In the present work, the accumulation of selected toxic and essential ultra-trace elements in fruits of service tree (Sorbus domestica L.) were determined depending on harvest time. Samples were collected from the same sampling area in two different years and within one year in September and October (maturity state). Harvesting the fruits in the same area excludes the influence of metals taken ...

A study was performed to assess volatile and quality changes in stored fresh-cut mangos prepared from ‘‘firm-ripe’’ (FR) and ‘‘soft-ripe’’ (SR) fruit, and to assess what effect passive modified atmosphere packaging (MAP) may have on cut fruit physiology, overall quality and volatile retention or loss. Florida-grown ‘Keitt’ and ‘Palmer’ mangos were used, without heat-treatment. Subjective apprai...

A low-cost sensor array system for banana ripeness monitoring is presented. The sensors are constructed by employing a graphite line-patterning technique (LPT) to print interdigitated graphite electrodes on tracing paper and then coating the printed area with a thin film of polyaniline (PANI) by in-situ polymerization as the gas-sensitive layer. The PANI layers were used for the detection of vo...

Oil palm is an important industry that has contributed to income and support the economic sector especially for Malaysia Indonesia. However, most of equipment in oil still operated manually. This work developed a system separate bunches fruit using color sensors according maturity level. Fruit plays decisive point determining maturity. Here, specific threshold red green blue (RGB) was obtained ...

The purpose of this work was an attempt to monitor the ripeness process and to investigate the different maturity stages of jackfruit by chemometric treatment of the data obtained from the disposable sensor. Response of the sensor strip fabricated using screenprinting technology was analyzed using Principal Component Analysis (PCA) and the classification model constructed by means of Canonical ...

Oil extraction rate (OER) of fresh fruit bunches (FFB) palm oil is depend on the stage ripeness. The process detecting ripeness FFB has difficult by manually. Farmers find it to reach detect with eye, when tree tall. So farmers need a system that able maturity level based color. K-Means method capable clustering closest mean value centroid from number objects cluster k. Data obtained 2 plantati...
