Abstract
Purpose
This paper focuses on the effect of different pretreatments on some properties of tigernut, an underutilized crop in Nigeria with the aim of widening its utilization in the country.
Design/methodology/approach
Tigernuts were subjected to various pretreatments such as fermentation, germination, pregelatinization and roasting before drying at 50 ± 2 ○C for 48 h in locally fabricated cabinet drier and milling in commercial plate mill to produce meal which passed through 30 mm pore‐sized sieve. Pretreated and untreated tigernut meals were analyzed using methods reported in the literature for chemical composition, physicochemical and functional properties.
Findings
Protein content of the meals ranged from 2.79 ± 0.01 to 3.65 ± 0.02 per cent with sample from fermented tigernut having the highest value and those from roasted ones having the least value. There were slight variations in the crude fat, fiber and ash contents of the resultant meals after pretreatment. There were 10 and 14 per cent enhancement in the ascorbic acid contents of fermented and germinated meals respectively. Titratable acidity, pH and water absorption capacity were affected by pretreatment in this study. Bulk density varied slightly after pretreatment. Germination, roasting and pregelatinization resulted in marked decrease in peak viscosity of the samples. The emulsion capacity ranged from 48.4 to 56 per cent with the untreated sample having the highest value and meals from roasted sample had the least value. Foaming capacity was improved by the pretreatments with the exception of roasting which reduced it from 2.15 to 1.18 per cent.
Originality/value
The paper has demonstrated the effect of pretreatments on tigernut meals and its potential applications in various food formulation and development, e.g. weaning foods, baked goods, beverage products, etc.

Abstract
Purpose
This paper aims to focus on the prospects of incorporating a non‐thermal process (high intensity electric field pulses, HELP) into food processing and preservation methods in developing countries. Besides, it is to create awareness to food processors and motivate researchers in developing countries to generate more data on the technology.
Design/methodology/approach
This is based on the review of the various successful applications of HELP process in inactivation of micro‐organisms for the purpose of preservation. The adaptability of the process to plant food processing was also reviewed. Potential areas of application in developing countries were also highlighted and discussed.
Findings
The present findings reveal possible applications of HELP to food processing in developing countries such as fermentation, fruit and vegetable processing, and dehydration of tropical food.
Originality/value
The paper has indicated that the poor energy system in developing countries has made drying and fermentation techniques appropriate methods of food processing. Therefore, HELP technology offers good potentials for both food processing and preservation and as adjunct to other processes such as fermentation and drying.

Abstract
Purpose
This paper sets out to focus on the utilization of the locally available raw material to develop an acceptable and high quality non‐alcoholic beverage in Nigeria.
Design/methodology/approach
Maize‐based non‐alcoholic beverages were produced from either plain maize powder or combinations of maize powder and mango or soybean flour. Plain and fruit or soy‐ fortified maize powders were analyzed using standard methods for chemical composition, while total solid, sediment height, pH, titratable acidity, storage stability and microbial load were determined on the formulated beverage products. Taste panel evaluation was conducted to evaluate the acceptability of the products.
Findings
While the protein, fat and ash contents of plain maize powder were 5.69, 5.95 and 0.35 per cent respectively, there was minimal enhancement with fruit addition. However, with 10 per cent soybean addition significant improvement over the unfortified sample in protein (14.62 per cent), fat (10.64 per cent) and ash (0.96 per cent) was obtained. Sediment height was found to be higher for beverage with sour water and least for soy‐fortified beverage. Titratable acidity of beverage samples was found to be 0.022, 0.018, 0.054 and 0.306 per cent (per cent lactic acid) for plain, fruit‐flavoured, soy‐fortified and soured beverages respectively. Variation in titratable acidity was observed depending on the product and storage condition. Sensory evaluation result for beverage prepared with sour water (0–100 per cent) revealed preference for soured beverage with 80 per cent sour water. Also, fruit‐flavoured sample ranked highest in preference followed closely by the plain beverage, while soy‐fortified sample was the least acceptable.
Originality/value
The paper has demonstrated the feasibility of developing acceptable beverage samples from sour water (a by‐product of Ogi usually regarded as waste) and combinations of either maize powder and mango or soybean flour.

