PACKING OF BUTTER

SYDNEY EXPERIMENTS

TAINTING CHECKED

SYDNEY, July 14

Trials with hemlock and hoop pine timbers for butter boxes, which have been carried out under the auspices ol the department of -■ agriculture here, have proved most successful. The official report on the subject says that the butter experimented with was packed under departmental inspection at the Wingham factory and since then has been in cold storage for two months. The report deals with the method of treating the boxes with sprays of casein and formalin, after which they are lined with triple foil aluminium and parchment and cardboard. The chief conclusion arrived at by the examiners was that the surface of all butter so packed was free from wood taint, except where wet papering was resorted to and there was very definite evidence of the value ol triple foil parchment in preventing both surface taint and the deepening of the surface colour of the butter. It was emphasised that dry papering gave the best results, while the proper selection of timber was as essential as satisfactory spraying.
