Potential sources of mouth drying in beverages fortified with dairy proteins: a comparison of casein and whey-rich ingredients

Oral nutritional supplement drinks (ONS) are beverages high in dairy proteins that are prescribed to individuals at risk of malnutrition. Consumption of ONS is poor in elderly care facilities, with patients commenting that the sensory attributes of these drinks reduce their enjoyment and willingness to consume. Mouth drying is an attribute of ONS found to build with repeated consumption, which may further limit liking of these products. This study investigated the sources of drying sensations by sequential profiling, with a trained sensory panel rating a range of model milk systems and ONS over repeated sips and during after-effects. Sequential profiling found that fortification of milk with both caseinate and whey protein concentrate significantly increased the perception of mouth drying over repeated consumption, increasing by between 35 and 85% over consumption of 40mL. Enrichment of ONS with either whey protein concentrate or milk protein concentrate to a total protein content of 8.7% (wt/wt) resulted in whey and casein levels of 4.3:4.4% and 1.7:7.0% respectively. The product higher in whey protein was substantially more mouth drying, implying that whey proteins may be the most important contributor to mouth drying in ONS. However, efforts to mask mouth drying of protein-fortified milk by increasing sweetness or fat level were unsuccessful at the levels tested. Increasing the viscosity of protein-fortified milk led to a small but significant reduction in mouth drying. However, this approach was not successful when tested within complete ONS. Further analysis is required into the mechanism of protein-derived mouth drying to mask negative sensations and improve the enjoyment and consumption of protein-rich ONS.

Investigation of the accuracy of historical irradiance products and interannual variability of solar irradiance using Met Office ground data

Met Office station data from 1980 to 2012 has been used to characterise the interannual variability of incident solar irradiance across the UK. The same data are used to evaluate four popular historical irradiance products to determine which are most suitable for use by the UK PV industry for site selection and system design. The study confirmed previous findings that interannual variability is typically 3–6% and weighted average probability of a particular percentage deviation from the mean at an average site in the UK was calculated. This weighted average showed that fewer than 2% of site-years could be expected to fall below 90% of the long-term site mean. The historical irradiance products were compared against Met Office station data from the input years of each product. This investigation has found that all products perform well. No products have a strong spatial trend. Meteonorm 7 is most conservative (MBE = −2.5%), CMSAF is most optimistic (MBE = +3.4%) and an average of all four products performs better than any one individual product (MBE = 0.3%)

Fast and Simple Nuclear Magnetic Resonance Method To Measure Conjugated Linoleic Acid in Beef

Conjugated linoleic acids (CLAs) are a group of linoleic acid isomers that are naturally found in food products originating from ruminants (meat and dairy). These acids have received special attention in recent years due to their potential human health benefits. Research efforts have been proposed to increase the CLA content in beef to improve public health. However, because there are more than 30 million beef cattle used each year by the American food industry, it will be necessary to ensure their content in a large number of samples. Therefore, it is important to have an inexpensive and rapid analytical method to measure CLA content in food products. Because gas chromatography (GC), a current popular method for measuring CLAs, is slow, this paper describes a nuclear magnetic resonance spectroscopy ((1)H NMR) method that is potentially >10 times faster than the GC method. Analyses show a correlation coefficient of 0.97, indicating the capacity of NMR to quantify the CLA content in beef samples. Furthermore, the method proposed herein is simple and does not require sophisticated sample preparation.

