Abstract

The aim of this study was to investigate the effects of extrusion processing parameters-moisture content ( = 20 and 24%), feeding rate ( = 20 and 25 kg/h), and screw speed ( = 300, 390 and 480 RPM), on the content of deoxynivalenol (DON), 15-Acetyl Deoxynivalenol (15-AcDON), 3-Acetyl Deoxynivalenol (3-AcDON), HT-2 Toxin (HT-2), tentoxin (TEN) and alternariol monomethyl ether (AME), using a pilot single-screw extruder in whole-grain triticale flour. The temperature at the end plate of the extruder ranged between 97.6 and 141 °C, the absolute pressure was from 0.10 to 0.42 MPa, the mean retention time of material in the barrel was between 16 and 35 s, and the specific energy consumption was from 91.5 to 186.6 Wh/kg. According to the standard score, the optimum parameters for the reduction of the content of analysed mycotoxins were = 24 g/100 g, = 25 kg/h, = 480 RPM, with a reduction of 3.80, 60.7, 61.5, 86.5, 47.7, and 55.9% for DON, 3-AcDON, 15-AcDON, HT-2, TEN, and AME, respectively. Under these conditions, the bulk density, pellet hardness, water absorption index, and water solubility index of the pellet were 0.352 g/mL, 13.7 kg, 8.96 g/g, and 14.9 g/100 g, respectively.

摘要

本研究的目的是使用中试单螺杆挤出机，研究挤出加工参数——水分含量（20%和24%）、进料速率（20和25千克/小时）以及螺杆转速（300、390和480转/分钟）对全谷物小黑麦粉中脱氧雪腐镰刀菌烯醇（DON）、15 - 乙酰脱氧雪腐镰刀菌烯醇（15 - AcDON）、3 - 乙酰脱氧雪腐镰刀菌烯醇（3 - AcDON）、HT - 2毒素（HT - 2）、细交链孢菌酮酸（TEN）和交链孢酚单甲醚（AME）含量的影响。挤出机端板处的温度在97.6至141℃之间，绝对压力为0.10至0.42兆帕，物料在料筒中的平均停留时间为16至35秒，比能量消耗为91.5至186.6瓦时/千克。根据标准评分，降低所分析霉菌毒素含量的最佳参数为水分含量24克/100克、进料速率25千克/小时、螺杆转速480转/分钟，DON、3 - AcDON、15 - AcDON、HT - 2、TEN和AME的含量分别降低3.80%、60.7%、61.5%、86.5%、4 .77%和%55.9。在这些条件下，颗粒的堆积密度、颗粒硬度、吸水指数和水溶性指数分别为0.352克/毫升、13.7千克、8.96克/克和14.9克/100克。
