국산 및 중국산 유통 건고추에 대한 aflatoxin B1, ochratoxin A 및 곰팡이 수에 대한 모니터링

Abstract

To research the contamination status of ochratoxin A, aflatoxin B1, and Howard Mold Counting of a red pepper, the test was performed on 80 kinds of a red pepper yielded and dehydrated with its stalk between 2006 to 2007. Aflatoxin B1 was detected in 2 samples of total 40 peppers produced in Korea, in the range of 2.5～4.3 ㎍/㎏. Six samples of 40 peppers produced in China have contained 0.2～15.3 ㎍/㎏ of aflatoxin B1. In the case of ochratoxin A, peppers of 4 districts in Korea have contained in the range of 2.0～3.9 ㎍/㎏. But on the other, 2.8～13.9 ㎍/㎏ of ochratoxin A was detected in peppers of distric's name - Ik Do from China, and 4.5～13.2 ㎍/㎏ was detected in peppers of distric's name - Cheong Do from china. In addition, It was researched that peppers from china have counted 0～20% of molds and it was little more than those of korea 0～15% by Howard Mold Counting assay. And quality of peppers can be classified into 3 levels by dehydration condition. The data shows that the lower quality was the more mols % they have got, In some case, Chinese peppers of 3rd level was counted 2 times higher than those of Korea. In research of aflatoxin B1 detection in each part of peppers divided into 3-seeds, pulp, stalk, It wasn't detected in pulp but in stalk, It was detected 22.2 ㎍/㎏ in Korean peppers and 47.0 ㎍/㎏ in Chinese peppers. Also ochratoxin A was not detected in pulp, but in stalk, about 28 ㎍/㎏ of ochratoxin A was dected in Korean peppers and in chinese peppers it was about 29 ㎍/㎏. And in Molds %, there were no differences between producing area and each parts. In conclusion, It is needed to use pure pulp excepting stalks and seeds in process of producing powder peppers for the reduction of these toxin such as aflatoxin B1, ohcratoxin A and molds number.
