摘要
柠檬酸一种重要的有机酸,柠檬酸用途非常广泛,用于食品工业占生产量的75%以上,可做食品的酸味剂、抗氧化剂等;用于医药工业占12%,在医药方面作用明显,可作抗凝血剂、解酸剂;用于化工工业18%,可作缓冲剂、络合剂、金属清洗剂等。目前柠檬酸主要通过微生物发酵进行生产,是微生物在工业上应用的代表。
Citric acid is an important organic acid,citric acid is widely used in the food industry,accounting for more than 75% of the production capacity,can be used as food sour,antioxidants etc. Used in the pharmaceutical industry,accounting for 12%,the role of drugs in the obvious,anticoagulant,acid hydrolysis agent; used in the chemical industry 18%,as a buffer agent,complexing agent,metal cleaning agent etc. At present,citric acid is mainly produced by microbial fermentation. It is a representative of the application of microorganisms in industry.
