I conduct this study because I observed that other public places are smelly. Not just in public places but even in our homes. Some kitchens are also smelly because of what we cook and what we eat. If our kitchen utensils are dirty, it can cause disease like diarrhea. That’s why I’ve decided to make an antimicrobial air freshener using organic materials instead of using some chemical. It will not also be antimicrobial but it will also help people because they will breathe fresh and scented air. It will also help people by making a low-cost air freshener. It is very cheaper than other air freshener because high-cost fresheners contains chemicals unlike the air freshener out of organic materials.
It will also by people knowing that Guava [ Psidium Guajava ] and Rosemary [ Rosmarinus Officinalis ] can kill bacterias and fungi that many people can benefit. This will be made by using the two organic materials; Guava [Psidium Guajava] and Rosemary [Rosmarinus Officinalis] . I use Guava [Psidium Guajava] because this fruit has a nice smell and it can also be antimicrobial. This will be result to an antimicrobial,sweet and scented air freshener with the combination of two organic materials; the Guava [Psidium Guajava] and Rosemary [Rosmarinus Officinalis]. This two can kill bacterias and fungis.They are also both fragrant.This would be unlike to other freshener which has strong odors but using organic materials which has sweet smells.
CHAPTER I INTRODUCTION
I.Background of the study
We all know that air fresheners are common in cars and in our homes. When we have air fresheners, we feel comfortable because it gives us a great and fresh scent. Air fresheners are expensive that we cannot afford. It also contains chemicals and has a strong odor. That’s the advantage and disadvantage of air freshener with chemicals.
Air fresheners using organic materials can also give fragant scents like other commercial air freshener but this one does not contain chemicals and it’s scent is sweet not strong like commercial air freshener.That is why I’ve conducted this study not just because of sweets smell but also for people to know that organic materials has an ability to be an air freshener. Guava [Psidium Guajava] is usually 4 to 12 centimetres long, are round or oval depending on the species. The outer skin may be rough, often with a bitter taste, or soft and sweet. Varying between species, the skin can be any thickness, is usually green before maturity, but becomes yellow, maroon, or green when ripe.Guava fruit generally have a pronounced and typical fragrance, similar to lemon rind but less sharp. Guava pulp may be sweet or sour, tasting something between pear and strawberry, off-white to deep pink , with the seeds in the central pulp of variable number and hardness, depending on species.
Rosemary [Rosmarinus Officinalis] an aromatic evergreen shrub that has leaves similar to pine needles. Forms range from upright to trailing; the upright forms can reach 1.5 m tall, rarely 2 m.The leaves are evergreen, 2–4 cm long and 2–5 mm broad, green above, and white below, with dense short woolly hair. The plant flowers in spring and summer in temperate climates but the plants can be in constant bloom in warm climates; flowers are white, pink, purple or deep blue.
Both of this two organic materials has a great fragant scent and both had a possibility to be an alternative air freshener.That’s why I conducted this study.
II.Statement of the Problem
This project tries to research the feasibility of Guava [Psidium Gujava] and Rosemary [Rosmarinus Officinalis] extract as an alternative air freshener that will be comparable to the ones which is sold in markets.
This tries to answer the following:
1) What does Guava [Psidium Guajava ] and Rosemary [Rosmarinus Officinalis] extract can do to be an alternative air freshener ? 2) Is it comparable to the ones which is sold in the market in terms of :
a. Cost ? b. Effectiveness ? c. Odor ?
III.Significance of the study
This project aims to make a product that will be an alternative for local air freshener that contain chemicals and expensive.This study is concentrating in the fragance and aromatic smell of Guava[Psidium Guajava] and Rosemary [Rosmarinus Officinalis]. People will save a lot of money because we will not use chemicals that are expensive.. People will smell fresh and fragrant scent with just a low-cost air freshener.
IV.Definition of Terms
a. Air Freshener- are consumer products used in homes or commercial products used in house.buildings and in even in cars that typically emit fragrance. b. Guava[Psidium Guajava] – The fruit, exuding a strong, sweet, musky odor when ripe, may be round, ovoid, or pear-shaped, 2 to 4 in long, with 4 or 5 protruding floral remnants (sepals) at the apex; and thin, light-yellow skin, frequently blushed with pink. he central pulp, concolorous or slightly darker in tone, is juicy and normally filled with very hard, yellowish seeds, 1/8 in (3 min) long, though some rare types have soft, chewable seeds. c. Rosemary [Rosmarinus Officinalis] – is a woody,perennial herb with fragrant, evergreen, needle-like leaves and white, pink, purple or blue flowers, native to the Mediterranean region. Rosemary has been shown to have antioxidant properties. Antioxidants can neutralize harmful particles in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death. Rosemary oil appears to have antimicrobial properties (killing some bacteria and fungi in test tubes).
