METHOD FOR THE DETERMINATION OF PHYSICAL-CHEMICAL CHANGES AT STORAGE OF FOODSTUFFS

摘要

A method for the determination of physical-chemical changes at storage of foodstuffs wherein one determines adsorption heat of porous products, bond energy of water to product L by formula L=RxTxln,wherein- gas constant;- absolute temperature;- relative air humidity;And from those the physical-chemical changes in products are determined by entropy by formula:,wherein- adsorption;- free energy of water binding to product;- specific heat of evaporation of free water;- absolute temperature
