Advantages And Disadvantages Of Esters

Ethyl ethanoate: Ethyl ethanoate is an ester. Esters are group of organic compounds which have a functional group of –COO-. Esters are liquids that become vapours quickly so they are present in perfumes.

To aid other compounds in penetrating the skin, in combination with its other properties, this seems to be a logical ingredient when it comes to treating acne.

Plastics are also called polymers, are produced by natural products like oil, natural gas or coal.

By canning, freezing, and dehydrating techniques used to process food destroy most of its flavor.” (120). The International Flavors & Fragrances (IFF) company (which is a huge company that manufactures different types of flavors and fragrances through the process of coalescing chemicals. The IFF corporation has branches that vary all over the nation, they are accountable for the different types of flavors of so many foods, drinks, and many personal hygienic products like gum, soap, toothpaste, perfume and body wash.” The basic science behind the scent of your shaving cream is the same as that governing the flavor of your TV dinner.” (122) It is very outrageous that the flavors of the food we consume are created by the mixing of chemicals that the IFF undertakes. Consuming foods that have been chemically fabricated is not a substance our bodies would benefit from. Consumption of chemicals shouldn’t ever be acceptable. Fast food industries have lowered their standards, they prioritize the act of making money in any means possible over the evident facts on why chemicals should not be administered into our

Table 1 shows the different alcohols and acids used for the production of esters. The name of the esters is shown in the last column of this table as well as how the team member identified the odors of the ester produced. Table 2 shows the results for all 5 groups in the class. Most of the esters produced in this laboratory experiment were easily identified as specific fragances such as banana, wintergreen, and menthol. It is shown in the table, that banana was the most identified one followed by tube M and tube A. The rest of the esters, E and B, had more variability in the identification of esters while C was identified as mouthwash, which can be associated to the menthol flavor and odor. Ester in tube B was the hardest to be identified according to Table 2, since it had 4 different associated smells to it. Students identified one of the odors as expo marker which can be due to experimental error in which the ester did not fully react and the solution smelled more like alcohol (ethanol or isopropanol), which are ingredients that most dry-erase markers such as the brand Expo

Instead, these ‘natural’ and ‘organic’ products are being made in factories with hardly anything natural about them. In an article by Joe Lamp’l, host and executive producer of “Growing A Greener World”, states, “Personally, I’d prefer a blemished apple that’s perfectly fine to eat, versus one that has been sprayed with a pesticide just to prevent a little cosmetic damage” (www.growingagreenerworld.com). When growing your own produce it might appear less than perfect. However, if a shopper walks into a grocery store and looks at the produce they all look somewhat perfect. How do you think that happened? How come home-growers produce does not look as perfect? Well when growing your own garden, gardeners are well aware of what pesticides are being used and what harmful additives are not being infused in their produce. They are growing by the work of Mother Nature and not by some machine injecting them with chemicals to speed up the growing process. People go to a grocery with good intentions of buying vegetables and fruits that grew on a farm. Instead they get produce that has been sprayed with pesticides and grown in chemical fertilizers such as DDT (Dichlorodiphenyltrichloroethane). What is so organic about that? When growing their own vegetables gardeners receive produce with the highest vitamin content! Gardeners also do not have to worry about contamination because they monitor over their gardens and are aware of what goes on in them. Also it is fresher because it does not contain any preservatives to make it last longer. Quality over ‘perfection’. You can trust that your food is safe and healthy to eat even with all its blemishes and

In combination with other properties, to help other compounds penetrate the skin, this seems to be a logical component with respect to the treatment of acne.

Esters are derivatives of carboxylic acids. Instead of having the –COOH group, an ester will include an alkoxy substituent which is a hydrocarbon group of some kind attached to the oxygen molecule (-OR) (1, 2). Esters emit fruity smells and are widely used as flavor enhancers or fragrances. Esters are typically the predominant compound in natural fruits and flowers that

primarily as a solvent for chemical processing. It has also been used as a laboratory reagent; in plastic,

Now the advantages and limitations of aspartame with regards to economic factors will be discussed. Since sugar prices are volatile and rising, manufacturers can substitute a small bit or part of its sugar using aspartame. This lowers down the production cost and the capital. Also the price for high-fructose corn-syrup, which is known to be an economical substitute for sugar has also been going up. Because of this, aspartame now acts as a sugar substitute at a cheaper price and it can be made available to the companies at a lower cost (Ajinomoto food ingredients, 2011 para. 2-3). This will then induce more profit for the food companies. Also, since aspartame has a taste stronger to sugar, a small amount of it can already be utilized to match natural sugar taste therefore this can result to lower cost per usage (Ajinomoto, para. 4). With advantages, there also exists several disadvantages. If aspartame will be over consumed in the near future, certain health problems will arise. This

Artificial flavorings are economical and more stable than natural flavors but assumed worse than natural flavors. Often, they are made with Monosodium Glutamate (MSG) a known neurotoxin that influences brain development. Natural flavorings are high-priced to source than artificial flavors, but causes less food sensitivities

Flavors that are there, concocted like a witches’ potion, with ingredients that are almost as hard to pronounce as they are to make. Sadly, the FDA does not require these companies to disclose these ingredients if they are considered safe, or GRAS, “generally recognized as safe” (Schlosser 54). So, the consumer continues to buy, either not realizing or not caring what they are consuming.

Polyethylene is the world’s most widely used plastic. Polyethylene plastic’s principal application was in packaging, from trash bags to milk jugs. It was widely used in the manufacture of everything from trash bags, picnic cutlery and garbage pails, to plastic toys. Polyethylene also replaced glass, wood, and metal in certain applications.

Original flavor with less sugar created for dieter or fitness-conscious people contains higher minerals and vitamins than other two flavors which help drinkers maintain healthy weight, reduce cholesterol and protect body from aging and cancer.

Polymers effect every ones life almost every day allowing us to make many valuable items that can help make our lives easier including plastic, PVC, and shellac there are also natural polymers that we benefit from such as rubber and amber. Polymers are truly a great and very beneficial item to everyone for they are tough, durable, and cheap but they are also recyclable which can be very beneficial to our environment and societal needs. The only negative effect is when it is not properly disposed but this is really the users fault not the actual item its self
