Abstract

This study was conducted to determine the chemical and microbiological properties of commercial liquid milk produced in Laguna. A total of fourteen (14) samples gathered from eight (8) dairy plants were analyzed for fat and protein content for chemical properties and total microbial and coliform load for microbiological properties. Triplicate data was gathered and subjected to descriptive analyses. Result were expressed as mean and standard deviation. The results showed that out of fourteen (14) samples only four (28.57%) has complied with the standard value for fat and only one (7.14%) has satisfied the minimum protein requirement for chemical analysis of liquid milk. For microbiological analyses, six (42.86%) out of fourteen (14) samples tested exceeded the maximum allowed microbial load � cfu/ml (local) and eight (57.14%) exceeded the international standard (� cfu/ml). For total coliform count, nine (64.29%) out of (14) liquid milk samples analysed were negative of coliform bacteria and has satisfied both the national and international standard.
