مقایسه برخی خصوصیات فیزیکی و میکروبیولوژیکی نمونه های زعفران ایران با حد مجاز تعیین شده در استانداردهای ملی و بین المللی

چکیده مقاله

Deu to the importance of saffron as one of the Iran's export products, as well as having diverse medicinal properties and its wide application in the food industry, the evaluation of its physical properties and microbial contamination is of particular importance. Therefore, in this research, 25 saffron stigma samples from different regions of Iran were prepared and their physical and microbiological traits were measured in the first six months of 2024. The results showed that no samples contained artificial colorants and foreign matter related to the environment. In addition, Escherichia coli contamination was not observed in any of the stigma samples. The total number of microorganisms and molds in the stigma samples were much lower than the prmitted amounts in the national standard of Iran. Accordingly, all the examined samples were in full compliance with the national standard NO.259-1 and ISO 3632-1 in terms of physical characteristics and with the national standard No. 5689 in terms of microbiological properties.
