Influência da forma de comercialização do chá de camomila (Camomilla recutita (L.) Raucher) sobre parâmetros microbiológicos contagem total e contagem de bolores e leveduras

Abstract

Tea is a drink very consumed in the world being used also as a herbal medicine., The objective of this study was to assess the level of overall contamination of chamomile tea (Camellia recutita (L) rouschert), marketed in different forms through general indicators of contamination total count of aerobic mesophilic and mold count and yeast. For this sold by street tea samples were acquired and also sold in supermarkets. Being evaluated the total count of aerobic mesophilic and the total count of molds and yeasts. It was observed that the total count of aerobic mesophilic ranged from 3,6.10^5 UFC/g to values exceeding 10^6 UFC/g, being greater in the bulk product sold by street. The same behavior was also observed for the yeast and mold count, where 2,10^4 UFC/g values were observed to 1,0.10^5 UFC/g, while the tea marketed by street presented mold and yeast counts between 5,3.10^6 UFC/g to 3,5.10^7 UFC/g which It may be related to failure to obtain the product. The results of this study showed that the teas sold in bulk without control of the stages of production and processing showed a degree of microbiological contamination higher than obtained in industrialized and commercialized in ways sachet.
