The aim of the study was to investigate the effect of selected technological additives (NaCL, sodium lactate and lactic acid) on shelf life of ground meat. It was found that all the three substances cause reduced microbial growth. Dynamics of action in case of each of these substances vary and depend on their concentrations. A limitation in the feasible amount of applied additives may be their effect...
Emission of light as a result of biochemical activities of some living bacteria Vibrio fischeri (in the past known as Photobacterium phosphoreum) makes it possible to monitor environmental changes in ecosystems. Toxicity testing as an international standard operating procedure based on the use of this method has already been accepted. The bioluminescent test offers a rapid, simple and sensitive method...
The effect of storage on the cholesterol oxidation products (COPs) content, lipid oxidation, hydrolytic changes, pH, ascorbic acid and nitrite contents in "piwna" and "mortadela" type sausages was studied. All the parameters were examined after 1, 3, 6, 8, 10 days of storage at 4°C in the case of the "mortadela" type sausage, and after 1, 3, 8, 10, 13, 15, 17 days of...
The effect of storage on the cholesterol oxidation products (COPs) content, lipid oxidation, hydrolytic changes, pH, ascorbic acid and nitrite contents in metka sausage was studied. All parameters were examined after 1, 7, 14 days of storage at 4°C in darkness. Statistical analysis showed influence of storage time on all parameters. Significant increase (p = 0.05) of peroxide value, acid number and...
The effect of storage on the contents of cholesterol, its oxidation products (oxysterols), lipid oxidation and hydrolytic changes in liver pate type sausage was studied. Lipid oxidation, hydrolysis and oxysterols level were examined after 1, 3, 6, 8 and 10 days of storage at 4°C. 7b-hydroxycholesterol and 7 ketocholesterol were the major cholesterol oxidation products formed in samples during storage...
Nowadays, according to expectations of consumer, meat products should be attractive from sensoric point of view, stable and safe. For consumers buying now more products in retail shops, colour is an important criterion by which they evaluate and choose meat products. Due to opinion of consumer, colour reflects proper composition of product, in particularly relation of meat to other compounds, freshness...
