外文摘要：Mycotoxins widely contaminated the feed ingredients of shrimp, threatening the aquatic products, but their adverse effects on quality is less known. In this study, the adverse effects of T-2 toxin (T-2), aflatoxin B (AFB1), deoxynivalenol (DON), and ochratoxin (OTA) on the quality of Litopenaeus vannamei were investigated and compared. The results demonstrated that these four mycotoxins led the worse shrimp muscle color and tender texture, induced lipid peroxidation and pH change. Furthermore, four mycotoxins increased the K-value and total volatile basic nitrogen (TVB-N) to decrease the freshness. The median effective doses of T-2, DON, AFB1, and OTA on TVB-N of shrimp muscle were 4.86, 1.51, 0.26, and 0.20?mg/kg·bw, respectively. This study could provide useful information about the impacts and limited exposure dose of mycotoxins for quality preservation of shrimp. Practical applications: The shrimp quality is easy to deteriorate as it is most likely to be exposed to mycotoxins because of intensive farming practices using grain-based feeds, which were widely contaminated by mycotoxins. This study may provide a limited exposure dose of four prevailing mycotoxins aflatoxin B, deoxynivalenol, ochratoxin, and T-2 for preserving the minimal quality of shrimp, and also provide useful information for predicting the quality of shrimp from those highly mycotoxins-contaminated areas. ? 2019 Wiley Periodicals, Inc.
