History of cashew nut processing in Africa
The history of cashew nut processing in Africa traces back to the introduction of cashew trees to the continent during the colonial era. Cashew trees, originally native to Brazil, were brought to Africa primarily by Portuguese explorers. The conducive climate of several African regions, particularly in West and East Africa, proved ideal for the cultivation of cashew trees, leading to their widespread adoption.
The initial phase of cashew cultivation in Africa was largely subsistence-oriented, with local communities using the nuts for personal consumption and recognizing their nutritional value. However, as global trade expanded, the cashew industry gained prominence, and commercial cultivation became more prevalent.
During the mid-20th century, there was a significant shift towards cashew nut processing as a means to enhance economic value. African countries began investing in processing facilities to shell, roast, and package cashew nuts for export. This transition marked a departure from exporting raw nuts to exporting processed cashews, contributing to increased revenue and economic development in the region.
Nigeria emerged as one of the key players in African cashew processing, establishing itself as a major exporter of processed cashew nuts. The industry further expanded in countries such as the Ivory Coast, Tanzania, and Mozambique, with governments recognizing the potential for economic growth and job creation through value addition.
Cashew nut processing techniques
Cashew nut processing techniques involve several steps to transform the raw nuts into edible and marketable products. Here is an overview of the key techniques involved, accompanied by a simplified diagram:
- Harvesting: Cashew nuts are harvested once the cashew apples ripen and fall to the ground. The nuts are typically found attached to the bottom of the cashew apple.
- Shelling: Shelling is the process of removing the cashew nut from its hard outer shell. This is a crucial step and can be done manually or using mechanical methods.
- Drying: After shelling, the raw cashew nuts contain excess moisture. Drying is essential to reduce the moisture content and prevent the growth of mold. This can be done naturally in the sun or through mechanical drying.
- Peeling: The cashew nut has a thin outer skin (testa) that needs to be removed before consumption. Peeling can be achieved through roasting, steaming, or using specialized machines.
- Grading and sorting: The processed cashew nuts are graded based on size, color, and quality. Sorting is crucial to ensuring uniformity in the final product.
- Roasting: Roasting enhances the flavor of cashew nuts and also helps in removing any remaining traces of the outer skin. This step can be done using dry or oil-roasting methods.
- Cooling: The roasted nuts are then cooled to room temperature to halt the roasting process and prepare them for packaging.
- Packaging: The final step involves packaging the processed cashew nuts for distribution and consumption. Packaging materials should be chosen to maintain freshness and prevent contamination.
Types of cashew nut processing: Finished products
| Whole cashew nuts | The most basic form of processed cashew is the whole kernel removed from the shell after processing. They are commonly consumed as snacks or used in culinary applications. |
| Cashew kernels | These are the edible parts of the cashew nut removed from the outer shell and testa. Cashew kernels come in different grades based on size, color, and quality, and they are widely used in cooking, baking, and as a standalone snack. |
| Cashew splits | Splits are cashew kernels that have been split into halves. This form is often used in culinary creations where a smaller size or specific shape is desired. |
| Cashew flour | It is produced by grinding cashew pieces into a fine powder, and it is used as a gluten-free alternative in baking or as a thickening agent in certain recipes. |
| Cashew butter | Similar to other nut butter, cashew butter is made by grinding roasted cashew nuts into a smooth paste. It can be spread on toast, used in sandwiches, or incorporated into various dishes. |
| Roasted cashews | Whole or broken cashews that have been dry or oil-roasted to enhance their flavor. Roasted cashews are a popular snack and can be seasoned with various spices. |
| Flavored cashews | Cashew nuts can be coated or seasoned with a variety of flavors, such as honey, spices, or chocolate, to create unique and indulgent snacks. |
| Cashew oil | Extracted from cashew kernels, cashew oil is used for culinary purposes and in cosmetics due to its mild flavor and moisturizing properties. |
FAQs
How do you process cashew nuts in Nigeria?
In Nigeria, cashew nuts undergo a multi-step processing method. Initially, the cashew apples are harvested, and the nuts are extracted from their shells. The nuts are then dried to reduce their moisture content, making them suitable for storage and further processing. Following this, the cashews go through a roasting process, which enhances their flavor and removes any remaining moisture. Finally, the nuts are shelled, graded, and packaged for distribution. This comprehensive process ensures the production of high-quality cashew nuts in Nigeria.
Are cashews hard to process?
Cashews can be relatively challenging to process due to their unique outer shell and the presence of toxic substances. The outer shell contains a caustic resin that can cause skin irritation, making careful handling crucial during processing. Additionally, cashews are one of the few nuts that are not sold in their shells commercially, as the shells contain the aforementioned toxic resin. The careful removal of this outer shell and the subsequent processing steps require precision and expertise to ensure the safety and quality of the final product.
Are cashew nuts really nuts?
Despite the name, cashews are technically not true nuts. Botanically, they belong to the seed family as they grow attached to the cashew apple, the swollen part of the fruit. True nuts, like acorns or chestnuts, have a hard outer shell that encases the seed. In contrast, cashews have a single-seeded nut that develops outside the fruit, and their classification as a "nut" in the common language is more culinary than botanical.
