Abstract

Saffron is a spice derived from the flowers of saffron which has been known in the world as an expensive spice. But huge amount of the petals are discarded as useless waste. The color of saffron petals is due to the compounds that called anthocyanins and flavonoids. Anthocyanins, are a class of natural compounds and Secondary metabolites in family of flavonoids. Indicators are the Colored organic compounds with complex structure which change in pH change their color. In this study, wastes of saffron of 32 different regions were collected from fields of saffron of Razavi Khorasan, Southern Khorasan and Kerman in November and then were transferred to the freezer with a temperature of-15 ° C. The amount of anthocyanins was determined in wastes of saffron then Rainfall and temperature in different regions between April and November 2014 were asked from Bureau of Meteorology. The SPSS 18 was used for statistical analysis. The results showed that there was a strong correlation between anthocyanins and amount of rain. Due to the abundant presence of anthocyanins in saffron waste, successful pursuit done to use these Natural pigments as an indicator. Results showed the color of anthocyanin pigments changes drastically with change in pH value, so it can be used as a natural and effective indicator to detect acid and base.
