In 2014, potato production in China amounted to 96 million tons, which was the highest in the world. As one of the most important nutritional foods in the world, potato is rich in starch, dietary fiber, vitamins, minerals, etc. Potatoes stand barren environment, drought, saline, and alkaline environment, and cold weather, with a short growing season. These features make them the best rain-fed crops suitable for production even when the annual rainfall is below 400 mm. In 2013, the Chinese Ministry of Agriculture suggested a potato staple food strategy using potatoes to make Chinese traditional staple foods such as steamed bread, noodles, etc. Our research group carried out a study on processing technology of potato staple food, especially fermented staple food. Some new processing technologies of potato staple food have been investigated and developed. The aim of this paper is to give an overview of the possible effects of adding potato flour in the dough and of the microstructure characteristics, technological parameters, total polyphenol content, and antioxidant activity of staple foods. We also systematically describe the processing technology of potato staple foods, which may be of great importance in promoting further expansion of the potato-processing industry and increasing the economic benefit of the companies. 相似文献

为了开发高含量马铃薯泥主食制品,本文探究了马铃薯泥含量为50%的马铃薯蒸馍的最优配方。以面团发酵特性、蒸馍感官评分、质构和色差等为指标,采用单因素和正交试验优化了马铃薯蒸馍配方。结果表明,随着谷朊粉含量增加,面团比容先增大后减小、宽高比先减小后增大,蒸馍的硬度、胶着度和咀嚼度先减小后增大,感官评分先增大后减小;随着棕榈油和酵母含量增加,面团比容增大、宽高比减小,蒸馍的硬度、胶着度和咀嚼度和感官评分增大。正交试验优化得到蒸馍的最佳配方为:马铃薯薯泥50%、面粉30%、谷朊粉5%、水7%、棕榈油4%、酵母3.5%、小苏打0.2%、盐0.3%,在此条件下得到的马铃薯蒸馍的感官评分为90.50分,蒸馍表面光滑、色泽亮丽均匀、外观挺立饱满并且具有马铃薯香气。本研究结果可为马铃薯主食化加工提供了理论基础。 相似文献

为提高马铃薯的利用率,丰富主食面包的种类,选取5个不同品种的马铃薯样品,蒸熟后制成马铃薯泥,按30%的比例添加到面包粉中制作面包。通过分析混合面团的粉质、拉伸特性及发酵性能,研究添加马铃薯泥对混合面团流变学特性的影响;通过对马铃薯泥面包进行感官评价和仪器分析,探索添加马铃薯泥对面包品质的影响。结果表明,添加马铃薯泥后,混合面团筋力减弱,加工性能略有下降,但具有良好的持气能力和产气能力,发酵性能良好;添加马铃薯泥后所制面包体积变大,且不易老化,其中加入5号马铃薯样品的面包感官评价总分最高,面包切片亮度高于对照样品,且粗气孔体积得到改善。综合考虑面包的感官和物理特性,添加5号马铃薯样品做出的面包品质最好。 相似文献

马铃薯全粉是新鲜马铃薯经去皮、切片、漂烫、护色等后脱水干燥制成的片状或粉末状产品,包含了除薯皮以外大部分马铃薯的营养物质,因此马铃薯全粉具有营养丰富、耐储的优点。作为马铃薯主粮化的原料,马铃薯全粉有助于改善和丰富我国居民膳食营养结构。近两年对马铃薯全粉的研究较多地集中在添加了马铃薯全粉制成的主食类或者其他相关产品的开发上。马铃薯全粉品质除了与马铃薯品种有关外还受到马铃薯全粉加工工艺的影响。本文将从马铃薯全粉生产过程中的前处理和干燥两个方面对马铃薯全粉品质的影响进行综述,以期为该领域的研究者提供理论参考。 相似文献

A study was made of the energy used in production of standard, white, sliced bread in three UK bakeries. The production chain studied covered all stages from receipt of flour at the bakery to arrival of bread at the retail outlet: primary energy use from all sources averaged 6.99 MJ kg-1 bread. In the complete production system for standard bread, including wheat growing, flour milling, baking and retailing, primary energy consumption was 14.8 MJ kg-1 bread and the energy subsidy (primary energy input: food energy output) for the system was 1.49. Primary energy used in home baking was dependent on the degree of loading of the oven and varied from 4.24–16.05 MJ kg-1 bread baked in a gas oven and from 10.84–54.76 MJ kg-1 bread baked in an electric oven. In comparison with mashed potato, roast beef and reheated canned corn, standard bread showed the lowest energy subsidy by a factor of at least five. The energy subsidy for standard bread production was only one-seventh of the figure which applies to the food system as a whole. The findings suggest that bread is the most energy efficient staple food product of an industrialised food production system. 相似文献

采用Mixolab通过对热-机械性能的分析研究了马铃薯生全粉的流变学特性。以11个马铃薯生全粉为实验材料,探讨Mixolab检测马铃薯生全粉流变学特性的重复性,结果显示:各样品的2次测试曲线的重合度高,全曲线的平均变异系数小于5%;通过对比B01~B10这10个不同样品检测结果,可以看到不同马铃薯栽培品种流变学特性存在较大的差异,具体表现在面团形成、面团稳定、淀粉糊化和回生各阶段检测指标上的差异;通过对比B06和B10两个采用不同研磨方式制备的样品,发现不同马铃薯生全粉制作的研磨工艺将极大的影响样品的吸水率、各粘度指标,但对马铃薯生全粉面团的弱化后稠度(Cs和C2)影响不大;通过对比马铃薯生全粉、雪花粉和标准面粉的热-机械能能曲线,发现雪花粉在马铃薯主食化产品开发中所起到的作用主要为填充剂。马铃薯生全粉具有良好的加工性能,流变学特性还可以通过食品添加剂进一步改善,制造出无需添加小麦面粉的纯马铃薯主食化产品馒头、面条和面包是可能的。 相似文献
