The investigation of aroma compounds of the essential oils of dried fruits of black pepper (Piper nigrum) and black and white "Ashanti pepper" (Piper guineense) from Cameroon by means of solid-phase microextraction (SPME) was carried out for the first time to identify the odorous target components responsible for the characteristic odor of these valuable spices and food flavoring products. By m...

INTRODUCTION Spices are ingredients to confer improved taste to foods. As they are derived from plants, they have the potential for inducing allergic reactions. There is a lack of studies to accurately determine the rate of pepper allergy in children. Allergic reactions to pepper in children are rare. This case illustrates such a reaction. METHODS Patient is a 17-month-old boy with mild eczem...

It was found out that spices straight from the package are not sterile. The only way to receive sterile spices is to use radiation technology which means to irradiate spices with ionizing radiation. However, this method is quite expensive and raises great resistance of public. And this is the reason why we are interested in implementing plasma technology. The first step of the research was to c...

The present study was carried out to investigate the aflatoxigenic and ochratoxigenic fungi and their mycotoxins from 194 samples of 5 types of spices (black pepper, turmeric, fennel, green cardamom and mace). Ochratoxin A producing A. niger and aflatoxin producing A. flavus were the most dominant species present in all types of spice. 52% of A. flavus and 44% of A. parasiticus from black peppe...

Nine different Indian spices (red chilli, black pepper, turmeric, coriander, cumin, fennel, caraway, fenugreek, and dry ginger) commonly cultivated and highly used in India were analysed for natural occurrence of toxigenic mycoflora and aflatoxins (AFs), ochratoxin A (OTA), and citrinin (CTN) contamination. Aspergillus flavus and Aspergillus niger were the most dominant species isolated from al...
