An electronic nose using of MIP (Molecularly Imprinted Polymer) array is developed to give a unique fingerprint of mango volatiles when ripe. Volatiles such as α-pinene, γ-terpinene and terpinolene are found to be released during different stages of fruit maturity. Utilizing these different volatiles, MIPs templates were then synthesized and deposited onto the Interdigitated Electrode (IDE) platform to acquire a specific fingerprint of fruit maturity. It was found that the best composition ratio (Template: MAA: EGDMA) for IDE MIP Sensor is (1:5:20). When exposed to a specific mango volatiles, the IDE-MIP sensor array exhibited a specific sensitivity and high selectivity. These studies provide a potential solution for agriculture sector to improve the quality of harvest.
