MODELS OF SORPTION ISOTHERMS FOR FOOD: USES AND LIMITATIONS

Abstract

Moisture sorption isotherms describe the relationship between moisture content and water activity in food. This work presents basic concepts related to the sorption thermodynamics of water, the classification of isotherms, “uses and limitations of the models”, and measurement of sorption isotherms for food materials. The most commonly used models in food are Brunauer-Emmett-Teller and Guggenheim-Anderson-de Boer. The success of the Brunauer-Emmett-Teller model is rather qualitative, considering that almost all cases are linear only in a limited rank of water activity from 0.05 to 0.45, as its main applicability is the estimation of surface areas. And, the use of the Guggenheim-Anderson-de Boer model is generalized by its theoretical bases, mathematical simplicity, and ease to interpret; but it is not frequently used when the water activity greater than 0.93.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
