建昌板鸭发酵微生物环境的研究

试验以建昌板鸭为研究对象,研究板鸭发酵的微生物环境(即对板鸭进行理化检验)。根据与板鸭微生物环境有关影响因素及板鸭的卫生标准确定7个理化特性检验指标(水分活度、酸价、过氧化值、pH、氯化钠含量、亚硝酸钠、游离氨基态氮)。通过检测得出结果:水分活度越来越低,过氧化值和酸价及氨基酸态氮越来越高。pH和含盐量先降后升,而亚硝酸盐含量相反,先升后降。并根据检测结果对板鸭微生物环境进行分析。实验结果表明,板鸭内部的微生物环境影响绝大多数微生物的生长。

Study on the Environment of Microorganism during the Fermentation of Jian Chang Dry-cured Duck

The Jian Chang Dry-cured Duck was used to study the environment of microorganisms during fermentation in the experiment.Effects of facts such as water-activity,pH value,acid value,peroxide value,free amino nitrogen,salt,nitrites was inspected during the fermentation.The result of inspection showed that the value of water-activity were reducing by time.Acid value,peroxide value,free amino nitrogen were growing by time.Salt and pH were first increased and then decreased.Nitrites were opposite.Analysis on the ...
