Spices are products made up of parts of plant species, with important nutritional value and many health benefits. The aim of this work was to evaluate adulterations in turmeric (Curcuma longa Linnaeus), ginger (Zingiber officinale Roscoe), nutmeg (Myristica fragrans Houttuyn), paprika (Capsicum annuum Linnaeus), black pepper (Piper nigrumLinnaeus) and colorific (mixture containing Bixa orellana with cornmeal). A total of 180 samples purchased in the municipalities of the state of São Paulo were analyzed. The investigation of the histological elements was performed by optical microscopy, the analysis of the dyes was carried out using paper chromatography and the quantification of the bixin was performance by high performance liquid chromatography. Of the 180 samples analyzed, 16.1% presented strange histological elements, classified as adulterations. Among the adulterated samples, none showed organic dye. Bixin analysis was carried out on colorific samples, ranging from 0.6 105.3 mg/100g, with an average of 18.9 mg/100g and standard deviation of 17.7 mg/100g, demonstrating the need to regulate the annatto extract concentration range added into the condiment. The evaluation demonstrated the necessity to monitor adulteration in spices, so that producers and merchants provide food with quality to the consumer. (AU)
