AFAIK Citric Acid was mixed with sodium metabisulphite to liberate sulphur dioxide as a sterilant. Nasty stuff capable of causing asthma attacks in the susceptible (as well as being poisonous). We used it in our early experiments with beer and wine making and often ended up with a coughing fit.
Were glad to discover Chempro SDP and it's successors which were both more effective and less chemically aggressive.
