In her recent letter Joanne D, said "Alcohol & vinegar, when distilled,
breaks proteins down. The fractions may remain, which is quite likely what
contributes to a celiac's sensitivity.?
The idea that distillation just breaks down proteins into small peptide
fragments is a very persistant misconception but is completely inaccurate.
Distillation does not break down proteins, it removes them. Because
proteins and even short peptide segments cannot evaporate, they are removed
with 100% efficiency in the distillation process. To anyone with a strong
background in chemistry, the idea that gluten peptide fragments could be
found at any level in a distilled product is ridiculous. What's more,
chemical analysis of the distillates confirm this. No amino acids or
peptide sequences can be detected in the distillation products.
While I do not dispute that some celiacs have an adverse reaction to
distilled vinegars, I am confident that this reaction is not caused by the
presence of gluten in the vinegar.
All the scientific evidence available agrees that distilled vinegars and
alcohols do not contain gluten.
