摘 要胡萝卜在加工成汁的过程中会产生大量的废渣，而这些胡萝卜渣中含有大量的营养物质，可以通过干燥工艺得到类胡萝卜素含量较高的胡萝卜渣微粉，把它加入到巧克力中可制备能够迅速恢复体力的能量棒。采纳真空干燥和热风干燥及联合干燥对胡萝卜渣干燥过程中含水量及类胡萝卜素含量动态变化规律进行讨论与比较。先采纳热风 85℃干燥 45min 后再真空 75℃干燥，当胡萝卜渣含水量达到 8%时，干燥时间最短，为 150min，类胡萝卜素的损失率最少，仅为 3.5%。热风-真空联合干燥技术能在较短的干燥时间内较大程度地保存胡萝卜渣中的类胡萝卜素，为较佳的胡萝卜渣干燥的最佳工艺。所得到的能量棒是由巧克力浓浆和胡萝卜渣微粉组成的，通过感官评定得到当胡萝卜渣微粉的添加量为巧克力浆的 20%时，所得的能量棒口感最好，并有一定的饱腹效果。关键词：胡萝卜渣；类胡萝素；水分；干燥；能量棒Preparation of carrot pomace powder and energy barsAbstractCarrots processed into juice, the process will produce large amounts of waste, these slag contains large amounts of nutritional quality, higher drying process, the carotenoid content of carrots with higher residue, add it to the chocolate has a certain functional energy bars. vacuum drying and hot air drying and drying the moisture content during the drying process of carrot residue and carotenoid dynamic variation.85℃of the first hot air drying 45min 75℃and then vacuum dried carrot residue to 8% moisture content, drying time, 150min, the least loss of carotenoids, only 3.5%.The hot air - vacuum drying in a shorter drying time save a large extent on the carotenoids in the carrot pomace, carrot residue for better drying process.Energy bars, chocolate thick paste and carrot pomace powder by sensory evaluation When carrots slag powder and chocolate accounted for 20%, taste the best.Keywords: carrot residue, carotenoids, water content, dry, energy bars目 录摘 要..........................................................................
