中文摘要: 以新鲜甘蓝为原料,采用自然干法腌制、自然湿法腌制、纯种干法腌制、纯种湿法腌制4 种方式制作泡甘蓝,腌制过程中测定泡甘蓝的总糖、还原糖、总酸、pH 值、氨基酸态氮、亚硝酸盐、乳酸菌数和大肠菌群数的含量变化,分析腌制方式对泡甘蓝的品质影响。结果表明:纯种湿法腌制可提高泡甘蓝发酵速度,缩短腌制时间,对最终产品总糖含量、还原糖含量、大肠菌群数和pH 值无明显影响,产品氨基酸态氮较其它方式稍有降低,产品乳酸菌数较其它方式稍有增高,纯种湿法腌制可使泡甘蓝的亚硝盐含量含量从高峰值快速降到稳定值0.36 mg/100g,纯种湿法感官评分值最高为90.98。综合各项指标,纯种湿法腌制泡甘蓝具有明显的优势。
Abstract:Using fresh cabbage as raw material to make fermented cabbage ,pickling methods such as natural dry pickling,natural wet pickling,pure-culture dry pickling and pure-culture wet pickling was studied.In the course of pickling,the total sugar,reducing sugar,total acid,pH value,amino acid nitrogen,nitrite of fermentted cabbage,lactic acid bacteria count and coliforms bacteria count were determined and analyzed.The results showed that the pure-culture wet pickled cabbage could increase the fermentation speed,shorten the pickling time,and had no obvious effect on the total sugar and reducing sugar conten,t,coliforms bacteria count and pH of the pickled products,and had slightly lower contens for the amino acid nitrogen than that of other methods.The peak value of nitrite content was reduced fastly to 0.36 mg/100 g for pure-culture wet pickling.sensory score of pure-culture wet pickling was 90.98.In general,pure-culture wet pickling cabbage had obvious advantages.
