Australian sweet lupin kernal fractions as palatable functional food ingredients

Australian sweet lupin kernal fibre addition to foods in the diet beneficially modified serum lipids and the food products palatability was not reduced after repeated consumption. Australian sweet lupin kernal flour addition to white bread lowered the glycaemic index and did not reduce palatability, but increased the insulinaemic index.

Marine nutraceuticals : glucosomine and omega-3 fatty acids : new trends for established ingredients

Glucosamine and long-chain omega-3 lipid are the two most widely consumed marine nutracuticals. These   ingredients have been used as dietary supplement ingredients for many years, but  are now becoming important functional food and beverage ingredients. The production of GRAS and vegetarian glucosamine has led to increased use of this ingredient in beverages in particular. For long chain omega -3 lipid the development of stabilisation technologies has been critical for the increased use of these lipids in functional foods. The development of new sources of both of these ingredients, together with novel delivery and application technologies, will continue to drive increased consumption of these marine nutracuticals, in particular as functional food and beverage ingredients.

Microencapsulation of tuna oil fortified with the multiple lipophilic ingredients vitamins A, D3, E, K2, curcumin and coenzyme Q10

Complex coacervates of gelatin and sodium hexametaphosphate (SHMP) was used to microencapsulate tuna oil fortified with the multiple functional lipophilic ingredients, vitamin A, D3, E, K2, curcumin and coenzyme Q10. An emulsion homogenization speed of 15,000 rpm for 15 min resulted in low surface oil content (0.08%), high encapsulation efficacy (99.84%) and encapsulation yield (96.59%), with a significantly enhanced oxidative stability index (6.23 h). The Fourier transform infrared spectra showed that there was no observable oxidation of the oil during microencapsulation. This study shows that microencapsulation using complex coacervation is suitable for stabilizing multiple bioactive lipophilic ingredients.

Prescription and over-the-counter pain medication in arthritis: awareness of active ingredients and attitudes to medication borrowing and sharing

Background:
Many Australians with arthritis self-manage their pain with prescription and/or over-the-counter pain medications, containing paracetamol. If taken appropriately, these medications are relatively safe; however, if mismanaged through patients' iinability to understand medication labels and instructions, these medications may cause adverse drug events and/or toxicities.
Aim:
This study explored the prescription and over-the-counter pain medications most commonly used by people with arthritis and the ability of these patients to correctly identify paracetamol as an active ingredient in commonly available preparations. The study also investigated the functional health literacy of these patients and their inclination to borrow and/or share pain medications.
Method:
Adult participants diagnosed with arthritis were invited to complete an anonymous survey which included questions about their prescription and over-the-counter pain medications; their medication borrowing and sharing behaviours; their functional health literacy; and their knowledge about preparations containing paracetamol as an active ingredient.
Results:
Most of the 254 participants used analgesic agents containing paracetamol, as combination tablets (paracetamol 500 mg and codeine 30 mg) or paracetamol-only tablets (paracetamol 665 mg) to self-manage their pain. Respondents with low functional health literacy scores were significantly less likely to identify paracetamol as an active ingredient in both combination and paracetamol-only pharmaceutical products, and were more likely to guess or did not know how to identify that paracetamol was an active ingredient in these products. Almost 30% of the respondents indicated that they had and/or intended to borrow/share their over-the-counter
pain medications whereas less than 10% suggested that they had and/or intended to borrow/share their prescription pain medication.
Conclusion:
Australians with arthritis, especially those with low functional health literacy scores, self-managing their pain with paracetamol-containing products, do not always recognise paracetamol as an active ingredient in combination products, and may risk potential paracetamol-related adverse effects and/or toxicities.

An evaluation of the suitability of selected waste products in feeds for three fish species

Five types of aquatic food industry waste products (carp offal, carp roe, fish frames, trout offal and surimi processing waste) together with fish meal were evaluated for their suitability as potential fish meal replacements, partially or wholly, in diets for three species (rainbow trout, Murray cod and shortfin eel) cultured in Australia, using a number of criteria.

The proximate composition of the ingredients on a dry matter basis including protein content, lipid and ash, varied considerably. The essential amino acid (EAA) contents of the waste products and fish meal decreased in the order: carp roe > fish meal > carp offal > 'surimi' processing waste > fish frames > trout offal. The results of cluster analysis of A/E ratios of waste products and fish whole body fell within three clusters. The EAAI of whole body tissue of Murray cod, rainbow trout and Australian shortfin eel however, were closest to fish meal, followed by fish frame waste and/or 'surimi' waste. The results on A/E ratios and EAAI did not conform to the raw data on TAA and EAA. Therefore, the study emphasizes the need to have a multi-prong approach to determine the suitability of ingredients for incorporation into fish feeds.

