The objective of this study was to evaluate the qualities of emulsified meatballs where part of the lean pork was substituted with mechanically deboned bullfrog (Rana catesbeiana) meat (MDBM) during manufacturing and subsequently stored at 4C. Meatballs were manufactured by adding 0, 7.5, 15, 22.5 or 30% MDBM. The meatballs had higher moisture, lower protein and fat contents, darker color, lower water-holding capacity, higher cooking loss and softer texture as the MDBM usage level increased. The thiobarbituric acid and volatile basic nitrogen values of the products significantly (P < 0.05) increased, and the shear values, springiness and fracturability decreased as the MDBM usage level increased (P < 0.05). The products containing 7.5% MDBM had higher acceptable sensory characteristics than those samples containing more MDBM. In conclusion, emulsified meatballs that had 7.5% mechanically deboned bullfrog meat, substituted with equal quantities of the lean pork, were acceptable based on their physicochemical and sensory qualities. Practical Applications: Many animal by-products which are produced during processing are edible and valuable. How to utilize these by-products has become a great issue for the industry. In this study, high-quality proteins which were obtained from mechanically deboned bullfrog meat (MDBM) resulted in emulsified meatballs with acceptable qualities. More specifically, this information could make MDBM a possible material to substitute for part of the added lean meat in many emulsion-type meat products and increase products marketability because of lower raw ingredients' cost. This finding may be useful for both marine and domestic animal industries to make better use of this by-product. Lastly, this information can be used to enhance the potential reduction of animal wastes, which might pollute the environment.
