Question

write a breif note on different methods of food preservation​

Answer 1

➜ Lye also known as Sodium hydroxide turns food alkaline and prevents bacterial growth.

➜ Canning and bottling means sealing cooked food in sterile bottles and cans. The container is boiled and this kills or weakens bacteria. Foods are cooked for various lengths or time. Once the can or bottle is opened the food is again at risk of spoilage.

➜ Jellying is preserving food by cooking in a material that solidifies to form a gel. Fruits are generally preserved as jelly, marmalade or fruit preserves and the jellying agent is pectin that is naturally found in fruit. Sugar is also added.

➜ Potting is a traditional British way of preserving meat by placing it in a pot and sealing it with a layer of fat.

➜ Jugging is preserving meat by stewing it in an earthenware jug or casserole. Brine or wine is used to stew meat in and sometimes the animal’s blood.
