小麦籽粒品质与馒头品质关系的研究 总被引:7,自引:1,他引:7
馒头是我国主要食品之一,消费量和面条相当,且南方的消费量还在逐年增长。21世纪以前,国内学者对制做馒头小麦粉品质的要求,馒头品质的评价方法,馒头品质与小麦品种籽粒品质的关系所能提供的研究资料十分有限。国外学者从70年代起就一直注意跟踪和研究这些问题。由于馒头的地域种类较多,不同人群对馒头的喜好不同,评价馒头品质指标的标准化程度不够,使不同结果之间有一定的差异,或完全相反。作者通过对小麦品种籽粒品质的分析,制作馒头面团发酵特性和油炸结果测定,馒头品质的评价认为:馒头对小麦粉品质的要求范围较大,从中筋到弱筋小麦品种都可以制作馒头;筋力愈高,面团的发酵时间愈长,馒头的弹性愈高;小麦品种小偃107制作的馒头色白,体积较大;小偃107的发酵面团在油炸过程中体积增加,有可能表现出吸油率低的特点。 相似文献

Fatty Acid Composition of Commercial Brassica and Sinapis Oils Oils of different brassica and sinapis varieties were analyzed in order to simplify the assessment of rapeseed oil and turnip rape oil. The results show that the fatty acid composition varies to a great extent, and therefore, rapeseed oil can no longer be defined on the basis of such a composition. 相似文献

Fatty Acid Composition of Rapeseed, Soybean, Sunflower and Peanut Oils Alterations in the mode of cultivation of oilseeds have brought forth considerable fluctuations in the composition of vegetable oils in the past decade. It is therefore desirable to report occasionally the new analytical figures on vegetable oils, whose source and past history are exactly known. 相似文献

Detection of Heat-Transfer Oils in Fats The use of heat-transfer oils in place of high pressure steam for heat transfer of fats from the discontinuous high temperature deodorization presumes analytical methods for the identification of traces of this oils in fats. In this paper two semi-quantitative rapid methods and one quantitative method applicable as an arbitrational analysis are described. A detection limit of ≤ 0.001% can be achieved. 相似文献

Detection of Small Quantities of Mineral Oils in Fats The thin-layer chromatographic detection of mineral oil traces in fats is described. Upto 5 mg of fat is chromatogrammed on silica gel G plates with heptan. With this, the saturated hydrocarbons travel upto approx. Rf 0.7 while the polar lipids (e. g. fatty acids, glycerides, sterols, unsaturated hydrocarbons) remain at the start. The limit of detection is 0.01%. The detection can also be carried out as spot-test. 相似文献
