During saffron (Crocus sativus) spice production, large amounts of floral biowaste are generated. It was the aim of this study to develop a value-added product from saffron floral biowaste to be used as a natural cosmetic ingredient. HPLC-PDA-MS analysis of saffron flower extracts revealed the presence of flavonols with the highest amounts in the acetone extract. Kaempferol-3-O-sophoroside was ...

The separation possibility of stigma from the other parts of saffron flower using its aerodynamic properties was investigated and a vertical air column was designed on the basis of the obtained results. Terminal velocities of three parts of saffron flower, including petal, stigma and anther within four days after harvest were studied. Significant difference between terminal velocity of stigma (...

To develop saffron planting in Urmia, West Azerbaijan, Iran, a split-split plot experiment based on CRBD was carried out in the Urmia University's research farm for two years (2013-14). Nanofertilizers (Fe, P, K and nofertilizer (control)) as main plots, saffron ecotypes (Mashhad, Torbat-Heydarieh, Torbat-jam, Gonabad, Ghaen and Birjand) as subplots and maternal corm weight (6, 8, 10 and 12 g) ...

The effects of chemical and organic fertilizers on saffron (Crocus sativus) were studied in a field experiment using a complete randomized block design with three replications at ferdowsi university of Mashhad. Fertilizers applied were N, P, K, NP, NK, PK, NPK, cow, sheep and chicken manure. The amount of chemical fertilizer applied were 50, 30, 30, 48, 48, 36, 66 kg/ha for N, P, K, NP, NK, PK,...

There is increasing evidence that consumption of saffron, a spice derived from the flower of the Crocus savitus plant, has various therapeutic effects, including protection of the central nervous system. These beneficial effects have been widely attributed to the strong antioxidant properties of saffron and its key constituents, although data showing that these antioxidative properties are pote...

the separation of saffron stigmas from fresh flowers is the most important and the most difficult stage of saffron harvesting. saffron production costs are high because this harvesting stage is done by hand and is very time-consuming. one way of preserving the saffron flower is to dry it. the separating of the stigma from dried saffron flowers can then be done at an appropriate time. this study...

in order to study the effect of irrigation intervals and intecropped marjoram (origanum vulgare) (as a shading crop for reducing the possible effects of soil warming due to climate change) on the growth and yield of saffron (crocus sativus), a field experiment was conducted as split-plot based on randomized complete block design with three replications, during 2008 and 2009 at the agricultural ...

in order to investigate the effects of high corm planting density and applying manure on flower and corm yields of saffron (crocus sativus l.), a field experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran, during growing season of 2010-2011. a completely randomized block design with three replications and 20 treatments was used. the experime...

Saffron (Crocus sativus L.) is a light purple flower with reddish colored stigma. It is one of the most expensive spices with a range of quality in its color and aroma. A few key countries involved in saffron commercialization are Spain, Iran, Greece, Morocco, India and China. The main chemical constituents found in saffron are safranal, picrocrocin, crocetin and its glycoside, crocins. These c...

saffron is the most important iranian non oil export. improper conditions of saffron flower storage increases microbial contamination and decreases saffron quality. this study was done for prolonging the shelf life of saffron flower in modified atmosphere packaging and subsequent to producing a new method for exporting the fresh saffron flower as cut flower. saffron flowers were packed in a pol...
