products because they are easy to handle. Microbiological safety of liquid products is mainly guaranteed by pasteurization ( Lechevalier et al., 2017 ). Consequently, there are many standardizations of the heat-treatment. The USDA requires liquid egg
arranged randomly to form the bulk structure. Also apparent between the crystallites and grains were pores, into which electrolyte is expected to permeate during electrochemical discharge.
Heat treatment of γ-MnO 2
Heating and/or cooling of substances is one of the oldest and basic methods for preparing materials with defined properties.
This always leaves a definitive fingerprint of the thermal history. Beside knowing the structure we need to specify such materials
by their thermodynamic behaviour, i.e., stability/metastability, phase relations and transitions, particularly establishing
corresponding characteristic points. All this can be based on ordinary thermodynamics but its validity must be approved for
non-equilibrium conditions of temperature changes where equilibrium and kinetic effects overlap. The slower the phase transition
proceeds the greater is the deviation of the system state (kinetic curve) from its equilibrium state (equilibrium background).
This makes possible to locate the actual phase boundary between two states investigated, resulting in the so-called kinetic
phase diagrams. Most of modern technologies are intentionally based on non-equilibrium phenomena in order to create metastable/nonstable
phases of specific properties. In this sense thermal analysis is understand as the method for determining the sample state
on the basis of the sample interactions with the surroundings whose intensive parameters are controlled. Temperature is here
considered as a basic parameter that connects all thermophysical measurements and thermal treatments.

Introduction Heat treatment is a routine operation in food production since it effectively destroys microorganisms that cause spoilage in food, thereby increasing the shelf life of products. At the same time, high temperatures may have a negative
