Saffron extracts of two different concentrations were prepared and used as a source of natural antioxidants in whole wheat flour cookies. The effect on the color, texture and sensory properties of the product was also studied over a storage period of 9 months. Results revealed that spread ratio and hardness of cookies reduced non-significantly with the addition of saffron extract (SE). Color values '' and '' of cookies increased significantly from 50.7 to 53.9 and 36.5 to 47.0, respectively with the addition of SE while '' value decreased non-significantly ( > 0.05). DPPH radical scavenging activity, reducing power and inhibition of lipid peroxidation of dough and cookie samples containing SE were enhanced in comparison to control. The concentration of crocins, safranal and picrocrocin in DS and DS dough samples was found as 28.30, 48.30, 104.6 µg/g and 35.14, 62.38, 118.2 µg/g, respectively. Sensory scores of cookies containing SE were high as compared to control. All the quality parameters of cookies reduced during the storage period (0-9 months). However, the cookies with added SE revealed significantly higher quality attributes up to 6 months of storage without any significant loss in quality.
制备了两种不同浓度的藏红花提取物,并将其用作全麦面粉饼干中的天然抗氧化剂来源。还研究了其在9个月储存期内对产品颜色、质地和感官特性的影响。结果表明,添加藏红花提取物(SE)后,饼干的展开率和硬度降低,但差异不显著。添加SE后,饼干的颜色值“a*”和“b*”分别从50.7显著增加到53.9和从36.5显著增加到47.0,而“L*”值降低但差异不显著(P>0.05)。与对照相比,含有SE的面团和饼干样品的DPPH自由基清除活性、还原能力和脂质过氧化抑制作用增强。在DS和DS面团样品中,藏红花素、藏红花醛和苦藏花素的浓度分别为28.30、48.30、104.6μg/g和35.14、62.38、118.2μg/g。与对照相比,含有SE的饼干的感官评分较高。在储存期(0 - 9个月)内饼干的所有质量参数均下降。然而,添加SE的饼干在储存6个月内显示出显著更高的质量属性,且质量没有任何显著损失。
