O consumo por alimentos beneficos a saude vem conquistando cada dia mais adeptos a procura por melhor qualidade de vida, principalmente quando se trata de individuos com restricoes como o consumo de acucar (Diabetes mellitus). Pensando nessas restricoes, pesquisou-se sobre as propriedades do Matcha (cha soluvel) produzido a partir da moagem das folhas da Camellia sinensis, sua composicao quimica constituida por polifenois especialmente as catequinas como substâncias bioativas, para posterior confeccao de um doce adicionado de Matcha. Nas analises fisico-quimicas, foram determinados o teor de umidade, cinzas, proteinas, lipidios e carboidratos. Os resultados da espectroscopia na regiao do infravermelho demonstraram maior quantidade de epigalocatequina galato no Matcha importado em comparacao ao nacional. Utilizando o Matcha importado elaborou-se o doce, a espectroscopia na regiao do infravermelho do doce, demonstrou que mesmo apos a coccao, a intensa banda em 1030 cm-1 manteve-se sem alteracao no teor de epigalocatequina galato, mostrando que o composto esta presente no doce praticamente sem alteracao na sua quantidade.