V.Scope and Delimitation of the study
This study focused on experimenting the effectiveness of the Guava[Psidium Guajava] and Rosemary [Rosmarinus Officinalis] as an alternative air freshener.This is limited to the use of Guava[Psidium Guajava] and Rosemary [Rosmarinus Officinalis] and the other ingredients if it would be comparable to other Air Freshener.
CHAPTER II REVIEW OF RELATED LITERATURE AND CONCEPTUAL FRAMEWORK
Review of Related Literature
Rosemary (Rosmarinus officinalis) is an evergreen shrub that is grown for its gray green foliage. Often used as a culinary herb, rosemary is also a popular landscaping plant in many parts of the world, and some varieties can grow to six feet in height. Smaller creeping varieties make excellent, dense groundcovers.(S.Elliot,2008)
Rosemary (Rosmarinus officinalis Linn.) is a common household plant grown in many parts of the world. Rosemary is used for flavoring food, a beverage drink, as well as in cosmetics. In folk medicine, rosemary is used as an antispasmodic in renal colic and for dysmenorrhoea, in relieving respiratory disorders and to stimulate growth of hair. Extracts of rosemary relax smooth muscles of trachea and intestine, and have liver protective and anti-tumor activity. ( Ray Sahelian )
Rosmarinus officinalis, one of the most prized culinary herbs, is a common wild plant of Mediterranean hillsides, but will also grow as far north as S. England, where the Romans introduced it originally (although it is commonly said that it had to be reintroduced by the Normans after 1066).(Davidson)
Rosemary (Rosmarinus officinalis) is widely used as a spice when cooking, especially in Mediterranean dishes. It is also used for its fragrance in soaps and other cosmetics. Rosemary has been shown to have antioxidant properties. Antioxidants can neutralize harmful particles in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death. Also in the lab, rosemary oil appears to have antimicrobial properties (killing some bacteria and fungi in test tubes). It isn’t known whether rosemary would have the same effect in humans.(Ehrlich,2011)
Rosemary is one of those wonderful herbs that makes a beautiful ornamental plant as well as a welcome culinary seasoning. Its Latin name, Rosmarinus officinalis, means “dew of the sea” and rosemary is most closely associated with the cooking of the Mediterranean area. However you don’t need perfect sunshine, sea mist or even a never ending summer to successfully grow rosemary. In fact, more rosemary plants suffer from too much attention than from too little.(Iannotti)
Rosemary is an aromatic herb that has a long history of both culinary and medicinal use. Rosemary grows in bushes with wood-like stems and short, pine like needles. Although this herb resembles pine in both appearance and scent, it is actually a member of the mint family. Rosemary is a perineal evergreen that is often grown as an ornamental shrub because of its ability to withstand harsh conditions.(Bethany Moncel)
Rosemary, (Rosemarinus officinalis), is a delicious and beautiful herb. You can find many varieties to fit your need: upright and trailing. Use them interchangeably and even grow multiple varieties as each is distinctly different looking. I use trailing varieties for myherb standards. I braid three stems and use those as the main stem. It gives a more decorative look to my finished standard.(Amy Jeanroy)
Guava fruits vary in size, shape, and colour, even within the principal species, P. guajava. They range from the size of an apple to that of a plum, and may be round or pear shaped, rough or smooth skinned, and greenish-white, yellow, or red in colour. Large, pear-shaped, white ones are considered the best. The fruit has an outer and inner zone, the latter with many small gritty seeds.The taste is acid but sweet, with an unusual aromatic quality partly due to eugenol, an essential oil found also in cloves. Unripe guavas are astringent, but if picked when nearly ripe they are soon ready to eat.(Morton, 1987)
Guava is a tropical fruit, cultivated mainly in the Asian countries. It is quite similar in shape to pear and has a rind that is green in color and changes to yellow when it becomes over-ripe. Inside the rind, which is consumed along with the fruit and not peeled, there is flesh that is either white or pinkish/reddish in color. More often than not, you can find lots of small hard seeds enveloping the soft and sweet pulp of the fruit. Guava is quite rich in Vitamin C, maybe even more than orange, apart from a number of other vitamins and minerals. Browse through the article to know about the health and nutrition benefits of eating guavas. (Lily,2009)
