Model for internal porosity development of different shaped foods

Senadeera, Wijitha (2014) Model for internal porosity development of different shaped foods. In Thilakarathne, BMKS, Rathnayake, HMAP, Champa, WAH, & Wasala, WMCB (Eds.) Proceedings of the International Research Symposium on Postharvest Technology, Research and Development Centre, Institute of Post Harvest Technology, Anuradapura, Sri-Lanka, pp. 114-120.


Three particular geometrical shapes of foods were prepared from food materials. Cuboidal (aspect ratio = 1:1, 2:1, 3:1) , cylindrical (length: dameter = 1:1, 2:1, 3:1) and spheres were selected from potato, beans and peas respectively. Internal porosity was determined from solid density (theoretical)and particle density (experimental) during fluidised bed drying at different moisture contents. Solid density was calculated using formulae (conservation of mass and volume) already published in the literature by previous researchers. Determined porosity values were correlated with moisture ratio for different geometrical shapes.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
