Side Effects Of Potassium Sorbates

This experiment was started with a clear solution of sodium benzoate and HCl was added to it, ultimately producing benzoic acid. First, .3395 g of sodium benzoate was weighed, then it was dissolved in water, causing it to disassociate into ions. Next, 3M of HCl were added drop wise to the solution until it reached a pH of 2, thus introducing the hydronium ion. This addition caused a white, solid benzoic acid to precipitate out of the solution. A vacuum filtration system was used to separate the solid from the liquid. What was once

For this experiment, an organometallic reagent was used for the synthesis and isolation of benzoic acid. The Grignard reaction is the addition reaction of an organometallic reagent, which in this case was an organomagnesium reagent. An organometallic reagent is a carbon bonded to a metal. This reagent was combined with an electrophile, a carbonyl compound such as a ketone or aldehyde. Carbons are electrophilic when bound to a nonmetal thus the atoms are more electronegative than the carbon and metals are less electronegative than carbon.

The very first artificial dye was created by accident in 1856 by William Perkin9. Perkin’s dye chemistry set the stage for pharmaceuticals, plastics, etc. These products were not intended to be used for consumption, yet we eat them daily and use them in numerous other products, such as supplements, medicines, mouthwash, shampoo, and hand sanitizers (Gavigan, 2013). Gavigan’s general claim in the article is that petroleum based dyes are not safe. He goes on to also claim that “FD&C Red No. 40 may accelerate the appearance of immune-system tumors in mice; causes hypersensitivity (allergy – like) reactions and hyperactivity in children”. The article also gives a breakdown of the other 7 food dyes and their health risks.

Benzoic acid is also commonly known as Phenyl Carboxylic Acid, Dracylic Acid, Benzenecarboxylic Acid, Benzoate, and Retardex to name only a few. It can be identified by it's chemical formula C7H6O2 or by its molecular formula C6-H5-C-O2-H. Benzoic acid has a molecular weight of approximately 122.12 g/mol. At room temperature, it appears to be an opaque solid, generally a white power or crystal. At normal STP benzoic acid is a stable compound so it will not react; however, it can decompose under certain conditions, which can cause toxic carbon oxides, also it reacts with oxidizers to product vigorous exothermic reactions. When benzoic acid is exposed to a heat source or to a flame; there is a small

Through extensive research, scientists have concluded that artificial sweeteners are carcinogenic; a cancer causing agent. Scientific research has revealed that cyclamate in combination with saccharin, the two main ingredients in artificial sweeteners, caused bladder cancer in laboratory rats. Though test where not done on humans scientist believe that the long-term effect of using artificial sweeteners would lead to the same complications in humans. Amino acids are biologically important organic compounds composed of amine and carboxylic acid functional groups. The human body needs amino acids to thrive. It is documented that ingestion of high amounts of artificial amino acids found in artificial sweeteners can have adverse effects on the human body such as cancer.

With this increase in the productivity of farmers, came a proliferation of food processing industries and fast food restaurants. These food processing industries and restaurants capitalized on the abundant, overly cheap commodity crops to their advantage; to make profit, and to the disadvantage of poor Americans. During processing of these commodity crops, the natural nutrients that give these foods their natural flavors are destroyed. To replace these, food additives and flavorings are added to restore their taste and prolong their shelf life. Often these chemicals contain some harmful elements that affect the way our bodies use food. These highly processed foods, dense in calories,

According to the author, the scientist of the field believe that stories about problems created by Carrageenan are just anecdotes. Although, studies on lab animals and human cells have suggested that it can create gastrointestinal inflammation but, many researchers and physicians believes that the additive may not create the same impact on people. However, Joanne Tobacman (UIC physician and professor)

A pre-weighed (0.315g) mixture of Carboxylic acid, a phenol, and neutral substance was placed into a reaction tube (tube 1). tert-Butyl methyl ether (2ml) was added to the tube and the solid mixture was dissolved. Next, 1 ml of saturated NaHCO3 solution was added to the tube and the contents were mixed separating the contents into three layers. Once this was completed

Sodium Benzoate is a common food preservative used in food products such as jams and jellies, soft drinks, pickles, condiments etc and in tinned products in the market. This experiment aimed to determine whether benzoic acid is formed from it’s superior soluble form sodium benzoate in stomach acid, which is simulated by HCl (pH=2). It has been seen that at a low optimum pH, i.e. in the presence of sufficient hydrochloric acid, sufficient benzoic acid is yielded. The percentage yield is determined from the calculations of the theoretical (stoichiometric) calculations and the actual

Food additives can be found in lots of food that most people consume. Although food additives can make our food look delicious and even taste better, they contain many dangerous chemicals that may affect our health. Food additives can cause health problems in a person’s lifestyle. Many people do not realize the harm it can cause to their bodies. There are many problems, but also solutions to this situation. The solutions to this situation are: stay away from all kinds of additives, do not eat food that are preservatives, read the labels carefully, and find the FDA signs.

Sodium benzoate is a food preservative that is used in acidic foods like hot sauce and salad dressings.

1. However, while these products might look appealing and tasty, they contain a wealth of hidden heath hazards which are not only dangerous if eaten in large quantities but are a major cause of obesity, especially in children (White, Janice).

In this experiment, methyl benzoate was synthesized from benzoic acid and methanol with acid catalyze using Fisher Esterification. First benzoic acid and methanol were mixed in 100 mL round bottom flask. We cooled the mixture in ice and poured 3 mL of conc. H2SO4 and swirled to mix compounds. Then we refluxed the mixture for 1 hour. We let the solution cool and then decanted into a separatory funnel containing 50 mL of water and rinsed the round bottom flask with 35 mL of tert-butyl methyl ether and added that to a separatory funnel. We shook and vented thoroughly and drained the aqueous layer which contained a bulk of methanol and H2SO4. We washed the solution in the separatory funnel with 25 mL of water, followed by 25 mL of sat. sodium bicarbonate

In this synthesis, 2.0g of benzophenone was dissolved in 50ml isopropyl alcohol in 50ml Erlenmeyer flask. In this solution, one drop of glacial acetic acid was added. It was then filled with isopropyl alcohol up to the brim. After, the flask was stoppered using a well-rolled cork. It was ensured that very little air as possible was trapped inside the flask. It was tightly bind using a parafilm. The flask was inverted and exposed to sunlight outside the laboratory.

In 1984, the Cosmetic Ingredient Review (CIR) evaluated the safety of methyl, propyl, and butylparabens, stating that they were “safe for use in cosmetic products at levels up to 25%,” which is a generous limit, considering the approximate level for parabens ranges from .01 to 3%. However, there are still claims that parabens do more harm than good. The U.S. Environmental Protection Agency reported in December of 1999 “the chemical preservatives called parabens—methyl, propyl, butyl, and ethyl—displayed estrogenic activity in several tests.” Essentially, they found that parabens have the capability to mimic the body’s own hormones, which can lead to disruptions in the endocrine system, developmental and reproductive toxicity, allergies, and immunotoxicity. Even though parabens occur naturally in low levels in foods, like strawberries, blueberries, onions, carrots, etc, they are metabolized when consumed, making them less estrogenic. Yet, when the
