Desenvolvimento de amidos fosfatados de batata-doce e mandioca e aplicação como substitutos de gordura em sorvetes

Abstract

O mercado de amidos vem crescendo e se aperfeiçoando, levando à busca de produtos com características específicas que atendam às exigências da indústria. Neste contexto a produção de amidos modificados é uma alternativa. Atualmente se observa uma intensa competição entre os setores de desenvolvimento de produtos nas indústrias, para oferecer aos consumidores alimentos com baixos teores de gordura. Os amidos podem sofrer várias modificações com a finalidade de serem usados como substitutos de gordura, e os amidos modificados têm-se mostrado os mais promissores substitutos de gordura. Levando em conta a importância dos amidos para o mercado de alimentos e o interesse em produtos alimentícios com menor teor de gordura, o presente trabalho teve como objetivo desenvolver substituintes de gorduras a partir de amidos de batata-doce e mandioca e avaliar o comportamento dos amidos modificados na formulação de sorvetes de massa com teores de gordura reduzidos. Para a modificação dos amidos de mandioca e batata-doce os reagentes utilizados foram tripolifosfato de sódio (STPP) e trimetafosfato de sódio (STMP) cedidos pela Astaris do Brasil S.A. Após ensaios prospectivos, definiram-se as melhores condições para a modificação dos amidos de mandioca e batata-doce. Os amidos foram fosfatados por via úmida e por via seca,em pH 9,5 com porcentagem de 5% de tripolifosfato de sódio (STPP) e 1% de trimetafosfato de sódio (STMP). A fosfatação teve início à temperatura ambiente sob agitação constante e depois de 1 hora o amido foi transferido para bandejas de alumínio forradas com plástico poliéster e levados a estufa a 130ºC por 6 horas. Os amidos modificados foram analisados quanto as suas propriedades físicas e químicas, funcionais, reológicas e por difração...

The starch market comes growing and if perfecting, leading to the search of products with specific characteristics that take care of to the requirements of the industry. In this context the modified starch production is an alternative. Currently if it observes an intense competition enters the sectors of development of products in the industries, to offer to consuming foods with low texts of fat. The starches can suffer some modifications with the purpose to be used as substitute of fat, and the modified starches have revealed the most promising substitutes of fat. Taking in account the importance of starches for the food market and the interest in nourishing products with lesser text of fat, the present work had as objective to develop fat substitutes from cassava and sweet potato starches and evaluate the behavior of starches The starch market comes growing and if perfecting, leading to the search of products with specific characteristics that take care of to the requirements of the industry.
