BUTTER TESTS

I.MPOR TANT DISCOV ERIES. (United Press Association—By Electric Telegraph—Copyright). LONDON. Oct. 11. It is understood that two tests have ijerently been concluded ibv the National Institute of Dairying Research at Sinn field by Dr AY. L. Davies, under the auspices o.f the Empire Marketing Board, which have resulted in important discoveries' affecting Australia’s butter industries. Dr Dut ies’ researches have been concerned with the oxidisation and potential “fishiness” . occurring to butter in transit, which defects last year cost the Australian producers at least £7OOO. Dr Davies, in investigating the deterioration of Australian butter, discovered that the minutest metallic substance in contact with milk can damage an entire butter consignment. He found also that immunity from fishiness, which leads to eventual discolouring, can only he ensured hv the elimination of all possibility of such contamination.

Dr Davies has further discovered a method of testing butter before it h exported so as to enable it to he determined what period, almost to within a day, that the butter will carry

without deterioration. This will enable the perfect, grading of butter ior export. besides also deriding what huttors should be used solely lor home consumption.
