Effect Of Ultrasonic Processing On Food Enzymes Of Industrial Importance, 2016 Dublin Institute of Technology
Effect Of Ultrasonic Processing On Food Enzymes Of Industrial Importance, Paula Bourke, Brijesh Tiwari, Colm O Donnell, Patrick Cullen
In the last decade power ultrasound has emerged as an alternative processing option to conventional thermal approaches for pasteurisation and sterilisation of food products. While sonication alone is not adequate for inactivation of various spoilage and harmful enzymes present in food, ultrasound in combination with mild heat treatment and/or pressure has shown potential for both enzyme and pathogen inactivation. Numerous studies have investigated ultrasound for inactivating enzymes such as pectinmethylesterase, polyphenoloxidases and peroxidases responsible for deterioration of fruit & vegetable juice and various enzymes pertinent to milk quality. The efficacy of ultrasound for the inactivation of enzymes in food is ...

Dietary Oil Composition Differentially Modulates Intestinal Endotoxin Transport And Postprandial Endotoxemia, 2016 Iowa State University
Dietary Oil Composition Differentially Modulates Intestinal Endotoxin Transport And Postprandial Endotoxemia, Venkatesh Mani, James H. Hollis, Nicholas K. Gabler
Background: Intestinal derived endotoxin and the subsequent endotoxemia can be considered major predisposing factors for diseases such as atherosclerosis, sepsis, obesity and diabetes. Dietary fat has been shown to increase postprandial endotoxemia. Therefore, the aim of this study was to assess the effects of different dietary oils on intestinal endotoxin transport and postprandial endotoxemia using swine as a model. We hypothesized that oils rich in saturated fatty acids (SFA) would augment, while oils rich in n-3 polyunsaturated fatty acids (PUFA) would attenuate intestinal endotoxin transport and circulating concentrations. Methods: Postprandial endotoxemia was measured in twenty four pigs following a porridge ...