The importance of audit committees in initial public offerings

This paper follows Balvers, McDonald and Miller (1988), and Beatty (1989), who find lower underpricing in Initial Public Offerings (IPOs) when prestigious auditors are used to attest to the IPO's financial statements. Australian IPOs are not obliged to nominate audit firms in the prospectus, but often identify that they will have audit committees so as to assist in more appropriate corporate governance. This paper analyzes if IPOs identifying the existence of audit committees in the prospectus have a lower underpricing return. While our findings are consistent with previous studies concluding that both the size of the new issue and the use of an underwriter are important ingredients in the level of underpricing return, the inclusion of an audit committee in the prospectuses has actually increased underpricing returns. The capital market may view the audit committee identification with some skepticism.

Psyshoanalysis and its discontents

There are only 5,000 patients in psychoanalysis with members of the American Psychoanalytic Association (APsaA), and these analysts are often viewed as arrogant and insular. As a laboratory for psychoanalytic institutions the APsaA provides crucial lessons for the future across the field. What ingredients are needed for psychoanalysis to be a vibrant discipline? What factors have prevailed where psychoanalysis is successful? The author explores the cases of Argentina and France, where psychoanalysis is relatively popular, and then returns to the U.S. situation. Insular mind-sets led to many missed opportunities for cultural and academic engagement in the United States. As an example, the author explores responses to the making of John Huston's film Freud: The Secret Passion. To become revitalized, psychoanalysis needs to be a cultural asset. Psychoanalysts need to build bridges, engage in partnerships, and emphasize the exciting method of philosophical probing of the human mind and the nature of human nature.

Surviving financial distress : the case of too many herbs and spices

Over 120 years ago Sir James Burns founded an organisation that is today, the international business group of Burns Philp and Company Ltd. The Group is widely known as a leading producer of yeast products and manufacturer of other bakery ingredients. Its ability to adapt to the ever-changing demands of business is widely recognised. During the late 1980’s however, after the group expanded into the herbs and spices industry its financial state deteriorated. Yet, arguably the Group had entered a market that complimented its then existing core-activities. This paper examines circumstances surrounding that venture into herbs and spices. It argues that the Group’s financial predicament, at that time, was exacerbated by the use of conventional accounting procedures. It illustrates that up-to-date market related financial details, in lieu of accounting book constructs, more aptly assist directors, managers, all stakeholders to conduct business and make informed economic decisions. This paper suggests that it is an entity’s current financial state of affairs, with regard to tangible market referents, that enables a firm’s strategic progress and facilitates proactive management; and in turn, assists in the sustainable development of business throughout the world.

The importance of intangible assets in initial public offerings

This paper follows Beatty and Ritter (1986), who argue that lower uncertainty about the value of an initial public offering (IPO) reduces the 'need' for the underpricing of an IPo. Australian IPOs often identify the existence of intangible assets such as goodwill, licenses, brand names, trademarks, patents and capitalized research and development costs in the prospectus. This paper analyses if IPOs identifying the existence of such intangible assets in the prospectus might reduce uncertainty about their valuation and hence allow a lower underpricing return. While the reporting of intangible assets such as goodwill and license costs in the prospectus are not significant ingredients in the level of underpricing, the identification and valuation of intangible assets such as brand names, trademarks, patents and capitalized research and development costs is significant in reducing the level of underpricing return. Our findings are also consistent with previous studies concluding that both the size of the new issue and the use of an underwriter are important in the level of underpricing return.

Agents and stream data mining: a new perspective

Many organizations struggle with the massive amount of data they collect. Today, data does more than serve as the ingredients for churning out statistical reports. They help support efficient operations in many organizations, and to some extent, data provide the competitive intelligence organizations need to survive in today's economy. Data mining can't always deliver timely and relevant results because data are constantly changing. However, stream-data processing might be more effective, judging by the Matrix project.

