中文摘要：

藏花，从藏红花 sativusL 的花耻辱获得了，是最昂贵的食物香料之一。在高山的区域的藏花的介绍能帮助拓宽并且多样化山的活动多功能的农场，与经济和土地管理上的积极影响。根据 ISO 3632 (2010/2011 ) ，藏花能被分类进质量的三个范畴(我， II， III ) 取决于为它的典型颜色，风味和芳香负责的三主要代谢物的集中：Crocin， Picrocrocin 和 Safranal。这研究代表在与 spectrophotometry， HPLC，稳固阶段的 microextraction (SPME ) ，和色析法的分析与集体 spectrometry (GC/MS ) 相结合的气体评估的意大利的阿尔卑斯山脉生产的藏花的质量的第一调查。使用的藏红花 sativus 耻辱在中央意大利的阿尔卑斯山脉的不同区域在 2012-2013 生产了的实验在在 720 和 1200 m a.s.l 之间的高度被定位 ... 获得的结果与商业藏花相比。分析证实所有样品能根据 ISO 分类在第一个优秀范畴被分类。这高质量被 HPLC 分析也证实。而且， SPME-GC/MS 分析在藏花样品的芳香的侧面识别了一些差别，特别地关于 safranal 集中。对为本地市场的高质量的藏花生产的经济生存能力的一个初步的评价也被执行。我们的学习在在山区作为多功能的农场的收入的新来源的一个好候选人证实这庄稼的高山的区域关于藏花生产的优秀、经济的可持续性提供有效信息。

英文摘要：

Saffron, obtained from the flower stigmas of Crocus sativus L., is one of the most expensive food spices. The introduction of saffron in alpine areas could help to broaden and diversify the activities of mountain multifunctional farms, with a positive impact on economy and land management. According to ISO 3632（2010/2011）, saffron can be classified into three categories of quality（I, II, III） depending on the concentration of the three main metabolites responsible for its characteristic colour, flavor and aroma： Crocin, Picrocrocin and Safranal. This study represents the first investigation of the quality of saffron produced in the Italian Alps evaluated with spectrophotometry, HPLC, solid-phase microextraction（SPME）, and gas chromatographic analysis combined with mass spectrometry（GC/MS）. The experiments used Crocus sativus stigmas produced in 2012-2013 in different areas of the Central Italian Alps were located at an altitude between 720 and 1200 m a.s.l.. Results obtained were compared to commercial saffron. The analyses confirmed that all samples can be classified in the first quality category according to the ISO classification. This high quality is also confirmed by HPLC analysis. Moreover, the SPME-GC/MS analysis identified some differences in the aromatic profile of saffron samples, in particular regarding safranal concentration. A preliminary assessment of the economic viability of high quality saffron production for local markets was also performed. Our study provides valid information regarding the quality and economic sustainability of saffron production in the alpine area confirming this crop as a good candidate for a new source of income for multifunctional farms in mountain areas.
