Characterization of Essential Oil Extracted from a Kitchen Waste: Lemon Peel
Fruits and vegetables waste materials and their by-products are generated in great amounts during commercial processing and hence create a severe problem, and are responsible for dangerous effect on surroundings. Therefore, it is very essential to manage them properly. From the earliest age, lemon essential oil (EO) has been usually used for their fungicides, bactericidal, insecticides, anti-parasitical, healing and cosmetic proprieties. The present research is performed to examine the resource restoration from lemon peel, a common kitchen waste produced at KUET campus by extraction of essential oil from lemon peel through distillation process and identifying the chemical configuration of EO through gas chromatography–mass spectrometry (GC-MS) analysis. The solid waste (SW) generation rate has been observed as 0.099 kg/capita/day and the amount of lemon peel is the 0.30% of total solid waste. From the study, it has observed that the EO has been found as 2.31% of total lemon peel and lemon peel can be used as air freshener, pest repellent and effective cleaner for glass, ceramics, tiles, and other utensils due to having lots of aromatic, anti–insecticidal, and cleaning compounds presence into lemon peel. From the study, major compounds have been found as limonene (13.21%); Phosphoric acid, tribornyl ester (10.68%); Bicyclo[2.2.1]heptane,7,7-dim ethyl-2-methylene (6.61%); 1,4-Methano-1H-indene,octahydro-1,7a-dimethyl-4-(1-methylethenyl) (3.76%); Squalene (3.19%); Bicyclo[2.2.1]heptan-2-ol,1,3,3-trimethyl-, (1S-endo) (2.52%); 1R-alpha-Pinene (1.48%).
