Biopolymers provide a renewable source of structuring agents for a variety of potential uses in food, pharmaceutical and other applications that require bio-compatibility. Swollen biopolymer particles of sub-millimetre size are particularly useful as they combine macroscopic structure formation with an ability to flow and a desirable soft solid texture. Two limitations to the current utilisation of biopolymer particles are that they either cannot be predictably produced direct from a dried form, or if they are (e.g. cooked starch granules), there is a lack of scientific understanding that limits use of natural sources without subsequent chemical modification. This project will provide the science & technology to overcome these limitations.

生物聚合物为食品、制药和其他需要生物相容性的应用中的各种潜在用途提供了结构化试剂的可再生来源。亚毫米尺寸的Swedish生物聚合物颗粒是特别有用的，因为它们将宏观结构形成与流动能力和期望的软固体质地相结合。目前利用生物聚合物颗粒的两个限制是，它们不能直接从干燥形式可预测地生产，或者如果它们是（例如蒸煮的淀粉颗粒），则缺乏科学理解，这限制了在没有随后的化学改性的情况下使用天然来源。该项目将提供克服这些限制的科学和技术。
