摘  要：
为了解决葡萄籽在超微粉过程中的结块问题,对影响葡萄籽超微粉结块的葡萄籽水分含量、脂肪含量、葡萄籽粉碎时间、抗结剂的选择等因素进行了研究。结果表明,葡萄籽水分含量大于50.0 mg/g时,结块量增加明显;脂肪含量为116 mg/g时结块较少,脂肪含量越高越易结块;葡萄籽粉碎时间超过25 min时,结块量增多,延长到55 min后趋于稳定;储藏时间对葡萄籽超微粉结块的影响不大;使用抗结剂可减少葡萄籽超微粉的结块,在微晶纤维素、硬脂酸钙、二氧化硅等几种抗结剂中,微晶纤维素的抗结块能力最好,以30~35 g/kg微晶纤维素对结块抑制作用最为显著。因此在葡萄籽加工中,选择脂肪含量低的葡萄籽,并干燥到水分含量恒定,粉碎时添加30~35 g/kg微晶纤维素,并控制粉碎时间在25 min以内,可有效减少超微粉结块。

摘  要：
In order to solve the agglomeration of the grape seeds ultrafine-powder,the factors which influenced the agglomeration of grape seeds ultrafine-powder,such as different moisture content of grape seeds,different fat content of grape seeds,different smashing of grape seeds,and the choice of anti-agglomeration reagent were studied.The result indicated when the moisture content was bigger than 50.0 mg/g,more agglomeration increased obviously;when fat content was bigger than 116 mg/g,there was little agglomeration;when smashing time surpassed 25 min,more agglomeration increased,and tended to keep stable after 55 min time;with the time of storage extended,the agglomeration of grape seeds ultrafine-powder did not increase;the anti-agglomeration reagent coule be used to reduce the agglomeration of grape seeds ultrafine powder in the Microcrystalline Cellulose,Calcium Stearate,Silicon Dioxide,among which the Microcrystalline Cellulose was better;the Microcrystalline Cellulose between 30-35 g/kg showed best inhibition.So,in the processing of the grape seeds,it's good to choose low fat content,drying moisture content to invariableness,and when crushed,add the Microcrystall the Cellulose between 30-35 g/kg,and control the time of comminution of grape seeds in less than 25 min.
