CELLOPHANE PAPER AND WOOD-TAINT IN BUTTER.

An experiment was recently carried out at the Moturoa Grading Stores to ascertain whether Cellophane paper as ' a liner for Swedish timber butter-boxes could prevent contamination of the butter with the aroma of the wood. By courtesy of the Inglewood Co-operative Dairy Co., which use Swedish butter-boxes, four of the boxes were packed with butter from the same churning. Two boxes were lined with a wrapping consisting of Cellophane envelope and a wrapping of parchment-paper, and the other two boxes with the usual two wrappings of parchmentpaper.

The butters were regraded after two months' cold storage, and all found to be wood-tainted on the surface. Had this defect not been present the quality of the butters would have stood up to the original grade score of 95 points. The butters were afterwards held for about a week at ordinary temperatures in the grading-room, and both the specially wrapped and control butters were surface-tainted to much the same extent.

It is - therefore concluded that the use of Cellophane paper is of no practical value for the purpose indicated. _/)„•„ Division.
