Abstract

The effects of temperature, humidity and light on pheophorbide (PB) content in chlorella tablets during storage were studied. Three kinds of chlorella tablets with different chlorophyllase activities were used. PB content increased 2-10 times during storage for 30 days at a relative humidity of 75% at 30°C. The rate of increase of PB was proportional to the chlorophyllase activity in the original chlorella tablet. The increase of PB depended upon the temperature and humidity; light had little effect.
