Acidity of lemon tea?
« on: 21 December, 2012, 07:26:15 am »
How acidic do you reckon 'lemon' flavoured green (teabag) tea is?  mrs ao has problems with cracked tooth enamel and I was just wondering about acidity of the Clipper tea she usually drinks.

Tea in itself seems to be quite good for teeth, it contains fluoride for a start...

Possibly worth checking the ingredients for citric acid, though it's probably a sight better that the crap most people drink these days!

Ingredients suggest it may be OK...   Green Tea, Natural Lemon Flavour, Lemon Peel (1%).

As a bored student I did some experimenting with the products of the Chemistry block vending machine and discovered that the Lemon tea dissolved some of the polystyrene cup.  :o

Citric acid probably counts as 'natural lemon flavour', given that it's natural and comes from lemons though :)

If she drinks it through a straw it'll take the tea behind her teeth and avoid the problem.

I thought that one had been disproved by SCIENCE?

The clipper lemon green tea is very low in acid, imo, with a faint lemon flavour not emanating from the juice.

pH is a logarithmic scale, so very small amounts of unbuffered citric acid could be harmful for the teeth.
Sodium citrate is used as a buffer, which means a pH can be controlled within a narrow range.
However all solutions of citrate are acidic.
I have no idea what the pH of this lemon tea is.
Lemon oil will impart a lemony flavour without being acidic.
