This process additionally reduces the diploma of thermal polymerization of the unsaturated alkyl-phenols present in CNSL. These substances are skin allergens, like lacquer and the oils of poison ivy, they usually present a hazard throughout handbook cashew processing. The shell of the cashew nut incorporates oil compounds that can cause contact dermatitis similar to poison ivy, primarily ensuing from the phenolic lipids, anacardic acids, and cardanol. Reactions to cashew and tree nuts also can occur as a consequence of hidden nut ingredients or traces of nuts that will inadvertently be launched throughout meals processing, dealing with, or manufacturing. The drupe first develops on the tree after which the pedicel expands to grow to be the cashew apple. The drupe becomes the true fruit, a single shell-encased seed, which is often thought-about a nut in the culinary sense. The cashew apple, an accessory fruit, is a mild reddish to yellow fruit, the pulp and juice of which might be processed right into a candy, astringent fruit drink or fermented and distilled into liquor. In addition to its nut and fruit, the plant has a number of other makes use of. In: NewCROP, New Crop Resource Online Program, Center for brand new Crops and Plant Products, Purdue University. Soils, Plant Growth and Crop Production.

In Cambodia, the place the plant is often grown as an ornamental fairly than an financial tree, the fruit is a delicacy and is eaten with salt. In the 21st century, cashew cultivation increased in a number of African international locations to satisfy the manufacturing calls for for cashew milk, a plant milk various to dairy milk. One of many targets of the African Cashew Alliance is to advertise Africa's cashew processing capabilities to enhance the profitability of Africa's cashew business. Distillation of this materials provides distilled, technical CNSL containing 78% cardanol and 8% cardol (cardol has yet another hydroxyl group than cardanol). In Cambodia, the bark provides a yellow dye, the timber is used in boat-making, and for home-boards, and the wooden makes glorious charcoal. Timber is used to manufacture furniture, boats, packing crates, and charcoal. The shells yield a black oil used as a preservative and waterproofing agent in varnishes, cement, and as a lubricant or timber seal. It's used in tropical folk drugs and for anti-termite remedy of timber. These embody polyols, which have just lately seen increased demand for his or her biobased origin and key chemical attributes such as high reactivity, range of functionalities, discount in blowing agents, and naturally occurring fireplace retardant properties in the field of rigid polyurethanes, aided by their inherent phenolic construction and bigger number of reactive units per unit mass.

Cashew nutshell liquid (CNSL) or cashew shell oil (CAS registry number 8007-24-7) is a pure resin with a yellowish sheen discovered within the honeycomb construction of the cashew nutshell, and is a byproduct of processing cashew nuts. This pure oil phenol has fascinating chemical structural options that may be modified to create a wide spectrum of biobased monomers. Chemical and Engineering News. Anacardic acid is also used in the chemical trade for the production of cardanol, which is used for resins, coatings, indian cashew and frictional supplies. Ian Duncan. "Growers Manual for Production of Cashew: Nursery and Plantation" (PDF). In 2024, world manufacturing of cashews (in shell) was 4.2 million tonnes, led by Ivory Coast and India, having 41% of the whole when combined (desk). In a reference amount of 100 g (3.5 oz), raw cashews present 553 kilocalories and are wealthy sources (20% or extra of the Daily Value, DV) of a number of dietary minerals, B vitamins, and vitamin K (table). Raw cashew nuts are 5% water, 30% carbohydrates, 44% fat, and 18% protein (table). Cashew sprouts are eaten uncooked or cooked. These allergies are triggered by the proteins present in tree nuts, and cooking usually does not remove or change these proteins.

Some persons are allergic to cashews, however they're a less frequent allergen than different tree nuts or peanuts. Additionally, derivatives from the shell are utilized in products akin to varnishes, lubricant, and paints. Derivatives of the shell are additionally utilized in paints. Almost all cashews produced in Africa between 2000 and 2019 had been exported as uncooked nuts, which are a lot less worthwhile than shelled nuts. The nut shell and uncooked seed are toxic, but the nut is edible once shelled and roasted or steamed. Since it is a powerful irritant, it shouldn't be confused with edible cashew nut oil. The highest quality oil is produced from a single cold pressing. The fruit of the cashew tree is an accessory fruit (sometimes referred to as a pseudocarp or false fruit). Grafting and different trendy tree management technologies enhance and sustain cashew nut yields in commercial orchards. The phrase anacardium was earlier used to consult with Semecarpus anacardium (the marking nut tree) before Carl Linnaeus transferred it to the cashew; each plants are in the same household.
