Antiproliferative Effect of Green Papaya on Lymphocytic Leukemic Cells - Juniper Publishers

Image
  Nutrition and Food Science International Journal - Juniper Publishers Abstract Numerous edible plants have been reported to interfere with the carcinogenic process, and therefore, the regular consumption of these plant products may reduce the risk of developing cancer. We investigated the effect of papaya fruit and leaves on the cell proliferation of Jurkat T-lymphocytic and Daudi B-lymphocytic leukemia cells. Cells were treated with aqueous or methanolic extracts from leaves, skin, pulp, and seeds from green papaya. The papaya fractions were tested for total phenolic content, total flavonoids content, and anti-oxidation activity using chemical assays. Cell proliferation was measured using a WST-1 assay. Our data indicate that methanol and water extracts of seeds and leaves contained higher concentrations of total phenolic compounds and higher anti-oxidation activity than that of extracts from skin and pulp. Both methanol and water extracts from leaves and skin potently inhibited...

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...
