2.2.1. Headspace gaseous composition and Respiration rate
Headspace gases (O2 and CO2) were measured every day with a
headspace gas analyser (Checkmate 9900, PBI Dansensor Co.,
Denmark) by drawing up 2 ml of air samples. Sampling took
place with a hypodermic needle through a septum pasted on
the packaging film. The CO2 and O2 production rate of
unpackaged control chillies was measured by placing the
chillies in an air tight container (PET jar) and the changes in the
head space were measured using a PBI Dansensor CO2/O2
analyzer
