Bitterness: Perception, Chemistry and Food Processing
Mayelana nale ebook
The authors provide a thorough review of bitterness that includes an understanding of the genetics of bitterness perception and the molecular basis for individual differences in bitterness perception. This is followed by a detailed review of the chemical structure of bitter compounds in foods where bitterness may be considered to be a positive or negative attribute. To better understand bitterness in foods, separation and analytical techniques used to identify and characterize bitter compounds are also covered.
Food processing can itself generate compounds that are bitter, such as the Maillard reaction and lipid oxidation related products. Since bitterness is considered a negative attribute in many foods, the methods being used to remove and/mask it are also thoroughly discussed.
