Characterisation of potato crisp effective porosity using micro-CT (2016)
Journal Article
Renshaw, R. C., Robinson, J. P., Dimitrakis, G., Bows, J. R., & Kingman, S. W. (2016). Characterisation of potato crisp effective porosity using micro-CT. Journal of the Science of Food and Agriculture, 96(13), 4440-4448. https://doi.org/10.1002/jsfa.7655

Background

The effective porosity is an important quantitative parameter for food products that has a significant effect on taste and quality. It is challenging to quantify the apparent porosity of fried potato crisps as they have a thin irregular... Read More about Characterisation of potato crisp effective porosity using micro-CT.
