CASHEW-NUT OIL 



The roasted kernels are often used to make a very savory 

 nut candy, and also, according to Richmond and Rosario,* for 

 the adulteration of chocolate. They say that the expressed ker- 

 nels yield a sweet, yellowish oil. 



Lewkowitsch f states that the yield of oil from the kernels is 

 47.2 per cent and that the oil has the following constants: 



Saponification value 195 



Iodine value 84 



Refractive index (20°) 1.4702 



Watt t says that : 



* * * Two oils are obtainable from this plant: (1) a light-yellow 

 from the pressed kernels, of which the finest quality is equal to almond oil; 

 and (2) "Cardole," obtained from the shell of the nut — an acrid and 

 powerful fluid efficacious for preserving carved wood, books, etc., against 

 white ants. * * * 



Watt also mentions that the bark yields a gum which is ob- 

 noxious to insects. 



Anacardium occidentale is a small tree with a trunk which is 

 usually small and crooked. It has a large, yellow, pear-shaped 

 fruit, with a kidney-shaped seed attached to one end. Both the 

 fruit and seed are edible, the fruit raw and the kernels raw or 

 roasted. 



This species, introduced at an early date from America, is 

 widely distributed in the Philippines. It is cultivated in towns 

 and on farms, and runs wild in old clearings.
