(一)芦荟凝胶作为新资源食品的申报 1998年原国家科委组织专家论证将芦荟产业定位为我国的新兴产业,并作为科技扶贫项目在许多农村推广种植.上世纪90年代受世界芦荟热浪的影响,我国也出现了芦荟开发高潮,全国芦荟种植面积近10万亩,芦荟应用以化妆品、食品为主.由于芦荟在我国一直没有被列入药食两用食物,我国芦荟产业陷入了低谷,种植逐年萎缩.芦荟食用市场准入成为制约我国芦荟产业发展的"瓶颈". 相似文献

由于芦荟这种植物具有抗菌消炎、抗氧化、抗肿瘤、抗辐射、增强免疫力,已经从原来单一的化妆品开发应用,走向了多领域、多样化的发展道路,特别是介入食品行业后,更是显示出了其旺盛的活力。芦荟饮料、芦荟酒类、芦荟奶系列产品、芦荟糖果类、芦荟调味品、芦荟糕点、芦荟功能食品等数十种产品使芦荟一举成为当前新兴食品的佼佼者,也让众多企业看到了芦荟的发展前景。本方案是以国内成熟技术为基础,采用我国东北地区优质大棚芦荟为原料,加以柠檬酸、蔗糖等辅料,经科学加工制成有益于人体健康的轻凉型安全天然饮料。产品外形独特,口味丰富,市场前景非常可观。 相似文献

ABSTRACT: To prevent the shrinkage of aloe vera slices during air drying, a method utilizing a shrink-proof layer was developed. The sample was configured of whole leaf aloe slices, where 1 side or both sides were covered with filter papers as shrink-proof layers. After air drying by varying the air temperature and the slice thickness, the drying characteristics, as well as several quality factors of the dried aloe vera leaf slices, were analyzed. In the simulation of the drying curves, the modified Page model showed the best fitness, representing a diffusion-controlled drying mechanism. Nonetheless, there was a trace of a constant-rate drying period in the samples dried by the method. Shrinkage was greatly reduced, and the rehydration ratios increased by approximately 50%. Scanning electron microscopic analysis revealed that the surface structure of original fibrous form was well sustained. FT-IR characteristics showed that the dried samples could sustain aloe polysaccharide acetylation. Furthermore, the functional properties of the dried slices including water holding capacity, swelling, and fat absorption capability were improved, and polysaccharide retention levels increased by 20% to 30%. Therefore, we concluded that application of shrink-proof layers on aloe slices provides a novel way to overcome the shrinkage problems commonly found in air drying, thereby improving their functional properties with less cost.
Practical Application: This research article demonstrates a novel air drying method using shrink-proof layers to prevent the shrinkage of aloe slices. We analyzed extensively the characteristics of shrinkage mechanism and physical properties of aloe flesh gels in this drying system. We concluded that this method can be a beneficial means to retain the functional properties of dried aloe, and a potential alternative to freeze drying, which is still costly. 相似文献
