Description

Only recently has bitterness control become of commercial importance to a food or pharmaceutical formulation chemist. Over the years, an increasing interest in more palatable food and beverage products with low fat and low sugar content has arisen, thus creating a market need for the control of bitterness perception.

This is the first, comprehensive treatment of this subject in book form. Organized primarily by ingredients or processing approaches affecting the bitter taste reduction or inhibition, this thorough review includes an in-depth and thoroughly referenced review of mechanisms, ingredients and applications of bitter taste reduction or inhibition.

Reviews

"The book is well-written and very readable, and it can be recommended as a reference text for all food scientists and technologists interested in the fundamentals of the bitter sensation and its perception."

-Dr. Bob Johnson, Chemist, for Food Science Australia

"I found the book quite fascinating, very informative, and timely. It is a book that I would recommend to those interested in the sensory property of bitterness and its control in food and beverages, as well as pharmaceutical products. I believe it to be a useful text book for all food libraries, and a 'must' in food development laboratories."

-Conrad Perara for Food Technology

Table of Contents

All chapters end with a section of references to the international literature on the chapter topic.
