Читать книгу Canning & Preserving For Dummies - Amelia Jeanroy - Страница 15

Canning is the most popular preserving method used today. Don’t let anyone tell you that home-canning is complicated and unsafe. It’s simply not true. Canning is the process of applying heat to food that’s sealed in a jar in order to destroy any microorganisms that can cause food spoilage. All foods contain these microorganisms. Proper canning techniques stop this spoilage by heating the food for a specific period of time and killing these unwanted microorganisms. Also, during the canning process, air is driven from the jar, and a vacuum is formed as the jar cools and seals. This prevents microorganisms from entering and recontaminating the food.
