Application

Dun pea is one of the field pea cultivar, a variety of pea (Pisum sativum). Field peas is one of the oldest domesticated crops that cultivated for at least 7.000 years in Turkey. Dun peas now cultivated widely with almost 25 million acres’ crops grown worldwide. The major countries that produce dun pea are Russia and China, and then followed by Canada, Australia, United States, and Europe.

The name of dun peas is basically generated from the colour of this pea, which is brown (dun). Dun peas shapes are dimpled and with a greenish-brown colour. This characterization often makes people mistaken it for cowpea. This pea is a cool-season legume crop, based on that many farmers that live in warmer countries usually cultivate this pea under controlled conditions. Field pea is generally used for human consumption or as livestock feeds. Dun peas is the legume that has an excellent nutritional value in it, including Vitamin B, C, and K, folic acid, and fiber. This pea also has a sweet flavor, making this pea great for human consumption.

 

Manufacturing Process

Dun pea or Field pea usually distributed in forms of dry pea. The manufacturing process for dry pea or dry beans are:

Harvesting

The ideal time for harvesting peas varies, depends on the timeliness of harvest, the level of maturity of the pods, and the care in handling. It is important to use clean equipment or clean hands in this process. Peas should be removed from the plants cleanly without tearing them or causing undue damage to the pods or plants.

Cleaning and Sorting

The purpose for this process is to remove any unwanted material. Because peas are quite vulnerable, then a gentle cleaning process is needed. Firstly, coarse dirt in the peas are removed with shake and drum sieve and a blower. Then, peas are fed into the machine through a funnel. In the first part of flotation washer the remaining coarse and heavy dirt particles in green peas are removed. The stream that is formed at the bottom of the washer is strong that only the heavier parts sink. In the second part of the washer light material such as bark, leaves, and pea peels are sorted and will float to the surface of the water. Lastly, using a strong flow of water the soggy and sunken peas are pressed to a vibrating sieve screen. In this last step, any remaining pea peels are loosened and the remaining sand is washed away.

From the cleaning machine, peas are transported to the sorting machine using a conveyor belt or water. Peas then sorted to ensure its uniformity in cleaning, sizing, and prepared to be packed.

Storaging

Peas are usually harvested in large amounts, thus to maintain its quality the beans needed to be stored. Peas are stored in cooling storage, generally refrigeration or field-pack stored in cool places or room cooling. Refrigeration is needed to maintain peas quality and substantially lengthens shelf life by reducing the effects of dehydration and lessen damage that caused by decay-producing organisms.

Packaging

Dry edible beans are packaged in food grade impervious materials to make sure that the integrity of the package allows for minimum subsequent contamination of the product.

 

 

Field pea is usually used for human consumption and livestock feeds. For human consumption, dun peas are great for many dishes, commonly salads, soups, and curry. While for livestock feeds, field pea is mixed with small grain in forage crop mixture. Based on research, dun pea is an excellent protein supplement in swine, cow, feeder calf, dairy, and poultry rations.

Categorization

Dun Pea belongs to the Fabaceae family, making it categorized as beans. However, based on the distribution of its product in dry pea forms, then dun pea could be categorized as pulses.
