Closing Conclusion

Mycotoxin-potential producing mold such as A. flavus, A. niger, A. carbonarius, A. vesicolor, Eurotium, Fusarium and Penicillium capable to grow in herbal tea commodities

A. niger is the most frequent encountered mold Yeast contaminate the most of herbal tea as well

as coffee substitutes commodities Coffee substitutes have better mycological

quality than the herbal tea Aerobic mesophilic bacteria were found in all of

herbal tea and 83% in coffee substitutes with APC reach 1,0X106 cfu g-1

Page 12: Coffee and Tea

Suggestions Strict GMPs and hygienic practices should

be followed in every production level in order to minimize added contamination

Further and more extensive surveys are needed to observe the fungi profile and APC levels in herbal tea and coffee substitutes

The commodities should be tested for any pathogenic bacteria presence
