Food Fragmentation by Human Mastication.

Fragment-size distribution has been studied experimentally by masticating raw carrot and fish gel. Lognormal distribution shows partly-good fit with various data. We have found that the fit of two-lognormals distribution is extremely good up to the entire region for masticated food fragments. The excellent data fitting by two-lognormals distribution implies that two main functions of mastication, a sequential fragmentation with randomness and size segregation, affect the size distribution of masticated food fragments. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
