Ankom Technology (www.ankom.com) described its TDF Dietary Fiber Analyzer, which automates AOAC 991.43/AACC 32.07.01 for determination of total dietary fiber (TDF) as well as soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) individually. The instrument automates the addition of chemical solutions, enzymes, and rinses and controls the temperatures and agitation levels throughout the process, eliminating the need for multiple water baths and freeing up counter space. Use of advanced filter bag technology increases the filtering surface area, which reduces the time needed to filter samples and eliminates the use of vacuum flasks and crucibles. The instrument also allows the user to bypass capturing the IDF fraction and just capture TDF. The final filtrate can be captured for further testing. The unit can run 18 samples per day.

C.W. Brabender Instruments (www.cwbrabender.com) exhibited its TS-5000Z Taste Sensing System, which imitates the patterns of the human tongue by converting the taste of foods and beverages into numerical data. The instrument has sensors that consist of an artificial lipid membrane, similar to that of the human tongue, which causes electrostatic or hydrophobic interactions with various taste substances. The difference in potential between the sample liquid and a reference solution represents initial taste (i.e., the taste perceived when food first enters the mouth). After the sensors are lightly washed, the difference in potential represents the aftertaste (i.e., the taste that remains in the mouth after the food has been swallowed). The outputs from the sensors are converted into taste information by multiple regression analysis and principal component analysis. The data can be graphically presented in various types of charts, including radar charts, 2-dimensional and 3-dimensional scatter plots, contour charts, bubble charts, transient response graphs, line graphs, and measurement data displays.
