Three formulas of cookies prepared from 50:45:5 (I), 50:40:10 (II) and 50:35:15% (III) wheat flour, broken rice flour, and defatted soy flour, respectively, baked in a microwave oven (2450 MHz) for 240 sec, were rated as the best of six formulas for flavor and texture by a trained panel. Cookies of formulas I and II were preferred over formula III by a consumer-type panel. Cookies of all three formulas showed no significant differences in nitrogen balance, apparent biological protein value and apparent net protein utilization. Apparent protein digestibility and protein efficiency ratio were significantly higher in formulas II and III than in formula I. 相似文献

Partitioning and Absolute Flavor Threshold Interactions of Aliphatic Food Packaging Solvent Homologs in High-Fat Cookies 总被引:1,自引:0,他引:1
Partition coefficients (Kp) and absolute flavor thresholds were determined in high-fat containing cookies for 9 alipahatic homologs of increasing polarity: three n-alkanes (hexane, heptane, octane), three ketones (acetone, 2-butanone, 2-pentanone) and three alcohols (ethanol, n-propanol, n-butanol). Kp increased with carbon chain length in each homologous series. Absolute thresholds of the alkanes increased with carbon chain length but decreased in the ketone and alcohol homologs. Mixtures of homologs at subthreshold and threshold concentrations gave additive interactions while a heterogeneous mixture behaved independently. Calculation of residual concentrations in a cookie package that could produce off-flavor gave different values for mixtures vs. individual solvents. 相似文献

为开发富含膳食纤维的低温鱼肉香肠,以鹰嘴豆粉、草鱼肉为实验材料,设计单因素试验,研究不同添加量鹰嘴豆粉对鱼肉香肠质构、色泽、凝胶强度、持水率及蒸煮损失率等品质特性的影响。结果表明:添加鹰嘴豆粉对鱼肉香肠的质构特性、色泽、凝胶强度及保水性均产生影响,鹰嘴豆粉添加量0%~10%时,鱼肉香肠的硬度、咀嚼性、凝胶强度和持水率出现先上升后下降趋势,其中鹰嘴豆粉添加量6%时达到最大值,而蒸煮损失率、亮度值和白度显著减小(P<0.05),鹰嘴豆粉添加量大于6%时蒸煮损失率下降趋于平缓。综上可知,鹰嘴豆粉可以影响低温鱼肉香肠食用品质,在鹰嘴豆粉添加量为6%时,各项指标均趋于理想范围,因此鹰嘴豆粉的最佳添加量为6%。鱼肉香肠中添加适量鹰嘴豆粉不仅能改善香肠品质,还能赋予鱼肉香肠鹰嘴豆特有风味。 相似文献

本文以面粉、豆纤维粉、橙皮糖为主要原料,通过单因素实验,研究豆纤维粉添加量、橙皮糖添加量、糖油质量比(黄油与糖粉的比值)对豆纤维橙味曲奇饼干的感官评分和硬度的影响。按Box-Behnken法设计试验方案,运用响应面分析法建立多元二次非线性回归方程,以感官评分为指标,优化豆纤维橙味曲奇饼干配方,确定豆纤维粉添加量、橙皮糖添加量、糖油质量比。结果表明,豆纤维橙味曲奇饼干的最佳添加量为:豆纤维粉添加量为26%(以面粉与豆纤维粉的总量为基准)、橙皮糖添加量为16%、糖油质量比为2:1。在此条件下的曲奇饼干色泽均匀,硬度、甜度适中,并具有橙皮特有的清香以及豆纤维食品的独特口感,其感官评分为(87.3±1.1)分,与预测值87.7分接近,偏差为0.4%,说明该模型下确定的产品配方对实际生产具有较好的指导和应用价值。 相似文献

蒸汽爆破甘薯渣粉对小麦粉粉质及饼干品质特性的影响 总被引:1,自引:0,他引:1
研究蒸汽爆破甘薯渣粉对小麦粉粉质及混合粉制作饼干品质特性的影响。将蒸汽爆破甘薯渣粉添加到小麦粉中,测定不同比例蒸汽爆破甘薯渣粉与小麦粉混合后的沉淀指数、糊化特性、粉质特性以及混合粉饼干质构性质。结果表明:小麦粉中添加不同量的蒸汽爆破甘薯渣粉后,小麦混合粉的沉淀指数、峰值黏度、低谷黏度、稀懈值、最终黏度和反弹值均降低;蒸汽爆破甘薯渣粉添加到小麦粉中,面筋蛋白被稀释,吸水能力随可溶性膳食纤维质量分数的增加而增加,而面团的形成时间和稳定时间缩短,弱化度升高,粉质质量指数降低;混合粉焙烤出的饼干质构特性发生变化。根据饼干的质构特性和感官评定结果,在低筋面粉中添加质量分数6%的蒸汽爆破甘薯渣粉时,混合粉制作的饼干品质最佳。 相似文献

Flow properties of aqueous chickpea protein dispersions were investigated. The dispersions had Newtonian flow behavior at concentrations up to 4%. Flow behavior became progressively less Newtonian as concentration increased above 4%. The apparent viscosity of the dispersions was pH and concentration dependent, being higher at the protein's most soluble pHs (pH 2 and 9) and lower at the isoelectric point (pH 4–5). Within the investigated temperatures (15, 25, 35 and 55°C), power law constants were unchanged up to 35°C but the flow behavior became non-Newtonian at 55°C. Denaturation by urea and sodium dodecyl sulphate (SDS) increased the consistency index (m), casson yield stress and apparent viscosities, and the flow became more pseudoplastic with a decrease in the flow index (n). 相似文献
