Viscosity of the coating was measured using a Brookfield viscometer (Model RVDVI+, Brookfield Eng. Labs Inc., Stoughton, USA). The pH was measured using a microprocessor based pH metre (Model CP931; Century Instruments Private Limited, India). Respiration rate was measured from the regression slope of CO2 concentration versus time data and evaluated as mg CO2 kg−1 h−1 (Maftoonazad and Ramaswamy, 2005). Physiological weight loss of coated and uncoated green chillies were expressed as the percentage loss of initial weight.
