This study aims to investigate the influence of soy protein isolate hydrolysates (SPIH) obtained using 4 h hydrolysis under 200 MPa on proximate composition, cooking loss, textural properties, color, water distribution, microstructure, thiobarbituric acid reactive substance (TBARS) value and carbonyl and sulfhydryl contents of emulsion sausages.

Sausages with SPIHs at four concentrations (0, 1.0, 2.0 and 3.0%) were prepared, and the sausage with 0.01% butylated hydroxyanisole (BHA) was used as a positive control. Some sausages were selected for the analyses of quality characteristics and microcosmic properties. Other sausages were stored under 4 °C for 0, 7, 14, 21 and 28 days to investigate the oxidative stability.

The addition of SPIHs at various levels (0–3.0%) or 0.01% BHA did not affect the proximate composition (protein, fat and ash) of emulsion sausages. The addition of 2.0% SPIH decreased cooking loss and increased moisture content, hardness, springiness, chewiness, resilience and L* value, compared to the sausages without SPIH and with 0.01% BHA (p < 0.05). Furthermore, low-field nuclear magnetic resonance results suggested that sausages with 2.0% SPIH had the shortest T2 relaxation time. In addition, 2.0% SPIH and 0.01% BHA could inhibit the oxidation of emulsion sausages when compared with the sample without SPIH (p < 0.05). Moreover, there were no differences between sausages with 2.0% SPIH and 0.01% BHA (p > 0.05).

These findings confirmed that the 2.0% SPIH obtained under 200 MPa can be used as a natural additive to improve quality properties and antioxidant potential of emulsion sausages during storage.

This paper aims to develop a good quality pork sandwich spread incorporated with different levels of antioxidant mixture [butylated hydroxyanisole (BHA) + butylated hydroxytoluene (BHT); 1:1] and to assess sensory, physico-chemical and microbiological properties of frozen product during storage.

Three levels of antioxidant mixture (BHA + BHT; 1:1) i.e. 100, 200 and 400 ppm were tried, and the product was compared for physico-chemical, microbiological and sensory properties along with the control during frozen storage (−18 ± 1°C).

pH and water activity decreased significantly (p < 0.05), whereas water holding capacity, 2-thiobarbituric acid reacting substances value, total plate count and psychrotrophic count increased significantly (p < 0.05) during storage period. No coliform, yeast and molds were detected throughout the study period. There was non-significant (p < 0.05) effect of antioxidant treatment on the scores of colour, texture, juiciness, adhesion ability and spreadability, but scores for flavour and overall acceptability significantly (p < 0.05) increased.

Pork sandwich spread is envisaged to help in providing nutrition to a large section of needy population and will add a new dimension to the convenience foods.

Antioxidant mixture (BHA + BHT, 1:1) treatment improved the sensory and microbiological properties of pork sandwich spread at frozen storage (−18 ± 1°C). At the end of storage period (60 days), the pork sandwich spread was found safe for human consumption. Hence, BHA and BHT antioxidant mixture could be used to improve quality attributes of meat products during storage.

A study was conducted to determine the antioxidative properties of roselle (Hibiscus sabdariffa L.) methanol extract by monitoring the formation of diene‐conjugated compounds and thiobarbituric acid reactive substances (TBARS) in linoleic acid model system. The properties were compared to those of butylated hydroxy‐anisole (BHA) and α‐tocopherol. Results indicated that the roselle extract showed stronger antioxidant properties than BHA or α‐tocopherol. A total of 200 parts per million (ppm) of the extract inhibited more than 85 per cent of diene‐conjugated compounds after seven days of incubation at 40^○C. The total phenolic compound was found to be 2.96mg/g calyx as gallic acid equivalent. This indicates that roselle is a good source of natural antioxidants which may protect the body from damage by free radicals and lipid peroxidation. The protective effect is probably through the action of highly bioavailable ascorbic acid, β‐carotene and phenolic compounds, especially the anthocyanins.

Diversity in board composition, in particular the underrepresentation of women, has received significant attention over recent years in many sectors, including sport. Within British horseracing, whilst some maintain that the industry operates consistently as a meritocracy, others argue that women remain underrepresented at senior levels. This chapter explores arguments for increasing the number of women on boards and governing bodies, covering the business case and the ways that ‘substantive’ and ‘descriptive’ representation might embed sustained structural change. It draws on a research study which identified a lack of gender balance in many of horseracing's governing structures. Though emerging from its history as ‘mainly a male world’, structural barriers to impede women's progress remained evident. Women were found to experience a lack of role models, limited access to the mentoring and networking they needed to navigate the industry, and gender stereotyping. The response to these findings resulted in an industry plan for change, instigated by the British Horseracing Authority. This included the introduction of a specialist advisory body, targets for increased women's representation, diversity data collection and analysis, and support for role model and mentoring initiatives. These activities are reviewed herein using the organisational theoretical approaches of ‘institutional theory’, which identifies external pressures to conform to accepted business practice; ‘resource dependency theory’ and the role of inter-organisational arrangements; and ‘network theory’ analysing interdependencies with other organisations. I conclude by evaluating the potential impact of this work for achieving more gender-balanced governance.

This chapter addresses the related questions of how to assess housing redevelopment and what constitutes a successful redevelopment project, based on the HOPE VI transformation of Boston’s Orchard Park from one of the city’s most notorious, crime-ridden public housing projects into a mixed-income community that remained overwhelmingly composed of low-income residents.

The analysis is based on a unique set of interviews with a sample of residents before and after housing redevelopment occurred. In addition, we draw upon interviews with housing authority staff, official agency file documents, and archival materials.