Entry, re-location and growth in the Swedish wholesale trade industry

Wholesale trade has an intermediate position between manufacturing and retail in the distributional channel. In modern economies, consumers buy few, if any, products directly from manufacture or producer. Instead, it is a wholesaler, who is in direct contact with producers, buying goods in larger quantities and selling them in smaller quantities to retailers. Traditionally, the main function of a wholesaler has been to push goods along the distributional channel from producer to retailer, or other nonend user. However, the function of wholesalers usually goes beyond the process of the physical distribution of goods. Wholesalers also arrange storage, perform market analyses, promote trade or provide technical support to consumers (Riemers 1998). The existence of wholesalers (and other intermediaries) in the distributional channel is based on the effective and efficient performance of distribution services, that are needed by producers and other members of the supply chain. Producers usually do not enjoy the economies of scale that they have in production, when it comes to providing distributional services (Rosenbloom 2007) and this creates a space for wholesalers or other intermediaries. Even though recent developments in the distributional channel indicate that traditional wholesaling activities now also compete with other supply chain organizations, wholesaling still remains an important activity in many economies (Quinn and Sparks, 2007). In 2010, the Swedish wholesale trade sector consisted of approximately 46.000 firms and generated an annual turnover of 1 300 billion SEK (Företagsstatistiken, Statistics Sweden). In terms of turnover, wholesaling accounts for 20% of the gross domestic product and is thereby the third largest industry. This is behind manufacturing and a composite group of firms in other sectors of the service industry but ahead of retailing. This indicates that the wholesale trade sector is an important part of the Swedish economy. The position of wholesaling is further reinforced when measuring productivity growth. Measured in terms of value added per employee, wholesaling experienced the largest productivity growth of all industries in the Swedish economy during the years 2000 through 2010. The fact that wholesale trade is one of the important parts of a modern economy, and the positive development of the Swedish wholesale trade sector in recent decades, leads to several questions related to industry dynamics. The three topics that will be examined in this thesis are firm entry, firm relocation and firm growth. The main question to be answered by this thesis is what factors influence new firm formation, firm relocation and firm growth in the Swedish wholesale trade sector?

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.

Globalisation and manufacturing strategy in the TCF industry

Purpose – The textiles, clothing, and footwear (TCF) industry has struggled in Australia since the government commenced dismantling tariffs. By sourcing from Asia, middlemen undercut established suppliers, and retail chains set benchmark low prices with their imported “house” labels. The policy-makers predicted that local producers would become more efficient, and export to make up for lost sales, but the media paints a picture of rising imports, retrenchments, and factory closures. The research objective was to discover what strategies the survivors (actually) employ in adapting to the pressures of globalisation.

Design/methodology/approach – More than 30 companies were involved in the study, ranging from small family businesses to subsidiaries of big multinationals. Each case study was based on an interview with a senior executive, normally followed by a plant tour. This methodology suits a fresh topic, as it avoids preconceptions and imposes no bounds.

Findings – Results show that the policy change was based on “pie in the sky” forecasts. Increasingly, TCF production is transferred to cheap offshore locations, generally via subcontracting plus the “badging” of foreign designs. To survive, local factories should focus on quality and customer service, preferably in niche markets (like uniforms), or for specific customer groups, and develop technologically advanced products. A move down the supply chain into retailing can also assist. Large multinational corporations that engage in foreign direct investment dominate the management literature.

Originality/value – This paper presents a different perspective, neglected in international operations management, whereby domestically oriented businesses attempt to defend themselves against the adverse consequences of globalisation.

Food industry awareness of consumers` plant food beliefs

Abstract: Purpose – The aims of this study were to examine farmers' and food processors' alignment with consumers' views about plant foods and their intentions to produce plant foods. Design/methodology/approach – Data on plant food beliefs were collected from mail surveys of farmers, food processing businesses and random population samples of adults in Victoria, Australia. Findings – There were strong differences between consumers' beliefs and farmers' and food processors' perceptions of consumers' beliefs. For example, a higher proportion of farmers and processors believed that consumers would eat more plant foods if more convenience-oriented plant-based meals were available than consumers themselves agreed. Farmers appeared to be more aware of or aligned with consumers' beliefs than were processors. One- and two-thirds of farmers and processors respectively were planning to grow or process more plant foods, which bodes well for the availability of plant and plant-based foods. Research limitations/implications – Study limitations include the small food industry sample sizes and possible response bias, although analysis suggests the latter was low. Future research could survey a larger sample of food industry representatives, including those from other sectors (e.g. retailers). Practical implications – Education of consumers and industry groups on plant foods and better lines of communication from consumer to processor to farmer, are required. Originality/value – To the authors' knowledge, this is the first study to examine farmers' and food processors' awareness of consumers' beliefs about plant foods. This issue is important for those involved with the production and marketing of plant foods or with food, farming and health policy.

