Modern methods of food production have altered radically from processes used in the past. Many food producing companies have invented their own improved techniques of cooking. Most of these procedures contain numerous different forms of chemical additives and one of the newest chemical substances that will enhance food flavor is monosodium glutamate (MSG). Even though it has no taste of its own‚ it intensifies considerably the taste of a wide variety of food as well as revealing flavors that could

How did the amount of Sodium Citrate‚ an anticoagulant‚ added to a Calcium Chloride solution affect the volume of the clots formed when a sodium alginate solution‚ a blood simulation‚ was introduced? Mackenzie Keesor (Fall Semester 2017-2018) Purpose The purpose of this experiment was to observe the differences in the formation of simulated blood clots when different amounts of sodium citrate‚ an anticoagulant‚ was added to the coagulation process‚ which would help gain information about the process

INTRODUCTION Sodium hypochlorite is considered one of the most efficient irrigant in endodontics 1-4. Due to its antimicrobial‚ tissue dissolving properties and low cost‚ it is one of the most widely accepted irrigant in Endodontic practice 5-8. Sodium hypochlorite as a solution is relatively an unstable compound. On exposure to organic compounds‚ heat‚ light‚ air and metals‚ the available chlorine ions reduce and there is subsequent loss of tissue dissolving and antimicrobial properties 9-10. Recent

Definition of Terms • Sodium Bicarbonate – Baking Soda • TRPM8 – Transient receptor potential cation channel subfamily M member 8 also known as the cold and menthol receptor 1‚ is a protein. TRPM8 is an ion channel‚ upon activation it allows the entry of Na+ (sodium) and Ca2+(calcium) ions to the cell that leads to depolarization and the generation of an action potential. This eventually

Prior to begin the experiment‚ preparation for some solutions is required to enhance the lab performance. The solutions needed are standardized potassium bromate‚ standardized sodium thiosulfate‚ and starch indicator. First‚ to prepare a starch indicator‚ pulverize 1g of soluble starch and add 15mL of water to make it as a paste-like substance. Dilute it with about 500mL of boiling water‚ and continue to heat until the mixture becomes clear. Cool it to room temperature and save it into a stoppered

NITRATION OF METHYL BENZOATE Purpose: The main objective of this experiment was to synthesize methyl nitrobenzoate from methyl benzoate‚ using the mixture of nitric and sulfuric acid by performing the process of electrophillic aromatic substitution. During this reaction‚ the combination of HNO3 and H2SO4 made a nitrating solution. The crystallization was done to accomplish pure product. The melting point and Thin Layer Chromatography (TLC) were performed to test the purity of the product. Using

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

Soaps used for cleaning purpose are sodium or potassium salts of long chain fatty acids‚ e.g.‚ stearic‚ oleic and palmitic acids. Soaps containing sodium salts are formed by heating fat (i.e.‚ glyceryl ester of fatty acid) with aqueous sodium hydroxide solution. This reaction is known as
