一些热敏性物质（如林化产品），在用常规喷雾干燥技术处理时，由于温度较高对其品质影响非常严重，所以研究者开始将喷雾与冷冻两种技术融合起来进行研究。国外，美国、瑞士、德国、新西兰等国家对喷雾冷冻干燥技术的研究是采用液氮或者干冰等低温流体来制备低温低湿的空气，虽然喷雾冷冻干燥工艺可以实现，但是，工业化开发、设备的高制作要求都遇到了困难，仍旧需要深入研究。国内，此项技术处于空白状态。
杨树是我国重要的造林绿化和工业用材树种，人工林总面积居世界第一，在改善生态环境、解决木材供需矛盾、发展地方经济、增加农民收入等方面发挥着越来越重要的作用。长期以来，杨树主要被利用的部分是木材，在木材加工过程中产生的树皮剩余量很大，大多作为废弃物堆积在木材加工厂周围，任其腐烂，污染环境，必须寻找一条杨树皮废弃资源开发利用的新途径。
松树适应和生存能力极强，在长期的自然选择过程中，形成了一套完善的防御体系，蕴藏着结构新颖、变化多样和具有显著生物活性的化合物，它们的经济价值和药用潜力越来越受到人们的重视。我国是松科植物属种最多的国家，有10属113种，种数占整个松科植物的1/2，资源十分丰富。以松树抚育及采伐的松针剩余物为原料，通过精深加工和高效利用，开发食品级、医药级和高附加值的林源产品，可广泛应用于天然药物、保健食品、食品添...
