α-方便米饭加工工艺及产品品质研究 总被引:2,自引:1,他引:2
α-方便米饭是即食米饭中的研究重点,产品的品质评价因素主要有产品的外观、复水性、营养组成、贮运性质以及复水后的感官等,加工工艺是影响其产品品质的主要因素.目前α-方便米饭的生产工艺流程是:浸泡、蒸煮、离散、干燥、包装;单个工艺环节的最优选择为:1~2倍加水量下常温浸泡60~100min、常温常压下蒸煮30min、60~70℃热水离散和热风微波干燥,各个工艺环节之间的影响和及其工业化应用是未来研究的方向. 相似文献

研究了大米、玉米淀粉等原料对方便米线复水性的影响,同时比较了热风干燥、微波干燥、油炸干燥及微波和热风、热风和自然风、微波和自然风组合干燥6种干燥方法对方便米线复水性的影响.结果表明:原料对改善方便米线复水性的影响较小,利用不同的干燥方法所制取的方便米线的复水性和感官品质有明显差异,其中以热风-微波干燥较好,烘箱60℃下干燥20min,微波中火加热3min,水分含量为4.56%的方便米线复水时间仅为3min. 相似文献

实验对速煮绿豆加工工艺进行了优化,单因素实验表明浸泡时间、浸泡温度、蒸煮时间、蒸煮温度对复水性影响较大,且干燥方式对速煮绿豆的组织结构和形态保持上有明显影响;通过响应曲面回归分析,得到速煮绿豆优化加工工艺条件:在42℃0.5%NaHCO3浸泡液下浸泡4h,常压下100℃蒸煮40min,沥干,先恒温热风干燥30~40min,放置在密封容器24h,再微波干燥4~6min至水分含量为5%~7%,复水时间为5~12min。 相似文献

方便面和方便米线中酞酸酯的污染现状研究 总被引:1,自引:0,他引:1
目的:了解方便面和方便米线中酞酸酯(PAEs)的污染状况。方法:样品用无水甲醇超声提取,上清液经干燥脱水过0.45μm滤膜过滤,采用毛细管气相色谱技术分析。结果:在采集的56袋市售方便面、25袋方便米线中检测到的邻苯二甲酸二丁酯和邻苯二甲酸二(2-乙基己基)酯的含量分别为:方便面调味酱料:未检出~59.38mg/kg、未检出~172.15mg/kg;方便面面饼:未检出~9.28mg/kg、未检出~1.08mg/kg;方便米线调味酱料:未检出~16.52mg/kg、未检出~44.75mg/kg。结论:方便面和方便米线食品存在不同程度的PAEs污染。 相似文献

ABSTRACT: Powder for an instant shake-style beverage was created using partially defatted peanut flour (12% fat), granulated sugar, and nonfat dry milk (NFDM). The 3 main components, along with constant amounts of stabilizing gums and anti-caking silica, were mixed together and finely milled in a Super Wing Mill to further reduce the particle sizes. Drinks from each formula variation were prepared and analyzed for viscosity (digital viscometer), color (colorimeter), and separation rate. Each beverage was also analyzed by consumers to determine acceptability of flavor, mouth-feel, and color. Physical test results show that viscosity increased with increasing proportion of peanut flour in the formula, and viscosity decreased with increasing levels of sugar and NFDM. For each formula, the samples at refrigerated temperature (4 °C) were less viscous than those at ambient temperatures (23 to 25 °C). Color values show that the beverage powder color was mostly influenced by peanut flour percentage, becoming darker with increasing levels of peanut flour. Prepared beverage color was influenced by both NFDM and peanut flour percentage; lightness increased with increasing NFDM percentage and decreased with increasing peanut flour percentage. Separation rates were most affected by the proportion of NFDM in the formula; higher levels decreased the rate of separation. Refrigeration slowed the rate of separation in all samples. Response surface analysis of consumer test data showed that the most acceptable formulation for the peanut beverage included approximately equal amounts of peanut flour, sugar, and NFDM. 相似文献
