Fresh consumption — scarlet runner bean

Phaseolus coccineus L.

Scarlet runner bean requires mandatory heat treatment before consumption due to high lectin content, including phytohaemagglutinin. The term "fresh" in relation to this crop implies the use of freshly harvested produce, not raw consumption.

In the reference 6 varieties crop Runner bean, where this is mentioned in the description.

The consumption of mature seeds and pods of scarlet runner bean in their raw state is strictly discouraged due to the presence of toxic substances that are neutralized only by exposure to high temperatures. Product safety is ensured exclusively through culinary processing, such as boiling or stewing.

Unlike common bean, scarlet runner bean is more frequently utilized at the stage of technical maturity of young pods before the formation of coarse fibers. It is also permissible to use flowers in salads and to consume the starchy roots of certain varieties; however, the fundamental requirement for mandatory heat preparation remains unchanged for all vegetative and generative parts of the plant.
