Test which consists in measuring the insoluble or visible dirt in milk by filtering a pint of milk through a firm cotton disk placed over an opening 1 in. in diameter.
Notes :
Several types of sediment testers are available; this makes the test simple to run. The amount of sediment in the milk can be given a numerical rating by comparing the disks with a photographic standard. The returning of sediment test disks to milk producers whose milk was not so clean as it should have been has been effective in improving milk supplies.
Upon receipt of the milk at the processing plant several inspections and tests may be run to control the quality of the incoming product. Some of these tests may have been done at an earlier receiving station. These tests commonly include determination of fat and total solids by chemical or physical analyses; estimation of sediment by forcing the milk through filter pads and noting the residue left on the pad; determination of bacterial counts, especially total count, coliform count, and yeast and mold count; determination of freezing point as an index to possible water pick-up; and evaluation of milk flavor. Under special circumstances tests for detection of antibiotic residues from treated cows, and for pesticide residues that may get into the milk from the cow's feed or from other farm use also may be made.Terme :
