The results of the Chiu-Square show that although more people would
rather purchase the commercial drink, the difference is statistically
insignificant.

ABSTRACT
The study involved a proximate analysis of the fruit’s nutritive content.
The values obtained were then compared with common food sources.
The edibled portion of the talisai fruit frut are 57% and 5% for its
pericarp and nuts respectively. The fruit’s pericarp is composed of 90.35%
moisture, 0.20% crude fiber, 0.06% ash, 1.05% protein, 4.31% fat and
4.03% carbohydrate. For the nut, its composition is as follows: 34.100%
moisture, 2.38% crude fiber, 3.34% ash, 2.11% protein, 35.30 fat and
22.77% carbohydrate.
The nut has a higher nutritive value compared to the pericarp and is
therefore a better food source.

paper pulp

ABSTRACT
Soda pulps obtained from the leaves and trunk of Carica papaya
(papaya) were subjected to a quantitative chemical analysis. Results were
then compared with standards to determine whether such pulps are suitable
for papermaking.
Results are as follows: leaves: 7.26% ash, 21.65% pentosan, 58.82%
alpha-cellulose, 18.63% solubility in 1% NaOH; Trunk: 35.8% ash, 25.83%
pentosan, 68.72% alpha-cellulose, 24.4% solubility in 1% NaOH. Standards
are: less than .15% ash, 2-20% pentosan, more than 85% alpha-cellulose,
less than 15% solubility in 1% NaOH.
The pulps from the leaves and trunks of carica papaya are not good
paper pulps due to the high ash and pentosan content, low- cellulose content,
and high solubility in 1% NaOH.
