| 説明 | The Cashew is a tree in the flowering plant family. Originally spread from Brazil by the Portuguese, the cashew tree today can be found in all regions with a sufficiently warm and humid climate.What appears on the tree to be the fruit of the cashew tree is an oval to pear-shaped accessory fruit or false fruit that develops from the receptacle of the cashew flower. Called the cashew apple, better known in Panama as "marañón", it ripens into a yellow and/or red structure about the size of a plum or pear.The true fruit of the cashew tree is a roughly kidney-shaped or boxing-glove shaped drupe that grows at the end of the pseudofruit. Actually, the drupe develops first on the tree, and then the peduncle expands into the pseudofruit. Within the true fruit is a single seed, the cashew nut. Although a nut in the culinary sense, in the botanical sense the fruit of the cashew is a seed. However, the true fruit is classified as a nut by some botanists. The seed is surrounded by a double shell containing a caustic phenolic resin. Some people are allergic to cashews, but cashews are a less frequent allergen than some other nuts.Cashew fruit contains a potent skin irritant toxin called urushiol (also found in poison-ivy) within the dark green nut shells. This must be removed when the seed inside is processed for consumption; this is done by shelling the nuts, a somewhat hazardous process, and exceedingly painful skin rashes (similar to poison-ivy rashes) among processing workers are common.It is interesting to note that In India, elephant trainers and handlers use this same substance, urushiol, to maintain control over their large sized subjects. |
