Around the world, cereals are stapled foods and good sources of vitamins A, B, and E. As cereals are inexpensive and consumed in large quantities, attempts are being made to enrich cereals using fortification and biofortification in order to address vitamin deficiency disorders in a vulnerable population. The processing and cooking of cereals significantly affect vitamin content. Depending on grain structure, milling can substantially reduce vitamin content, while cooking methods can significantly impact vitamin retention and bioaccessibility. Pressure cooking has been reported to result in large vitamin losses, whereas minimal vitamin loss was observed following boiling. The fortification of cereal flour with vitamins B1, B2, B3, and B9, which are commonly deficient, has been recommended; and in addition, region-specific fortification using either synthetic or biological vitamins has been suggested. Biofortification is a relatively new concept and has been explored as a method to generate vitamin-rich crops. Once developed, biofortified crops can be utilized for several years. A recent cereal biofortification success story is the enrichment of maize with provitamin A carotenoids.

Humans need vitamin A and obtain essential vitamin A by conversion of plant foods rich in provitamin A and/or absorption of preformed vitamin A from foods of animal origin. The determination of the vitamin A value of plant foods rich in provitamin A is important but has challenges. The aim of this paper is to review the progress over last 80 years following the discovery on the conversion of β-carotene to vitamin A and the various techniques including stable isotope technologies that have been developed to determine vitamin A values of plant provitamin A (mainly β-carotene). These include applications from using radioactive β-carotene and vitamin A, depletion-repletion with vitamin A and β-carotene, and measuring postprandial chylomicron fractions after feeding a β-carotene rich diet, to using stable isotopes as tracers to follow the absorption and conversion of plant food provitamin A carotenoids (mainly β-carotene) in humans. These approaches have greatly promoted our understanding of the absorption and conversion of β-carotene to vitamin A. Stable isotope labeled plant foods are useful for determining the overall bioavailability of provitamin A carotenoids from specific foods. Locally obtained plant foods can provide vitamin A and prevent deficiency of vitamin A, a remaining worldwide concern.

Insight Into

AB InBev is today’s uncontested world leader of the beer market. It represents over 20 per cent of global beer sales, with more than 450 million hectolitres a year flowing all around the world. Its Belgian predecessor, Interbrew, was a success story stemming from the 1971 secret merger of the country’s two leading brewers: Artois and Piedboeuf. Based on first-hand material originating from company and private archives as well as interviews with managers and key family actors, this is the first study to explore the history of the company through the nineteenth and twentieth centuries.The story starts in the mid-nineteenth century with the scientific breakthroughs that revolutionized the beer industry and allowed both Artois and Piedboeuf to prosper in a local environment. Instrumental in this respect were the respective families and their successive heirs in stabilizing and developing their firms. Despite the intense difficulties of two world wars in the decades to follow, they emerged stronger than ever and through the 1960s became undisputed leaders in the national market. Then, in an unprecedented move, Artois and Piedboeuf secretly merged their shareholding in 1971, though keeping their operations separate until 1987 when they openly and operationally merged to become Interbrew. Throughout their histories Artois, Piedboeuf, and their successor companies have kept a controlling family ownership. This book provides a unique insight into both the complex history of these three family breweries and their path to becoming a prominent global company, and the growth and consolidation of the beer market through the nineteenth and twentieth centuries.

Five years ago, women in Africa moved to the center stage of the continent. The U.N. Decade for Women Conference held in Nairobi brought together women from all over the world to exchange ideas and discuss future strategies. African women turned out for the meeting in force. Women representing governments, non-governmental organizations (NGOs) and grass-roots women's clubs converged on Nairobi to tell their story to other women in the common struggle for equality, justice and peace.

Provitamin A Carotenoids

<p>Changes in the concentrations and retention levels of total and individual provitamin A carotenoids (pVACs) during ripening and local processing of the four most popular <em>Musa</em> cultivars of Eastern Democratic Republic of Congo were established through HPLC analysis. The predominant pVACs were all <em>trans</em> ?- and ?-carotene, together constituting about 90% of total pVACs content in raw and processed <em>Musa</em> fruit pulp. The proportion of ?- and ?-carotene was not significantly different in the tested East African Highland Bananas (AAA-EAHB) (‘Nshikazi’ and ‘Vulambya’); in the plantains (‘Musilongo’ and ‘Musheba’), proportion of ?-carotene was almost twice that of ?-carotene. An increase in total pVACs was observed during ripening, with highest levels at ripening stage 3 in all four cultivars. Total pVACs values were as high as 1081µg/100gfw in ‘Vulambya’ and 1819µg/100gfw in ‘Musilongo’. Boiling of the AAA-EAHB and AAB-Plantains resulted to retention of between 40-90% and &gt;95% respectively. Plantains deep-fried in fully-refined palm oil and crude red palm oil for 2 minutes did not seem to lose any pVACs, the levels of total pVACs observed after frying were 100% of what was observed when the fruit was raw. Retinol Activity Equivalents (RAE), in boiled products varied between 22.3 and 173 RAEµg/100gfw, whereas deep fried products had &gt;190 RAEµg/100g edible portion. These results show that the tested AAA-EAHBs and the plantains could meet at least 14% and 30 % of Vitamin A recommended dietary intakes respectively. The findings can therefore guide consumer consumption patterns to maximize vitamin A intake for improved health in these regions and also direct researchers in the selection of <em>Musa</em> cultivars to be incorporated within existing farming systems in the fight against vitamin A deficiency (VAD).</p>

The Sunday newspaper is an often-neglected success story of the twentieth century news media landscape. The popularity and profitability of Sunday papers grew throughout the century to establish themselves as flagships of cultural and commercial trends and an essential complement to most national daily productions. On account of their production cycle, Sunday newspapers were always able to do things that the daily press with its punishing routines and pressure of deadlines were never able to achieve. Mapped onto the characteristic social class and politically stratified perspectives of British and Irish newspaper reading publics, the Sunday newspaper became a prominent vehicle for the experiments in layout and content after the full computerization of newspapers in the mid-1980s; lifestyle, commentary, colour photography all were pioneered in this format. The range of geographical variants of the Sunday newspaper are also considered from the regional Sunday Sun published in Newcastle from 1919 to the Irish Sunday Independent and Scottish Sunday Post to the migration of English titles across Britain into Ireland with increasing national specialization in their content and appeal. The chapter also considers the varying reasons for the failure of high-profile Sunday papers such as the Sunday Correspondent and the News of the World.

There is lack of data on entrepreneurial successes in Africa. While there have been numerous research studies on entrepreneurship and family businesses in many regions of the world, there has been relatively little research done in the African context. This lack of research on entrepreneurial success in Africa is due to a variety of reasons such as the fact that most are relatively young and journals are typically housed in universities in developed economies. This chapter describes the success story of a family business in Africa. Specifically, this study sets out to determine the context of starting a family business in Africa: the motivation, type of business, family involvement and the mental attributes, and the challenges in starting and running a family business. Finally, this study recounts some of the lessons from the challenges and successes of the entrepreneur.
