Effect of storage at ambient temperature on quality of donut
Journal Title: Agricultural Advances - Year 2013, Vol 2, Issue 4
Abstract
This work was carried out to study the influence of storage time (1-7 days), on the quality of donut. Rheological properties, crumb and crust color and Donut’s brain cavity were used as quality indicators. Results show that significant changes occurred on storage in all textural properties. The hardness, Gumminess and chewiness of the donut showed a significant increase with the time of storage. L* a* b* color parameters of crust don't change significantly. The most noticeable change in color parameters of crumb was observed in ∆E. Average diameter of donut’s brain cavity decreased within the storage time of seven days. Average area of cavities decreased too but circularity of cavities increased. The best time for consumption of donut was calculated as 4.8 days in the based on simple kinetic model.
