Influence of ethanol and electron-beam radiation on the acidity of pork muscle tissue
Annotation
We study the influence of ethanol pretreatment of the surface of pork full-piece muscle tissue and gotten from it forcemeat samples and muscle fiber samples by pH- 2 metry and microscopy methods. Ethanol pretreatment permitted to differentiate on the time scale manifestation of autolysis and microbial processes during storage of the samples in post-radiation period at +4C. We marked summarized stabilizing effect of ethanol and electron-beam radiation at varied dose 12.5 – 50.0 kGy on the acidity muscle tissue samples with their pH pre-servation at the normal level during 3 – 4 weeks. It is shown that conditions of ethanol pretreatment concretize preferential directivity of radiolysis and following autolysis. At that versus of electron-beam radiation absorbed dose in muscle tissue samples gene-rates selective culture mediums. Quality composition of forming culture medium prede-termines quantity, composition and morphology of microorganisms.
