Utilization of Pili Flour As Tea
INTRODUCTION
The Problem: Rationale and Background
This study made use of experimental method of research.
Tea is an aromatic beverage commonly prepared by pouring hot or boiling water over
cured leaves of the tea plant, Camellia sinensis. After water, tea is the most widely consumed
beverage in the world. It has a cooling, slightly bitter, and astringent flavour that many
people enjoy.
Tea
originated
in
China
as
medicinal
drink. It
was
first
introduced
to Portuguese priests and merchants in China during the 16th century. Drinking tea became
popular in Britain during the 17th century. The British introduced it to India, in order to
compete with the Chinese monopoly on the product.
Tea has long been promoted for having a variety of positive health benefits. Recent
studies suggest that green tea may help reduce the risk of cardiovascular disease and some
forms of cancer, promote oral health, reduce blood pressure, help with weight control,
improve antibacterial and antivirasic activity, provide protection from solar ultraviolet
light, and increase bone mineral density. Green tea is also said to have "anti-fibrotic
properties, and neuroprotective power." Additional research is needed to "fully understand its
contributions to human health, and advise its regular consumption in Western diets."
Tea catechins have known anti-inflammatory and neuroprotective properties, help
regulate food intake, and have an affinity for cannabinoid receptors, which may suppress
pain and nausea and provide calming effects.
Consumption of green tea is associated with a lower risk of diseases that cause
functional disability, such as stroke, cognitive impairment, and osteoporosis in the elderly.
Tea contains L-theanine, an amino acid whose consumption is mildly associated with
a calm but alert and focused, relatively productive (alpha wave-dominant) mental state in
humans. This mental state is also common to meditative practice.
The phrase "herbal tea" usually refers to infusions of fruit or herbs made without the
tea plant, such as rosehip tea, chamomile tea, or rooibos tea. Alternative phrases for this
aretisane or herbal infusion, both bearing an implied contrast with "tea" as it is construed
here.

REVIEW OF RELATED LITERATURE
The pilitrees together with its pulp contain sap and resins which exhibit adhesive
properties. But it has not yet been tested experimentally.
In Bicol Region, The Pili Nut is one of the finest gifts of the Philippine tropics to the
world, found its place at the most prestigious specialty food show in the USA. Five (5)
companies producing pili nut snack food variants participated at the Winter Fancy Food
Show (WFFS) in Moscone Center, San Francisco, CA, last January 20-22, 2013. The WFFS
2013 broke records as the biggest specialty food promotional event with 1,300 exhibitors and
and some 20,000 visitors from various countries.
The Pili Tree is a low-maintenance crop. It only needs pruning from time to time,
requiring minimal fertilizers, or even none at all.
The Pili Fruit, green when young and turns into deep purple or black when ready for
harvest, is blanched in hot water for three minutes to easily peel the exocarp and pulp, and
expose the hard, bony shell.
The Pili Kernel is the most important part of the Pili Nut. With its testa stripped off, it
is a slender, yellowish-white core. Only the purest, spotless kernels are used in producing the
traditional Pili Nut recipes even the foreign market has come to love.
The Pili Nut kernel has the flavor of pumpkin seed when raw, and takes on an entirely
different identity when roasted. It is soft yet crisp, with an easy crunch that surprisingly melts
in your mouth, making it a favorite snack food among Filipinos. The same delighted
acceptance is true even in other countries that have already obtained the nut as an imported
staple.
The Pili Tree can be spotted in bushes across tropical Asia and other Pacific islands,
but the ones grown in the Bicol Peninsula, southeastern end of the Philippine island of
Luzon, are acknowledged as the best-tasting. And why ever not; the region is where the best
variables for growing Pili converge.
Home to at least five active volcanoes, one of which is the perfect-coned and worldadmi
Pili Fiber
The Pili nut (Canariumovatum), one of
native to the Philippines and is abundant and wild in the Bicol Region particularly in
Sorsogon, and in parts of Visayas and Mindanao.

