1. The difference between cold-pressed groundnut oil and refined groundnut oil

Cold pressed groundnut oil is produced through cold pressed groundnut oil machines. The general process is: groundnuts are cleaned, crushed, flaked, cooked through groundnuts pre-treatment machines, then physically pressed through groundnut oil cold pressed machines, and finally cold pressed groundnut oil is obtained through a filter.

2. The pros and cons of cold pressed groundnut oil and refined groundnut oil

The cold-pressed crude groundnut oil obtained through the groundnut oil cold pressing machine retains its nutrients and active ingredients intact and has a high protein content. It also ensures that its natural flavor and aroma are retained. However, there are still some impurities in it, such as free fatty acids and pigments, which can cause rancidity and oxidation of groundnut oil. Besides, if groundnuts are not dried sufficiently before processing, they are likely to produce aflatoxin, which is a first-level carcinogen.

Refined groundnut oil obtained through a groundnut oil refining machines destroys the protein structure and the refining process strips the oil of any nutritional value and natural flavor. However, harmful impurities in groundnut oil are removed through refining, effectively improving the color and storage stability of the oil.

3. Is cold-pressed groundnut oil or refined groundnut oil better?

Through the above introduction, you have already understood the difference, the pros and cons of cold-pressed groundnut oil and refined groundnut oil. If you are pursuing the original flavor, cold-pressed groundnut oil is better than refined groundnut oil. For reasons of safety, shelf life and sales issues, refined groundnut oil is better.

The groundnut oil refining machine can filter out aflatoxin, free fatty acids and other impurities, which is safer than cold-pressed groundnut oil. Refined groundnut oil also has a longer shelf life, making it easier to store and sell in large quantities.