Assessment of embodied energy analysis methods for the Australian construction industry

Environmental assessment of buildings typically focuses on operational energy consumption in an attempt to minimise building energy consumption. Whilst the operation of Australian buildings accounts for around 20% of total energy consumption nationally, the energy embodied in these buildings represents up to 20 times their annual operational energy. Many previous studies, now shown to be incomplete in system boundary or unreliable, have provided much lower values for the embodied energy of buildings and their products. Many of these studies have used traditional embodied energy analysis methods, such as process analysis and input-output (1-0) analysis. More recently, hybrid embodied energy analysis methods have been developed, combining these two traditional methods. These hybrid methods need to be compared and validated, as these too have been considered to have several limitations. This paper aims to evaluate a recently developed hybrid method for the embodied energy analysis of the Australian construction industry, relative to traditional methods. Recent improvements to this hybrid method include the use of more recent 1-0 data and th.fl inclusion of capital energy data. These significant systemic changes mean that a previous assessment of the methods needs to be reviewed. It was found that the incompleteness associated with process analysis has increased from 49% to 87%. These findings suggest that current best-practice methods of embodied energy analysis are sufficiently accurate for most typical applications. This finding is strengthened by recent improvements to the 1-0 model.

Investigation of the value chain for creative products : a phenomenological study of the perceptions of music intermediaries

During the past decade, innovative digital technology and Internet marketplaces have created a variety of 'phenomena' of businesses, media and institutions considered to be important interaction channels in the music industry, along with an influx of Peer-to-Peer services such as Napster, and Kazaa shifting the business models of major music labels and distributors. Considering the Australian Music Association reported an annual retail turnover of approximately $300 million in 1992 and later in 1999, an increase in figures reported at $396.8 million with the inclusion of music DVD sales, the notion of value-adding to a music product emerges as a profitable venture at each length of the music industry's value chain. In spite of this, Australian studies have often overlooked the underlying perceptions, fears and ideas of those working within the value chain, especially regarding the impact of new technology on their roles. This paper identifies the perceptions of various intermediaries within the Australian Music Industry, identifying common themes and viewpoints amongst the study's participants. Consequently, the paper concluded that the perception of value in the music industry is somewhat influenced by a variety of factors, including music knowledge, communication and dependence on intermediaries to name a few. Common themes were revealed throughout the study include the perception of competitive advantage, new opportunities from new technology and the notion of defining a gimmick versus Value-Adding emerged as indicative of adding value from the study participants.

The nature and development of the general insurance industry in Australia to 1973

The development of the insurance industry in Australia in the twentieth century was fundamentally shaped by a collusive code of conduct called the tariff. This arrangement, established to overcome problems of uncertainty, initially benefited both tariff and non-tariff firms by enhancing market stability. It also reduced competition. The collusive agreements gradually broke down, however, as new entrants and products entered the market in the 1950s. Self-regulation gradually gave way as the 'rules of the game' changed. The result was a period of instability before new competitive practices, and more direct and specific regulatory requirements emerged in the 1970s.

