胡萝卜微粉物理特性和营养成分的影响因素（Influence Factors on Physical Properties and Nutrient Component for Carrot Micro-powder）
胡萝卜 微粉加工 物理特性 营养成分
font style='font-size:12px;'>
2009/11/24
胡萝卜微粉制备中，影响微粉物理特性及营养成分的试验分析表明：热风和微波干燥获得的胡萝卜微粉容积密度大，冷冻干燥的胡萝卜微粉容积密度小。微波干燥获得的胡萝卜微粉溶水性好，其次是冷冻干燥；胡萝卜生粉比熟粉溶水性好。胡萝卜生粉的氨基酸质量比高于熟粉和冻融粉；真空冷冻干燥生胡萝卜，粉碎粒径小于240目时，氨基酸质量比高。经过冻融处理的胡萝卜微粉VC质量比高于其生粉和熟粉；冷冻干燥的胡萝卜微粉VC质量比高。...
胡萝卜过热蒸汽膨化干燥工艺优化（Optimization of Super Heated Stream Puffing Drying Technology for Carrot）
胡萝卜 过热蒸汽膨化 干燥 工艺优化
font style='font-size:12px;'>
2010/2/26
以胡萝卜为原料，采用三因素二次正交旋转组合设计，研究了预脱水的胡萝卜含水率、过热蒸汽温度和滞留时间对膨化胡萝卜比容以及产品复水率的影响。这3个因素的影响均达到显著水平，过长的滞留时间可增加比容，但极大降低产品复水率。优化的过热蒸汽膨化工艺条件为：预脱水的胡萝卜含水率23%，过热蒸汽温度150℃，滞留时间50s。过热蒸汽膨化干燥的胡萝卜收缩较小、复水率高、硬度适中、品质好。过热蒸汽膨化干燥胡萝卜较热...
