| Research Abstract |
A mathematical model and a computer program for predicting gas concentration change in a package, total CO_2 production and weight loss of the fresh produce, based on respiration and transpiration of the produce, gas permeability of the packaging material and temperature and humidity of the marketing atmosphere, were developed. The validity of the system was confirmed by using the relationship between total CO_2 production and sugar or acid content and between weight loss and relative fruit firmness measured under nine sets of temperature and humidity conditions for citrus fruit.
