摘要: 为优化挤压膨化芝麻制品的食用品质,以芝麻粉、淀粉、大豆分离蛋白和蔗糖为主要原料,采用模糊感官综合评价结合混料试验设计对挤压膨化芝麻制品配方进行优化。结果表明:挤压膨化芝麻制品的脆度、硬度与模糊感官评分之间极显著相关(P<0.01),模糊感官评分可以作为评价产品品质的指标;主要原料及其之间的交互作用对挤压膨化芝麻制品的感官品质影响极显著(R2=0.9971,P<0.01)。当淀粉添加量65%、芝麻粉添加量12.5%、大豆分离蛋白添加量8%、蔗糖添加量14.5%时,挤压膨化芝麻制品的模糊感官评分具有最佳分值89.4±0.86,与模型预测值无显著性差异(P>0.05)。扫描电镜结果显示,优化产品的结构紧密、表面较平整、无明显颗粒状态。研究结果能够为芝麻的综合利用及新产品的开发研究提供一定参考。

Abstract: Sesame flour, starch, soybean protein isolate (SPI) and sucrose were mixed and extruded in this study, and the formulation was optimized to improve the eating quality using fuzzy evaluation and mixture design. The results showed that there was a significant correlation of fuzzy evaluation scores with crispness and hardness (P < 0.01). Fuzzy evaluation scores could be considered as an indicator to evaluate the quality of extruded products. The effects of the four components and their interaction on the sensory quality were significant (R2 = 0.997 1, P < 0.01). The optimal combination that provided maximum fuzzy evaluation score (89.4 ± 0.86) was starch 65%, sesame flour 12.5%, SPI 8% and sucrose 14.5%. There was no significant difference between the sensory evaluation and the predicted value (P > 0.05). Scanning electron microscope (SEM) images showed that the surface of the product was structurally compact, even and smooth and without obvious bulges. These results can provide a basis for the comprehensive utilization of sesame and the development of new products.
