膨化食品是以谷物、豆类、薯类、蔬菜等为主要原料,利用油炸、挤压、微波等膨化技术加工而成,使体积有明显增加的一种食品。在膨化食品生产中,原料选择决定产品口味;挤压设备的温度、水分、转速等参数的设定是影响产品外观和质量的关键;烘烤程度的判断决定最终产品的口感和保质期。 相似文献

挤压膨化技术在谷物加工中的应用 总被引:1,自引:0,他引:1
挤压膨化技术是一种现代的食品加工技术,在谷物类食品加工中具有广泛的应用。挤压膨化生产的食品有效的改善了口感,其营养丰富、简单快捷、便于食用、种类繁多,易于被广大消费者接受。挤压膨化技术解决了全麦粉由于含有丰富的酶类和大量的脂肪而不易保存的问题;提升了玉米和糙米的食用品质;提高了苦荞的适口性和食用品质;改善了大麦产品硬而缺乏弹性的问题,使大麦饮品利用率提高,饮料的沉淀率降低,赋予其浓郁的麦香味;改变了燕麦中膳食纤维的含量同时提高氨基酸的利用率。我们还简单介绍了挤压膨化技术在谷物加工中的工艺参数,以期对挤压膨化技术在谷物加工中更好地应用提供帮助。 相似文献

食品微波膨化技术研究进展 总被引:15,自引:0,他引:15
微波膨化技术作为一种新型食品生产技术熏正逐步在食品工业特别是休闲膨化小食品生产中得到广泛应用。微波膨化是微波能量到达物料深层转换成热能,将使物料深层水分迅速蒸发形成较高的内部蒸汽压力条件,迫使物料膨化。利用微波膨化技术加工食品能最大限度的保存食品原有的营养成分,加工时间短,膨化、干燥、杀菌工艺同时完成。本文主要介绍了微波膨化机理以及微波膨化技术在食品工业中的应用,并着重讨论了淀粉、蛋白质及其他添加剂等影响膨化效果的因素,同时对微波膨化技术的应用及发展作了展望。 相似文献

ABSTRACT: The puffing process was evaluated as an alternative to the steaming process for producing a biologically more active ginseng product, like red ginseng, from raw ginseng. A puffing treatment of dried raw ginseng roots induced an overall increase in crude saponin content. As puffing pressure increased, the content of ginsenoside Re, Rg1, Rb1, Rc, and Rb2 decreased, while ginsenoside Rg3 increased significantly as compared to raw ginseng. The content of ginsenoside Rg3 in puffed ginseng at a pressure of 490 kPa was similar to that of red ginseng. Cancer cell lines (HeLa, MCF-7, and HepG2) showed that antiproliferative effects of saponin extract of puffed ginseng increased with an increase in puffing pressure. Ginseng explosively puffed at 490 kPa had similar saponin constituents and antiproliferative effects as those of red ginseng. Practical Application: The puffing process could provide an alternative mean to produce functional ginseng products, along with a reduction in processing time as compared to traditional red ginseng processing by steam. 相似文献

Puffed quinoa can be used as ready-to-eat breakfast food or as an ingredient in snack formulations. In this study, puffed quinoa products with and without starch–chitosan coating were developed by gun, extrusion and microwave puffing at different process conditions (pressure, power, moisture content and energy consumption). Size, bulk density, colour, expansion index, water absorption and solubility, microstructure, mechanical and thermal properties, chemical composition and in vitro digestibility of organic matter and proteins of popped quinoa were assessed. Optimal process conditions for gun puffing were maximum 1.31 MPa after 780 s, 500 r.p.m. and 180 s for extrusion puffing and 1200 W for 60 s applying microwave puffing at 18–20% moisture contents. Gun and extrusion puffing yielded high-quality popped quinoa with a biological availability of organic matter between 84–88% and 79–90% for proteins. Extrusion and gun puffing are the most promising processes to prepare quinoa snacks. 相似文献
