Effect of polysaccharide stabilizers on the rate of growth of ice

MUHR, A. H., BLANSHARD, J. M. V.·1986·International Journal of Food Science & Technology

Abstract

Measurements of the linear rate of advance of ice into undercooled aqueous solutions and gels have been made. The solutes consisted of sucrose with smaller quantities of other substances, mostly polysaccharides. The linear crystallization velocity in sucrose solutions is mainly governed by the rate of diffusion of sucrose molecules, and the addition of soluble polysaccharides causes only a small extra retardation. However, the growth of ice into undercooled sucrose solutions is drastically retarded and altered in morphology by the presence of a gel network. This effect is discussed qualitatively in terms of the interaction of the ice front with the gel fibres, which reduces the equilibrium freezing point and may lead to rupture of the fibres.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ice crystals in a gel network grow either by water molecule migration from the network to the ice front or by penetration of the ice front through the micropores of the network, requiring overcoming both the hydraulic resistance of the gel and the resistance generated by network contraction.

    “Regarding steric interference, Muhr and Blanshard [42] reported that ice crystals in a gel network grow either by water molecule migration from the network to the ice front or by penetration of the ice front through the micropores of the network. This process requires overcoming both the hydraulic resistance of the gel and the resistance generated by network contraction [43].”

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.
