| Abstract:
Kaffir lime (Citrus hystrix) is one of the important medicinal herbs used in Thailand’s traditional medicine. Kaffir lime and its derivatives, including kaffir lime juice, kaffir lime peel and kaffir lime oil provide a whole range of medicinal properties. Kaffir lime oil, the main aromatic oil from peel, is comprised of betapinine and d-limonene. D-limonene has been suggested to have cancer-chemo-preventive and anticarcinogenic properties, making it a potential candidate for use as a medicinal herb. Moreover, kaffir lime oil possesses tyrosinase inhibition activity, giving it a high potential for cosmetic use. The main objective in this study was to investigate clean production of freeze-dried kaffir lime powder, focusing on waste utilization resulting in a whole range of commercial utilization for medicinal herb and cosmetic use including spa and aromatherapy. Technology has already been developed in which freeze-dried kaffir lime powder retains the same quality of fresh kaffir lime juice. Freeze-dried kaffir lime powder processing in this study include kaffir lime powder processing, kaffir lime oil extraction, kaffir lime peel processing and kaffir lime seed processing. The designed production process has considered the wastes from kaffir lime powder production, which has been divided into three sequential processes. The first one is kaffir lime oil extraction from the peels (exocarp) through squeezing oil from the kaffir lime peels followed by steam extraction and drying for spa and aromatherapy. The second process is Kaffir lime endocarp drying and grinding into powder or cut into small pieces for spa. The third process is kaffir lime seed grinding followed by drying for biopesticide. The residues from steam extraction and other wastes from the extraction process can be used as bio-fertilizers. The result showed zero discharge by the end of the process. The clean production processing of freeze-dried kaffir lime powder has been implemented by the Production Services Unit, Industrial Park, KMUTT. The processing results showed that from one ton of kaffir lime fruit 80 kg of kaffir lime juice, 16 kg of kaffir lime seed, 300 kg of kaffir lime peel and 604 kg of kaffir lime endocarp are obtained. The 80 kg of kaffir lime juice produced 13.5 kg of freeze-dried kaffir lime powder, 300 kg of the kaffir lime peel produced 6 L of kaffir lime essential oil and 160 kg of dried ground kaffir lime exocarp, 16 kg of kaffir lime seed produced 12 kg of dried ground kaffir lime seed as biopesticide, 604 kg of kaffir lime endocarp produced 240 kg of dried kaffir lime endocarp. The results showed high productivity and low environmental impact with this freeze-dried kaffir lime powder processing. Product development for cosmetics, spa and aromatherapy are ongoing study. | |
