Acrylamide (AA) contents in 294 snack foods including cereal-based, root- and tuber-based, and seafood-based foods, nuts, dried beans, and dried fruits purchased in Taiwan were determined by gas chromatography-mass spectrometry in this study. The highest levels of average AA content were found in root- and tuber-based snack foods (435 μg/kg), followed by cereal-based snack foods (299 μg/kg). Rice flour-based, seafood-based, and dried fruit snack foods had the lowest average AA content (<50 μg/kg). This is the first large surveillance of AA content in snack foods in Taiwan. The results could provide important data regarding intake information from the snack foods. In addition, the results showed a great diversity of AA content in snack foods prepared from different ingredients. Rice- and seafood-based products had much lower AA than those made from other ingredients. This information could constitute a good reference for consumers to select products for healthy snacking.

In this paper a new horizon-based shipborne camera video stabilization algorithm is implemented. First, the edges are obtained by Canny operator, then effective lines are obtained by Hough transform. In order to get the horizon within the existing lines, a fast filter-based method detecting the lines location differences is proposed, and image stabilization is implemented by the difference with the current horizon and base horizon. Experiments show that the algorithm can meet the real-time requirements, and can achieve the better image stabilization effect even in the conditions of bad light and fogs.
