How does boiling preserve food?
Boiling or blanching food at high temperatures destroys all enzyme activity and almost all microorganisms. The more acidic the food, such as fruit, the more easily microorganisms are destroyed by heat. Boiled preserves must be sealed in airless conditions (e.g. airtight jars) to prolong their shelf life.Click to see full answer. Considering this, what is…
