Inaugural address delivered on 2 November 2011 / Marietjie Herselman was born in the Langkloof, where she matriculated at the McLachlan High School. She obtained a BSc (Physiology and Dietetics) degree at Stellenbosch University and for the next 18 years worked as a dietitian at Tygerberg Hospital, where she specialised in renal nutrition. She obtained a master’s degree in nutrition in 1985 and in 1991 was appointed as a lecturer in the Department of Human Nutrition, Faculty of Health Sciences, at Stellenbosch University. In the same year she obtained her PhD in nutritional sciences at this university, where she was later promoted to senior lecturer (1995), associate professor (2001) and full professor (2010). From 2008 to 2010 she was appointed first as acting head and later as head of the Division of Human Nutrition. She served on the Professional Board of Dietetics from 1998 to 2003 and also on various sub-committees of the Board. She regularly reviews papers and research applications for scientific councils/associations as well as five national and four international scientific journals. Currently, she serves on the editorial boards of four international scientific journals and in 2008 she was elected as the co-editor (Africa region) of the international journal Nutrition. She successfully delivered 17 master’s students and published 29 scientific papers in national and international journals and three chapters in textbooks. Marietjie also presented papers at 19 international and 37 national conferences. Three international and four national awards were bestowed on her for her research in renal nutrition. She played a leading role in the initiation of the Community Nutrition Security Project (CNSP) in the Breede Valley, as part of Stellenbosch University’s HOPE Project, as well as the NOMA master’s programme in Nutrition, Human Rights and Governance in collaboration with the universities of Oslo and Akershus (Norway) as well as Makerere and Kyambogo (Uganda).

Introdução A hipovitaminose A é reconhecida mundialmente como um dos problemas nutricionais mais importantes, causando impacto negativo na saúde pública por afetar alguns setores da população e pelas sérias conseqüências à saúde. Seus efeitos deletérios justificam o compromisso do governo brasileiro no controle e erradicação da deficiência desta vitamina. Objetivo Comparar o teor de vitamina A de alimentos comuns para a população brasileira com aqueles desenvolvidos com a substituição parcial do óleo/gordura utilizados na sua preparação por azeite de dendê, e avaliar suas características sensoriais e sua aceitação. Metodologia Foram desenvolvidas as seguintes preparações: sequilho salgado, sequilho doce e biscoito de polvilho. Para a caracterização das amostras dos produtos desenvolvidos, com e sem dendê, foram realizadas análises de umidade, atividade de água, composição centesimal, estabilidade oxidativa, cor, textura e perfil de ácidos graxos. A vitamina A foi determinada pela quantificação de -caroteno presente nas amostras. Todas as análises foram realizadas quando o alimento foi elaborado (T0) e após 30 dias (T30). As preparações desenvolvidas foram submetidas à análise sensorial. Resultados Os resultados das análises de umidade, atividade de água, composição centesimal e estabilidade oxidativa dos biscoitos sem dendê não diferiram significativamente das amostras com dendê, excetuando-se o biscoito de polvilho, onde possivelmente uma vedação deficitária da embalagem alterou algumas destas variáveis no T30. Quanto à cor, à textura e ao perfil de ácidos graxos, observou-se que as alterações ocorridas nos biscoitos com dendê foram em função da composição do próprio azeite. Com relação ao teor de vitamina A, todos os produtos com dendê apresentaram concentrações significativas deste nutriente quando comparados aos biscoitos sem dendê. No T30, o biscoito de polvilho não apresentou boa retenção da vitamina A, provavelmente em função da tecnologia adotada, que promoveu a aeração do produto, e pela vedação deficitária. Mesmo assim o produto pode, de acordo com a ANVISA, ser considerado fonte de vitamina A e, portanto, capaz de atender parcela importante das necessidades nutricionais. Todos os produtos tiveram boa aceitação no T0, porém foram rejeitados no T30. Conclusão- o azeite de dendê é uma potencial fonte de vitamina A e pode ser utilizado no enriquecimento de alimentos visando o controle da hipovitaminose A. / Introduction Vitamin A deficiency is recognized as one of the most important nutritional problems, and its causing negative effects in public health because it affects some population sections as well as the serious consequences to health. Its deleterious effects justify the Brazilian government commitment to control and vitamin deficiency eradication. Objective Compare the vitamin A content from the brazilian population ordinary foods with those developed with partial substitution of the oil/fat normally used for palm oil, and assess its sensorial characteristics and acceptance. Methodology The follow prepares were developed: salt starchy biscuit, sweet starchy biscuit and cookies made from cassava flour. To describe the samples of the developed products with and without palm oil, moisture, water activity, centesimal composition, oxidative stability, color, texture and fatty acids profile were performed. The vitamin A was determined by -carotene quantification in samples. All analysis were done when the food was made (T0) and after 30 days (T30). All the developed prepares were submitted to a sensorial analysis. Results The biscuits with no palm oil, contents of moisture, water activity, centesimal composition, oxidative stability, results were not significantly different from biscuits with palm oil. It has excepted the cookies made from cassava flour, a possible pack defective seal changed some of these variables during T30. The color, texture and fatty acids profile changes on biscuits with palm oil happened because of the own oil composition. All products with palm oil have shown significantly vitamin A content concentrations compared with biscuits with no palm oil. The cookies made from cassava flour didnt show a good vitamin A retaining during T30. It happened probably because of the technology used that organized the product aeration and by the defective seal. According to ANVISA the product could be considerate vitamin A source anyway, and, therefore it is able to reach important part of nutritional necessities. All products had good acceptation during T0, however they were rejected during T30. Conclusion- The palm oil is a vitamin A powerful source and can be used to foods fortification aimed at vitamin A deficiency control.
