中文摘要：赭曲霉毒素A和黄曲霉毒素B1、B2、G1、G2,由葡萄园中的真菌产生并出现在用受污染的葡萄制成的产品中，如葡萄酒、葡萄干和未发酵的葡萄汁。这些毒素对生命有害。本研究用活性炭（AC）作OTC和黄曲霉毒素共同的吸附材料。研究表明，在所有试验中，根据炭的使用量，降低了霉菌毒素的浓度。OTA的吸附更好（96%），黄曲霉毒素B1和B2与吸附剂的亲和性更高（分别为95%和93%），黄曲霉毒素G1和B2分别减少了85%和80%。
外文摘要：Ochratoxin A (OTA) and aflatoxins B1, B2, G1 and G2, are produced by fungi which develop in the vineyard and they appear in products obtained from contaminated grapes, such as wine, raisins and must. These toxins are considered harmful to living beings. In this work activated carbon (AC) was used as adsorbent material for OTA and aflatoxins jointly. The adsorbent material tested was obtained from grape stalk. It was produced by carbonization and subsequent physical activation with steam. In order to perform the adsorption tests a sample of sulphited must was seeded with OTA and aflatoxins. Three samples of 200 ml were taken. Each one of them was contacted with 25, 50 and 100 mg of activated carbon, with continuous agitation to 300 K. In each test the concentration of mycotoxins at 30, 60 and 120 minutes was determined by extraction with immunoaffinity columns and subsequent quantification by HPLC. In all tests a concentration decrease of mycotoxins was obtained, according to the amount of coal used. The OTA had better adsorption (96%). The aflatoxins B1 and B2 appear to have higher affinity with the adsorbent (95% and 93% respectively). Aflatoxins G1 and G2 had 85% and 80% abatement respectively.
