Efeito de ondas ultra-sônicas sobre a população de Leuconostoc mesenteroides em caldo de cana-de-açúcar. Pesquisa Agropecuária Tropical, Goiânia, v. 34, n. 3, p. 139-146, set./dez. 2004. Disponível em: <https://www.revistas.ufg.br/pat/article/view/2307>.1517-6398http://repositorio.bc.ufg.br/handle/ri/13127In the present work, first extraction sugarcane juice was irradiated with ultrasound waves to control Leuconostoc mesenteroides. Surface response methodology (central composite model) was used to evaluate the treatment effects. The response variable was the death rate (DR%) of the L. mesenteroides population. The results showed that the highest rate of mortality, 10.55%, was obtained with a power of 50 W for 225 seconds, in sugarcane juice with 18° Brix, pH 4.5 and 45°C.porAcesso AbertoIndústria açucareiraCana-de-açúcarUltra-somSugar industrySugarcaneUltrasoundArtigo
