研究将统计过程控制(SPC)技术应用于水磨糯米粉微生物监测,绘制 X-R控制图,进行测量系统的分析。研究结果表明,未实施SPC技术时,部分批次糯米粉的菌落总数处于失控状态,而实施SPC技术后,糯米粉菌落总数一直处于稳态;SPC技术对糯米粉的生产环境起到很好的监控作用,以达到控制水磨糯米粉质量、降低微生物污染的最佳生产条件,最终实现生产过程的优化。实施统计过程控制,有利于企业及时发现并有效预防和控制生产过程中产生的微生物污染,把由微生物污染引发的潜在危害减至最小,对降低食品企业的生产成本、不断提高食品的质量具有重要意义。 相似文献

在生产面包及饼干专用粉的制粉过程中,粉路各系统不同出粉部位面粉的流变学特性呈现出明显的差异,这为粉流选择性混配提供了条件,使粉路在线配粉成为可能。研究表明,面包专用粉宜选择皮磨、渣磨、中路心磨及一部分前路心磨的面粉,饼干专用粉选择前路皮磨、前路渣磨及一部分心磨的面粉进行混配,由此能够配制出质量稳定的优质专用粉。 相似文献

Microbiology of wheat and flour milling in Australia 总被引:2,自引:0,他引:2
Berghofer LK Hocking AD Miskelly D Jansson E 《International journal of food microbiology》2003,85(1-2):137-149
A survey was undertaken to determine the microbiological status of Australian wheat and the distribution of microorganisms in the flour milling fractions and end products. A total of 650 milling process and end product samples was obtained from nine flour mills located in New South Wales (4), Queensland (2), Victoria (2) and Western Australia (1) during the 1997-1998 and 1998-1999 wheat seasons. Most frequent (modal) counts in wheat and flour were, respectively, as follows: aerobic mesophilic plate count, 10(5) and 10(2) colony forming units/gram (cfu/g); coliforms, 10 and 1 most probable number/gram (MPN/g); Bacillus spp., 10(4) and 10(2) cfu/g; B. cereus, 1 and 0.1 MPN/g; mesophilic aerobic spores, 10 and 1 cfu/g; aerobic thermophiles, both 10 cfu/g; yeasts, 10(3) and 10(2) cfu/g, and moulds, 10(3) and 10(2) cfu/g. Bacillus spp., coliforms, yeasts and moulds were the most frequently detected microorganisms throughout the survey. The most common moulds isolated were Aspergillus, Penicillium, Cladosporium and Eurotium spp. Environmental serovars of Salmonella were isolated from two samples. Escherichia coli and B. cereus were present at very low levels, a majority of positive samples being at the minimum level of detection (3 and 0.3 MPN/g, respectively). As wheat grain layers are separated, surface-adhering contaminants are concentrated in end product bran, wheat germ and pollard, which comprise the outer layers of the grain. Consequently, the inner endosperm fraction contains lower microbial counts, and flour is the cleanest end product of the milling process. Higher microbiological counts midstream in the milling process indicate that equipment contamination may contribute to microbiological contamination; however, the microbiological quality of incoming wheat has a strong influence on the ultimate quality of milling end products. 相似文献

不同粉路中的小麦粉及其淀粉性质测定 总被引:1,自引:0,他引:1
研究了1T下、3M下、1Sf小麦粉及其淀粉的性质,测定了其淀粉、蛋白质、灰分、水分以及直链淀粉的含量,并对淀粉的粒径分布、溶解度和膨润力以及淀粉糊的透明度、冻融稳定性等特性进行了分析。实验结果表明:在小麦胚乳结构中,越接近麦心的部位,淀粉和直链淀粉含量越高,水分和蛋白质含量越低,灰分的差异不大;淀粉颗粒的大小顺序为3M下>1Sf>1T下,粒径呈正态分布;小麦淀粉随温度的升高,溶解度增大,膨润力上升;小麦淀粉糊的透明度较高,冻融稳定性较差。 相似文献
