Glossary
Bioactive proteins added to honey by bees during the nectar-to-honey conversion process. Key enzymes include invertase (breaks down sucrose), diastase (breaks down starch), and glucose oxidase (produces hydrogen peroxide for antimicrobial protection).
Nectar straight from a flower is essentially sugar water. The transformation into honey requires biological processing that bees accomplish through enzyme addition. As a forager collects nectar into her honey stomach, glands in her head (hypopharyngeal glands) secrete enzymes directly into the nectar. These enzymes continue working throughout the entire processing chain: during the flight home, during mouth-to-mouth transfer to house bees, and while the honey cures in the comb.
Invertase (also called sucrase) breaks down sucrose, the complex sugar in nectar, into its two component simple sugars: glucose and fructose. This conversion is what gives honey its characteristic sugar profile and is the reason honey behaves differently from table sugar (which is pure sucrose) in cooking and baking.
Diastase (also called amylase) breaks down starches into simpler sugars. While honey itself contains very little starch, diastase activity is used as a quality marker for honey freshness and processing history. The international Codex Alimentarius standard specifies a minimum diastase activity level for honey, and levels below the threshold suggest the honey has been excessively heated.
Glucose oxidase produces small amounts of hydrogen peroxide when honey is diluted with water or wound moisture. This hydrogen peroxide gives honey its well-documented antimicrobial activity and is the primary reason honey has been used in wound care for thousands of years. In concentrated, undiluted honey, glucose oxidase is inactive; it only activates when the honey is thinned.
Enzymes are proteins, and proteins denature (lose their functional shape) when exposed to high temperatures. Pasteurizing honey at 145-160 degrees Fahrenheit destroys most enzymatic activity. This is one of the fundamental differences between raw and processed honey: raw honey retains its full complement of active enzymes, while heated honey is enzymatically dead.
Yes. Raw honey retains all the enzymes bees added during processing. Pasteurization and high-heat treatment denature (destroy) these enzymes. If enzymatic activity is important to you, always choose raw, unheated honey.
The primary health-relevant enzyme is glucose oxidase, which produces hydrogen peroxide that gives honey antimicrobial properties. Other enzymes aid digestion and nutrient absorption. These benefits are only present in raw, unheated honey where the enzymes remain active.
