Vinegar Volatile Organic Compounds: Analytical Methods, Constituents, and Formation Processes.

Area of Science:

• Food Science
• Analytical Chemistry

Background:

• Vinegar, a globally consumed acid condiment, is categorized into fruit and cereal types.
• Both vinegar types exhibit distinct aroma and flavor profiles attributed to their unique volatile organic compounds (VOCs).

Purpose of the Study:

• To systematically review the analytical methods, types, and formation mechanisms of vinegar volatile organic compounds (VVOCs).
• To provide a comprehensive understanding of the factors influencing vinegar's aroma and flavor.
• To identify future research directions in VVOCs analysis and application.

Main Methods:

• Literature review of scientific databases for studies on vinegar VOCs.
• Categorization and summarization of analytical and identification techniques for VVOCs.
• Analysis of VVOCs types and their formation pathways.

Main Results:

• Overview of global vinegar categories and their distribution.
• Summary of various analytical methods used for VVOCs identification.
• Detailed description of VVOCs types and their formation processes.

Conclusions:

• This review is the first to systematically consolidate research on VVOCs analytical methods, types, and formation.
• Enhanced understanding of VVOCs will aid in controlling and optimizing vinegar production for desired sensory qualities.
• Future research should focus on advanced analytical techniques and the intricate biochemical pathways of VVOC formation.
