techniques employed in food preservation in Nigeria

 

Food preservation is a crucial aspect of food security in Nigeria. With a population of over 200 million people and a largely agrarian economy, Nigeria relies heavily on food production and preservation to ensure adequate food supply for its citizens. In this article, we will discuss some of the techniques employed in food preservation in Nigeria.

 

Smoking

Smoking is a traditional method of food preservation that is still widely used in Nigeria. Fish, meat, and other food items are hung over a smoky fire and exposed to smoke for a period of time. The smoke acts as a preservative by inhibiting the growth of microorganisms and reducing the moisture content of the food, thus preventing spoilage. Smoked fish, for example, can be stored for several months without refrigeration.

 

Drying

Drying is another traditional method of food preservation that is still widely used in Nigeria. Food items such as vegetables, fruits, and fish are dried in the sun or using other drying techniques such as oven drying. The water content of the food is reduced, making it less hospitable to microorganisms that cause spoilage. Dried fish, for example, can be stored for several months without refrigeration.

 

Fermentation

Fermentation is a process in which microorganisms such as bacteria and yeast break down the carbohydrates in food, producing lactic acid, alcohol, and other compounds. This process can be used to preserve foods such as cassava, maize, and beans in Nigeria. The fermentation process produces acidic conditions that inhibit the growth of spoilage microorganisms, making the food safe for consumption. Fermented foods such as ogi (a type of porridge) and garri (a type of cassava flour) are widely consumed in Nigeria.

 

Canning

Canning is a modern method of food preservation that involves heating food to a high temperature and sealing it in an airtight container. This process kills any microorganisms present in the food and prevents the growth of spoilage microorganisms. Canned foods such as fruits, vegetables, and meat are widely available in Nigeria.

 

Refrigeration and Freezing

Refrigeration and freezing are modern methods of food preservation that are widely used in Nigeria. Refrigeration involves keeping food at a low temperature to slow down the growth of microorganisms, while freezing involves reducing the temperature of food to below freezing point to halt microbial growth altogether. These methods are commonly used to preserve perishable food items such as meat, fish, and dairy products.

 

In conclusion, food preservation is critical for ensuring adequate food supply in Nigeria. Traditional methods such as smoking, drying, and fermentation are still widely used, while modern methods such as canning, refrigeration, and freezing are becoming increasingly popular. By employing these techniques, Nigerians can preserve their food for longer periods, reduce food waste, and ensure food security.
