There are many different ways to preserve food, including canning, drying, smoking etc. One of them is smoking. Smoking is a lesser-known process for food preservation. Smoking aids in removing moisture from food, which prevents fungus and bacteria from growing. Extended shelf life is correlated with reduced moisture content. Food gains distinct flavours and intensifies in flavour and scent from smoking. This can improve the food's appeal and aid in the preservation process.
Let us discuss in brief the process of preservation using the smoking technique:
1. Dehydration: Dehydration is the process of removing moisture from food to preserve it for smoking. To impart flavour and prevent bacterial growth, the food is exposed to smoke from burning wood or other materials during the process. Heat from the smoke slowly evaporates the food's water content, keeping it from spoiling. This preservation technique has been used historically for meats, fish, and some fruits since it improves flavour while also extending the food's shelf life.

2. Enhancement of Flavour: As a preservation method, smoking adds a unique smokiness to food, which improves flavour. The object is subjected to wood smoke, which is frequently flavoured with spices or aromatic herbs. This gives distinct flavours that result in a pleasing flavour character. Furthermore, the smoke serves as an organic preservative, preventing microbial development and prolonging the food's shelf life. Smoking is a common way to preserve and improve the flavour of a variety of foods because of the way that heat, smoke, and time interact to increase flavour.
3. Antibacterial Properties: Food is smoked as part of a traditional food preservation technique, which involves burning wood smoke. Through several methods, this procedure gives the food antibacterial qualities. First off, the smoke has substances with antibacterial properties such as organic acids and phenols. Furthermore, smoking causes dehydration, which lowers water activity and limits microbial development. Moreover, smoke can cover food in a protective layer that prevents bacteria from growing there. In general, smoking's antimicrobial qualities add to the safety and longer shelf life of preserved goods.
4. Surface coating: When using smoking as a preservation method, surface coating is lightly dusting the outside of the food with ingredients like sugar, salt, or spices. This coating has several functions, including improving flavour, preventing microbial development, and forming a barrier of defence. The act of smoking food adds a layer of preservation by exposing it to smoke, which includes antibacterial chemicals. When combined, these techniques help to increase the shelf life of smoked goods while giving the preserved goods distinctive flavour profiles.
5. Insect Repellent: Insect repellant is essential to the preservation process when smoking objects since it keeps them safe. Usually, smoke is applied to meats or plants to make the atmosphere unfriendly to insects. The smoke's insect-repelling qualities keep pests away, preventing infestations and maintaining the integrity of the preserved objects. Historically, this technique has been used to increase the shelf life of food and shield it from insect-induced deterioration. This preservation method is made much more efficient by the dual barrier created by the combination of smoke and insect repellent.
Food can be effectively preserved by smoking, but it's crucial to apply the right methods, which include regulating the temperature, time, and kind of wood used. Furthermore, given contemporary food safety regulations, goods that have been smoked might still need to be refrigerated or preserved using other techniques for extended periods.
