1. Food Preservation and pH

    Sometimes people preserve fruits by adding water, sugar, and some spice to make a fruit preserve, and then putting the preserve in a tightly sealed jar. But when fruit preserves are stored in a warm place, they start fermenting, which is a chemical breakdown by microorganisms like bacteria, and they get sour. What does this process have in common with the souring of milk?
