Erich Ziegler laid the foundation for 'Flavourings' with his book 'Die naturlichen und kunstlichen Aromen'. He contributed this expertise to the first edition, when in continuation of the family tradition, 'Flavourings', addressed an international audience under the auspices of Herta Ziegler in 1998. With the present second edition, dedicated to Erich Ziegler on the occasion of his 80th birthday, she presents an updated version of her comprehensive overview of the flavour & fragrance industry.

Herta Ziegler studied chemistry at the University of Bayreuth, Germany, focusing on analytical chemistry. She soon discovered her profound interest for the organic analysis of complex natural matrices, which were also the subjects of her master and doctoral theses with Prof. Gerhard Spiteller. Her position as head of corporate research at Erich Ziegler GmbH since 1992 allowed her to combine her penchant for citrus oils with her professional activities. Less
