Pre-Cooked Beans for Consumer Convenience

Advanced approach for quick, convenient, and delicious bean

Pre-cooked whole beans are available in dried, canned, and frozen forms, and can be prepared in a short amount of time, ranging from 10 to 30 minutes. This saves a significant amount of cooking time, eliminating the need for soaking and reducing fuel usage. The process of making pre-cooked beans involves sorting, washing, and sizing, followed by passing air and water over the food product. The beans are then blanched at 95°C for 3 minutes, soaked at 45°C for 120 minutes, sterilized and cooked at 97°C for another 120 minutes, and finally dried at room temperature for approximately 24 hours. After this process, the beans are packaged and frozen. Canned beans undergo a similar procedure of soaking, blanching, and cooking, followed by the addition of brine, cooling, canning, and labeling. Both pre-cooked frozen and canned beans can be marketed for both local consumption and export markets.

Problem

Long cooking time, high energy, and water requirements associated with dried common beans discourage their sale and consumption.
Poorer households are discouraged from consuming whole dried beans due to the time, fuel, and water requirements.
Lack of access to nutritious diets among consumers due to the inconvenience of traditional bean preparation methods.
Limited market opportunities and profit margins for farmers and processors in the common bean value chain.

Solution

Pre-cooking combined with canned or frozen preservation techniques substantially decreases preparation time and fuel use, making beans more attractive to consumers.
Pre-cooked beans technology opens up access to higher-value markets, thereby increasing the income of farmers and stimulating demand.
It strengthens the common bean value chain in Sub-Saharan Africa, offering greater marketability and profit margins.
Provides convenience and time savings for consumers, particularly women homemakers and canteen caterers, allowing them to engage in more productive activities.
Reduces cooking costs by 90%, saving energy expenditure for households and conserving forests by decreasing wood and fossil fuel use.
Increases economic opportunities for processors, community-based or cooperative enterprises, and large industrial food manufacturers.
Addresses the nutritional needs of consumers by providing convenient access to nutritious diets, particularly in urban and rural households, schools, armed forces, hospitals, and prisons.
Offers economic benefits for processors, with an internal rate of return of 32% to 53%, leading to positive cash flow in three years.
Promotes responsible consumption practices and contributes to climate resilience through reduced energy consumption and carbon emissions.

Sorting, Washing, and Sizing: The process begins with sorting, washing, and sizing the beans. Air and water are used to pass over the food product to remove impurities.
Blanching: The sorted and cleaned beans are subjected to blanching at 95°C for 3 minutes. This step helps in preserving the quality of the beans.
Soaking: After blanching, the beans are soaked at 45°C for 120 minutes. This process hydrates the beans and prepares them for further cooking.
Sterilization and Cooking: The hydrated beans are then subjected to sterilization and cooking at 97°C for 120 minutes. This ensures that the beans are fully cooked and ready for consumption.
Drying: Following the cooking process, the beans are dried at room temperature for approximately 24 hours. This step helps in removing excess moisture and preparing the beans for packaging.
Packaging and Freezing (for frozen products) or Canning (for canned products): The processed beans are then packaged and either frozen or canned, depending on the preservation method chosen.
