As olerícolas submetidas ao sistema de cultivo orgânico foram produzidas por agricultores familiares de Seropédica, Rio de Janeiro, Brasil. Foram analisados os teores de umidade, proteínas, lipídeos, cinzas, fibras, de carboidratos totais, além do pH, a acidez total e o teor de sódio das amostras de picles estudadas. Também foi avaliada a qualidade microbiológica de acordo com a Legislação vigente para esta categoria de produto. Os picles estudados não puderam ser denominados “picles orgânicos”, uma vez que a quantidade de vinagre convencional ficou acima do limite máximo estipulado pela Legislação, que permite o uso de matéria-prima de origem não orgânica em quantidade não superior a 5%. De forma geral, os picles estudados apresentaram elevada umidade (acima de 90 %), e pequena quantidade de nutrientes calóricos (carboidratos totais, proteínas e lipídeos), resultando em um produto com baixo teor calórico. Quanto ao teor de sódio, verificou-se que a conserva de pepino e de nabo apresentaram teor de sódio semelhante. O picles de pepino e de nabo estavam dentro dos padrões microbiológicos de qualidade exigidos pela Agência Nacional de Vigilância Sanitária (ANVISA), sugerindo que as normas de Boas Práticas de Fabricação (BPF) foram seguidas pelos agricultores de forma satisfatória. Quanto aos aspectos nutricionais, apesar das amostras de picles terem apresentado baixo valor calórico, o consumo de uma porção diária da conserva de picles de pepino e de nabo foi suficiente para fornecer 30% e 65 % de sódio, respectivamente do valor diário (%VD) recomendado, sugerindo a necessidade de ajuste na formulação dos produtos estudados.</span></p><!--[if gte mso 9]><xml>
