Extraction technique for maximum yield of carotene from crops (carrot)

Abstract

Abstract Carotene from plant could be utilized as the raw material for aromatic compounds synthesis. Since the amount of carotene is limited in plant, the effective technique to obtain as much carotene is need for practical uses. The aim of this study was to obtain an effective method in extracting carotene from carrot. The carotenes obtained will then be used as raw material for the synthesis of aromatic compounds such as ß-ionone and dihydroactinidiolide. The extraction of carotene was conducted by general maceration technique with a non-polar solvent i.e hexane until there was no carotene remains in the sample. As the result, it concludes that the maceration process with ultrasonic assisted extraction could be used to obtain the maximum carotene from carrots. It took 12 times extraction process to extract the maximum yield of carotene from carrots. The maximum carotene extraction is indicated by the loss of the orange color and only leaving a white color in the samples. The result of this study will provide the information about the method on obtaining the carotene from carrot and red sweet potato with maximum yield that could be further utilization.
