Exposure to a very high concentration of benzene can be deadly. This study therefore aimed at investigating the comparative effects of sodium benzoate and local spices Syzgium aromaticum L.
Benzene was discovered by Michael Faraday Sodium benzoate chemical changes at the However, research conducted by the U. Storax is a resin exuded by a type of sweetgum tree and balsam is another plant resin. The benzoate form of the chemical is converted into the acid form in our stomach and absorbed into the body through the lining of the small intestine.
A skin rash, itching, a runny nose, and congested airways are possible symptoms of a sodium benzoate pseudoallergy. Material and Methods Materials Mature tamarind T. While tamarind-based drinks are produced by industries in many countries where tamarinds grow, none exists in Nigeria.
Some people develop allergy-like symptoms when they are exposed to sodium benzoate. Since this discovery, many manufacturers have reformulated their products to reduce the amount of benzene.
Improved tamarind beverage produced without the inclusion of sodium benzoate was stable for 3 and 5 weeks at room and refrigerated temperatures, respectively.
It is also used as a preservative in medicines and cosmetics. In contrast, benzoic acid has a significantly lower water solubility profile. Natural occurrence[ edit ] Sodium benzoate occurs naturally, along with benzoic acid and its esters, in many foods. Many other influences are at work but this at least is one a child can avoid.

The chemical may play a role in increasing hyperactivity in children, however, although this is unproven. These effects include a headache, dizziness, vomiting, muscle tremors, a rapid or irregular heartbeat, drowsiness, and loss of consciousness.
Sodium benzoate extended the shelf life of the improved tamarind beverage to 6 and 13 weeks, respectively, at room and refrigerated temperatures. If the environment is not sufficiently acidic and sodium ions are present—as they often are—sodium benzoate predominates.
Benzoic acid can enter the body through the skin as well as the digestive and respiratory tracts. This product contains gum benzoin and alcohol as well as storax, Tolu balsam, and aloe. Department of Agriculture USDA has found that in small doses and mixed with food, sodium benzoate is not deleterious to health.
Samples were analyzed, at regular intervals, for chemical, sensory, and microbiological qualities. Source Benzoic Acid and Benzoates Benzoic acid and benzoates are common additives to food, drinks, and other products.
Tamarind fruits are only processed into beverage by indigenous people located in Northern Nigeria, despite the fact that tamarinds grow in some parts of southwest Nigeria.
It can also weaken the immune system.
Although benzene is often represented by this diagram, chemists have discovered that the bonding between the atoms is not as simple and clearcut as shown in the illustration. The benzene molecule is a six sided ring, as shown in the diagram above.
Production of tamarind beverages Tamarind beverage was prepared according to the improved method of Adeola and Aworh Almost every diet soft drink contains sodium benzoate, as do some wine coolers a… Sodium Bicarbonate - Use In Antacids, Use In Baking - Use in fighting fires [next] Citing this material Please include a link to this page if you have found this material useful for research or writing a related article.
This is worrying, since benzene is a carcinogen. If the intracellular pH falls to 5 or lower, the anaerobic fermentation of glucose through phosphofructokinase decreases sharply,  which inhibits the growth and survival of microorganisms that cause food spoilage.
Benzoates are derived from benzoic acid and are more commonly used as food preservatives than the acid. Cinnamon contains benzoic acid. Benzene is a carcinogen. Content on this website is from high-quality, licensed material originally published in print form. Maraschino cherries are often preserved with sodium benzoate.Consulting Chemists Institute Introduction The Consulting Chemists Institute was contracted by a local food manufacturer to determine if sodium benzoate, a common food preservative, undergoes significant chemical changes at the pH level encountered in the acidic environment of the stomach.
Benzoic acid and sodium benzoate 3 industry. They are selected because of their expertise in human and environmental toxicology or because of their experience in the regulation of chemicals.
Boards are chosen according to the range of expertise required for a meeting and the need for balanced geographic representation. Sodium Benzoate (NF/FCC) Revision Date May Sodium benzoate Disposal considerations Waste Disposal Methods Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste.
Chemical waste generators must also consult local, regional, and. Sodium benzoate is a substance which has the chemical formula NaC7H5O2. It is a widely used food preservative, with an E number of E It is the sodium salt of benzoic acid and exists in this form when dissolved in water.
It can be produced by reacting sodium hydroxide with benzoic acid. Nov 15, · The effect of sodium benzoate on the quality attributes of improved tamarind beverage during storage was investigated. Tamarind beverages were produced according to a previously reported improved method, with or without chemical preservatives ( mg/ mL sodium benzoate).
Sodium benzoate is the sodium salt of benzoic acid. It is an aromatic compound denoted by the chemical formula C 7 H 5 NaO 2 with a molecular weight of In its refined form, sodium benzoate is a white, odorless compound that has a sweet, astringent taste, and is soluble in water.
Sodium benzoate has antimicrobial characteristics, and is .Download