Although they are grown as ornamental trees in many areas of the Old World tropics
of Malaysia and the Philippines, only the Philippines produce and process pili nuts
commercially. Production centers are located in the Bicol region, provinces of Sorsogon,
Albay, and Camarines Sur, southern Tagalog, and eastern Visayas. There is no commercial
planting of this crop; fruits are collected from natural stands in the mountains near these
11
provinces. In 1977, the Philippines exported approximately 3.8 t of pili preparation to Guam
and Australia.
Pili is a tropical tree preferring deep, fertile, well-drained soil, warm temperatures,
and well distributed rainfall.
Most pili kernels tend to stick to the shell when fresh, but come off easily after being
dried to 3 to 5% moisture (30C for 27 to 28 h). Shelled nuts, with moisture content of 2.5 to
4.6%, can be stored in the shade for one year without deterioration of quality (Coronel et al.
1983). The most important product from pili is the kernel. When raw, it resembles the flavor
of roasted pumpkin seed, and when roasted, its mild, nutty flavor and tender-crispy texture is
superior to that of the almond. Pili kernel is also used in chocolate, ice cream, and baked
12
goods. The largest buyers of pili nuts are in Hong Kong and Taiwan, the kernel is one of the
major ingredients in one type of the famous Chinese festive desserts known as the "moon
cake". Nutritionally, the kernel is high in calcium, phosphorus, and potassium, and rich in
fats and protein. It yields light yellowish oil, mainly of glycerides of oleic (44.4 to 59.6%)
and palmitic acids (32.6 to 38.2%). The young shoots and the fruit pulp are edible. The
shoots are used in salads, and the pulp is eaten after it is boiled and seasoned. Boiled pili
pulp resembles the sweet potato in texture; it is oily (about 12%) and is considered to have
food value similar to the avocado. Pulp oil can be extracted and used for cooking or as a
substitute for cottonseed oil in the manufacture of soap and edible products. The stony shells
are excellent as fuel or as porous, inert growth medium for orchids and anthurium.
As cited by West and Balce 1923, Pili pulp, 64% of the fruit by weight, contains 73%
moisture.
On dry weight, 8% protein, 33.6% fat, 3.4% crude fiber, 9.2 % ash, 45%
carbohydrate. Pulp oil, greenish yellow in color, is 56.7% oleicglycerides, 13.5% linoleic
glycerides and 29.3% saturated fatty acids. The kernel, which weighs 0.74-5.13 g and which
comprises 4.4-16.6% of the whole fruit by weight, contains: 35.6-51.4% moisture, 11.515.7% protein, 69.2-76.6% fats and 2.59-4.32% carbohydrates. Its mineral and vitamin
contents (per 100 g): 119 mg calcium, 508 mg phosphorus, 2.6 mg iron, 489 mg potassium,
45 IU vitamin A, 0.95 mg thiamine, 0.12 mg riboflavin, 0.4 mg niacin and traces of vitamin
C (Intengan et al. 1968). Kernel oil is composed of oleic glycerides, 58.6% and palmitic
acids, 38.2%; yellow with an agreeable odor and taste, suitable for culinary purposes and
keeps perfectly for as long as 6 months. redMayon Volcano, Bicols land is a fecund mix of

That typhoons regularly pass through the region does not even pose a problem to
BicolanoPili growers, as the Pili Tree is known as a stress tree, that is, the more it is shaken
and beaten by storms, the more it blooms and bears good fruit.
The Philippines is the only country capable of the commercial production and
processing of Pili Nut-based food and by-products, with Bicol supplying 80% of the total
output volume.
A number of articles about Pili were found. Pili Pulp Oil: Potential Value. New
options in large-scale production of pili pulp oil may aid a flagging market Pili
(Canariumovatum Engl.) is the second-most important nut fruit in the Philippines.
Opportunities exist for its development as a major crop export that would compete well on
the global nut market. Pili is a fairly big tree. It can reach a height of about 20 m and can
have a trunk diameter of 40 cm. Leaves are alternate and compound with opposite smooth
leaflets. Its elliptical, oblong, or oval fruit is about 4-7 cm in length and 2.3-3.8 cm in
diameter (Fig. 1).Generally the fruit has three parts: the skin, the pulp, and the nut.
(INFORM- International News on Fats, Oils, and Related Materials.Pham, 2008) Virgin Pili
Nut Oil. The Department of Science and Technology (DOST) in the Bicol Region has
developed a simple method of producing nutritious oil from pili nut (Canariumovatum)
pulp.The process of extracting oil from freshly harvested pili nuts uses minimal heat and
simple cooking and filtration tools, the DOST said in a statement.In Bicol, most of these
14
trees are found in Sorsogon, Camarines Sur and Albay.In 1998, total pili production in the
country was estimated at 9,007 metric tons.Albay is the major pili-producing province which
accounted for 3,549 MT (40 percent), followed by Sorsogon 3,001 MT (33 percent) and
Camarines Sur 1,207 MT (13 percent), reports said. (Flores, 2008. The Philippine Star)
DOST develops Pili Pulp Oil Extraction Technology in Sorsogon. The Sorsogon provincial
office here of the Department of Science and Technology (DOST) has developed a
technology that provides a simple method of producing oil from pilinut pulp. It now serves
as an alternative to the process introduced by the National Institute of Molecular Biology and
Biotechnology (NIMBB) of the University of the Philippines in Los Baos, Laguna which
uses enzymes in extraction and chemicals in refining pili pulp oil. The NIMBB process,
while proven efficient is rather complicated and requires substantial investment and not
suitable with a micro or village-scale pili nut processing venture.The technology introduced
by the DOST provincial office, on the other hand, is composed of simple cooking and
filtration tools that process oil extracts from freshly harvested pilinuts using minimal heat.
(Calleja, 2009.Sorsogon United)
Whats New in Pili Industry. The industry has gone a long way not only in terms of increase
in hectarage but also in the improvement of the quality of the processed products.
Piliplanting is also becoming more commercial. One fellow who is planting more and more
pili trees is Jose Amador of Brgy. Guinlajon, Sorsogon City. He used to have only five
hectares of pili trees some eyars back. Some are planted in between coconuts while some are
planted as monocrop. Traditionally, the Bicolanos have been using pili oil for treating scalp
15
and skin disorders. The oil is also an excellent base ingredient for cosmetics like lip balm,
lipstick, lotion, ointment and spa massage oil. (Sarian, 2011.Agri Plan Talk)
The current status of the pili is equivalent to that of the macadamia some 30 years ago. It has
great potential to develop into a major industry. The immediate concern in pili production is
the difficulty of propagation. The lack of an effective clonal propagation method not only
hampers the collection of superior germplasm but also makes it almost impossible to conduct
feasibility trials of this crop. Few elite pili trees, such as 'Red', 'Albay', and 'Katutubo' were
selected in the Philippines. The National Clonal Germplasm Repository at Hilo, USDA/ARS,
has initiated studies in in vitro and vegetative propagation for the multiplication and longterm preservation of pili. A recently released pili cultivar in Hawaii may further stimulate the
interest in this crop.(Hamilton. University of Hawaii at Manoa)
Most pili kernels tend to stick to the shell when fresh, but come off easily after being dried to
3 to 5% moisture (30 C for 27 to 28 h). Shell nuts, with a moisture content of 2.5 to 4.6%,
can be stored in the shade for one year without deterioration of quality (Coronel et al. 1983).
Related Studies
Lee James study (2009) is to determine which green tea characteristics are related to
consumers liking. In the study, consumers from the U.S. evaluated 6 tea samples from
China, Japan, and South Korea for acceptability. A highly trained panel also evaluated the
green tea samples to provide descriptive sensory attributes that might be related to
acceptability. We found out that U.S. consumers liked the green tea samples with lower
16
flavor intensity and lower bitterness intensity. Consumers acceptability of green tea was
negatively correlated with spinach and animalic flavor and bitterness and astringency of
green teas evaluated using descriptive sensory analysis but the correlation was only
moderate. To learn what green tea flavor characteristics influence consumers liking, future
studies using more green tea samples using different flavor profiles are needed.
Marilyn Skeletons study (2009) and Diane Tayobanas study (2013) is to investigate
production of tea from guyabano leaves. It also deals with the investigation of the quality of
the tea produced and compares it to commercialized tea.
As based on results, the pili pulp and skin can be made into a tea. The tea produced
from combined pili pulp and skin following easy steps, the tea was observed purplish or
brownish violet in color and pure odor. It is environment friendly because the material used
was natural. Compared to commercial tea, this produced product form pili pulp and skin has
a great advantage to the consumers because it is affordable. It also helps to alleviate garbage
in the environment.

