“…Para o mineral potássio, foram observadas variações entre 169,18 (Beauregard) e 395,25 (Cuia) mg/100 g de batata-doce, valores superiores aos encontrados anteriormente por outros estudos (LAURIE et al, 2015;SANOUSSI et al, 2016). Nas raízes da batata-doce, o potássio foi o mineral presente em maior quantidade em todos os genótipos avaliados.…”

“…Isso leva a considerar que as batatas-doces analisadas contribuem para a nutrição de gestantes e de crianças, junto a uma alimentação adequada e saudável. Em estudo comparando dados de conteúdo mineral com o consumo de 150 g batata doce biofortificada, demonstrou-se que este forneceria mais de 10% de zinco, ferro e magnésio das necessidades diárias para crianças de 4 a 8 anos de idade (LAURIE et al, 2015).…”

Composição mineral em genótipos de batata-doce de polpas coloridas e adequação de consumo para grupos de risco Mineral composition of sweet potato genotypes with coloured pulps and their consumption adequacy for risk groups ResumoEste estudo objetivou quantificar minerais presentes em genótipos de batata-doce de polpa colorida, selecionados e cultivados pela Embrapa (Empresa Brasileira de Pesquisa Agropecuária), no sul do Rio Grande do Sul, bem como verificar o percentual de adequação de consumo em grupos de risco nutricional. Genótipos de batata-doce cultivados no Banco Ativo de Germoplasma -polpa branca (Rubissol, ILS 12, ILS 10, ILS 24); polpa creme (Cuia, ILS 03, ILS 44); polpa amarela/laranja (Amélia e Beauregard); polpa roxa (ILS 56, ILS 16 e ILS 71) -foram analisados em triplicata. Os minerais foram quantificados por espectrometria de absorção atômica e os resultados foram expressos em miligrama do mineral correspondente a 100 g -1 de amostra úmida. Cálculos dos percentuais de adequação da ingestão diária recomendada de cada genótipo para grupos de risco (crianças entre 4 e 8 anos e gestantes entre 19 e 30 anos), com base no consumo de uma porção média de 200 g diários, foram realizados. As batatas-doces apresentaram grande variação na quantidade de minerais entre os genótipos e o potássio foi o mais abundante em todos estes, com destaque para os genótipos ILS 44, ILS 56 e ILS 71. Os genótipos de coloração roxa se sobressaíram na quantidade de potássio e os de coloração creme, na quantidade de fósforo. O consumo de uma porção média de 200 g de qualquer uma das batatas-doces forneceria 28% da necessidade de magnésio a crianças de 4 a 8 anos, e em torno de 20% das necessidades diárias de magnésio e 10% de potássio para gestantes.

AbstractThe objective of this work was to quantify the minerals present in coloured pulp sweet potato genotypes, selected and cultivated by Embrapa (Empresa Brasileira de Pesquisa Agropecuária), in the southern region of Rio Grande do Sul, Brazil, as well as checking their percentage adequacy for consumption by groups at nutritional risk. The following sweet potato genotypes grown in the Active Germplasm Bank were analysed in triplicate: white pulp (Rubissol, ILS 12, ILS 10 and ILS 24); cream pulp (Cuia, ILS 03 and ILS 44); yellow/orange pulp (Amélia and Beauregard); and purple pulp (ILS 56, ILS 16 and ILS 71). The minerals were quantified by atomic absorption spectrometry and expressed as mg of the corresponding mineral per 100 g -1 of fresh weight. The percentages of adequacy of the recommended daily intake of each genotype for risk groups (children between 4 and 8 years old and pregnant women between 19 and 30 years old) based on the consumption of an average portion of 200 ...

“…Sweet potato (Ipomoea batatas) plays a major role worldwide as a staple crop and is especially important in developing countries (Laurie et al, 2015). Sweet potato is thought to have originated in Latin America (Davidson, *Corresponding author.…”

“…From the Americas, the Spanish brought the sweet potato to Europe, where it spread to Africa, India, China and Japan (Katayama et al, 2017). It is hardy, has low input requirements and is a versatile crop (Laurie et al, 2015). Table 1 describes optimum cultivation parameters for growing IP and OFSP.…”

“…Significantly longer time to harvest and higher fertility requirements are needed for IP production compared to OFSP. The orange flesh sweet potato (OFSP) has significant antioxidant activity, and can potentially improve vitamin A status in children (Laurie et al, 2015;Hotz et al, 2012;Li and Mu, 2012;Burri, 2011). Emerging health benefits of the OFSP are substantial, making it an even more important food -especially for populations in danger of malnutrition (Aywa et al 2013;Kaspar et al, 2013).…”

Orange flesh sweet potato (OFSP) is a globally important staple crop. Health benefits of OFSP are substantial, especially for nutrition-endangered populations. Compared to the Irish potato (IP), OFSP is a richer source of nutrients and fiber. In some parts of the world, OFSP is unfortunately regarded as a poor farmer's crop. This negative reputation has resulted in reduced acceptance of OFSP by populations that could benefit greatly from it. One purpose of this paper is to promote acceptance of OFSP by demonstrating sensory preference of OFSP compared to IP. The second purpose is to recognize a global effort to develop food products using OFSP. Consumer taste tests were conducted to compare OFSP and IP cooked and prepared using common methods of mashing and cubing. Published journal articles that reported development of foods with OFSP as a primary ingredient were identified. Recipe developers must have used a rigorous technique of sensory analysis to test products. Consumers did not show a significant preference for the taste or appearance of mashed or cubed OFSP compared to IP. Researchers from 9 different countries have developed food products that included OFSP in 22 different categories over a 26-year period. OFSP has been successfully utilized in the development of many well-liked food products. Continuous education and exposure of future generations of scientists and consumers to the benefits of OFSP will result in broad-based acceptance.

The 2030 Agenda for Sustainable Development Goals (SDG) of the United Nations puts forward a transformational vision to cope with food security, nutrition and health challenges, in which sweetpotato can play an important role. Globally sweetpotato production is valued at US$53.83 billion. The ARC sweetpotato research and development (R&D) program over the past seven decades delivered 31 genetically improved cultivars via demand‐led breeding, managed the collection and maintenance of 375 accessions, contributed towards the optimization of cultivation practices, developed crop protection and diagnostic services, provided stream‐lined seed systems and technology transfer in processing and enterprise development. The ARC's work is part of a large number of interdependent global programs committed to improving livelihoods and nutrition through sweetpotato. This review shares and analyses major achievements, highlights unique research contributions achieved through partnerships and discusses bottlenecks on funding and up‐take of technologies. New research imperatives will involve root phenotyping, employing marker‐based technologies and genome‐wide association studies through new funding received recently. Exploration of the commercialization potential of processed products made from orange‐fleshed sweetpotato will be a major focus of the R&D program. Expansion of partnerships, marketing and financing will be important for future contribution of sweetpotato to the economy.This article is protected by copyright. All rights reserved
