Quality And Shelf-Life Of Fresh Cut Crrot Slices As Affected By Slicing Method, Catherine Barry-Ryan, David O'Beirne Prof
Quality And Shelf-Life Of Fresh Cut Crrot Slices As Affected By Slicing Method, Catherine Barry-Ryan, David O'Beirne Prof

The effects of slicing method on the quality and storage-life of modified atmo¬sphere packaged carrot slices were determined using microscopy, sensory evalu¬ation, microbial counts and a range of physical and chemical tests. Slicing caused physical damage, physiological stress and enhanced microbial growth. The se¬verity of these effects were in the order of blunt machine blade > sharp machine blade > razor blade. These findings provide insights into the magnitude and ba¬sis of slicing effects and also confirm the importance of gentle processing and the use of a sharp blade.
Ascorbic Acid Retention In Shredded Iceberg Lettuce As Affected By Minimal Processing, Catherine Barry-Ryan, David O'Beirne
Ascorbic Acid Retention In Shredded Iceberg Lettuce As Affected By Minimal Processing, Catherine Barry-Ryan, David O'Beirne

The effects of slicing method, packaging atmosphere and storage temperature were determined on total ascorbic acid (TAA) content of modified atmosphere packaged shredded lettuce. TAA was extracted from the lettuce samples and levels were monitored using either titration with 2,6-dichlorophenolindophenol solution or an assay kit. Slicing affected (p < 0.05) ascorbic acid retention in the order manual tearing > manual slicing > machine slicing. Flushing with 100% nitrogen increased retention (~5%, p < 0.05) over packages with product modified atmospheres. Storage at 3°C increased retention (~20%, p < 0.05) compared with storage at 8°C. Scores for product appearance generally followed losses of TAA in the lettuce (p < 0.05).

Persistent hypoglycaemia in infancy is most commonly caused by hyperinsulinism. A case is reported of the somatic loss of the maternal 11p in an insulin secreting focal adenoma in association with a germline SUR-1mutation on the paternal allele in a baby boy with hyperinsulinism diagnosed at 49 days old. A reduction to homozygosity of an SUR-1 mutation is proposed as a critical part of the cause of focal hyperinsulinism.
