ZusammenfassungBerichtet wird über Erfahrungen mit einem neuen Gerät zur Bestimmung der Konzentration von gasförmigem Ethylen (C2H4) in der Luft mit einem elektrokatalytischen Sensor. Das Messprinzip beruht auf der Oxidation von Ethylen zu CO2 und H2O an einer goldbeschichteten Anode mithilfe von verdünnter Schwefelsäure als Katalysator. Die relativ kleinen Ethylenmoleküle setzen sich in die Zwischenräume der Goldpartikel; bei dieser Messung wird daher etwas (ca. 15%) Ethylen verbraucht. Vor… Expand
Sensoren zum Monitoring des Nachernteverhaltens von klimakterischen Früchten

Gold nanoparticles and sensor technology for sensitive ethylene detection
A new electrocatalytic sensor for measurement of gaseous ethylene (C2H4) concentration in air is presented. The measuring principle is based on ethylene oxidation on a gold-Nafion anode with weakExpand
Ethylene detection in fruit supply chains
TLDR
The measurement systems for ethylene are compared with regard to the needs in fruit logistics; i.e. sensitivity, selectivity, long-term stability, facilitation of automated measurement and suitability for mobile application. Expand

TLDR
Monitoring and control of their natural ripening gas - ethylene - is suggested here as one possible key to reducing food waste, which takes into account exogenous ethylene originating from sources other than the fruit itself. Expand
A Colour Ripeness Indicator for Apples
Ripeness and senescence of climacteric fruits are strongly related to the emission of ethylene gas. The ethylene emission of apples can be detected by a new developed ripeness indicator. ThisExpand
