Isotermas de Adsorción by Arlette Huerta on Prezi

Physical properties for foods. Net isosteric heat of sorption in dried fruits, J Food Eng. Dordrecht, Netherlands, Thermodynamics properties of food in dehydration. Both molecules form semicrystalline superstructures with crystalline and amorphous layers arranged in an onion-like structure where most of the crystalline adsrocion are formed by amylopectin although isotwrmas of the amylose molecules are also present in them Zobel, ; Brett et al. Hexane, iso -octane, iso -dodecane and toluene were used as the hydrophobic phase, and bidistilled water was used as the water phase.

One of the most important aspects concerning oat quality is its moisture content, since many of its physical properties depend on this property Prieto et al.

Analysis of starch and other main constituents of cereal grains. Isotermxs the isotermaz hand, the Oswin model has been used with meat and fruits Boquet et al. Studies in Interface Science 6, A study of captive bubbles with axisymmetric drop shape analysis. The oat flake moisture sorption isotherms showed a clear dependence on temperature for the working values in this study.

Properties of water in foods in relation to quality and stability.

A common practice is to correlate the experimental data through mathematical models, which render satisfactory results in certain a w ranges and certain food types Zhang et al. Journal of Colloid and Interface Science 83, Isotegmas in dried fruits. Oat flakes are an important raw material in the isoteras industry Gates, In more recent years, the GAB isotherm equation has been widely used to describe the sorption behavior of foods Bizot, ; Weisser, ; Iglesias et al. Water sorption characteristics of six rowbarley malt Hordeum vulgare.

The purpose of this study was to experimentally determine the equilibrium moisture curves of oat flakes Avena sativa L. The recommended storage conditions of oat flakes include: Besides, it defines the storing conditions that guarantee food stability Correa isotermad al.

Water adsorption isotherms of texturized soy protein.

Increasing water activity causes an increase in the availability of the polar sites to the water molecules Al-Muhtaseb et al. Within such a system, amorphous zones are more water-accessible than crystalline regions in which the intermolecular interactions between the chains are too strong to allow solvent penetration.
