And, the answer for the the question is :
Explanation:
Due to the cashew shell’s toxicity, consumers can never purchase cashews in their shells. Anacardiaceae, which includes cashews, is the same family as poison ivy. A portion of the cashew plant contains urushiol, an oily toxin that can be lethal if consumed, much like poison ivy and other family members. However, the nuts themselves do not contain the irritants; only the shell oil does. Before being made available for ingestion, cashew seeds must go through a high-temperature roasting procedure to get rid of the potentially dangerous urushiol oil.
When it comes to nuts, many of us enjoy the crunchy texture and delicious flavors they bring to our meals and snacks. However, there is one nut that stands out for a unique reason—the cashew. Unlike most other nuts, cashews are never sold in their shells because the shells contain a poisonous substance. This intriguing fact adds an extra layer of curiosity to this popular nut.
The cashew nut, scientifically known as Anacardium occidentale, is native to northeastern Brazil but is now cultivated in various tropical regions around the world. It is highly regarded for its rich, buttery taste and versatility in both sweet and savory dishes. From cashew butter and cashew milk to cashew-crusted chicken and stir-fried cashew vegetables, this nut adds a delightful touch to a wide range of culinary creations.
So why are cashews never sold in their shells? The answer lies in the structure of the cashew fruit and the presence of a toxic substance called urushiol. The cashew tree produces a pear-shaped fruit called the cashew apple, which has a juicy and tangy pulp. Attached to the bottom of the cashew apple is a kidney-shaped structure known as the cashew nut. It is within this protective shell that the cashew nut, which we commonly consume, is found.
However, the shell of the cashew nut contains a resinous substance called urushiol, which is also found in poison ivy and poison oak. Urushiol is a potent skin irritant and can cause severe allergic reactions in some individuals. It is important to note that roasting or steaming the cashew nut neutralizes the urushiol, making it safe for consumption. This is why cashews are always sold pre-shelled and are readily available in grocery stores and markets.
The process of extracting the cashew nut from its shell involves several steps to ensure safety. Initially, the cashew apple is harvested and the cashew nuts are carefully removed. The shells are then discarded, and the cashew nuts undergo a thorough cleaning process to remove any remaining traces of urushiol. After cleaning, the nuts are typically roasted to enhance their flavor and texture.
While the cashew shell is inedible and can be harmful if handled improperly, it does have some practical uses. The cashew shell contains a substance called cardol, which is utilized in various industries, including the production of paints, varnishes, and even insecticides. Additionally, the cashew shell can be burned to generate heat or used as a fuel source.
cashews are a beloved and versatile nut that brings a delightful taste and texture to many dishes. However, due to the presence of the toxic substance urushiol in their shells, cashews are never sold in their natural protective covering. The careful processing and roasting of cashews ensure that they are safe for consumption and allows us to enjoy their unique flavor and health benefits. So, the next time you reach for a handful of cashews, remember the fascinating reason behind their shell-free availability.
