Résumé
A industrialização da batata tem sido limitada no Brasil, devido à falta de matéria-prima adequada, sendo a demanda suprida pelas importações de produtos processados. Oito cultivares de batata, adaptadas às condições da região serrana de Minas Gerais, safra 2011, foram avaliadas quanto a sua composição centesimal, cor e conteúdo de amilose. Os resultados obtidos mostraram que as cultivares 'Marcy' e 'Colorado' apresentam características importantes para o cozimento. As cultivares 'Marlen' e 'Pirassu' apresentam atributos requeridos para o processamento na forma de chips e/ou palha e a cultivar 'BRS Ana' para a forma de palitos pré-fritos.
The industrialization of potato in Brazil has been limited because of the low availability of tubers with adequate quality, being supplied by imports of processed products demand. Eight cultivars of potato, adapted to the mountainous conditions of Minas Gerais state, harvest of 2011, were evaluated for their centesimal composition, color and amylose content.The results demonstrated that 'Marcy' and 'Colorado' cultivars showed important characteristic for cooking. The 'Marlen' and 'Pirassu' cultivars showed required attributes for processing in the form of chips or straw and the cultivar 'BRS Ana' for pre-fried sticks.
Résumé
The present work aimed to evaluate opinions and attitudes of consumers during purchase of potatoes, and analyze the availability of French cultivars. By means of focus groups, it was observed that the purchase of potatoes was affected by factors related to the potatoes themselves, such as size and shape, and environmental determinants. Decision making was based on previous experiences and cultural codes already established. Despite the importance of seals of quality, there was no significant indication that potato quality played a more important role than cultural patterns. It was concluded that even when offering specials on high quality cultivars, such as the French cultivar, special offers should be preceded by educational activities to establish cultural codes for purchase of potatoes.
