Cassava as a food

Area of Science:

• Agricultural Science
• Food Science
• Biomass Energy

Background:

• Cassava (Manihot esculenta) is a staple food crop for 300-500 million people worldwide, particularly in South America, Africa, and Asia.
• Cultivated on approximately 11 million hectares annually, it yields about 105 million tons, with over half consumed by humans.
• Its significance as an energy source is highlighted by its use in animal feed, comprising up to 60% of swine diets in European countries.

Purpose of the Study:

• To review the role of cassava as a major global food source.
• To examine its energy conversion efficiency and limitations as a food crop.
• To explore its diverse industrial applications beyond human consumption.

Main Methods:

• Literature review of existing information on cassava cultivation and utilization.
• Analysis of cassava's energy content and production yields.
• Examination of its nutritional profile and post-harvest challenges.

Main Results:

• Cassava is a highly efficient crop in converting solar energy into carbohydrates, yielding up to 3750 kcal per kg of meal.
• Annual production of 15 tons of cassava meal per hectare can generate approximately 56 million kcal.
• Key limitations include low protein content, poor protein quality, and rapid post-harvest root deterioration.

Conclusions:

• Cassava is a crucial energy-providing crop with significant global reach.
• Its industrial applications are extensive, including paper manufacturing, alcohol production, and adhesives.
• Addressing its nutritional deficiencies and improving post-harvest management are key for enhancing its role as a food source.
