Madman Muntz (1914–1987) sold and promoted cars and consumer electronics in the United States from the 1930s until his death in 1987. He was a pioneer in television commercials with his oddball "Madman" persona—an alter ego who generated publicity with his unusual costumes, his stunts, and his outrageous claims. Muntz also pioneered car stereos by creating the Muntz Stereo-Pak, better known as the 4-track cartridge, a predecessor to the 8-track cartridge developed by Lear Industries. He invented the practice that came to be known as Muntzing (which involved simplifying otherwise complicated electronic devices), produced and marketed the first black-and-white television receivers to sell for less than $100, and created one of the earliest functional widescreen projection TVs. He also coined the abbreviation "TV" for television. Although he dropped out of high school, Muntz made fortunes by selling automobiles, TV receivers, and car stereos and tapes. A 1968 Los Angeles Times article noted that in one year he sold $72 million worth of cars, that five years later he sold $55 million worth of TV receivers, and that in 1967 he sold $30 million worth of car stereos and

Guava From Wikipedia, the free encyclopedia Jump to: navigation, search Guava

Apple guava (Psidium guajava)

Scientific classification Kingdom Plantae : Division: Magnolioph yta Class:

Magnoliopsi da

Subclass Rosidae : Order:

Myrtales

Family:

Myrtaceae

Subfamil Myrtoideae y: Genus:

Psidium L.

Species

About 100, see text. Guava is a genus of about 100 species of tropical shrubs and small trees in the myrtle family Myrtaceae. Native to Mexico and Central America, northern South America and parts of the Caribbean, it is now cultivated throughout the tropics. Numerous references in medical research identify guava as Psidium guajava. They are typical Myrtoideae, with tough dark leaves that are opposite, simple, elliptic to ovate and 5-15 cm long. The flowers are white, with five petals and numerous stamens. In several tropical regions, including Hawaii, some species (namely Cattley guava a.k.a. strawberry guava, P. littorale) have become invasive weed shrubs. On the other hand, several species have become very rare and at least one (Jamaican guava, P. dumetorum), is already extinct. The genera Accara and Feijoa (= Acca, pineapple guava) were formerly included.

[edit] Etymology The name appears to derive from Arawak via Spanish, guayaba. In Hindi as well as Urdu, guava are called amrood, in Marathi peru, in Sri Lanka pera, in Telugu jaama (జమ), in Bengali peyara (েপয়ারা) and in Tagalog bayabas, probably a local rendition of guayaba.

[edit] Cultivation Guavas are cultivated in many tropical and subtropical countries for their edible fruit. Several species are grown commercially; apple guava (P. guajava) and its cultivars are those most commonly traded internationally. Mature trees of most species are fairly cold-hardy and can survive as low as 5°C for short periods of time, but younger plants will not survive. They are known to survive in Northern Pakistan where they can get down to 5°C or lower during the night. Guavas are also of interest to

home growers in temperate areas, being one of the very few tropical fruits that can be grown to fruiting size in pots indoors.

[edit] Culinary uses and peel nutrients The guava fruit is edible, round to pear-shaped, from 3-10 cm in diameter (up to 12 cm in some selected cultivars). It has a thin delicate rind, pale green to yellow at maturity in some species, pink to red in others, a creamy white or orange-salmon flesh with many small hard seeds, and a strong, characteristic aroma that is hard to describe but generally reminiscent of refreshing fruit like apples, passionfruit or strawberries, with an inoffensive acidity and a fragrance reminiscent of rose petals. The whole fruit is edible, from seeds to rind, but many people choose to cut out the middle which contains hard seeds embedded in the surrounding pulp. The pulp is sweetest in the center, with the outer layer being sour and gritty like young pears, while the peel is sour in taste but richest in phytochemicals; it is usually discarded but can be eaten as an enriched source of polyphenols and essential nutrients, especially an exceptional content of dietary fiber.[1] The fruit is also often prepared as a dessert. In Asia, fresh raw guava is often dipped in preserved prune powder or salt. Boiled guava is also extensively used to make candies, preserves, jellies, jams, marmalades (goiabada), juices and aguas frescas. In Asia, a tea is made from guava fruits and leaves. Guava juice is very popular in Mexico, Egypt and South Africa. Red guavas can be used as the base of salted products such as sauces, constituting a substitute for tomatoes, especially for those sensitive to the latter's acidity. Guava wood is used for meat smoking in Hawaii and competition barbecue. Psidium species are used as food plants by the caterpillars of some Lepidoptera, mainly moths like the Ello Sphinx (Erinnyis ello), Eupseudosoma aberrans, Snowy Eupseudosoma (E. involutum)and Hypercompe icasia. Mites like Pronematus pruni and Tydeus munsteri are known to parasitize Apple Guava (P. guabaya) and perhaps other species. The bacterium Erwinia psidii causes rot diseases of the Apple Guava. The fruit are also relished by many mammals and birds. The spread of introduced guavas owes much to this fact, as animals will eat the fruit and disperse the seeds in their droppings.

[edit] Nutrients and dietary antioxidant value Guavas are often considered superfruits, being rich in vitamins A and C, omega-3 and -6 polyunsaturated fatty acids (mainly in the seeds which must be chewed to obtain the omega fats) and especially high levels of dietary fiber. A single Guava contains over four times the amount of vitamin C as a single orange (228mg per 100g serving), and also has good levels of the dietary minerals, potassium, magnesium, and an otherwise broad, low-calorie profile of essential nutrients. However, nutritional value is greatly dependent on type, the strawberry guava notably contains only 37mg of vitamin C per 100g serving, practically a tenth of the vitamin C found in more common varieties.[2] Guavas contain both major classes of antioxidant pigments -- carotenoids and polyphenols, giving them relatively high dietary antioxidant value among plant foods.[3][4][5] As pigments provide plant food their colors, guavas that are red, yellow or orange in color have more potential value as antioxidants sources than unpigmented species.[6]

[edit] Medical research

Since the 1950s, guava, particularly its leaves, has been a subject for diverse research in chemical identity of its constituents, pharmacological properties and history in folk medicine.[7] For example, from preliminary medical research in laboratory models, extracts from guava leaves or bark are implicated in therapeutic mechanisms against cancer, bacterial infections, inflammation and pain.[8][9][10] Essential oils from guava leaves have shown strong anti-cancer activity in vitro.[11]

[edit] Folk medicine applications Guava leaves are used as a remedy for diarrhea[12] and for their supposed antimicrobial properties. Guava leaves or bark have been used traditionally to treat diabetes.[13][14]
