Um grupo de cientistas japoneses criou dispositivo que pode ser colocado em película aderente, capaz de detectar o estado de conservação da carne ou do peixe, reported today (5) o jornal Nikkei.

Trata-se dematerial inteligente”, with 1 centímetro de comprimento, que reage ao ser colocado sobre os alimentos e cuja utilização poderá evitar casos de intoxicação alimentar, de acordo com o grupo de pesquisadores da Universidade de Yamagata, no Norte do Japão.

O sensor é capaz de detectar a histamina, uma substância gerada quando as bactérias começam a decompor os aminoácidos dos alimentos e que é responsável por sintomas de intoxicação alimentar, mesmo em pequenas quantidades.

O aparelho integra um microcircuito impresso em material semicondutor, em película aderente e, no future, poderá ser instalado em embalagens de modo a fornecer informação automática sobre o estado de conservação dos alimentos.

currently, outros sensores com a mesma finalidade estão sendo desenvolvidos, mas maiores, disseram os cientistas japoneses.

A partir dessa experiência, os pesquisadores esperam desenvolver um dispositivo para comercialização no prazo de três anos, acrescentou o diário.

A equipe da Universidade de Yamagata, dirigida pelo cientista Shizuo Tokito, desenvolve ainda um sistema para ligar essa tecnologia a celulares, de modo que os consumidores possam receber informação a distância sobre o estado dos alimentos.
