为改进传统重油蛋糕高糖高脂高热量等问题,以低筋面粉、鸡蛋为原料,先确定麦芽糖醇、甘露醇及海藻糖复合糖的添加比例,菊粉和奶油复合脂的添加比例,在此基础上,以复合糖添加量、复合脂添加量和烘焙时间为单因素,感官评定值为指标,利用Box-Behnken模型优化低糖低脂蛋糕的工艺流程。通过实验确定低糖低脂蛋糕的最佳工艺参数:每100 g鸡蛋中,复合糖添加量74 g(海藻糖∶甘露醇∶麦芽糖醇=1∶5∶9),复合脂添加量106 g(奶油∶菊粉=2∶1),烘烤时间21 min时,测得低糖低脂蛋糕的感官评定值为81.7±0.32分。该工艺制作的蛋糕不仅保留重油蛋糕口感厚重等特点,而且低糖低脂,蛋香浓郁不黏牙。本研究为低糖低脂食品的开发提供了理论依据和参考价值。 相似文献

Abstract The impacts of generic and branded advertising in the U.S. fresh potato, retail frozen potato, and potato chip markets are examined under exogenous and endogenous raw potato supply. The Almost Ideal Demand System is used to estimate the demand components. The general equilibrium elasticities derived from the complete model are used in a simulation analysis to assess the cross-commodity effects of incremental increases in advertising expenditures on equilibrium prices, quantities, revenues, and profits in each sector. The endogeneity of grower supply mitigate the impacts of advertising in the raw commodity sector and in the retail sectors. 相似文献

本研究以紫薯为原料制备紫薯饮料,确定紫薯饮料的护色工艺和液化工艺。得到最优护色工艺为:将紫薯片放入浓度0.5%的复合护色剂(Vc∶柠檬酸=3∶2)中,20℃下护色10 min;加2倍水打浆新鲜甘薯在70℃下,添加0.4%的α-淀粉酶液化60 min。此工艺条件下制作的紫薯饮料口感良好、营养丰富。 相似文献

灵芝是中国传统的珍贵药材,现代药理和临床研究证明:灵芝中含有多种生物活性物质,能够调节和增强人体免疫力,预防心脑血管疾病等。近年来,专家发现灵芝孢子粉的功效与作用比灵芝实体更为显著,随着食用菌深加工产业的发展,利用灵芝孢子粉和牛奶配制灵芝保健乳饮料对增加农产品的附加值有重大意义。基于此,以破壁灵芝孢子粉和牛奶为主要原料,采用单因素和正交试验结合感官评定的方法,确定出破壁灵芝乳饮料的最佳配方为破壁灵芝孢子粉0.2%、牛奶40.0%、绵白糖11.0%,复合稳定剂(黄原胶+CMC-Na)为1∶3,添加量为0.4%。 相似文献

Over five experiments, we demonstrate that physical cleansing (e.g., handwashing) can reduce consumers’ unhealthy eating in subsequent unrelated contexts, by decreasing their choice of vice food (e.g., chocolate cake) versus virtue food (e.g., fruit salad) and their preferred amount vice food for consumption. This effect generalizes over different food stimuli and different operationalizations of physical cleansing (i.e., actual cleansing, visualized cleansing, and vicarious cleansing). Further, an analogous effect occurs for consumers’ unethical choice in a non-food domain, thus increasing the generalizability of the cleansing effect. Finally, one potential mechanism of the effect based on the metaphorical associations between physical cleanliness and moral purity and between vice food and immoral consumption is suggested. 相似文献
