Pasteurization It is heated in an open vessel to about 60 degree C and then cooled and bottled. Clarification Before bottling, vinegar is made sparkling clear. 1 2 33 Spoilage of Vinegar Lactic acid producing bacteria grow initially and spoil the vinegar. We deliver End-to-End Engineering Design and Construction Management Projects in Food and Beverage Industry PMG Engineering Meeting Global Benchmarks Process Engineering Project Management Food Safety Automation Mechanical & Electrical www.pmg.engineering
