“…The following analyses were carried out in both the original and clarified juices to evaluate the efficiency of the flocculating agent: brix content, total reducing sugars, soluble ash, color (Centro de Tecnologia Canavieira, 2005), total phenolic compounds, (Folin & Ciocalteu, 1927) amino acids (Yemm & Cocking, 1955), proteins (Bailey, 1967). Particle sedimentation rate (settling rate) and sludge volume (Centro de Tecnologia Canavieira, 2005) were also determined during the settling process.…”

“…Amostras de FB, F2 e R foram coletadas e utilizadas para a determinação da atividade da NR (JAWORSKI, 1971) e da GS (FARNDEN e ROBERTSON, 1980) no mesmo dia da coleta. Amostras de um grama de tecido vegetal (FB, F2, C e R) foram homogeneizadas em 20 mL de etanol (80%) e após partição com clorofórmio em igual volume da solução alcoólica (FERNANDES, 1984), a fração solúvel obtida foi armazenada e utilizada posteriormente para determinar os teores de N-amino livre (YEMM e COCKING, 1955), açúcares solúveis (YEMM e WILLIS, 1957), N-NH 4 + (FELKER, 1977) e N-NO 3 - (CATALDO et al, 1975). Também foi avaliado o acúmulo de massa fresca, e no material seco, determinou-se o teor de Ntotal pelo método de Kjeldahl, utilizando-se digestão sulfúrica (TEDESCO, 1983).…”
