B. Banana Peels
Using phytochemical tests in banana peels, it was shown that the peels contain reducing substances such as tannins, mucins, proteins, alkaloids, saponins and flavonnoids. Through fermentation and utilization of Vitamin C, it can produce ethanol and it shows that peels in aqueous solution is acidic as it has the said Vitamin C (Solidum, 2011, June)
Banana peels have surprisingly inventive uses including polishing things. Scientists have now added purification of drinking water contaminated with toxic metals to the list. A study in the American Chemical Society’s journal, Industrial & Engineering Chemistry Research, reports that minced banana peel performs better than an array of other water purification materials and can do so in a sustainable way. Gustavo Castro said, “I chose to work with banana peels because I have heard for a long time that we usually throw out the best part of the fruit and that most of...

- John Soluri’s book, Banana Cultures, examines the production of bananas in the world market, “interactions among diverse and often divided people, not-so-diverse banana plants, and persistent yet unpredictable pathogen’s that formed and reformed tropical landscapes and livelihoods in export banana zones” (Soluri 5).

While the fungal pathogens infected Latin America, the Gros Michel banana invaded the United States.... [tags: Banana, United Fruit Company, Cavendish banana]

- The Role of Consumers in Relation to Cod and Bananas Bananas and Cod, two foods that aren 't paired on many plates, but certainly share similar stories with regards to their harvesting. The fishing industry has recently come under fire again due to the improper methods used to obtain fish in mass. This is due to the consumers demand for an easily recognizable type of fish. Bananas have fallen into a similar issue, in which nearly every store only wants the one type known as, the Cavendish. Other types that vary in size or appearance are exceptionally less valuable from a sellers perspective because of the public demand for the current product....

While trying to find my own personal style, I began to shop at stores similar to Banana Republic and Gap. It soon occurred to me that, although they bear some minor similarities, the difference between Banana Republic and Gap are pronounced.... [tags: Banana, United Fruit Company, Banana republic]

Usually, it is a game of wait three days for them to turn from green to yellow; on the fourth day, have a banana for breakfast when they have finally reached to the point of golden goodness, only to come home from work on the fourth day to find the remaining bananas covered in black spots....

Before thinking about glaze a bisque fired clay body is needed. Then we think about glaze to put on to it. Glaze is made from four specific properties. These Properties are silica, alumina, flux, and a variable. Silica is the glass agent of glaze. Silica can be used as glass by itself but would need to be heated at a temperature that can not be reached by a normal kiln.... [tags: Oxygen, Oxide, Light, Aluminium]

- Bananas are the fruit of a plant of the genus Musa, which are cultivated primarily for food, and secondarily for the production of fibers. It is alleged that there are almost 1000 varieties of bananas in the world, subdivided in 50 groups (Bora, 2007). The most generally known banana is the seedless Cavendish variety, which is the one produced for export markets and pronounced for consuming. The banana is the fruit of an herbaceous plant related to the orchid family and is most commonly found in tropical climate areas which become an exotic product of cold environment zones....
