چکیده مقاله:

To survey the relationship between crumb image and some dough rheological features (adhesiveness, cohesiveness, hardness, stickiness, resilience and chewiness) of Barbari bread based on dough proofing time (20-60, min), mixing time in low (2-8, min) and in high speed (2-8, min) acentral composite rotatable design was applied. Results revealed that both crumb ΔE and crumb lightness of bread had a noticeable correlation with dough cohesiveness (r= 0.53, r= -0.63) and dough chewiness (r= -0.64, r= 0.50), respectively. Besides, crumb lightness may be presumably considered as an indicator for dough adhesiveness (r= 0.63), stickiness (r= 0.60). Also, crumb ΔE may be likely used for study of dough hardness variation (r= -0.56) and resilience (r= 0.50). Our finding showed that the variation of bread crumb color can be useful for study of some dough rheological behavior