Australian sweet lupin flour addition reduces the glycaemic index of a white bread breakfast without affecting palatability in healthy human volunteers

The addition of some legume ingredients to bread has been associated with effects on glycaemic, insulinaemic and satiety responses that may be beneficial in controlling type 2 diabetes, cardiovascular disease and obesity. However, the effect of Australian sweet lupin (Lupinus angustifolius) flour (ASLF) is unknown. This investigation examined the effect of adding ASLF to standard white bread on post-meal glycaemic, insulinaemic and satiety responses and palatability in healthy subjects. Using a randomised, single-blind, cross-over design, 11 subjects consumed one breakfast of ASLF bread and two of standard white bread ≥ 7 days apart after fasting overnight. Each breakfast also included margarine, jam, and tea with milk and contained 50g available carbohydrate. On each test day, blood samples were taken after fasting, then several times over 2 hours post-prandially, and analysed for plasma glucose and serum insulin. Subjects rated breakfast palatability and perception of satiety, in the fasting state and over 3 hours post-prandially, after which food intake from an ad libitum buffet and for the rest of the day was recorded. Incremental areas under the curves for glucose, insulin and satiety, glycaemic index, insulinaemic index and satiety index were calculated. ASLF addition to the breakfast reduced its glycaemic index (mean ± SEM; ASLF bread breakfast = 74.0 ± 9.6. Standard white bread breakfast = 100, P=0.022), raised its insulinaemic index (ASLF bread breakfast = 127.7 ± 12.0. Standard white bread breakfast = 100, P=0.046), but did not affect palatability, satiety or food intake. ASLF addition resulted in a palatable breakfast; however, the potential benefits of the lowered glycaemic index may be eclipsed by the increased insulinaemic index.

Water-binding capacity and viscosity of Australian sweet lupin kernel fibre under in vitro conditions simulating the human upper gastrointestinal tract

There is currently little understanding of the physicochemical properties in the human gastrointestinal tract of Australian sweet lupin (Lupinus angustifolius) kernel fibre (LKF), a novel food ingredient with potential for the fibre enrichment of foods such as baked goods. Since physicochemical properties of dietary fibres have been related to beneficial physiological effects in vitro, this study compared water-binding capacity and viscosity of LKF with that of other fibres currently used for fibre-enrichment of baked goods, under in vitro conditions simulating the human upper gastrointestinal tract. At between 8.47 and 11.07g water/g dry solids, LKF exhibited water-binding capacities that were significantly higher (P<0.05) than soy fibre, pea hull fibre, cellulose and wheat fibre at all of the simulated gastrointestinal stages examined. Similarly, viscosity of LKF was significantly higher (P<0.05) than that of the other fibres at all simulated gastrointestinal stages. The relatively high water-binding capacity and viscosity of LKF identified in this study suggests that this novel fibre ingredient may elicit different and possibly more beneficial physiological effects in the upper human gastrointestinal tract than the conventional fibre ingredients currently used in fibre-enriched baked goods manufacture. We are now performing human studies to investigate the effect of LKF in the diet on health-related gastrointestinal events.

Effects of dietary lipid sources on flavour volatile compounds of brown trout (Salmo trutta L.) fillet

The high cost and unpredictable availability of fish meal and fish oil (FO) forced feed mill companies to look for alternative ingredients for aquafeeds. In this study, the effects of alternative dietary lipid sources [FO as control, canola oil (CO), oleine oil (OO), poultry fat (PF) and pork lard (PL)] in trout feed on flavour volatile compounds occurring in brown trout (Salmo trutta L.) fillet were evaluated after 70 days of feeding (rearing temperature 14.6°C). Total amounts of volatile compounds identified were higher for fillets of fish fed diets containing only FO as lipid sources. Total amount of alcohols and aldehydes of the fillets were linearly directly related to the percentage content of polyunsaturated fatty acids (PUFA) n-3 of brown trout flesh. The use of alternative dietary lipid sources, modifying the fillet fatty acids composition, affect the total amount of volatile compounds and, changing the relative amount of each volatile compound, affect the flavour of the fish flesh.

Tanshinone IIB, a primary active constituent from Salvia miltiorrhza, exhibits neuro-protective activity in experimentally stroked rats

Tanshinone IIB (TSB) is a major active constituent of the root of Salvia miltiorrhiza (Danshen) used in the treatment of acute stroke. Danshen extracts and TSB have shown marked neuron-protective effects in mouse studies but there is a lack of clinical evidence for the neuron-protective effects of Danshen and its active ingredients. This study investigated the neuron-protective effects of TSB in experimentally stroked rats. TSB at 5 and 25 mg/kg by intraperitoneal injection significantly reduced the focal infarct volume, cerebral histological damage and apoptosis in rats subjected to middle cerebral artery occlusion (MCAO) compared to MCAO rats receiving vehicle. This study demonstrated that TSB was effective in reducing stroke-induced brain damage and may represent a novel drug candidate for further development. Further mechanistic studies are needed for the neuron-protective activity of TSB.
