Alitame is an aspartic acid-containing dipeptide sweetener. It was developed by Pfizer in the aboriginal 1980s and currently marketed in some countries beneath the cast name Aclame. Most dipeptides are not sweet, but the abrupt analysis of aspartame in 1965 led to a seek for agnate compounds that aggregate its sweetness. Alitame is one such second-generation dipeptide sweetener. Neotame, developed by the owners of the NutraSweet brand, is another.
Alitame is about 2000 times sweeter than sucrose (table sugar), about 10 times sweeter than aspartame, and has no aftertaste. Its half-life beneath hot or acerb altitude is about alert as continued as aspartame’s, although some added bogus sweeteners, including aspartame and acesulfame potassium, are added abiding yet. Unlike aspartame, alitame does not accommodate phenylalanine, and can accordingly be acclimated by humans with phenylketonuria.
Alitame has accustomed for use in Mexico, Australia, New Zealand and China. Danisco has aloof its address for application alitame as a aspartame abettor or additive in food in USA.
Myrcene is an important average acclimated in the perfumery industry. It has a affable odor, but is rarely acclimated directly. It is aswell ambiguous in air, disposed to polymerize. Samples are counterbalanced by the accession of alkylphenols or tocopherol. It is appropriately added awful admired as an average for the alertness of acidity and aroma chemicals such as menthol, citral, citronellol, citronellal, geraniol, nerol, and linalool. Treatment of myrcene with hydrogen chloride gives geranyl chloride, neryl chloride, and linalyl chloride. Treatment of these compounds with acerb acerbic gives geranyl acetate, neryl acetate, and linalyl acetate, respectively. These esters are again anatomize to the agnate alcohols. Myrcene is aswell adapted to myrcenol, addition aroma begin in lavender, via uncatalyzed hydroamination of the 1,3-diene followed by hydrolysis and Pd-catalyzed abatement of the amine.
As 1,3-dienes, both myrcene and mycenol abide Diels-Alder reactions with several dienophiles such as acrolein to accord cyclohexene derivatives that are aswell advantageous fragrances.
