Crocus Sativus L

Saffron is derived from the stigmas of the flower Crocus sativus L. The drying process is the most important post-harvest step for converting C. sativus stigmas into saffron. The aim of this review is to evaluate saffron’s post-harvest conditions in the development of volatile compounds and its aroma descriptors. It describes saffron’s compound generation by enzymatic pathways and degradation reactions. Saffron quality is described by their metabolite’s solubility and the determination of picrocrocin, crocins, and safranal. The drying process induce various modifications in terms of color, flavor and aroma, which take place in the spice. It affects the aromatic species chemical profile. In the food industry, saffron is employed for its sensory attributes, such as coloring, related mainly to crocins (mono-glycosyl esters or di-glycosyl polyene).

The present study evaluated the reliability of the ISO/TS 3632-2 UV-Vis spectrometric method for saffron classification, making experiments on saffron samples to which were added increasing concentrations of common saffron spice adulterants (safflower, marigold and turmeric). The results showed that the ISO/TS 3632-2 method is not able to detect addition of up to 10-20%, w/w, of saffron adulterants. For additions from 20 to 50%, w/w, of the three adulterants, saffron was classified in a wrong category; addition of higher than 50%, w/w, determined variations in the investigated parameters that did not allow identification of the product as “saffron”. In all cases, the method did not permit the recognition of the nature of the adulterant. On the contrary, the specificity of the HPLC/PDA/MS technique allowed the unequivocal identification of adulterant characteristic marker molecules that could be recognized by the values of absorbance and mass. The selection of characteristic ions of each marker molecule has revealed concentrations of up to 5%, w/w, for safflower and marigold and up to 2% for turmeric. In addition, the high dyeing power of turmeric allowed the determination of 2%, w/w, addition using exclusively the HPLC/PDA technique.

Introduction: Candida albicans survival tests on PCV carriers are necessary for the proper determination of the effectiveness yeasticidal activity of disinfectants. C. albicans is a pathogenic microorganism that causes fungal diseases and therefore its spread in the medical and non-medical areas should be limited by disinfection. Methods: Survival of C. albicans was estimated with using principles of PN-EN 16615 standard. Suspension of C. albicans with interfering substances (0,3 g/l bovine albumin) was dry on PCV carriers under a laminar chamber without fan, at the ambient temperature for no longer than 60 minutes. C. albicans was recovered from the carriers immediately after drying and after contact time (1; 5, 10, 20, 40; 60 minutes). Results: The drying conditions applied reduced the recovery of C. albicans from 1.21 to 2.07 on a logarithmic decimal scale with respect to the test suspension with interfering substances. The difference between the recovery immediately after drying and the recovery after the tested contact times (up to 60 minutes) was insignificant. Conclusions: Achieving the number of C. albicans after the drying process, as provided for in PN-EN 16615, requires further improvement of the drying conditions or an increase of C. albicans suspension density before drying.

Crocus Sativus L

One possible method for the determination of DNA-polymorphism is the PCR-based AFLP (Amplified Fragment Length Polymorphism). This method had been succesfully introduced to the Department of Botany at University of Debrecen in 2000-2001 with the examination of hay saffron (Crocus sativus L.) and its allies. Hay saffron is grown as a spice for some thousand years producing the most expensive spice in the world. This plant is sterile, triploid reproduces only vegetatively with no fertile seeds. However its origin is unknown it exists only in cultivation and it is a mutated variety of another species or an artificial or natural hybrid. Usual methods for the systematic examination are restricted hence it seemed to be reasonable to apply molecular biological methods in its case. Results of this work include the introduction and many fold application of the method beside ensuring the consequences of science literature with determining the C. cartwrightianus to give the most similar genetical pattern to C. sativus.

Crocus Sativus L

From the methanolic extract of Crocus sativus petals nine known flavonoids have been isolated and identified, including glycosidic derivatives of quercetin and kaempferol as major compounds (1–2), and their methoxylated and acetylated derivatives. Additionally, LC-ESI-MS qualitative and LC-ESI-MS/MS quantitative studies of the major compounds of the methanolic extract were performed. The high content of glycosylated flavonoids could give value to C. sativus petals, which are a waste product in the production of the spice saffron.
