Alcohols in Flavor Chemistry: What Every Flavorist Needs to Know

Alcohols in Flavor Chemistry: What Every Flavorist Needs to Know

1. General Structure, Functionality, Reactivity & Stability Structure: Alcohols carry a hydroxyl (–OH) group bonded to an sp³ carbon. They're classified as primary (1°), secondary (2°), or tertiary (3°) depending on how many carbons attach to that carbinol carbon — this matters because it determines what oxidation can produce.

Enzymolysis in Flavor Chemistry: What the Society of Flavor Chemists Wants You to Know

Enzymolysis in Flavor Chemistry: What the Society of Flavor Chemists Wants You to Know

1. What enzymolysis means Enzymolysis is the cleavage of chemical bonds by enzymes, usually with water as the reacting molecule. In flavor systems, enzymolysis matters because it can either: Create desirable flavor notes by releasing aroma compounds or precursors, or cause flavor aging and shelf-life loss by degrading key

Recrystallization in Flavor Systems: Training Material for Flavorist Trainees

Recrystallization in Flavor Systems: Training Material for Flavorist Trainees

1. Introduction: What is Recrystallization? Recrystallization is the process by which a substance that was previously dissolved, melted, or present in an amorphous (non-crystalline) state forms crystals again. In flavor products, recrystallization most commonly involves: * Sugars * Polyols (sugar alcohols) * Organic acids * Salts * Encapsulating materials * Occasionally flavor ingredients themselves Although

Adsorption and Absorption of Flavor Compounds by Proteins, Carbohydrates, and Fats - A Flavorist Training Guide

Adsorption and Absorption of Flavor Compounds by Proteins, Carbohydrates, and Fats - A Flavorist Training Guide

Adsorption and absorption of flavor compounds are critical factors that determine flavor intensity, release, stability, and perception in food systems. Adsorption refers to flavor molecules attaching to the surface of food components, while absorption involves their penetration into the interior of a material. In practice, both processes often occur simultaneously.

Microbial Degradation in Flavor Products

Microbial Degradation in Flavor Products

Introduction Microbial degradation is the breakdown of flavor compounds by bacteria, yeasts, and molds through enzymatic activity. Unlike oxidation or thermal degradation, it is a biological process that can occur at room temperature in closed containers, even in systems that appear chemically stable. For a flavorist, this makes it a

Polymerization Reactions in Flavor Products

Polymerization Reactions in Flavor Products

Polymerization in Flavor Chemistry Polymerization is one of the main routes by which flavor compounds degrade over time. Unlike hydrolysis or simple oxidation to a single product, polymerization converts volatile, flavor-active monomers into larger, often non-volatile or off-odor species — so it's a central concern in
