Table 16.1. Aspartame 100 Saccharin 550 Sucrolose 600 Alitame 2000 Table Table 16.1: Artificial Sweeteners Aspartame is the most successful and widely used artificial sweetener. It is roughly 100 times as sweet as cane sugar. It is methyl ester of dipeptide formed from aspartic acid and phenylalanine. Use of aspartame is limited to cold foods and soft drinks because it is unstable at cooking temperature. Alitame is high potency sweetener‚ although it is more stable than aspartame

11 aromatic compounds‚ 18 acids and 10 other compounds. Acids were the most volatile compounds in 14 fish sauce samples. Volatile acid class represents the major constituents for the sauce samples and can be produced as a result of either lipolysis or from amino acid metabolism in terms of valine deamination [13]. Volatile compounds in the most of samples were identified trimethylamine (TMA)‚ acetone‚ 1-propanol‚ acetic acid‚ 2-butanone‚ benzene‚ propanoic acid‚ 3-methyl-1-butanol‚ 2-methyl-1-butanol

whereas the longer chain alcohols are insoluble in water. In general a molecule which is more compact (i.e.‚ more branched) will be more soluble in water and will have a lower boiling point than the straight chain isomer. Phenols are aromatic alcohols‚ in which R is an aromatic ring. This experiment will demonstrate some of the properties of alcohols and phenols. Although alkyl alcohols have an -OH group‚ they do not ionize in water‚ whereas phenols ionize like acids (donating a proton to water). The -OH

THEORY: In this experiment‚ Panacetin‚ a pharmaceutical preparation will be separated from its components by making use of their solubilities and acid-base properties. Panacetin contains aspirin‚ sucrose and an unknown component that may be either acetanilide or phenacetin. Of the three components‚ only sucrose is insoluble

April 04‚ 2014 Fisher Esterification Introduction: Esters are one of the most common derivatives of carboxylic acids and are widely distributed in both nature and industry. A Fischer Esterification is the formation of an ester and water from alcohol and an acid. It is the simplest means of synthesizing an ester and requires the reaction of a carboxylic acid and an alcohol. The general reaction of Fischer esterification is‚ CH3CO2H + ROH ↔ CH3CO2R + H2O (reaction1) CH3COOH + ROH ↔
