pectin

Lemma: pectin
Etichetta di dominio: EN
Etichetta grammaticale: n.
Definizione: Pectin is a complex substance which forms part of the cell wall in plants […] [and which] is composed of long chains of galactonuric acid whose side chains of methyl alcohol are the chief source of the trace amounts of methanol found in all wines. 1
Nota: When making wine, a haze in the finished product could result from pectin. Fruits used for wine contain pectin in them naturally. This pectin gives jams and jellies their body, but it does nothing for the clarity of your wine. Most of the pectin in wine disperses through fermentation, but should a fruit with a high amount of pectin in it be used to make the wine, an excess of pectin remains after fermentation, resulting in a cloudy pectin haze. 2
Contesto: The most common cause of a haze in wine is the presence of pectin, which forms gelatinous solutions in the wine. 3
