The estimation of ripeness is a significant section of quality determination since maturity at harvest can affect sensory and storage properties of fruits. A possible tactic for defining the grade of ripeness is sensing the aromatic volatiles released by fruit using electronic nose (e‐nose). For detection of the five ripeness grades of berries (whiteberry and blackberry), the e‐nose machine was designed and fabricated. Artificial neural networks (ANN), principal components analysis (PCA), and linear discriminant analysis (LDA) were applied for pattern recognition of array sensors. The best structure (10–11‐5) can classify the samples in five classes in ANN analysis with a precision of 100% and 88.3% for blackberry and whiteberry, respectively. Also, PCA analysis characterized 97% and 93% variance in the blackberry and whiteberry, respectively. The least correct classification for whiteberry was observed in the LDA method.

Fruits produce a wide range of volatile organic compounds that impart their characteristically distinct aromas and contribute to unique flavor characteristics. Fruit aroma and flavor characteristics are of key importance in determining consumer acceptance in commercial fruit markets based on individual preference. Fruit producers, suppliers and retailers traditionally utilize and rely on human testers or panels to evaluate fruit quality and aroma characters for assessing fruit salability in fresh markets. We explore the current and potential utilization of electronic-nose devices (with specialized sensor arrays), instruments that are very effective in discriminating complex mixtures of fruit volatiles, as new effective tools for more efficient fruit aroma analyses to replace conventional expensive methods used in fruit aroma assessments. We review the chemical nature of fruit volatiles during all stages of the agro-fruit production process, describe some of the more important applications that electronic nose (e-nose) technologies have provided for fruit aroma characterizations, and summarize recent research providing e-nose data on the effectiveness of these specialized gas-sensing instruments for fruit identifications, cultivar discriminations, ripeness assessments and fruit grading for assuring fruit quality in commercial markets.

“…Kandungan gas tersebut akan meningkat saat durian dalam kondisi matang. Hal ini sesuai dengan teori bahwa durian memiliki kandungan gas alkohol dan bis(ethylthio)methane yang akan semakin kuat aromanya seiring proses kematangan buahnya [15].Setelah diketahui karakteristik data durian dari data latih dan Tabel 1. Maka selanjutnya menguji data dengan menggunakan metode KNN, yakni data yang baru akan dikelompokkan berdasarkan sebaran data tetangga terdekatnya.…”

Research has been carried out by application of the TGS 2620 (alcohol level) and MQ 138 (methane level) gas sensors to detect the maturity of durian based on Raspberry Pi 3b. This research was conducted to produce a detection instrument for the level of durian maturity. Durian is inserted into the sample room which contain a gas sensors. The classification method used to determine fruit maturity uses K-Nearest Neighbor (KNN). The KNN test in the durian maturity classification using a gas sensor has accuracy based on maturity level, ripe 93,3%; rare 96.6%; raw 93,3%
