A raw cashew nut is a tough, oil-laced shell, while a processed cashew nut is a cleaned, shelled, peeled, and graded kernel. This article follows the nut through processing, explains what changes for the buyers, and shows how to read grades, colour, and forms before you order. Introduction Cashews grow differently from most nuts. The nut hangs outside the cashew fruit, and its shell holds a harsh oil that makes it tricky to handle before anyone can safely eat it. By the time a processed cashew nut reaches your warehouse, it has been steamed or roasted, cracked open, dried, stripped of its skin, and sorted by size and colour. A raw cashew nut has done none of that. It arrives as a tough shell laced with a caustic oil, and it looks and feels nothing like the creamy kernel on a bakery shelf. This article explains what separates the two, what processing does at each stage, and why those steps shape price, handling, and quality. You will also learn how to read grade...
Cashew shells used to be a problem. After the nut was removed, the shell was burned, dumped, or left to pile up. Nobody gave it much thought. But inside that shell is a dark, oily liquid, and that liquid, once processed, turns into one of the most versatile bio-based raw materials available today. That material is Cardanol Oil . Industries that have spent decades relying on petroleum-derived chemicals are now looking at it seriously. Not because it is trending, but because it is beneficial, it is renewable, and the pressure to move away from synthetic phenols is coming from regulators, buyers, and sustainability targets all at once. The global bio-based chemicals market was valued at USD 97 billion in 2023. Cardanol is right in the middle of that shift. Here is a simple, honest look at what it is, what it does, and why more industries are choosing it. What is Cardanol Oil? Cashew nut shell liquid, most people call it CNSL, is pressed or extracted from the shell during cashew processing...
