In this study, amaranth flour was used as an ingredient to prepare gluten-free cookies. The production process and attributes of amaranth cookies were characterised, and the potential use of amaranth flour as a functional ingredient was analysed. Cookies exhibited a non-uniform reddish brown colour and a cookie factor ratio of 4.5 ± 0.6. Storage studies indicated that after 3 weeks at room temperature cookies presented slight variations in the texture. Simulated gastrointestinal digestion of this product was able to release peptides capable of exerting potential antithrombotic and antihypertensive activities, IC50 values of 0.22 ± 0.04 and 0.23 ± 0.03 mg mL−1 protein, respectively. This work demonstrates for the first time that food made with amaranth flour exerts potential antithrombotic and antihypertensive activity. In conclusion, these amaranth cookies could be an alternative way of incorporating potentially health beneficial products for people who choose a conscious diet, including coeliac or vegan consumers. 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

Abstract: Effect of radio frequency (RF) postdrying of partially baked cookies on acrylamide content, texture, and color of the final product was investigated in this study. Control cookies were prepared by baking in a conventional oven at 205 °C for 11 min. Cookies partially baked for 8 and 9 min were postdried in a 27.12 MHz RF tunnel oven until attainment of the moisture content of control cookies. Internal temperature of cookies was monitored during the experiments to better explain the results. Cookies were analyzed for acrylamide content using a liquid chromatography‐mass spectrometry (LC‐MS) method. Texture measurements were performed using a Texture Analyzer, while digital image analysis was used for color measurement. The results showed that RF postdrying of partially baked cookies resulted in lower acrylamide levels (107.3 ng/g for control cookies, 74.6 ng/g upon RF postdrying of cookies partially baked for 9 min, 51.1 ng/g upon RF postdrying of cookies partially baked for 8 min). Instrumental texture analysis showed no significant difference among the texture of cookies, whereas RF postdried samples had a lower degree of browning. According to sensory evaluation results, control had a more crumbly texture, and RF postdried sample that was conventionally baked for 8 min had a slightly uncooked flavor. Practical Application: Combining radio frequency and conventional baking may provide cookie manufacturers with ability to make cookies with lower levels of acrylamide. 相似文献

以面粉、油、糖为主要原料制作曲奇饼干,通过测量其水分含量、色度、质地、感官和丙烯酰胺含量,研究原料特性对曲奇饼干品质和丙烯酰胺生成的影响。实验表明:面粉中蛋白质的含量显著影响曲奇饼干的品质和丙烯酰胺的生成。与高筋粉和中筋粉相比,低筋粉粗蛋白含量仅为7.67%,其制作的曲奇饼干水分含量低,硬度小,柔软和酥松程度表现更好,品质最佳且丙烯酰胺生成量最低。普通黄油和发酵黄油制作的曲奇饼干酥脆,香味浓郁,品质优良,发酵黄油在焙烤过程脂肪氧化较为缓慢,生成的丙烯酰胺含量低为212μg/kg。红糖制作的曲奇饼干呈棕褐色,具有独特的香味,但丙烯酰胺含量高达828μg/kg。白砂糖、冰糖和绵白糖制作的曲奇饼干品质差异较小,其中白砂糖制作的曲奇饼干感官评价得分最高,丙烯酰胺含量最低为230μg/kg。综上,低筋面粉、发酵黄油和白砂糖制作的曲奇饼干品质较优,丙烯酰胺生成量较少。 相似文献

ABSTRACTThe restructured cookies were made from old stalks of asparagus (Asparagus officinalis). Combination of vacuum infrared radiation drying and pulse-spouted microwave vacuum drying (VIRD–PSMVD) was studied as a potential mean for dehydration of restructured cookies. The samples were first dried by VIRD and then by PSMVD to final moisture content less than 6%. Expansion ratio, texture, color, flavor, and other attributes of samples dried by this method were evaluated and compared with those dried by PSMVD and VIRD. Results showed that the samples dried by VIRD–PSMVD showed higher overall acceptability, crisper texture, and higher expansion ratio. 相似文献

采用天然抗氧化剂荞麦、孜然和黑种草籽抑制曲奇中丙烯酰胺的生成。研究这3种配料对面粉中丙烯酰胺前体的含量、面粉和曲奇抗氧化的特性、曲奇烘焙特性和丙烯酰胺含量的影响,结果表明:这3种配料组合都可以增加面粉中还原糖和天门冬酰胺的含量,也可以增加面粉和曲奇的抗氧化特性(包括总酚类物质、DPPH自由基清除能力和ABTS+·的抑制能力)。当所添加的天然抗氧化剂含量增加时,曲奇颜色变深,表现为更低的L*,a*和b*值;荞麦和孜然的引入会增加曲奇中的水分含量,而黑种草籽则相反。所有天然抗氧化剂组合都可以增加曲奇的延展率。未添加天然抗氧化剂的曲奇中丙烯酰胺的含量为361.2μg/kg,而单独添加15%荞麦、15%孜然和15%黑种草籽使得曲奇中丙烯酰胺的含量分别降低了20.2%、67.6%和75.9%。感官分析结果表明:富含天然抗氧化剂的曲奇都可以被人们所喜欢。 相似文献

Methanolic extracts of rice bran (MRB) were found to be the richest in phenolics than all the other extraction media, i.e. water, 80% methanol, 70% ethanol, diethyl ether. Thermal stability of MRB was determined by evaluating antioxidant activity of heated extracts in linoleic acid system. Cookies were prepared in sunflower oil premixed with MRB at different concentrations, i.e. 500, 1000 and 2000 ppm, and with butylated hydroxytoluene and α‐tocopherol at 200 ppm. Oxidative stability of cookies was measured by storing under ambient conditions for an year with periodical analysis after every 2 months. Fatty acid composition was determined by gas–liquid chromatography. A regular decrease in unsaturated fatty acids (USFA) and increase in saturated fatty acids was observed with the increase in storage period; all the stabilised samples showed appreciably less decrease in USFA than that of control sample. Induction period ranged from 14.73 to 31.22 h while control exhibited 7.5 h. Peroxide value, iodine value and free fatty acids were chosen as the parameters for quality evaluation of cookies. Results suggest rice bran to be a potential source of antioxidants for stabilisation of cookies. 相似文献
