The most common oils for deep-frying peanuts are peanut oil itself, soybean oil, canola oil, coconut oil, and olive oil. The ideal oils should have a high concentration of monounsaturated and saturated fats, and a low concentration of polyunsaturated fats.

Peanut oil is excellent for deep frying and blends with the taste of peanuts. It, however, contains a relatively high amount of polyunsaturated fats. Soybean oil is also a good choice to fry peanuts as it doesn’t alter their flavor. It also contains a high level of polyunsaturated fats, though. Olive oil and coconut oil are considered the healthiest oils with ideal concentrations of heart-healthy fats. They are great alternatives to peanut oil but are relatively more expensive. Having said that, peanuts are said to improve our hearts longevity according to this study.

One important criterion to consider when making peanuts or peanut products is the aflatoxin levels. Aflatoxins are toxic compounds that can cause disease in humans and animals and are common in peanuts and other food products.

Aflatoxins cannot be completely destroyed by heat treatment or during processing. You must have testing equipment to ensure the aflatoxin levels in your raw peanuts are within safe limits as specified by the regulations before moving forward with any other manufacturing process. You must also specify on your products that peanuts can cause allergies.

Food processing involves many different steps and processing machinery. The same is true for peanut and groundnut processing. Peanuts go through various processing equipment to reach the end consumer. For successful production, specialized peanut processors are used to make this as automated as possible. First, the peanuts are procured from the ground.

After which, they run through separation equipment to remove unwanted particles such as soil remnants and dust particles. Then, the peanuts enter a shelling machine to remove their shells. Once de-shelling has occurred, the peanuts can now enter a gravity separator to get rid of further impurities or left over shells. Separation effectiveness is key to ensuring a quality final product.

The penultimate step is putting the peanuts through a grading machine that separates them according to weight. Finally, further separation occurs after this whereby the nuts are split up by size. If you’re looking to make nut butter then additional equipment and processing will need to take place.
