Microbiological Evaluation of Virgin Coconut Oil (VCO) Production in the Philippines
description Virgin Coconut Oil (VCO) is gaining popularity in recent years because of its beneficial properties that have several applications in food, cosmetics, and medicine. The Philippines is one of the leading exporters of VCO in the world. Some of the most common VCO production techniques in the industry are centrifugation, high-pressure expeller method, and natural fermentation method. To date, there is a lack of studies regarding the microbiology of VCO production. This research aims to determine the microbial quality and safety of VCO collected during production.
