Abstract: Some factors of hurdle technology, including far infrared radiation, ultraviolet ray, heating and cooling, are utilizedto control the quality of new-type concoct food. By sense and microorganism tests, it is found which hurdles adopted are moreeffective in products. The result indicates that dehydrating 20min with 1500W far-infrared-ray under the term of 95℃,sterilizing 25min with 235W ultraviolet-ray, and refrigerating under the term of 4℃ can kill harmful bacterium, and cannotinfluence the flavor and quality of products.

Key words: hurdle technology, concoct food, sterilization, flavor quality
