Accumulation Of Phycotoxins In The Mussel Mytilus Galloprovincialis From The Central Adriatic Sea, Maja Pavela-Vrančić, Ivana Ujević, Živana Ninčević Gladan, Ambrose Furey Jul 2006

Accumulation Of Phycotoxins In The Mussel Mytilus Galloprovincialis From The Central Adriatic Sea, Maja Pavela-Vrančić, Ivana Ujević, Živana Ninčević Gladan, Ambrose Furey

Physical Sciences Publications

Surveys of DSP (Diarrheic Shellfish Poisoning) toxin profiles in the mussel Mytilus galloprovincialis from coastal waters of the central Adriatic Sea, over the years 1995 to 2001, demonstrate that incidents of shellfish toxicity in this area are dominated by the occurrence of okadaic acid (OA) and a PTX derivative, 7-epi-pectenotoxin-2-seco acid (7-epi-PTX-2SA). Toxin composition and the relative ratio of toxic components in shellfish is in correlation with the occurrence of DSP producing organisms from the Dinophysis species along with Prorocentrum micans and Lingulodinium polyedrum. The occurrence of D. sacculus shortly before the appearance of OA in shellfish implicates its possible …


The Development Of Functional Food Ingredients From Yeast Cell Wall Beta Glucans, Susan Keogh Jan 2006

The Development Of Functional Food Ingredients From Yeast Cell Wall Beta Glucans, Susan Keogh

Theses

The intracellular contents of spent yeast can be used to produce flavours and flavour enhancers. However there still remains after this process, a significant quantity of cell wall material, which makes up 20-25% of the dry weight of yeast biomass. A major component of the yeast cell wall is the polysaccharide P-glucan. This project involved the investigation of the extraction and characterisation of p-glucan as well as its evaluation as a functional food ingredient. A preparation of spent yeast p-glucan was obtained from two types of spent yeast species, Saccharomyces cervisiae (brewers yeast) and Kluyveromyces marxianus (dairy yeast) obtained from …


System Identification Of A Pasteurisation Process: A Comparison Of Direct And Indirect Methods, Niel Canty Jan 2006

System Identification Of A Pasteurisation Process: A Comparison Of Direct And Indirect Methods, Niel Canty

Theses

The primary focus of this research is to identify a linear model for a direct steam injection (DSI) pasteurisation process which is a component of a large-scale pilot evaporation process widely used in the dairy industry. The pasteurisation process has been identified as a key component of the evaporation process. The author believes that no previously published work has focused on identifying models for a DSI pasteurisation process which makes this work an original contribution to the area. The pasteurisation process can be modelled as a single-input, single-output (SISO) process with a measurable disturbance. Thus two transfer functions were required …
