Business associations and the food processing industry in Australia : how neoliberalism has reinforced employer collectivism

In this paper I argue that factors such as conflicting pressures for food regulation reform and continuing industry assistance programs have made conditions even more favourable for collective business interest representation in Australia's food processing sector. The push by firms for less onerous and more business-friendly regulation has run up against environmental and social pressures/or more rigorous regulatory controls, as awareness grows ofthe risks ofnew technologies. The case of the Australian Food and Grocery Council (AFGC) illustrates the issues. The extent to which this association participates directly in the design and implementation of public policy is indicative of a decline in the autonomy of politicians and the state bureaucracy vis-a-vis the ideology and interests of business.

Minimising colonic fermentation of high fructan foods : using food processing techniques to reduce levels of fructans in onion and garlic

Background: Irritable Bowel Syndrome (IBS) is a chronic functional disorder of the bowel, affecting up to 15% of Australian adults. Dietary triggers need to be identified and controlled. Researchers have shown that short chain carbohydrates, fructans (high in onion and garlic) play a major role in triggering IBS symptoms. Current dietary management aims to limit the intake of fructans in the diet. Another approach may be to use simple food processing to reduce fructans in foods.

Objective: To investigate if pickling will reduce fructan levels in garlic and shallots, and if pickled garlic and shallots reduce colonic fermentation, and  abdominal symptoms in human volunteers.

Design: Fructan levels of the garlic and shallots were measured using the Megazyme fructan assay. 18 volunteers (13 healthy and 5 IBS) participated in a single blinded, randomised cross over study. Subjects were randomly assigned to receive a breakfast (potato and salmon patty) that was either high (unprocessed) or low (processed/pickled) in garlic and shallots. Breath hydrogen was measured every hour over a ten hour period, and abdominal symptoms were assessed using validated questionnaires.

Outcomes: Pickling over a 12 day period significantly reduced fructan levels in both garlic (p=.0.00) and shallots (p=0.00). Consumption of the low fructan breakfast resulted in significantly lower breath hydrogen (p=0.05), abdominal pain (p=0.032), and wind (p=0.04).

Conclusion: Pickling results in significantly lowered fructan levels in problem foods- shallots and garlic, and lowered colonic fermentation and abdominal symptoms in both healthy and IBS volunteers. This study provides another dietary strategy for dietetic counselling of patients with IBS.

Thermal food processing optimization: Algorithms and software

The algorithms and graphic user interface software package ?OPT-PROx? are developed to meet food engineering needs related to canned food thermal processing simulation and optimization. The adaptive random search algorithm and its modification coupled with penalty function?s approach, and the finite difference methods with cubic spline approximation are utilized by ?OPT-PROx? package (http://tomakechoice. com/optprox/index.html). The diversity of thermal food processing optimization problems with different objectives and required constraints are solvable by developed software. The geometries supported by the ?OPT-PROx? are the following: (1) cylinder, (2) rectangle, (3) sphere. The mean square error minimization principle is utilized in order to estimate the heat transfer coefficient of food to be heated under optimal condition. The developed user friendly dialogue and used numerical procedures makes the ?OPT-PROx? software useful to food scientists in research and education, as well as to engineers involved in optimization of thermal food processing.

Assembly of the Nuclear Transcription and Processing Machinery: Cajal Bodies (Coiled Bodies) and Transcriptosomes

We have examined the distribution of RNA transcription and processing factors in the amphibian oocyte nucleus or germinal vesicle. RNA polymerase I (pol I), pol II, and pol III occur in the Cajal bodies (coiled bodies) along with various components required for transcription and processing of the three classes of nuclear transcripts: mRNA, rRNA, and pol III transcripts. Among these components are transcription factor IIF (TFIIF), TFIIS, splicing factors, the U7 small nuclear ribonucleoprotein particle, the stem–loop binding protein, SR proteins, cleavage and polyadenylation factors, small nucleolar RNAs, nucleolar proteins that are probably involved in pre-rRNA processing, and TFIIIA. Earlier studies and data presented here show that several of these components are first targeted to Cajal bodies when injected into the oocyte and only subsequently appear in the chromosomes or nucleoli, where transcription itself occurs. We suggest that pol I, pol II, and pol III transcription and processing components are preassembled in Cajal bodies before transport to the chromosomes and nucleoli. Most components of the pol II transcription and processing pathway that occur in Cajal bodies are also found in the many hundreds of B-snurposomes in the germinal vesicle. Electron microscopic images show that B-snurposomes consist primarily, if not exclusively, of 20- to 30-nm particles, which closely resemble the interchromatin granules described from sections of somatic nuclei. We suggest the name pol II transcriptosome for these particles to emphasize their content of factors involved in synthesis and processing of mRNA transcripts. We present a model in which pol I, pol II, and pol III transcriptosomes are assembled in the Cajal bodies before export to the nucleolus (pol I), to the B-snurposomes and eventually to the chromosomes (pol II), and directly to the chromosomes (pol III). The key feature of this model is the preassembly of the transcription and processing machinery into unitary particles. An analogy can be made between ribosomes and transcriptosomes, ribosomes being unitary particles involved in translation and transcriptosomes being unitary particles for transcription and processing of RNA.

RNA editing activity is associated with splicing factors in lnRNP particles: The nuclear pre-mRNA processing machinery

Multiple members of the ADAR (adenosine deaminases acting on RNA) gene family are involved in A-to-I RNA editing. It has been speculated that they may form a large multicomponent protein complex. Possible candidates for such complexes are large nuclear ribonucleoprotein (lnRNP) particles. The lnRNP particles consist mainly of four spliceosomal subunits that assemble together with the pre-mRNA to form a large particle and thus are viewed as the naturally assembled pre-mRNA processing machinery. Here we investigated the presence of ADARs in lnRNP particles by Western blot analysis using anti-ADAR antibodies and by indirect immunoprecipitation. Both ADAR1 and ADAR2 were found associated with the spliceosomal components Sm and SR proteins within the lnRNP particles. The two ADARs, associated with lnRNP particles, were enzymatically active in site-selective A-to-I RNA editing. We demonstrate the association of ADAR RNA editing enzymes with physiological supramolecular complexes, the lnRNP particles.
