Sulphuring litchis is currently the only commercially viable means to control decay and retain colour, and the sole legal postharvest method according to current European legislation. During the season 2011/2012 different fumigation protocols in combination with packaging materials were applied on Madagascar litchis. The fruit was shipped to Europe and shelf life studies were conducted. While micro perforated bags proved not commercially viable, dual release Uvasys sulphur (SO2) sheets and smartPac liners performed very well in terms of fruit quality whilst maintaining SO2 residues less than 10 mg/kg in the litchi fruit flesh (European maximum residue limit).

Three different methods for analysing sulphur dioxide (SO2) in litchis were compared in terms of their sulphite analysis results. In terms of the set up and procedures the Monier Williams method applied in the European importing countries is very similar to the method applied in the exporting country Madagascar. The South African method with the shortest distillation time showed the highest uncertainty in terms of the colour change. The results of all three methods are considered to be comparable despite the discrepancies between the different methods.
