용도
출처
Reported found in fresh apple, butter, cheddar cheese, coffee, cocoa, honey, wheat bread and wine
용도
Acetoin is a produced via fermentation of wines, dairy products and sugars by fermentive bacteria. Acetoin is used in food flavoring and fragrances and is also found in some fruits and vegetables.
일반 설명
A light-yellow colored liquid. Slightly denser than water. Hence sinks in water. Boiling point 280°F. Flash point between 100 and 141°F. Used to make other chemicals.
