In-Situ Measurement of Fresh Produce Respiration Using a Modular Sensor-Based System.

摘要: In situ, continuous and real-time monitoring of respiration (R) respiratory quotient (RQ) are crucial for identifying the optimal conditions long-term storage fresh produce. This study reports application a gas sensor (RMS88) modular respirometer in situ concentrations rates strawberries during lab-scale controlled atmosphere chamber (190 L) Pinova apples commercial facility (170 t). The RMS88 consisted wireless O2 (0% to 25%) CO2 sensors 0.5% 0% 5%). (3.3 L 7.4 apples) leak-proof arrangement with water-containing base plate glass jar on top. Gas were continuously recorded by at regular intervals 1 min 5 and, real-time, transferred terminal program calculate ( R O 2 CO ) RQ. Respiration measurement was done cycles flushing period. A cycle period h up 3 shown be useful under air 10 °C. start anaerobic due low concentration (1%) could real-time. every mean values 1.6 2.7 mL kg−1 h−1, respectively, obtained when (CA) (2% O2, 1.3% °C) established. found rate produce offers great potential incorporated into RQ-based dynamic CA system.
