鸡爪清洗工艺研究

以解冻鸡爪为原料,用氨水、碳酸钠、碳酸氢钠、氢氧化钠作为清洗加工助剂,以L值及感官评价为指标,得到鸡爪清洗工艺的适宜条件为:清洗助剂为碳酸氢钠、浓度1%、温度50℃、时间40 min,其L值可达到90.4;通过对其漂洗工艺进行研究,以感官评分为主要考查指标,0.2%的醋酸液漂洗40 min即可达到最佳的漂洗效果。

Study on Cleaning Process of Chicken Feet

With freezing chicken feet as the raw material,ammonium hydroxide,sodium carbonate,sodium bicarbonate,sodium hydroxide as the clean agent,the value of L and sensory evaluation as the studying index,the cleaning process of chicken feet was studied.The results showed that the optimum cleaning conditions are as follows: cleaning temperature 50 ℃,cleaning time 40 min and the concentration of sodium bicarbonate about 1%,the value of L 90.4.Studying on the rinsing processing,with sensory evaluation as the studying index,the results showed that the optimum rinsing conditions were as follows: the concentration of acetic acid 0.2%,rinsing time 120 min.
