At the processing plant, beans are sorted out for size, washed and their ends are snipped off mechanically. They are then cut transversely or longitudinal and blanched.
Some beans are frozen individually and placed in plastic pouches alone or as a component of mixed vegetables or they may be first packaged and then frozen in a blast freezer. Some beans are canned in brine and processed.
Canning and freezing are the two most commonly used commercial methods of processing the beans. Other products such as purees for the beans are marketed as baby foods or specialty applications.
