attacked by small beetles, and the oil becomes more and more ‘ 
acid, although no change may be noticed in the appearance of 
the kernel and oil extracted. An actual test showed that the 
acidity of the oil was increased from 0.55 to 5.382 when the 
kernels were stored in a cold, dry place for one month. It is 
therefore advisable to extract the oil from fresh nuts. 
Analyses of the kernels of Alewrites moluccana show that the 
principal constituents are oil (consisting largely of fat) and 
protein. The percentage of fiber and ash is very low. This 
is shown by the results recorded in Table 15.

Lumbang oil has a light yellow color, and an agreeable odor and 
taste. It dries in thin films when allowed to stand several days. 
The results of various analyses of lumbang oil quoted by Wilcox 
and Thompson are given in Table 16. Aguilar also analyzed 
various samples of lumbang oil. His results are given in 
Table 17.
