矿物质强化面包酵母饲料的开发

酵母（Ｙｅａｓｔ）系１６８３年由荷兰的林文虎克氏所确认，它属于真菌类的真核生物。当今，酵母已广泛用于饮料发酵、食品发酵和制作维生素、酶制剂、蛋白质（人、动物）、酒精、甘油、甘露醇及有机酸等。当然，某些酵母也会引起人和动物疾病。所以，在工业使用上，均有...

磁场下电解质流体对马铃薯片品质的影响

为提升马铃薯片品质,采用含不同质量分数氯化钙、葡萄糖酸锌、抗坏血酸的溶液流体处理垂直磁场下的马铃薯片,结果表明,马铃薯片置于磁感应强度1 500 Gs环境下利于溶质的渗透,流速为0.05 m/s处理的马铃薯片品质改善显著,若电解质流体流速过高则会干扰溶质的渗透。空白样即未施加磁场的情况下,产品品质均无任何改善。该技术可实现对马铃薯片的品质提升,包括微量元素的营养强化和保脆处理,且弱电解质即抗坏血酸在流场中也受垂直磁场的影响并富集于马铃薯片组织表面从而使其具有抑制褐变的效果。

Co-intensification of gold leaching with heavy metals and hydrogen peroxide

Co-intensification was researched to accelerate gold leaching with regards to its electrochemical nature by using anodic intensifiers of heavy metal ions (Pb2+,Bi3+,Tl+,Hg2+ and Ag+) on the basis of hydrogen peroxide assistant leaching on three different types of materials which were classified as a refractory sulphide gold concentrate,an easily leachable sulphide gold concentrate,and a low grade oxide gold ore according to their leaching characteristics.The results showed that,favorable co-intensification effects on the three materials were obtained and leaching time of gold was effectively shortened to no longer than 12 h from 16 to 24 h for hydrogen peroxide assistant leaching.For the five tested heavy metal ions,Bi3+and Tl+ presented co-intensifying effect on all the three materials,and Hg2+ caused co-intensifying effect on both refractory and easily leachable sulphide gold concentrates,and Pb2+ and Ag+ only had co-intensifying effect on the easily leachable sulphide gold concentrate.

食品营养强化剂预混料的动态吸附制备方法

研究以微孔淀粉为吸附包埋及粘附包埋剂,采用动态吸附包埋以及二次粘附包埋干燥的方法,对几种常用矿物质(硫酸亚铁、硫酸锌、硫酸铜、硫酸锰)进行了吸附、粘附包埋试验。研究探讨了动态吸附包埋、粘附包埋、干燥的工艺和设备,同时对制备的矿物质营养强化剂预混料的包埋效果进行了评价。研究结果表明,研究制备的营养强化剂预混料有效降低了金属离子对维生素A、C的降解作用。