The global biopharma industry and the rise of Indian drug multinationals: implication for Australian generics policy

This article provides a synopsis of the new dynamics of the global biopharma industry. The emergence of global generics companies with capabilities approximating those of 'big pharma' has accelerated the blurring of boundaries between the innovator and generics sectors. Biotechnology-based products form a large and growing segment of prescription drug markets and regulatory pathways for biogenerics are imminent. Indian biopharma multinationals with large-scale efficient manufacturing plants and growing R&D capabilities are now major suppliers of Active Pharmaceutical Ingredients (APIs) and generic drugs across both developed and developing countries. In response to generic competition, innovator companies employ a range of life cycle management techniques, including the launch of 'authorised generics'. The generics segment in Australia will see high growth rates in coming years but the prospect for local manufacturing is bleak. The availability of cheap generics in international markets has put pressure on Pharmaceutical Benefits Scheme (PBS) pricing arrangements, and a new policy direction was announced in November 2006. Lower generics prices will have a negative impact on some incumbent suppliers but industrial renewal policies for the medicines industry in Australia are better focused on higher value R&D activities and niche manufacturing of sophisticated products.

Efficiency measurement of Australian dairy farms: national and regional performance

In this paper we use Data Envelopment Analysis (DEA) to estimate technical efficiency for a sample of 1742 Australian dairy farms. Bearing in mind data limitations we find that average technical efficiency is 59 per cent, but there are significant regional differences. These results reflect differences in State level milk marketing arrangements in place before dairy deregulation in July 2000 providing an ex post explanation for the changing composition of dairy farms in Australia. We also examine two important technical aspects of DEA implementation. First, how changes in model input specification alter the relative performance of farms. Second, we employ a simple bootstrap procedure to show how changes in sample size affects estimates of technical efficiency. These results have simple but important implications for the use of DEA as an industry-benchmarking tool.

Where did all these books come from? The Publishing Industry and American Intellectual Life

The American book publishing industry shapes the character of American intellectual life. While the newspaper and television industries have been accused of and investigated for bias and lowering America’s intellectual standards, book publishing has gone largely unexamined by scholars. The existing studies of the publishing industry have focused on finance, procedure and history. “There are few ‘theories’ of publishing – efforts to understand the ‘whys’ as well as the ‘hows.’ Few scholarly scientists have devoted significant scholarly attention to publishing” (Altbach and Hoshino, xiii). There are many possible reasons for this lacuna. First, there is a perception that books have always been around, that they are an “old” technology and therefore they don’t appear to have had as much of an impact on our society as television and other media (which were developed quickly and suddenly) seem to have had (Altbach and Hoshino, xiv). Also, despite books’ present and past popularity, television, radio, and now the internet reach more people more easily, and are therefore more topical points of study and observation. In studying the effects of mass media on everyday American life, television and the internet may be the most logical points of study. Regarding public intellectual life however, books play a much more important role. Public intellectual life has always been associated with independent thinkers publishing their work for the masses. For this reason, this I focus on trade publishing. Trade publishing produces fiction and non-fiction works for the general reading public, as opposed to technical manuals, textbooks, and other fiction and nonfiction books targeted to small and specific audiences. Although, quantitatively speaking, “the largest part of book publishing business is embodied in that great complex of companies and activities producing educational, business, scientific, technical, and reference books and materials,” (Tebbel 1987, 439) the trade industry publishes most of the books that most people read. It is the most public segment of the industry, and the most likely place to find public intellectualism. Trade publishing is not only the most public segment of the industry, but it is also the most susceptible to corruption and lowered intellectual standards. Unlike specialty publishing, which caters to a specific, known segment of society, trade publishers must compete with countless other publications, as well as with other forms of media, for the patronage of the general public. As John Tebbel (author of a widely referenced history of the publishing industry) puts it, “The textbook, scientific, or technical book is subjected to much more rigorous scrutiny by buyers and users, and in an intensively competitive market inferior products are quickly lost" (Tebbel 1987, xiv). Since the standards for trade publishing are not nearly as specific – trade books simply need to catch the attention of a significant number of readers, they don’t have to measure up to a given level of quality – the quality of trade books is much more variable. And yet, a successful trade publication can have a much greater impact on society than the most rigorously researched and edited textbook or scholarly study.
