Influence of bamboo leaf antioxidants combined with atmosphere packaging on the preservation quality of fish-ball

In order to research the application of bamboo leaf antioxidants (AOB) in the preservation of surimi product, effects of adding different concentrations of bamboo leaf antioxidants combined with modified atmosphere packaging (MAP) on the bacterial count, TVB- N value, pH value, whiteness value, hardness, springiness, chewingness of fish-ball during storage process were investigated.Results showed that adding AOB could inhibit the microbial growth obviously, reduce the bacterial count and TVB-N value, increase the hardness, and maintain springiness and chewingness satisfactorily.Especially the 0.4g /kg AOB addition in fish ball combined with MAP (75% CO 2 + 25% N 2) had a good preservation effect and could extend shelf life to 39d.
