Sulfuric acid can be synthesised by piping sulfur dioxide (SO2) gas into an oxidiser such as peroxide (or nitric acid).

And .... Sulfur dioxide can be generated by dripping hydrochloric acid into a solution of sodium metabisulfite (Na2SO5).
No heating is required, simply slowly add the acid to the water solution, and pipe the resulting gas into a container of peroxide.

Here in Australia, food grade peroxide is available to the public (used for making cheese and adding to tank water for safe drinking). Food grade sodium metabisulfite is available in many supermarkets as a steriliser for home brewing beer.

To do this, you will first have to make your own food grade hydrochloric acid by following the instructions HERE (http://forum.alchemyforums.com/showthread.php?3817-Make-Food-Grade-Hydrochloric-Acid).

Once you have your ingredients, construct your apparatus, and make your sulfuric acid.

After youre done piping gas into the peroxide, heat it up which will break down the peroxide and leave you with food grade sulfuric acid, free from any toxic impurities.

Be Safe

I suppose the term Food grade sulfuric acid it is a bit of an oxymoron.