Guavas have more vitamin C than citrus fruit; the edible rind alone has five times the vitamin C of orange.Guavas has a smooth, creamy texture that is akin to an avocado and a flavor that is softly sweet-sour. The seeds add an astrigent quality to the fruit.Guava can also be eaten unripe.(Bill Daley)
A guava is the sweet fruit of the guava tree, which grows in tropical regions of America and Asia. The Guava genus consists of about 100 small trees and shrubs in the family Myrtaceae, with the Psidium species being the most cultivated for food. The guava fruit can be eaten raw or used to flavor drinks, desserts, and sauces. The guava is rich in vitamins A, B, and C, as well as beta carotene. It can be eaten raw, either out-of-hand or seeded and sliced in desserts or salads, although cooking eliminates theguava’s strong smell. (Dellaporta)
There are different varieties of guavas, each with thier own color when ripe. There is the pink guava, the white guava and the peach-fleshed guava.Most guavas when ripe, the skin is cream coloured. The variety is determined by the colour of the pulp. The fruit contains many tiny seeds which are edible. Guavas are a good source of carbohydrates and an excellent source of Vitamin C and fiber. A guava provides two to three times the amount of Vitamin C than orange juice.(Cynthia Nelson)
Guavas are said to be one of the best fruits available and that’s because they are not only a very rich source of vitamin C (a guava contains more of this vitamin than a typical citrus fruit – the rind contains over five times more vitamin C than an orange!), they also contain high amounts of calcium – which is unusual in a fruit.A fresh guava fruit is also a valuable source of vitamin A and B, nicotinic acid, phosphorous, potassium, iron, folate and is high in fibre. Coupled with all these vitamins and minerals (I’m feeling healthy just writing about it!) guavas are also low in fat and calories, with only about 25 calories per fruit.(Greenhouse Girl,2008)
Rosemary is a Mediterranean evergreen shrub which is widely cultivated all over the world for its aromatic and flavorful leaves. Gardeners also use rosemary as a topiary or large ornamental bush, because when allowed to grow, rosemary will get quite large, and produce a profusion of white, light blue, or pale purple flowers. In addition to use in cooking, rosemary is also used in cosmetics and in aromatherapy treatments, as well as in sachets to keep garments smelling sweet and fresh. The herb is available in fresh form in some specialty stores, as well as in in whole dried and powdered forms. (S.E Smith)
Guavas are apple-or pear shaped.The Guava tree can grow up to 12cm long.Guava tastes like a combination of pear and strawberry.The seeds of guavas are edible.The feijoa is the guava’s brother. It is green and more elongated.A specific type of Feijoa is the pineapple guava.Are tropical fruit so do not keep them in the refrigerator. Guava and feijoas can be kept for a few days on a fruit bowl at room temperature.Are a big type of berry.Do not peel guavas because the edible rind contains a lot of vitamin C. Guava is five times more than an organ.Are great thirst quenchers and contain very much vitamin C and much iron.(Sholleybabs)
Guava originated in Mexico and South america but is now grown and consumed in all Asian countries. In Northern Florida, Guava was first cultivated in the early 20 th century. A traditional event called “Guavaween” is celebrated every year on the last Saturday of the month of October, near Ybor city, Tampa, Florida, to celebrate the arrival of Guava. This is one of the largest festivals in Ybor.The major producers of Guava are India, Brazil and Mexico. The best guavas in India are from the city of Allahabad.(Rajan Jolly)
Guavas are super high in Vitamin C and calcium, a good source of Vitamins A, B, potassium, iron, folate and is high in soluble fiber with roughly 25 calories per fruit and helps to lower your cholesterol. These are a super tasting fruit, eat up! (Chef Maven)
Guava is a very popular fruit. It is available throughout the year except during the summer season. Being very hardy, it gives an assured crop even with very little care. Its cost of production is also low because its requirements for fertilizer, irrigation and plant protection are not much. Further its nutritive value is very high. Therefore, it is and ideal fruit for the nutritional security. Guava is also grown as a backyard fruit to great extent. In India, the best quality guavas are produced in Uttar Pradesh, particularly in Allahabad region.(Rathore) Gives fragant scent.
