Bacteriophages as Preservation Agents to Promote Minimally Processed Food Safety - Juniper Publishers

Image
  Nutrition and Food Science International Journal - Juniper Publishers Abstract Foodborne disease related to ready to eat products contaminated by foodborne pathogens is a global concern due to its impact on human health and economy worldwide. Minimally processed food like ready to eat fruits and vegetables are not subjected to common preservation processes, additionally, the use of antibiotics and chemicals for pathogens eradication may affect consumers health. Baceriophages or viruses that infect bacteria have been suggested as bio-control tools and advantageous bio-preservation agents to promote minimally processed food safety. Recent studies show a reduction of pathogens after application of phages cocktails on fresh produce. Usefulness of broad-host range bacteriophages as bio-preservation agents needs more investigation.

Child Care Food Safety Hand Hygiene: The Role of the Director - Juniper Publishers

Image
  Nutrition and Food Science International Journal - Juniper Publishers Abstract In the United State over 15 million children attend a childcare facility annually. These children are 3.5 times more likely to contract a foodborne illness than children cared for in other settings. Proper hand hygiene practices have been identified as the most important practice to mitigate the spread of foodborne illnesses. Thus, the aim of this study was to explore hand hygiene training opportunities given to childcare food handlers in childcare facilities; as well as explore what food safety training childcare directors currently possess. Results showed directors received food safety training yet did not always pass the training along to their employees. A lack of written hand hygiene policies was identified, as well as lack of childcare employee training for hand hygiene on the topics of hand washing and glove use. It is recommended that childcare directors communicate the importance of proper han...

Influence of oligochitosans and highly molecular chitosan on Lactobacillus bulgaricus cultivation - Juniper Publishers

Image
  Nutrition and Food Science International Journal - Juniper Publishers Abstract It was established that decrease of oligochitosans with molecular masses 7.0, 25.4, 45.3 kDa concentration in the process of Lactobacillus bulgaricus cultivation leads to fermented dairy product pH reduction and titratable acidity increase. Further increase in titratable acidity and decrease of lactic acid microorganisms’ amount was determined during the fermented dairy product storage process. Oligochitosans with molecular masses 7.0, 25.4, 45.3 kDa in concentrations interval from 0.0025 to 0.01 per cent did not exhibit prebiotic properties. Active acidity elevation and titratable acidity depression was observed at the chitosan with molecular mass 350 kDa concentration rises. Also increase of highly molecular chitosan concentration leads to elevation of lactic acid microorganisms’ total amount, which was more than three degree as many as total count of lactic acid bacteria in control sample.