SUMMARY, FINDINGS, CONCLUSION AND RECOMMENDATION
This chapter presents the summary, the findings, the conclusion and the recommendation of the
researchers on the study.
SUMMARY:
This study was conducted to test the Utilization and Acceptability of Pili flour as Tea. Three
proportions were made proportions namely: 100% pili flour; 70% Pili flour and 10% Cinnamon;
70% Pili flour, 20% Honey, and 10% Cinnamon. The data were gathered through scorecard by
ten respondents. The quality characteristics of the pili tea that were tested in the study are: Color,

odor, appearance and taste. The Analysis of Variance was used as statistical tool to determine the
significant difference between the different proportions of the Pili Tea
Particularly, the study answered the following questions:
i. What are the qualitative characteristics of the product produced from pili in making
tea in terms of:
A. Color
B. Odor
C. Taste
D. Appearance
2) What is the degree of acceptability of pili in tea making?
3) Is there any significance in the qualitative characteristics of the tea produced from pili
using different proportions?
. FINDINGS:
I.
The proportion that yield the best result is:
1. In terms of Color, the proportion with 70% Pili flour yield the best result followed by the
proportion with 90% Pili flour.
2. In terms of Odor, the proportion with 70% pili flour yield the best result followed by the
90% Pili flour and lastly the proportion with 100% pili flour.
3. In terms of Appearance, the proportion with 70% pili flour yield the best result followed by
the 90% Pili flour and lastly the proportion with 100% pili flour.
4. In terms of Taste, the proportion with 90% pili flour yield the best result followed by both
the proportion with 70% and 100% Pili flour.
5. As for the general acceptability of the three proportions, the proportion with 70% Pili flour
yield the best result followed by both the proportion with 90% and 100% Pili flour.
II.
The study found the following to be significant:
A. The level of acceptability according to the following qualitative characteristics are:
1. In terms of Color, all of the three proportions had a very good remark
2. In terms of Odor, all three proportions had a very good remark.
3. In terms of Taste, both proportion with 90% Pili flour and 70% Pili flour had a very
good remark while 100% proportion had a good remark.
34
4. In terms of Apperance, all of the three proportion had a very good remark
CONCLUSIONS:
Based from the results of the study, the following conclusions are drawn.
1. The difference in means is not significant especially in terms of color, odor, texture, and
appearance. This means that the different treatments are as good as each other.
RECOMMENDATIONS:
Based from the results and conclusion of the study, the researchers recommend the use of
pili flour in making tea.
For further research, the following are recommended:
1. That similar research shall be adopted but with combination of other variables.
2. Similar studies be conducted but higher concentration of pili flour should be used.
