Prospect on discerning technology of swill - cooked dirty oil
Several major common problems in the studies of discerning technology for swill -cooked dirty oil were analyzed and prospected. The conception of "swill - cooked dirty oil" was still not unified, so the conception of "waste cooking oil" was more accurate. Swill -cooked dirty oil was reused oil with the common feature of deep oxidation. Characteristic substance might not exist in the swill - cooked dirty oil, and its identity could hardly be determined by detection. Swill - cooked dirty oil was far from standard subject,and the adulteration could be quantitative detected by no means. Multiple - indicator system which combined endogenous quantity differences index with exogenous exclusive index was an inevitable trend. Fast identification technique for the swill - cooked dirty oil could complement the arbitration technology, but could not be put into application independently. Presently,it was necessary to pay equal attention to administrative supervision and the technical detection, and the screening detection technology should be developed and applied as soon as possible.
