凯茵化工讯 德国马丁 路德大学研究人员发明了一种在热饮料里可自我溶解的牛奶胶囊，这种胶囊可方便地用在会议、飞机等快捷热饮供应场所，减少牛奶的塑料或纸壳包装。这项发明刊登在好近的《化学工程和技术》杂志上。

　　据马丁 路德大学的韦尔纳博士介绍，发明这项牛奶胶囊工艺的是其导师，马丁 路德大学工程科学中心的约阿希姆 乌利齐教授。牛奶胶囊是利用糖皮作为胶囊外壳，里面含有方糖、牛奶和炼乳，当牛奶胶囊接触到热液体时会自动溶解。

　　生产胶囊的方法相当简单，S先是将牛奶和糖按配方制成奶液，然后将热奶液注入成形模具中，再控制温度使其冷却。液体边缘多余的糖会随着温度变化产生结晶，并形成内含奶糖溶液的胶囊。整个生产步骤看似非常简单，但研究人员通过反复试验，才掌握了生产牛奶胶囊的好佳配方和冷却工艺。

　　目前已研制出甜味和微甜两种牛奶胶囊，还在研究原味牛奶胶囊，以满足不同口味的消费者需求。韦尔纳博士称，牛奶胶囊可按不同的形状生产，能在常温下存放，生产出的胶囊至少可保存3个星期。他们的工艺还可应用于其他液体胶囊，例如水果汁浓缩胶囊。

　　约阿希姆 乌利齐教授领导的团队多年前就开始研究胶囊制作工艺，美国亚什兰 并研究如何使结晶成形工艺适合药物胶囊等工业化应用。乌利齐教授称，新型的自我溶解胶囊具有很多潜在用途，如替代目前在会议或飞机航班上大量使用的塑料盒咖啡炼乳。乌利齐教授发明的这项工艺2015年已申请了 ，但还没有成为产品，大量廉价的牛奶胶囊工业化生产工艺还需要进一步完善。

Germany invented self-dissolving milk capsules

Kailin Chemical News Germany Martin & middot; Researchers at Luther University invented a self-dissolving milk capsule in a hot beverage that can be conveniently used in meeting places, airplanes and other quick hot drinks places to reduce the amount of milk Plastic or paper packaging. The invention is published in the recent Chemical Engineering and Technology magazine. According to Martin Luther University, Dr. Werner, who invented the milk capsule process, is the mentor to Martin Luther University Center for Engineering Science in Joachim & Middot; Ulrich professor. Milk capsule is the use of sugar as the capsule shell, which contains sugar, milk and condensed milk, milk capsules will automatically dissolve when exposed to hot liquid.

The method of producing capsules is fairly straightforward. The first step is to formulate the milk and sugar into a milk solution. The hot milk is then injected into the forming mold and the temperature is controlled to cool. The extra sugar on the edge of the liquid crystallizes as the temperature changes and forms a capsule that contains a solution of toffee. The whole production step may seem very simple, but researchers have learned the best recipe and cooling process for producing milk capsules by trial and error.

Two types of milk capsules, sweet and slightly sweet, have been developed. Natural milk capsules are also being researched to meet the needs of consumers of different tastes. According to Dr. Werner, milk capsules are available in different shapes and can be stored at room temperature to produce capsules that last for at least 3 weeks. Their process can also be applied to other liquid capsules, such as fruit juice concentrate capsules. The team led by Professor Joachim Ulrich started years ago to study capsule manufacturing processes and to study how to make crystalline forming processes suitable for industrial applications such as pharmaceutical capsules. Professor Ulici said the new self-dissolving capsules have many potential uses, such as replacing the plastic boxes of coffee condensed milk currently used extensively at conferences or on airline flights. The technology invented by Professor Ulici has been patented in 2015, but it has not yet become a product, and a lot of cheap milk capsules need further improvement in the industrialized production process.
