Time saving, accurate method for determining SO2 content in hop cones.Peer-reviewed article

P. HAUTKE, D. PETŘÍČEK

A new colorimetric method has been elaborated for determining SO₂ in hop cones. The method is more time saving and accurate than weighing analysis which is now chiefly used. The principle of the suggested new method is in a colour reaction between an absorbing solution containing SO₂ and fuchsine-formaldehyde reagent. The method is extremely sensitive and permits to determine very small quantities of SO₂ present in the investigated material.
