Extraction Of Oil From Watermelon Seed
Chapter One
Preface
The comestible fruit of watermelon( Citrullus lanatus) belongs to the family Cubitaceae. The fruit contains numerous obovate, smooth compressed seeds thickened at the periphery and of a black or unheroic white colour. Watermelon plays a veritably important part in Africa as it’s used to quench thirst when there’s deficit of water. The seed of watermelon( Citrullus lanatus) can be bruised and rubbed up with water to form an conflation, which can be used to cure catarrhal infections, diseases of the intestine, urinary passage and fever. It’s also being used as worm expeller, in recent times it has been used to expel tape recording worm( Abiodun and Adeleke, 2010). In Nigeria, the watermelon seed is frequently discarded after the juicy part has been eaten. The seed constitutes a public nuisance because the merchandisers of watermelon don’t dispose of these in a aseptic manner. thus, this design work when successfully completed will convert waste into wealth. From former studies on watermelon seed oil painting, it’s light piercing and rich in essential adipose acids( Abiodun and Adeleke, 2010). As a result of significance of drying ways, this exploration was designed to observe the effect of two drying styles on the physico- chemical parcels of the seed oil painting and also to determine its edibility and effectiveness in cleaner timber. In Africa, Watermelon seeds have been prized for the largely nutritional oil painting that they contain. Traditionally, the seeds are removed from the rind and also allowed to dry outdoors in the sun. Once dried, the seeds are also pressed to prize the salutary oil painting. Natural Sourcing provides the most superior watermelon seed oil painting available. It’s precisely reused and packaged to maintain the chastity, newness and salutary parcels of this exceptional watermelon seed oil painting.
The adipose acid profile of comestible canvases plays an important part in their stability and nutritive value. Monounsaturated( 181) and polyunsaturated( 182) adipose acids have been set up to be effective reserves for saturates as part of cholesterol- lowering diets( Mattson and Grundy, 1985). still, it’s also known that the canvases with substantial quantities of unsaturation, particularly 182 adipose acids, are susceptible to oxidation and may produce products that contribute to arteriosclerosis and carcinogenesis. Some studies with experimental creatures indicate that inordinate quantities of linoleic acid promote carcinogenesis
Kubow, 1990). Watermelon seed oil painting, rich in linoleic acid(
), is used for frying and cooking in some African and Middle Eastern American countries retaining to its unique flavour( Akoh and Nwosu, 1992). important exploration has been published on the oxidative stability of some vegetable or fruit canvases , but a little has been reported on the stability of watermelon seed oil painting. The revision of watermelon seed oil painting adipose acid composition by objectification of oleic acid( 181) has been explored( Charment etal., 1997). The modified watermelon seed oil painting was produced with the better balance of monounsaturated( 181) and essential Adipose acids( 182), and also bettered the seed oil painting oxidative stability and nutritive value( Charment etal., 1998). The watermelon family Cucurbitaceae is the most popular fruit in Serbia, with a traditional name ″ lubenica ″. Unfortunately, there’s no information of domestic operation or medicinal values of this seed oil painting for cuisine and or frying as useful source of oil painting with good nutritive value. therefore, watermelon seed oil painting composition( physical and chemical) shall be estimated in this present study, which has not been preliminarily delved . The data generated in the work may help in the unborn selection of watermelon seed oil painting for use in mortal diet.
The light texture, moisturizing capabilities and stable shelf life of watermelon seed oil painting makes it a largely suitable emollient in natural baby care phrasings and light body mixes. Unlike mineral oil painting that’s a common component in marketable skin systems, watermelon seed oil painting doesn’t clog pores or help the body from natural elimination of poisons through the skin. The rich composition of essential adipose acid contained in watermelon seed oil painting nourishes and restores pliantness to the skin( Akoh and Nwosu, 1992). It may be recommended for use in skin care phrasings for all skin types including dry, unctuous and growing skin. Watermelon seed oil painting may also be a perfect choice for addition in hair care phrasings as it’s non slithery yet largely moisturizing. Grinding the dry seed, unloading or rolling of the seeds to carry out birth of oil painting, this is also subordinated to mechanical processing to liberate the oil painting or the use of chemical detergent.
Points And Objects
The points and objects of the design are;
Ø Determine the oil painting content in the watermelon seed using soxhlet extractor.
Ø Determine the physico- chemical characteristic parcels of the uprooted oil painting.
Ø Use of normal hexane and petroleum ether as an extractive detergent.
Ø Effect of two drying styles on the physico- chemical parcels of the watermelon seed oil painting.
Ø Determine its edibility and effectiveness in cleaner timber.
Ø Determine the proximate analysis of the seed.
Scopes
Ø Collection of the watermelon seeds from road side peddlers .
Ø Drying and junking from the shell.
Ø Drying proper( oven drying and sun drying).
Ø drawing of the seed.
Ø importing of the watermelon seed.
Ø Grinding of the seed.
Ø Proximate analysis of the seed.
Ø Sieving to gain flyspeck sizes of varying confines.
Ø birth using soxhlet system, petroleum ether and hexane as detergent.
Ø Characterization of the oil painting( physical and chemical).
Problem Statement
In Nigeria, the watermelon seed is frequently discarded after the juicy part has been eaten. The seed constitutes a public nuisance because the merchandisers of watermelon don’t dispose of these in a aseptic way. thus, this design work when completed will succ
