Recent Trends of Cashew Nutshell Liquid: Extraction
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.
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.
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.
Cashew nut shell, a by-product of the cashew industry, is an embodiment of a useful chemical serving as a raw material for the petrochemical industry. Cashew ( Anacardium Occidentale L.), a well-known species of the Anacardiceae family [ 1 ], is a tropical plant (shrub) found within the region between 23 ° N and 23 ° S of the equator.
Cashew nutshell liquid and its derivatives in oil field
of CNSL, and the extraction efficacy differs with the method employed. It has been estimated that the raw 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.
Compared with mechanical extraction (Rodrigues et al., 2011) and thermal extraction, high yield of more stable non-polymerized CNSL can be obtained by fully contacting crushed cashew nut shells with solvent or supercritical carbon dioxide (Mubofu and Mgaya, 2018). Subsequent treatment is also relatively uncomplicated without separation due to
Utilizing cashew nut shell liquid for the sustainable
An estimate of 3.3 kg of cashew nut shell is needed to make 1 kg of CNSL and approximately 20% of the nutshell oil is found in raw cashew nut (Kumar et al., 2018). Other approaches, such as pyrolysis, the use of supercritical carbon dioxide, supercritical water, and ultrasonication, can be used to obtain CNSL from the nut (Ike et al., 2021
The results of the physical analysis showed that the cashew kernel oil (CKO) is light yellow while the Cashew Nut Shell Liquid (CNSL) is dark brown. The boiling points for shell and kernel oil
[PDF] Extraction and Characterization of Cashew Nut
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
100 times the mass of oil extracted by mass of cashew nut introduced into the extraction column. c. Considering 10.05 % of moisture in the initial sample. d. 100 times the percentage of oil extracted at the end of the total extraction time by the percentage of the oil extracted with ethyl ether and petroleum ether.
