Abstract:The effect of electron beam(EB) irradiation on instant chicken feet was examined,and the qualities of the instant chicken feet treated at different doses were analyzed in terms of thiobarbituric acid reactive substances(TBARS),Total Volatile Basic Nitrogen(TVB-N),flexibility,juice loss rate,sensory quality and total bacterial count.The results showed that instant chicken feet treated with dose of 6.0 kGy,and stored for 180 days,the total bacterial count of chicken feet was 4 300 cfu/g and the D10 value of colony number was determined to be 1.84-2.22 kGy.There was significant difference in TBARS value between irradiation and non-irradiation when the doses of EB irradiation were upon 6.0 kGy,while there was no significant difference in TVB-N,and there was no there was no significant difference in juice loss rate and flexibility when the dose was less that 8.0 kGy;irradiation had some effects on sensory quality,but the effects were very small.After 180 days of storage at room temperature,the results show that EB irradiation could significantly reduce and control the instant chicken feet microorganism,and its shelf-life could be prolonged.
