摘要: 将香菇粉以不同添加量(1%、3%、5%、7%、9%)置于干脆面面团中,通过测定干脆面面团的淀粉糊化特性、质构特性、动态流变学特性及油炸后干脆面水分和油脂含量、油脂分布,探讨不同添加量的香菇粉对干脆面面团的流变性能及干脆面油炸后油脂渗透的影响。结果表明:随着香菇粉添加量逐渐增加,干脆面面团的峰值黏度、谷值黏度以及最终黏度显著下降,面团硬度增加,黏聚性、弹性以及弹性模量和黏性模量先下降后上升。当香菇粉添加量为5%时,干脆面的水分含量最高,油脂含量最低,此时干脆面的内部结构紧密,荧光强度最弱,油脂分布均匀。结果表明,在干脆面面团中添加适量香菇粉能改变干脆面面团的流变性能,抑制干脆面在油炸过程中的油脂渗透。

Abstract: In this study, micronized shiitake powder was added to crispy instant noodle dough in different amounts (1%, 3%, 5%, 7%, and 9%). By measuring the starch gelatinization properties, texture properties and dynamic rheological properties of dough, and the moisture content and oil content and distribution of crispy instant noodles, we investigated the effect of the addition of different amounts of shiitake on dough rheological properties and oil penetration into crispy instant noodles. The results showed that with increasing level of shiitake addition, the peak viscosity, trough viscosity and final viscosity of dough significantly decreased, hardness increased and cohesiveness, elasticity, and elastic modulus and viscous modulus decreased first and then rose. The crisp instant noodles with 5% shiitake powder had the highest moisture content and the lowest oil content. A dense internal structure was observed in the noodles, which exhibited the weakest fluorescence intensity and an even oil distribution. The results show that adding a proper amount of shiitake powder to dough can change its rheological properties, and inhibit the penetration of oil during the frying process of crisp instant noodles.

Key words: shiitake powder, crisp instant noodle dough, rheological properties, oil distribution
