Avocado an introduction The tree from which the commercial avocado fruit (technically a berry due to the fact it develops from a single ovary and has the seed embedded in the fruit), come from the avocado tree Persea americana Mill which originates from Central America. The avocado is a nutritious fruit high in lipids particularly mono unsaturated which may help lower levels of cholesterol. Avocados are sources of fibre and fairly high levels of protein. It is a good source of Vitamins A, B3, B5, C and E and of the mineral potassium. For a more detailed breakdown of avocados see appendix 1.
Some fruits are sweet as well as sour in taste like orange, as it has almost equal quantities of fructose and acids in it. Fruits like lemons have sour taste; they do not get sweet taste even after ripening due to the presence of excessive amount of acids. Raw bananas have more starch but when the fruit gets ripen, the starch gets converted into fructose. The chemical changes take place inside the fruit during the process of ripening, due to these changes the amount of sugar increases in fruit and it becomes sweet. You will see that even two fruits of same type have different taste like two mangoes or two apples do not have same taste but they are different in taste.
The first and probably most obvious similarity is that they are both fruits, and quite popular fruits at that. Both apples and oranges are tasty and are good sources of vitamin C. The FDA recognizes apples and oranges as a full serving of fruit on the food pyramid. Another similarity between these is that they both grow on trees and are generally a round spherical shape with seeds in the center. They are both often packed in lunches or as snacks because they are easy to handle and can last a long time in a refrigerator before going bad. In contrast, apples are usually red or green, and oranges are surprisingly an orange color.
Limonene, the chief component of orange oil, is widely used as a fragrance and flavoring, as well as a cleaning solvent. Limonene, a naturally occurring hydrocarbon, is a cyclic monoterpene, a class of natural products biosynthesized by the assembly of isoprene units into various structures. Many terpenes are responsible for the odors of plants like eucalyptus, pine, mint, lavender, rose, and others. Organic chemists use terpenes and other natural products as chiral starting materials for complex chemical syntheses or as inspirations for pharmaceuticals. Some natural products are attractive synthetic targets because of interesting or unusual structural features or medicinal applications.
"A Brief History of Sugar." A Brief History. 11 Oct 2008 <http://www.irish- sugar.ie/noframes/nf-pages/nf-hist/nf-hist.htm#productn> Sugar cane is a member of the grass family. The sugar cane has hollow stalks filled with a sweet juice or sap from which sugar can be extracted and can grow to 15 feet tall. It grows best in very warm climates and is ready to harvest after 10 to 20 months.
Some of its characteristics are that it has large green leaves, hollow square stems, and white flowers with purple calyces, which similarly characterizes the sage plant. Recently, this unique plant has become popular among people, especially young adults and adolescents ("Salvia divinorum”, 2008). Since Salvia divinorum is an ethnobotanical plant, it can produce changes in perception, hallucinations, and other psychologically induced changes, therefore engaging people’s attention for its recreational use. The psychoactive component (the element that produces hallucinogenic effects) of Salvia divinorum is Salvinorin A and is currently the most potent naturally occurring hallucinogen in the world (Salvia divinorum, 2006). Salvinorin A induces an intense, short lived hallucinogenic experience qualitatively distinct from that induced by the classical hallucinogens lysergic acid diethylamide, psilocybin, and mescaline (Chavkin, 2004).
The species, often called sweet leaf or sugar leaf, is widely grown for its intensely sweet leaves. A component on the leaf called stevioside is extracted and manufactured into the calorie-free sweeteners you see in stores. Originally Stevia was only available as a "dietary supplement" in the U.S. In 2008 the federal Food and Drug Administration (FDA) granted Generally Recognized as Safe (GRAS) status to rebaudioside A, one of
When you smell caraway oil, you will get a moist wood type smell. When you smell the spearmint oil, you should smell a really strong minty smell. Not only is it really minty, but it has a slight smell of alcohol. In the second part of this lab, you will be using an analytical gas chromatography. The analytical gas chromatography will tell you the retention times of the components in your substance.
He describes the ripe berries as 'glossy purple clot.' The words flow together and are easy to say with, 'glossy' giving an onomatopoeic effect. Heanly uses the metaphor 'clot' which suggest how full and suculent the berries are. Oppositely, Heaney describes the unripe berries as being 'red, green , hard as a knot.' This suggests how small and undeveloped the berries are.
The trees have adventitious roots that bud out from the trunk, and the female trees appear to bear pineapples. The pineapple –like flower is actually made up of a cluster of seeds or keys that range in color from reddish to bright orange to golden. The male trees are called hinano (Hawaiian word), and usually have less leaves, and have a much more fragrant flower. The leaves of the hala tree are long and skinny with thorny edges and midribs along the base. Most of the leaves are green, but there are some hybrid species now with yellow and green striped
