Canning is a Food Preservation technique first derived by

✅Explanation:
-Nicolas Appert, a French confectioner and brewer, is credited with inventing the canning process in 1809. He discovered that food could be preserved by sealing it in airtight containers and heating them. This breakthrough was a significant advancement in food preservation, allowing for the long-term storage and transportation of food.

🔑Key Points:

• Canning:
-The process of sealing fruits and vegetables or any other foodstuffs hermetically (airtight) in containers and sterilizing them by heat for long storage is known as canning. 
-This method of process is useful for extending shelf life.
-Canning typically involves the heating of low-acid foods at 121°C, intending to eliminate all mesophilic microorganisms, as well as spores of Clostridium botulinum, leaving the product 'commercially sterile.'
-This process destroys pathogenic bacteria, kill or control spoilage organisms present, and have minimal impact on the nutritional and physical qualities of the food
-To accomplish this, the process is applied for some time long enough to achieve a 12 log10 reduction in the number of spores of this pathogen (termed '12D processing').
-This usually entails heating for at least 2 min, depending on the food composition. 
-In 1904, Nicholas Appert of France invented this process and he is called as Father of Canning.
-The process of canning is also known as Appertization.

• Annealing:
-This is a heat treatment process that changes the physical and sometimes also the chemical properties of a material to increase ductility and reduce the hardness to make it more workable.
-The annealing process requires the material above its recrystallization temperature for a set amount of time before cooling. The cooling rate depends upon the types of metals being annealed.
-For example, ferrous metals such as steel are usually left to cool down to room temperature in still air while copper, silver, and brass can either be slowly cooled in air or quickly quenched in water.
🛑Additional Information

• Lacquering:
-The process of coating the inner side of the can prevent discoloration of the product is called lacquering.
-Lacquers include oleo-resinous material, synthetic resins, phenolic resins, epoxy resins, and vinyl resins.
-There are two types of lacquers: (a) acid-resistant and (b) sulfur resistant. 

•  Electroplating:
-Electroplating is the deposition of a metal coating onto an object by applying a negative charge to it by immersing it in a solution that contains a metal salt.
-The metal salt contains positively charged metal ions that are attracted to the negatively charged object and are “reduced” to a metallic form on the object’s surface.
-Process of coating a metal object with a thin layer of another metal through electrolysis
