Potential of Conductance Measurement for Lard Detection
نویسنده
چکیده
_ Relative cheapness of lard cause it is often mixed to reduce production cost in the food industry. Therefore, it is important to purpose a detection lard contamination. In this paper, we evaluate the potential and some limitation of conductance measurement for lard detection. The study was focused to identify frequency of the edible fats adulteration. Beef tallow, chicken fat, goat fat, and palm oil were mixed with different proportions of lard. These samples were analyzed by the method of dielectric spectroscopy in range 1.0-5.0 MHz. Frequencies of measurement range from 3.8-5.0 MHz in room temperature (26-27C) shown difference of conductance between edible fats. This technique can be developed to rapid detection of lard in food industry. Index Term __ Conductance measurement, lard detection, resonance frequency.

Animal fats (camel, sheep, goat, rabbit and chicken) and vegetable oils (corn, sunflower, palm oil and olive oil) were substituted with different proportions (1, 5, 10 and 20%) of lard. Fatty acid composition in TG and 2-MG were determined using lipase hydrolysis and gas chromatography before and after adulteration. Results indicated that, genuine lard had a high proportion (60.97%) of the tota...