This study aimed at the potential use of ginger‐flavoured soy‐cassava flour to produce high‐protein biscuits.
Abstract
Purpose
This study aimed at the potential use of ginger‐flavoured soy‐cassava flour to produce high‐protein biscuits.
Design/methodology/approach
Preparation of biscuit was done using soy‐cassava flour blends (0:100, 20:80, 30:70 and 40:60 w/w). Biscuit was also prepared from 100 per cent wheat flour to serve as control.
Findings
Chemical analysis indicated that the substitution of soy flour into cassava flour augmented the nutrient content of the biscuit, which indicates a good potential for meeting the nutrient requirements of school children. The use of ginger powder as flavouring agent effectively masked the beany flavour that is normally associated with soybean products. A sensory evaluation also confirmed good aroma and positive acceptability.
Originality/value
The findings in this study confirms the endless possibilities of protein enrichment of cassava flour for the production of biscuits as a potentially effective strategy for enhancing protein‐energy balance in children, particularly in developing countries. The value of this study lies in its potential as a product development strategy in combating protein‐energy malnutrition, thereby promoting good health, labour productivity and mental development.

Abstract
Introduces a special issue on globalization and the welfare state. Asserts that economic globalization constrains national economic and social policy far more now than ever before, although the level of international trade has not increased that much compared to levels at the beginning of this century. Talks about the political consequences of economic globalization, particularly welfare state retrenchment in the advanced capitalist world. Outlines the papers included in this issue – comparing welfare system changes in Sweden, the UK and the USA; urban bias in state policy‐making in Mexico; and the developing of the Israeli welfare state. Concludes that economic globalization has a limited effect in shaping social welfare policy in advanced capitalist countries; nevertheless, recommends further research into which aspects of economic globalization shape social welfare policy.

Abstract
Attempts to establish the extent to which the use of computers in Australia’s Department of Social Security (DSS) has facilitated changes in social security policy and its administration. Bases findings on case studies relating to two new DSS policies, supplemented with documentary evidence. Identifies that computers are used in the DSS for six main purposes ‐ administering, automating, protecting, monitoring and evaluating policy, as well as for modelling future policy options. Identifies that, instead of increasing efficiency in administration, computers have simply increased productivity by enabling administrative practices to be extended into new areas; observes an emerging computer‐dependent culture dominated by quantitative (rather than qualitative) practices. Establishes that the flexibility offered by computer technology has also contributed to the introduction of more complex social security policies. Concludes that computer technology has contributed to the formulation and administration of social security policies.

Abstract
Fieldwork is one of the hallmarks of anthropology. Almost all students of anthropology have geographical and cultural specializations, ranging from a small group to a nation. Their interest areas are often identified or marked by real or putative boundaries; and it is within these boundaries that anthropologists have “founded” their own villages and tribes — “my village”, “my tribe.”

Abstract
Recounts Rockefeller philanthropy and the role it has played in shaping the development of medicine in the USA and elsewhere. Questions why social scientific research was not included in Rockefeller philanthropy in its formative stages. Investigates the role one Frederick T. Gates played in Rockefeller philanthropy and, particularly, his opposition to the creation of an institute of economic research. Sketches a biography of Gates, covering his professional career and the development of the philosophical views he held. Explores his approach to wholesale giving and scientific philanthropy as he gained more and more influence over Rockefeller’s business interests. Mentions William Lyon Mackenzie King (who later became Prime Minister of Canada) and his role within the Rockefeller philanthropic set‐up – to investigate labour relations – as a key factor in later obtaining support from the Rockefeller Foundation for social scientific research.

Abstract
Examines the extent to which social policy adopted by the colonial government in Hong Kong (prior to its hand‐over China in 1997) has set the agenda for the government of the newly formed Special Administrative Region (SAR). Chronicles the historical development of social policy in Hong Kong since the inception of the colonial government in 1842; identifies that, with the exception of a short‐lived period of expansionism (stimulated by social unrest in the mid‐1960’s) social welfare provision appears to have been low on the government’s agenda and incremental in nature ‐ the emphasis being on economic growth, rather than public spending on welfare programmes. Examines the strengths and weaknesses of this incremental approach; outlines the commitment of the SAR government to the market economy and its proposals for a modest increase in welfare provision, essentially building on the legacy left behind by the colonial government.
