Abstract
his study was conducted to investigate the efficiency of magnetic system in milk sterilization. This was done using bacteriological, (total microbial count) and cytogenetic (mitotic index and chromosomal aberration of bone marrow) investigations. Results indicated a reduction in total milk microbial count. On the other hand, mitotic index was increased and chromosomal aberration in bone marrow was decreased in magnetic milk as compared with raw milk. In conclusion, milk sterilization might performed using magnetic field application.
Highlights
Milk is sterile within the udder, it might be bacterial contaminated before its secreted from the udder
Except for mastitis that caused by infectable types of bacteria (Staphylococcus aureus, Streptococcus uberis and Coliform spp), the bacteria in this position is undeteimable and harmless
For Static magnetic fields (SMF), the magnetic field intensity is constant with time, whereas, oscillating magnetic fields (OMF) is usually applied in the form of either constant or decaying amplitude sinusoidal waves [5]
Summary
Milk is sterile within the udder, it might be bacterial contaminated before its secreted from the udder. للميكروبات ومن جانب اخر زيادة في معامل الانقسام مع انخفاض في عدد الانحرافات الكروموسومية في The objective of this study was to evaluate the anti-microbial effect of raw milk using SMF, and to examine the influence of this magnetic milk on chromosomal aberration of mice. The bacterial isolations included Listeria momocytogenes, Staphylococcus aureus, Lactobcillus delbrueckii, Streptococcus thermophillus, Aspergillus niger and Escherichia coli Table (1), showed the mean values of numbers of colonies in both raw and magnetic milk.
