EXTRACTION OF ESSENTIAL OILS FROM CASHEW NUTS
Three methods are particularly favoured for extracting cashew nut seed oil (CNSL) from cashew nuts. These are the 3 main methods: thermal, mechanical, and solvent extraction. Extraction of CNSL from shell includes the artisanal method of roasting, thermal-mechanical method(Hot oil bath), steam processing at 270deg C, and quick roasting at 300degC.
Studies on the use of cashew nutshell liquid (CNSL) as a source of raw material for diverse chemical industry applications are well documented. The liquid is extracted from the nutshell and can be further purified to several chemical constituents such as anacardic acid, cardanol, cardol, and 2-methyl cardol.
Cashew Nut Shell Liquid (CNSL) – Properties And Manufacture
The cashew nutshell liquid, popularly known as CNSL, is derived by putting the cashew shells across various extraction methods like expeller, extruder, and solvent. CNSL releases chemical reactions like hydrogenation, polymerisation, epoxidation and many others, which are used in several industrial products, hence of commercial importance.
1. When extracting cashew nut shell liquid from cashew nuts, three basic techniques are typically used. The roasting method, the hot oil bath method, and using a solar cooker are the three options. In addition to removing the corrosive CNSL, roasting also renders the shell brittle, which speeds up the breaking process.
Cashew production benefits and opportunities in Ethiopia: A
On the other hand, the attractive cashew market in different parts of the world is bright for non-growing countries like Ethiopia. Availability of vast land, agroecological suitability, cheap labor, and well-organized agriculture-based institutions in Ethiopia is. a great opportunity for the promotion of cashew production.
cashew nut contains approximately 20% of the nutshell oil. Basically, three main extraction methods have been established for the extraction of CNSL from cashew nuts namely thermal, mechanical, and solvent extrac-tion. Nevertheless, Other methods such as pyrolysis (31–33), use of supercritical carbon dioxide (34, 35),

Exhaustive valorization of cashew nut shell waste as a
However, unlike other solid wastes, the cashew nut shell (CNS) harbour’s a dark brown viscous oil called cashew nut shell liquid (CNSL), located in the soft honeycomb structure found between the
This study was carried out to extract oils from cashew shell and its kernel and to characterize the oils; with the view to ascertain their suitability for consumption and other uses. Soxhlet apparatus was used for the extraction using hexane as solvent. The physical and chemical properties of the extracted oil were analyzed. The percentage oil extracted from the shell of the cashew was found
