| Abstract | Physico-chemical characteristics of concentrated tomato products and ketchup as well as their influence on packaging materials were investigated. For this purpose colour, acidity, hydroxymethylfurfural (HMF), and pH and rH values were determined. Porosity of organic coating on aluminium tube was determined by chemical (Alizarine S) and elektrochemical (Ettinger) methods. Investigations were carried out in fixed intervals during nine months of storage at 277 K. A correlation between physico-chemical changes of food stuff and packaging material deterioration was determined. |
