Melon seed oil

Rubber Seed Oil Rubber seed oil (RSO), which has a high C18 3, n-3 content (6), has a lower alcoholysis rate than linseed oil, but a higher alcoholysis rate than soybean oil and melon seed oil (165). Studies on the epoxidation of RSO by peroxyacetic acid generated in situ have shown that increase in the process temperature increases the rate of epoxide formation (166). The optimum alcoholysis temperature for RSO is 245 2°C. 

Melon, Cucumis melo, is a member of the Cucurbitaceae family and grows best in tropical regions. The pulp of the fruit has pleasant flavor and taste, and the seeds are generally treated as waste however, medicinal effects have been reported for the seeds (24, 25). Hexane-extracted seed oil of Cucumis melo hybrid AF-522 was determined to contain 64 g of linoleic acid per 100 g of total fatty acids (Table 4) (24). Significant amounts of oleic, palmitic, and stearic acids were also detected in the melon seed oil. The specific gravity (28°C), refractive index (28°C), and iodine value of the seed oil were 0.9000, 1.4820, and 112, respectively, under the experimental conditions (24). Earlier in 1986, Lazos (25) extracted the oil from Cucumis melo seeds and examined its physicochemical properties (25). Linoleic acid was the primary fatty acid and accounted for 64.6% of the total fat (w/w), along with 20.1% oleic acid, and 14.7% total saturated fatty acids (Table 4). Iodine value and refractive index (40°) of the seed oil were 124.5 and 1.4662, respectively. 

The Langmuir equation has been used to describe adsorption of p carotene from solution onto activated bleaching clays (8) and free fatty acid from isooctane solution by acid-washed rice hull ash (9). Likewise, isotherm analysis of the commercial bleaching of rubber and melon seed oil by Fullers earth, activated carbon, and Fullers earth/activated carbon mixture (10) followed Langmuir behavior at 55°C and 80°C, suggesting the possibility of monolayer adsorption with little competition. This behavior was not observed at 30°C where the isotherm no longer applies, because of desorption. The amount of adsorbent was kept constant while varying... 

Melon Citrullus colocythis and C. vulgaris). This seed oil has been examined in terms of its fatty acids and phospholipids by Akoh and Nwosu (139). The major fatty acids in the total lipids are palmitic (11% and 12%), stearic (7% and 11%), oleic (10% and 14%), and linoleic acid (71% and 63%) for two samples. 

Linoleic acid (18 2n-6) is an essential fatty acid that must be obtained through diets. In this section, fruit, spice, and herb seed oils rich in linoleic acids are summarized. These seed oils include watermelon, melon Cucumis melo and Colocynthis citrullus), goldenberry, grape, rose fruit, paprika, red pepper, onion, black cumin, and Onagraceae seed oils. Several seed oils may be listed in other sections if they contain significant level of a special fatty acid. For example, pumpkin seed oils rich in both oleic acid and linoleic acid, are listed under the section named, Edible seed oils rich in oleic acid (18 ln-9). ... 

Watermelon, Melon (Cucumis melo), Melon Colocynthis citnjilus L.), Goldenberry, Grape, Rose, and Paprika stand for Watermelon, Melon (Cucumis melo), Melon (Colocynthis citmllus L.), goldenberry, grape, rose, and paprika seed oil, respectively. Numbers correspond to the references cited, nd stands for not detected. 

Pumpkin, Curcubita sp., is a member of the gourd family, Curcubitaceae, that also includes melons, cucumbers, squash, and gac. In 2003, the United States production of pumpkins was approximately 335,000 MT (http //usda.mannlib.comell.edu/ reports/nassr/fruit/pvg-bban/vgan0104.txt). In some mid-eastem African countries, dried pumpkin seeds have been used to treat tapeworm when eaten on an empty stomach (53). Also, for many years in Europe, pumpkin seeds have been used as a remedy for micturition. Pumpkin seed oil has also shown possible beneficial affects in retarding the progression of hypertension (54), potential anti-inflammatory activity in arthritis (55), and may be effective in reducing the risk of bladder-stone disease (56). 

There are several minor oilseeds that an important because of their special characteristics, properties, nutritional and health benefits. These include high-y-linolenic oils (evening primrose, borage or starflower and blackcurrant), virgin olive oil (Chapter 9), and the seed oils from sesame, rice bran, pumpkin, hemp and melon. This chapter deals with three minor vegetable oils, namely sesame seed oil, rice bran oil, and flaxseed (linseed and linola) oil. 

A large variety of seed oils have been used in the preparation of polyester. Rubber seed oil and karinotta oil were used in the preparation of air dried and oil-modified polyester resins. The resins were also prepared by the reaction of orange seed oiVJatropha curcas seed oil with glycerol and phthalic anhydride. Melon seed and rubber seed oils have also been used in preparation of polyester resins. The study shows rubber seed oil may be substituted for linseed and soybean oils in the preparation of both long and medium oil length polyester resins. It has also been found that melon seed...

Fullbrook (1983) used proteolytic enzymes and carbohydrases to enhance oil recovery of finely milled slurries of melon seeds, soybeans and rapeseeds. Better yields of oil recoveries were obtained when hexane was added to the aqueous slurries, however, the amounts were significantly lower than the Soxhlet extractable oils in the samples. 

Research concerning the structure, composition, and usefulness of cucurbit seeds (gourds, melons, squash, etc.) is reviewed. Cytological features are typical of those for oilseeds. Composition-ally, decorticated seeds contain by weight 50% oil and 35% protein. The oil is unsaturated and edible however, certain species contain conju-ated trienoic fatty acids (drying oils). 

Preparation Half the melon in a zigzag manner, separate the halves, remove the seeds from the melon halves, and use a melon bailer to scoop out even-sized balls. Place the half of the melon balls, radishes, bell pepper, and pears in a large salad bowl, and marinade the salad with lemon juice. Then store the melon halves and the salad in the fridge for at least half an hour. Meanwhile, mix the seasoning oil of your choice with sour cream and curd, and season with salt and pepper. Stir the mixture into the salad carefully and 11 the salad into the melon halves. Garnish them with herbs and some of the extra melon balls.
