摘  要:
为探明适宜鲜切莲藕安全无毒的保鲜方法,以鲜切莲藕为研究对象,用不同浓度的Nisin溶液结合柠檬酸在低温下(5℃)对鲜切莲藕进行处理,用蒸馏水的处理进行比较,并评价其感官品质,测定其含水量、VC含量、多酚氧化酶(PPO)活性和藕片白度。结果表明,用0.5%柠檬酸和250mg/kg Nisin混合溶液对鲜切莲藕进行处理,保鲜效果最好。

摘  要:
In order to explore a safe and nontoxic fresh-keeping method of fresh-cut lotus roots,the author treated fresh-cut lotus roots with various concentrations of Nisin solution combined with citric acid at low temperature(5℃) taking distilled water as the control.Through the evaluation of sensory quality,determination of water content,Vc,polyphenol oxidase(PPO) activity and lotus whiteness,it could be concluded that 250 mg/kg Nisin solution mixed with 0.5% citric acid solution had the best fresh-keeping effect.
