rise in blood sugar. Monounsaturated and polyunsaturated fats in particular, though, might have a greater impact on blood sugar regulation.

  • Vitamin E is abundant in groundnut oil:

Additionally, it has been connected to several health advantages, including lowering blood sugar levels in diabetics and lowering some risk factors for heart disease. The term "vitamin E" actually refers to a class of fat-soluble substances that serve a variety of vital roles in the body. As an antioxidant, vitamin E primarily defends the body against dangerous elements known as free radicals.

How is groundnut oil tampered with?

Frequently, cheaper seed oils including cottonseed, corn, rapeseed, rice bran, linseed, and soybean are added to peanut oil to make it taste better. Additionally, castor oil, mineral oil, argemone oil, and Karanja oil are added to make it tainted. It is also possible to adulterate virgin groundnut oil using processed or rancid groundnut oil. To reach optimal colour and flavour, artificial colouring and flavouring chemicals are utilised.

What is the best way to spot contaminated groundnut oil?

  • Evidential detection

On occasion, looking at the oil is all it takes to detect adulteration. Any foreign material found there, including dirt, black particles, sediments, and even turbidity, is adequate proof that the groundnut oil is of poor quality.

  • Traditional technique:

The freezing points of various oils are the foundation of the traditional approach for determining adulteration. When the sample is chilled, the various oils' variations in absorbance can be seen. The absorbance value of the original groundnut oil decreases significantly when it is tainted.

  • Verify the information on the packaging:

Some of it can be picked up from how the oil is packaged. Finding a method around the laws and regulations is crucial for adulterators. Thus, if you are familiar with the fundamental guidelines for the packaging of blended edible oils, you can identify those that depart from the guidelines.

  • In December 2018, the FSSAI changed the way edible oils were labelled. Now, blended oils must have the words "Blended Edible Vegetable Oil" on the package, as well as information about the type of oil, its name, and its percentage by weight.
  • Font sizes must follow the rules. The font size for "Blended Edible Vegetable Oil" must be at least 5mm, while the font size for other information must be at least 3mm.
  • Lastly, check the packaging label to see if the combination of oils is also.

The quality of the packing can be inferred by examining whether these straightforward principles have been followed or not.

How could groundnut oil tampering be harmful?

The health advantages of original groundnut oil are numerous. It is beneficial to our hearts to consume a higher proportion of unsaturated fats than saturated fats. Additionally, it possesses features that are anti-inflammatory, anti-cancer, anti-tumour, and anti-diabetic, making it one of the highly recommended oils for cooking.

By changing their chemical makeup, adulteration causes these beneficial aspects of the oil to be diminished or eliminated. Therefore, adulteration either eliminates or reduces the beneficial characteristics of the original groundnut oil. Furthermore, the benefits of pure groundnut oil are actually counteracted if the oil being blended contains more saturated than unsaturated fats.


Due to the increased demand and the resulting profit for manufacturers and dealers, adulteration in edible oil has become a significant source of worry.
