Paw San rice, also known as “Myanmar pearl rice”, is considered the highest quality rice in Myanmar. There are considerable differences in terms of the premium commercial value of Paw San rice, which is an incentive for fraud, e.g. adulteration with cheaper rice varieties or mislabelling its geographical origin. Shwe Bo District is one of the most popular rice growing areas in the Sagaing region of Myanmar which produces the most valued and highly priced Paw San rice (Shwe Bo Paw San). The verification of the geographical origin of Paw San rice is not readily undertaken in the rice supply chain because the existing analytical approaches are time-consuming and expensive. Therefore, there is a need for rapid, robust and cost-effective analytical techniques for monitoring the authenticity and geographical origin of Paw San rice.

利用近红外光谱、顶空气相色谱-离子迁移谱和化学计量学对缅甸不同地区种植的 Paw San 稻进行地理区分

波山米，又称“缅甸珍珠米”，被认为是缅甸最优质的大米。 Paw San 大米的优质商业价值存在相当大的差异，这会助长欺诈行为，例如掺假较便宜的大米品种或错误地标记其地理来源。 Shwe Bo 区是缅甸实皆地区最受欢迎的水稻种植区之一，生产最有价值和价格最高的 Paw San 米（Shwe Bo Paw San）。由于现有的分析方法既耗时又昂贵，所以在大米供应链中很难对 Paw San 大米的地理来源进行验证。因此，需要快速、稳健且具有成本效益的分析技术来监测 Paw San 大米的真实性和地理来源。
