• Extraction

  Cashew nutshell liquid (CNSL) is extracted from cashew nutshells using a cold maceration method. The cashew nuts were rinsed with water to remove any sand or debris, and then left to air-dry. The nuts were peeled, chopped lengthwise, and macerated. The specific procedure is as follows: 350 g of ground or macerated cashew nutshells were steeped in 2 litres of hexane at room temperature. The mixture was left to stand for 72 hours, with occasional stirring to enhance solvent penetration. After maceration, the extract was filtered, and a rotary evaporator was used to vacuum-separate the solvent from the extracted natural cashew nutshell liquid (nCNSL)^[2]. ;
