The methods of measuring the bulk density of green tea were investigated to elucidate the relation between volume and weight of packed green tea.<BR>The results are summarized as follows ;<BR>1) It was shown that the bulk densities of green tea measurd by a cylinder having the diameter of 35 m.m. were smaller than the values by a cylinder of the diameter of 52 m.m.<BR>2) The filling method of green tea into the cylinder had the most significant effect on the measurement of the bulk density. The variation of the bulk density in the replicate measurement was greater in the case of loose filling than compact filling.<BR>3) The bulk densities of green tea sold in market showed the values from 0.3 to 0.4g./m.l. in compact filling and those values decreased about 10 to 20% in loose filling.
