一、项目概况

乳酸是重要的有机酸之一。分子式C3H603，分子量90.08。乳酸分子含有一个不对称碳原子，因此具有旋光性。L－乳酸为右旋性，而D－乳酸为左旋性。由于人体只具有分解L－乳酸的酶，故只能利用L－乳酸。近几年来，L－乳酸的研究与开发引起人们广泛的兴趣。乳酸在食品、医药、化工等方面都有广泛的用途。食品工业上用作软饮料的酸味剂和防腐剂，也用于调制酸奶。啤酒生产上用乳酸调节发酵液的PH。在医药上除直接作消毒剂外，由于乳酸钙、乳酸铁等乳酸盐在水中溶解度较大，无异味、易为人体吸收，因此是补充钙、铁元素的良好药品及营养添加剂。在化工上乳酸甲酯、乳酸丁酯及乳酸的高级酯和醚类是油漆、涂料、树脂的良好溶剂，塑料的增塑剂和润滑剂。L－乳酸还可用于生产聚L－乳酸。聚L－乳酸属于无毒的高分之化合物，具有生物相容性，可用于制造生物降解塑料，生物降解纤维，生物植片等。乳酸学名是a－羟基丙酸，广泛用于制药、酿酒、食品、饮料、保健品、造纸、制革、卷烟、油漆、油墨、电镀和塑料工业及输油管道防腐等。由于乳酸容易被人体吸收，直接参加体内新陈代谢，促进消化，具有防癌、抗癌、治癌及抗衰老作用，被称为“肌乳酸”，是生物化

乳酸分为D－乳酸、DL－乳酸和L－乳酸，D－乳酸用途很少，已基本不生产；DL－乳酸，有一定毒副作用，一般只做工业用。98年，世界卫生组织己将DL－乳酸列为禁止药用与食用。我国没有L－乳酸生产厂，暂用DL－乳酸代替，规定每人每天服用量不能超过10克，以避免产生有害影响。L－乳酸的用途广、品质优、正逐步取代DL－乳酸。八十年代，全世界需L－乳酸仅4万吨，九十年代初突破10万吨，目前己增加到70万吨左右。据国外预测，到2010年，全世界L－乳酸需要量将猛增到500万吨左右，特别需要指出，国外己开发成功用L－乳酸为原料生产乳酸树脂—肠衣线、胶卷、“双降解”塑料技术，即将投入大规模推广阶段，将会成为促进发展L－乳酸的强大推动力。

乳酸是以玉米、糙米、白薯、土豆淀粉为主要原料，通过发酵过滤、酸解、短程蒸馏等工序深加工而成的高级产品，工艺技术和环境要求较高，属高科技产品。目前，德国制造的“短程蒸馏”和日本生产的工艺设备，处于世界领先水平。我国的科研生产部门，通过对国内外乳酸生产工艺的系统调研，大胆消化吸收相关行业的工艺技术，一举攻克乳酸生产工艺存在的各种技术难题，提取率、色泽、浓度、纯净度等各项工艺技术参数均达到或超过发达国家的水平，处于世界领先水平。我国研

二、乳酸生产及市场预测

乳酸的生产方法有合成法与发酵法。目前国内发酵法生产乳酸均采用德氏乳杆菌为菌种，仅能积累D及DL型乳酸。D, DL型乳酸的价格是8000元／吨，乳酸钙7000元／吨。日本1997年己开始生产L－乳酸。国内从90年代开始陆续有L－乳酸发酵研究的报道。据资料报道，1993年全世界L－乳酸产量为1.5万吨左右，而需求量4万吨左右，且以每年平均10%的速度增长。国际市场主要是美国，荷兰、日本。1993年L－乳酸的价格是每吨2400～2800美元。目前是3000～3500美元／吨。

目前，全世界L－乳酸市场处于严重供不应求状态，是迅速发展L－乳酸生产的最佳时期。我国的L－乳酸年需求量在5万吨左右，生产是空白，全部靠进口供应。世界市场总需求量约70万吨，生产量只有30万吨，缺口很大，因此，各国纷纷规划扩大L－乳酸生产能力。美国近年建成投产3.4万吨规模的L－乳酸厂五个；荷兰建成投产5万吨规模乳酸厂一座；日本、澳大利亚等国也在积极安排扩大乳酸生产能力。 L－乳酸的市场正常售价为2.5万元/T左右，因我国所需L

我国的淀粉原料易得，能源用煤价廉。因此，建L－乳酸厂有其独特的优势。

L—乳酸属高科技生物化工产品，具有生物相融性，能完全被人体代谢吸收，被公认为安全物质，将替代D—乳酸和DL—乳酸广泛应用于食品、医药、化工、饲料、农药及皮革印染等领域，深受市场青睐。目前，世界L—乳酸的需求量13—15万吨/年，生产量为4万吨/年（我国年产量仅1000吨左右），并且需求量以每年10%的速度增长。由于聚乳酸对原料乳酸的需求量急剧增长，在今后的十年中，高纯度L—乳酸市场年需求可达45万吨。据美国有关专家预测，世界乳酸的潜在需求量应在250—300万吨。因此，L—乳酸市场潜力巨大。

L-乳酸是一种重要的有机酸，是21世纪最具发展前途的有机酸之一，它在人和哺乳动物体内起着调节肌肉活动和抗疲劳的制药作用。用它制成的乳酸盐已广泛应用于食品、医药、现代农业、日用化工等领域。它又能聚合成可降解物质聚乳酸。
