850kcal./100g.). In comparison with average values for eight 
cultivated nuts and oil seeds!4, bati-butter is considerably higher 
in fat and calories and lower in protein. On a dry weight basis, 
the values for bati-butter are similar to those for pecans (Carya 
illinoensis) (Wu Lueng and Flores, 1961:68~71). 
Monopteryx is moderately high in fat (23.2g/ 100g) and pro- 
tein (12.6g./100g.). In a fermented state, it is slightly higher in 
protein (17.5g./100g.) and food energy (579 kcal./100g.). In 
comparison with average values for six cultivated pulses, 
Monopteryx is relatively high in fat and low in protein!>. 
The protein values reported here are for crude protein only. 
Although it is a question of much interest, the biological value of 
Monopteryx protein is not currently known. The oil composi- 
tion of both Monopteryx and Erisma seeds is also of interest. 
The oil of Monopteryx angustifolia is not well known, but it has 
all the properties of a good edible oil (Mors and Rizzini 
1966:27). Little is known of the oil of Erisma Japura, but two 
closely related species, FE. calcaratum and E. uncinatum, have 
been shown to have oils of good quality (Pesce 1941:91-94). 
CONSUMPTION PATTERNS 
The consumption of Monopteryx angustifolia and Erisma 
Japura was measured during the 1977 May-June harvest period 
in the village of Yapu. The 24-hour weighed dietary survey 
method was used to record food intakes on a sample of eighteen 
adults. During the survey period, Monopteryx seeds were con- 
sumed freshly prepared as the main part of a meal and as a 
beverage. Erisma seeds were also eaten freshly cooked as the 
principal dish in a meal and, in two instances, as a dip made of 
fermented bati-butter. 
In terms of the total food intake, the two seeds accounted for 
14 Values shown are the average values for the following eight nuts and oil seeds: 
Anacardium occidentale, Bertholletia excelsa, Corylus spp., Helianthus annuus, 
Pinus cembroides, Prunus Amygdalus, Sesamum indicum, and Terminalia Catappa 
(Wu Lueng and Flores, 1961:68 71). 
iS. The values shown are the average values for the following six cultivated pulses: Cicer 
arietinum, Glycine Max, Phaseolus vulgaris, Pisum sativum, Lens spp., and Vicia 
Faba (Wu Lueng and Flores, 1961:66 68).
