Di-(2-ethylhexyl) phthalate (DEHP) accumulates in blood brought into contact with materials utilizing this compound as a plasticizer. To determine whether this phthalate diester affects red blood cell integrity, we have compared cell morphology, plasma hemoglobin accumulation, micro-vesicle production, and the concentration of intracellular metabolites and electrolytes of erythrocytes from bloo...

Quality changes of Eastern little tuna (Euthynnus affinis) slices treatedwith caffeic or tannic acid (0.2 g kg 1) and the control during 15 days of refrigerated storage in air or under modified atmospheric packaging (MAP: 60% CO2, 35% N2, 5% O2) were studied. Tannic acid exhibited a greater preventive effect on metmyoglobin (metMb) formation and lipid oxidation than did caffeic acid (P < 0.05)....

Seventy-three billion chicken eggs are produced annually in the United States. However, less than 0.1% of these eggs are exported. Increasing the shelf-life of eggs may increase export sales. The goal of this research was to determine whether food-grade coatings on eggs may extend shelf-life under refrigerated storage. Four food-grade coatings were selected: paraffin wax, mineral oil, soy prote...

Improved production methods of starter cultures, which constitute the most important element of probiotic preparations, were investigated. The aim of the presented research was to analyse changes in the viability of Lactobacillus. acidophilus and Bifidobacterium bifidum after stabilization (spray drying, liophilization, fluidization drying) and storage in refrigerated conditions for 4 months. T...

Campylobacter jejuni is the most common thermophilic Campylobacter associated with human enteritis in many countries. Broilers and their by-products are the main sources for human enteritis. Refrigeration and freezing are used to control bacterial growth in foods. The effect of these interventions on survival of Campylobacter jejuni is yet not quite understood. This study evaluated the effect o...
