摘要: 葡萄籽具有极高的营养价值和药用价值.为充分利用葡萄籽中的功能性成分,对葡萄籽的清洗、干燥、杀菌、冷冻和超微粉碎等工艺进行了研究.结果表明:葡萄籽超微粉的最佳工艺条件为:40 "C下干燥2h→ -20 "C下冷冻30min→以40 g/峙的比例加入微晶纤维素→混合后粉碎25min. 采用该工艺获得的葡萄籽超微粉的颗粒直径为2.5 -22.5μm ,平均直径为6.2μm ,而葡萄籽细胞的直径为15.0 -32.5μm ,平均为24.9μm ,说明细胞破壁率达到了100%.

Abstract:

Grape seeds are of very high nutritional and medicinal value. In order to make good use of the functional compounds in grape seeds , the processing technology of grape seeds including washing , drying , sterilizing , freezing and superfine grinding was investigated. An optimal processing procedure for superfine grinding was then determined, i. e. , dying the seeds at 40℃ for 2 h→freezing the seeds at - 20℃for 30 min→microcrystalline cellulose in a content of 40 g/kg→mixing and grinding the seeds for 25 min. Thus , superfine grinds of grape seeds with a diameter of 2. 5 - 22. 5 f.Lm and an average diameter of 6. 2μm were obtained. As the diameter of grape seed cell is 15. 0 - 32. 5μm and is 24.9μm on an average , it can be determined that the cell walls are totally broken.

Key words: grape seed, superfine grinding, cell-wall breaking ratio