We find increased residential satisfaction after redevelopment but lingering concerns about safety and security despite marked declines in crime. Although the redevelopment process displaced some households, residents attributed improvements in living conditions to changes in tenant composition prompted by the housing transformation.

The results suggest an alternative model of public housing redevelopment that accommodates a majority of poor, subsidized households with some displacement. Still, loss of housing units, tenant selection, and social problems complicate notions of successful redevelopment.

This chapter contributes to the literature by showing how some low-income families may benefit from housing displacement induced by the redevelopment process. We analyze an overlooked but frequently implemented approach to housing redevelopment under the HOPE VI program to keep the majority of redeveloped units for low-income residents. It is the only study of which we are aware that has collected public housing resident opinions both before and after HOPE VI redevelopment occurred.

The degradation of a town’s traditional architectural settings is a prominent issue in the historic towns that possess a rich heritage and legacies of architectural character in its urban fabric that have developed over the course of its evolution. Resident participation in built-heritage conservation can be explained in terms of deliberate acts. Thus, this study aims to analyse the attitudes of residents on the conservation of built heritage (ARCBH) in the historic town of Kanchipuram.

The historic temple town of Kanchipuram has been surveyed and focused in this study. A questionnaire was designed to investigate the ARCBH in Kanchipuram. Data were collected and analysed with the help of structural equation modelling and AMOS software. A structural equation model was developed, and hypotheses were framed for an empirical study.

The findings indicate that the ARCBH has an effective relationship with practical issues that occur in traditional architecture, built-heritage attachment and an awareness of existing heritage schemes.

The study results indicate that considering resident attitude and attachment is important. In addition, the results provide useful insights for formulating practical measures relevant to built-heritage conservation.

There has been no attempt to come up with practical implications from the attitudes of residents on the conservation of built-heritage in the historic temple towns of Tamil Nadu, India.

Natural selection—survival of the fittest—is as old as life itself. Applied genetics which is purposeful in contrast to natural selection also has a long history, particularly in agriculture; it has received impetus from the more exacting demands of the food industry for animal breeds with higher lean : fat and meat : bone ratios, for crops resistant to the teeming world of parasites. Capturing the exquisite scent, the colours and form beautiful of a rose is in effect applied genetics and it has even been applied to man. For example, Frederick the Great, Emperor of Prussia, to maintain a supply of very tall men for his guards—his Prussian Guards averaged seven feet in height—ordered them to marry very tall women to produce offspring carrying the genes of great height. In recent times, however, research and experiment in genetic control, more in the nature of active interference with genetic composition, has developed sufficiently to begin yielding results. It is self‐evident that in the field of micro‐organisms, active interference or manipulations will produce greater knowledge and understanding of the gene actions than in any other field or by any other techniques. The phenomenon of “transferred drug resistance”, the multi‐factorial resistance, of a chemical nature, transferred from one species of micro‐organisms to another, from animal to human pathogens, its role in mainly intestinal pathology and the serious hazards which have arisen from it; all this has led to an intensive study of plasmids and their mode of transmission. The work of the Agricultural Research Council's biologists (reported elsewhere in this issue) in relation to nitrogen‐fixing genes and transfer from one organism able to fix nitrogen to another not previously having this ability, illustrates the extreme importance of this new field. Disease susceptibility, the inhibition of invasiveness which can be acquired by relatively “silent” micro‐organisms, a better understanding of virulence and the possible “disarming” of organisms, particularly those of particular virulence to vulnerable groups. Perhaps this is looking for too much too soon, but Escherichia coli would seem to offer more scope for genetic experiments than most; it has serotypes of much variability and viability; and its life and labours in the human intestine have assumed considerable importance in recent years. The virulence of a few of its serotypes constitute an important field in food epidemiology. Their capacity to transfer plasmids—anent transfer of drug resistance— to strains of other organisms resident in the intestines, emphasizes the need for close study, with safeguards.

Traces the economic development of Thailand since 1945, referring to relevant research, and analyses the reasons why it was the first Southeast Asian country to collapse in the 1997 economic crisis: large current account deficits, excessive external debt, a collapse in the property sector, exchange rate mismanagement and political instability. Considers its future prospects and shows statistics on economic growth and inflation for the world as a whole and various countries and groups within it.

Statements by Lord Denning, M.R., vividly describing the impact of European Community Legislation are increasingly being used by lawyers and others to express their concern for its effect not only on our legal system but on other sectors of our society, changes which all must accept and to which they must adapt. A popular saying of the noble Lord is “The Treaty is like an incoming tide. It flows into the estuaries and up the rivers. It cannot be held back”. The impact has more recently become impressive in food law but probably less so than in commerce or industry, with scarcely any sector left unmolested. Most of the EEC Directives have been implemented by regulations made under the appropriate sections of the Food and Drugs Act, 1955 and the 1956 Act for Scotland, but regulations proposed for Materials and Articles in Contact with Food (reviewed elsewhere in this issue) will be implemented by use of Section 2 (2) of the European Communities Act, 1972, which because it applies to the whole of the United Kingdom, will not require separate regulations for England and Wales, Scotland and Northern Ireland. This is the first time that a food regulation has been made under this statute. S.2 (2) authorises any designated Minister or Department to make regulations as well as Her Majesty Orders in Council for implementing any Community obligation, enabling any right by virtue of the Treaties (of Rome) to be excercised. The authority extends to all forms of subordinate legislation—orders, rules, regulations or other instruments and cannot fail to be of considerable importance in all fields including food law.
