The process of splitting dried peas has evolved over time, from traditional methods using stones and mortars to modern machinery.
Traditional Methods of Splitting Dried Peas
In the past, dried peas were split using traditional methods, such as using stones and mortars. This labor-intensive process involved soaking the dried peas in water, then pounding them with stones to split them open. The split peas were then dried again to remove excess moisture. This method was time-consuming and required a lot of manual labor, but it produced high-quality split peas that were rich in flavor and texture.
The Use of Water-Powered Mills
With the advent of water-powered mills, the process of splitting dried peas became more efficient. Water-powered mills used the power of water to turn stones, which were used to split the dried peas. This method was faster and more efficient than traditional methods, but it still required a lot of manual labor.
Modern Methods of Splitting Dried Peas
Today, the process of splitting dried peas is much more efficient and mechanized. Modern machinery uses a combination of rollers, screens, and air jets to split the dried peas. The process involves several stages, including:
Cleaning and Sorting
The first stage of the process involves cleaning and sorting the dried peas. This is done to remove any debris, stones, or broken peas that may be present. The peas are passed through a series of screens and air jets, which separate the good peas from the bad.
Soaking and Steaming
The next stage involves soaking the dried peas in water, then steaming them to make them soft and pliable. This helps to loosen the skin of the pea, making it easier to split.
Splitting
The peas are then passed through a series of rollers, which split them open. The rollers are designed to apply the right amount of pressure to split the pea, without crushing it. The split peas are then passed through a series of screens, which separate the split peas from the unsplit ones.
Drying
The final stage involves drying the split peas to remove excess moisture. This is done using hot air, which helps to preserve the peas and prevent spoilage.

What is the splitting process of dried peas?
The splitting process of dried peas is a physical transformation that occurs when dried peas are rehydrated. This process involves the breakdown of the pea’s outer skin, allowing the inner starch and protein to absorb water and swell. As a result, the pea splits into two distinct halves, revealing its inner contents.
The splitting process is an essential step in preparing dried peas for consumption. It allows for the rehydration of the peas, making them palatable and easier to digest. The process also helps to break down some of the complex carbohydrates and proteins, making the nutrients more accessible to the body.
Why do dried peas split when rehydrated?
Dried peas split when rehydrated due to the difference in moisture content between the outer skin and the inner starch and protein. When dried peas are exposed to water, the outer skin absorbs moisture at a slower rate than the inner contents. As the inner starch and protein absorb water and swell, the outer skin becomes stretched and eventually breaks, causing the pea to split.
The splitting process is also influenced by the structure of the pea’s cell walls. The cell walls of dried peas are composed of a tough, fibrous material that provides rigidity and support. However, when the peas are rehydrated, the cell walls become weakened, allowing the inner contents to expand and break through the outer skin.
What factors affect the splitting process of dried peas?
Several factors can affect the splitting process of dried peas, including the type of pea, the moisture content of the pea, and the temperature and duration of rehydration. Different types of peas, such as split peas or whole peas, may have varying rates of splitting due to differences in their cell wall structure and composition.
The moisture content of the pea is also an important factor, as peas with higher moisture content may split more easily than those with lower moisture content. Additionally, the temperature and duration of rehydration can influence the rate and extent of splitting, with higher temperatures and longer rehydration times generally resulting in more extensive splitting.
How can the splitting process of dried peas be controlled?
The splitting process of dried peas can be controlled by adjusting the rehydration conditions, such as temperature, time, and water ratio. By optimizing these conditions, it is possible to achieve a desired level of splitting, whether it be minimal or extensive.
For example, to minimize splitting, dried peas can be rehydrated at a lower temperature or for a shorter duration. Conversely, to maximize splitting, the peas can be rehydrated at a higher temperature or for a longer duration. Additionally, the use of additives or preservatives can help to control the splitting process by altering the cell wall structure or moisture content of the peas.
What are the benefits of the splitting process of dried peas?
The splitting process of dried peas has several benefits, including improved digestibility and increased nutritional availability. When dried peas are rehydrated and split, the inner starch and protein become more accessible to the body, making it easier to absorb the nutrients.
Additionally, the splitting process can help to break down some of the complex carbohydrates and proteins, making them more easily digestible. This can be particularly beneficial for individuals with digestive issues or those who have difficulty absorbing nutrients from whole peas.
Are there any drawbacks to the splitting process of dried peas?
While the splitting process of dried peas has several benefits, there are also some drawbacks to consider. One of the main drawbacks is the potential loss of nutrients during the rehydration process. When dried peas are rehydrated, some of the water-soluble nutrients may be lost in the cooking water.
Additionally, the splitting process can also lead to a loss of texture and structure, resulting in a softer or more mushy consistency. This can be a drawback for some recipes or applications where texture is an important consideration.
Can the splitting process of dried peas be used for other legumes?
Yes, the splitting process of dried peas can be applied to other legumes, such as lentils, chickpeas, and beans. While the specific conditions and rates of splitting may vary depending on the type of legume, the underlying principles of rehydration and cell wall breakdown remain the same.
By understanding the splitting process of dried peas, it is possible to apply similar principles to other legumes, optimizing their rehydration and cooking conditions to achieve desired textures and nutritional outcomes.
