对小麦的籽粒品质、面粉品质、面团流变学特性、淀粉特性及蛋白质数量和蛋白质质量对馒头质量的影响做综合概述。馒头质量受小麦品质的综合性状所控制,而蛋白质数量和质量起主要作用。由于南北方地域不同,人们食用的口味不同,相对比较南方馒头要求面筋强度偏弱,北方馒头要求面筋强度偏强一些。蛋白质含量和面筋强度为中等水平的小麦适合于制作馒头。 相似文献

馒头是我国居民的传统主食之一。随着馒头机械化生产和市场化销售比例增加,馒头产业得到较快发展。在工业化馒头制作条件下,小麦品种特性及其面粉的馒头制作适宜性,尤其是面粉质量的稳定性,显著影响馒头的产品质量、消费体验及工业化生产的经济效益。选用豫西南地区生产上种植面积大、代表性较强的小麦品种为原料,分析其小麦粉品种的理化特性,研究馒头制作的适宜性及其小麦粉品种质量和馒头特性之间的关系。结果表明,豫西南小麦粉湿面筋含量较高,但面筋指数还有待改进;优质小麦占比有待提高;小麦粉色泽红绿值(a*值)、黄蓝值(b*值)、面筋指数、粉质参数的面团软化度、拉伸参数的拉伸面积及吹泡参数的面团延展性,是评价馒头粉质量的重要参考指标。小麦品种郑麦119、平麦998、陕道198、郑麦1342、郑麦1860比较适合制作馒头。 相似文献

在上海的一些华联超市和联华超市,主食专柜都在销售同一个公司生产的三种馒头,这些看起来自白香软的小麦馒头、淡黄诱人的玉米面馒头,却是靠着色剂染色生产出来……随着央视的曝光,人们谈馒头色变的背后,纷纷关注身边的食品安全问题,更多选择了在家中做面食。厨房电器中,将由谁来担当此重任? 相似文献

In recent years, substantial consideration within the food industry has been aimed at the development of food‐grade nanoemulsions (NE) as promising systems for encapsulating, stabilizing, and delivering bioactive compounds. Although numerous studies have revealed the critical potential of NE, there are still several challenges to overcome them. These include the extensive amounts of synthetic emulsifiers needed for NE formulation, which can potentially be toxic for human health. The interest in safety, and natural emulsifiers have stimulated food manufacturers to develop "label‐friendly" formulations by replacing synthetic emulsifiers with natural alternatives. This review represents a critical and comprehensive summary of the application of natural emulsifiers as potential substitutes for synthetic emulsifiers in NE production, with particular emphasis on the newly identified natural emulsifiers. Some recent reports showed the excellent emulsifying properties of various natural emulsifier extracted from natural resources, to produce NE, and therefore, might be generalized for further industrial applications. Future trends are encouraged to identify novel natural emulsifiers from industrial food by‐products that may demonstrate highly effective emulsifiers. 相似文献

Functionality of different emulsifiers on the performance of breadmaking and wheat bread quality 总被引:1,自引:0,他引:1
Emulsifiers are widely used in bakeries as dough strengtheners and crumb softeners, but there is a great diversity of compounds with emulsifier action. The objective of this study was to analyze the influence of emulsifiers with different functionalities on the rheological characteristics of wheat dough, as well as their effect in the final bread parameters, including behavior during aging. All the emulsifiers tested increased dough stability, although the extent of this effect was concentration-dependent. The presence of emulsifier retarded dough proofing; in consequence, longer proofing times would be required when emulsifiers are used. In fact, the positive effects of emulsifiers on bread volume were only observed with long proofing times, and that also became evident when crumb hardness was analyzed. Sodium stearoyl lactylate, sucrose ester, lecithin and enriched lecithin were the emulsifiers with the greatst crumb softening effects at extended proofing times. However, when the objective is a hardening delay during storage, the emulsifiers of choice are monoglyceride and lecithin enriched in lysophospholipids. This study reveals the importance of the proofing period to the functionality of the emulsifiers when used for breadmaking performance. 相似文献

A study was carried out to compare the fatty acid composition and thermal profiles of mono- and diacylglycerols of six commercial emulsifiers, coded as E1, E2, E3, E4, E5, and E6, purchased from different manufacturers with those of the same derived from lard. The lipid extraction from the commercial emulsifiers was done using the Soxhlet method and the isolation of individual mono- and diacylglycerols was carried out using a column chromatographic method. The isolated partial acylglycerols of lard and individual emulsifiers were subjected to fatty acid analysis by gas chromatography and thermal analysis by differential scanning calorimetry. A clear distinction between lard-based emulsifier and the commercial emulsifiers was achieved by the application of principal components analysis to the fatty acid data. According to thermal analysis, mono- and diacylglycerols of lard displayed significant differences from those of commercial mono- and diacylglycerols with respect to the thermal transitions in the cooling curves. This study concluded that partial acylglycerols of none of the commercial emulsifiers employed in this study displayed similarity to those of lard-based emulsifiers. 相似文献
