ACKNOWLEDGMENT
We would like to acknowledge the following people and institutions who haveprovided
us with the support needed to accomplish this research:
No words of thanks can sum up the gratitude that owes to our participants, the 10
chosen residents of Brgy. Pajo, Daanbantayan, Cebu. Without their support, our study would
not have been this accurate and flawless.
We thank profusely the farmers of Sitio Tagasa, Bitoon, Daanbantayan, Cebu for
allowing us to collect okra from their area. We admire their hard work in yielding healthy okra
pods.
It is a genuine pleasure to express our deepest sense of thanks and gratitude to our
Practical Research and Inquiries, Investigation, and Immersion adviser, Mr. Rodulfo A.
Capangpangan Jr. who has the attitude and the substance of a genius: he continually and
convincingly conveyed a spirit of adventure regarding research, and excitement regarding
teaching. Without his guidance and persistent help, this science investigatory project would
not have been possible.
Our sincere appreciation also goes to our adviser, Ms. Desiree M. Bonocan for the
continuous support of our study and research, for her patience, motivation, enthusiasm,
insightful comments, and immense knowledge. Her dedication and keen interest above all her
iv
overwhelming attitude to help her students had been solely and mainly responsible for
completing our work. Her timely advice, meticulous scrutiny, and scientific approach have
helped us to a very great extent to accomplish this task.
We can barely express our gratefulness to our parents for their unwavering support of
our academic endeavors. This is also extended to our friends, for their encouragement
throughout the process of accomplishing this study.
We are highly obliged to the divine grace of Almighty God, for His blessings, and for

ABSTRACT
This research aims to investigate the potential of okra as a preservative of cooked rice.
Okra contains 6.0 – 7.5 acid, which can slow the spoilage of cooked rice and inhibits the growth
of most bacteria. It contains water-soluble polysaccharides that are used to prevent food
decomposition and fermentation. This study seeks to dissect the underlying scientific concept
featured in other potential elements of preserved okra mixture. Lastly, the researchers aimed
to determine the effectiveness of the polysaccharides of okra in preventing cooked rice from
spoiling quickly.
The study uses quantitative content analysis in analyzing the fundamental elements of
okra and in dissecting the underlying concept of the preserved okra mixture. True experimental
research posttest only controls group design and the Bonferroni test is used in the research in
the treatment of data.
Upon careful investigation of the data gathered, it was found out that the water-soluble
polysaccharides of okra can prevent cooked rice from spoiling quickly. This experiment
demonstrates that it can assist many families in Brgy. Pajo, municipality of Daanbantayan,
Cebu, particularly the head of the family, in determining how to eliminate rice spoilage, which
leads to rice expenditure. It may also reduce food waste and contribute to the country's
progressive economy.
Key words: acidity, bacteria, cooked rice, .prevention, polysaccharide, spoilage
