摘要：From the standpoint of effect on keeping quality of milk, the comparison was madebetween low pressure polyethylene can and metal can as milk container. Several trials of storage tests at room temperature (in summer) and low temperature (3°C) were carried out. Analyses were made on acidity, total bacterial count, vitamin C determination, organoleptic observation, and alcohol test. Samples were collected atintervals of 4 hours for 16 hours in room temperature and 24 hours for 120 hours in lowtemperature test, respectively. Data obtained showed that there was no marked difference in effect on keeping qualityof milk between polyethylene can and metal can except for some superiority of theformer in bacterial count and flavor.
