Effect of Garlic Powder on Duck Luncheon Meat Quality

In order to study the effect of garlic powder on the quality of duck luncheon meat and obtain the best quality products. 0%, 2%, 4%, 6% or 8% garlic powder was added into the production of luncheon meat. The quality of duck luncheon meat were measured by electronic nose, texture instrument, color difference analyzer and LF-NMR. Meanwhile, fuzzy mathematics sensory evaluation was used to comprehensively analyze the quality of duck luncheon meat. The results showed that there was a significant difference in the odor between duck luncheon meat with and without garlic powder added. With the increase of garlic powder addition, the various texture indicators and the L^* of duck luncheon meat showed a trend of first increasing and then decreasing, specially all indicators reached their peak when the amount of garlic powder added was 4%. At the same time, the a^* of luncheon meat color decreased, while b^* significantly increased overall (P<0.05). In addition, the content of non flowing water in luncheon meat showed a trend of first increasing and then decreasing, and reached the peak when the amount of garlic powder added was 6%. Garlic powder had a certain impact on the water distribution of luncheon meat. Based on fuzzy mathematics sensory evaluation results, the best addition of garlic powder was 4%. In conclusion, adding 4% garlic powder can improve the texture characteristics and flavor quality of duck luncheon meat, and improve the nutritional and economic value of luncheon meat.
