Resumo
Analisaram-se várias características morfológicas de amostras de sementes e a qualidade do produto de alguns cultivares de Coffea canephora e de C. congensis, coletadas em quatro localidades do Estado de São Paula Utilizou-se uma escala de cinco pontos, desenvolvida em Angola, para avaliação da qualidade da bebida de C. canephora. Os dados obtidos foram comparados com os dos padrões kouülou de C. canephora do Estado do Espirito Santo e mundo-novo de C. arábica. Verificou-se que 46% das amostras de sementes beneficiadas foram classificadas como pertencentes a C. arábica e, 36%, a C. canephora. As porcentagens de sementes do tipo moca variaram de 10 a 50% para as amostras de C. canephora e de 20 a 40% para C. congensis. Para o mundo-novo essa porcentagem foi de 15%. Os dados referentes à qualidade da bebida indicaram que oito amostras deram bebida significativamente melhor do que a do padrão kouülou e nenhuma se revelou melhor do que a do mundo-novo. Comparações entre as médias de pontos conferidos à bebida de 17 amostras de C. ca- nephora despolpadas com as correspondentes não despolpadas, revelaram diferenças significativas, indicando que a operação do despolpamento contribuiu para a melhoria da qualidade da bebida. As amostras de café despolpadas de C. canephora colhidas em Ribeirão Preto revelaram-se de melhor qualidade de bebida, em relação às das outras três localidades: Tietê, Jaú e Pindorama. Os dados obtidos evidenciaram, ainda, que os cultivares de C. congensis e de C. canephora podem dar bebida de qualidade semelhante.
Coffea canephora and C. congensis cultivars were evaluated for morphological and cup quality characteristics, comparing seed samples from four localities of the State of São Paulo. A five point scale, developed in Angola for testing cup quality of C. canephora, was used. C. canephora cv. Kouillou, from the State of Espirito Santo, and C. arábica cv. Mundo-Novo were used as standards. According t o morphological characteristics 46% of the clean coffee samples were classified as C. arábica a n d 36% as C. canephora. The percentage of peaberries varied from 10 t o 50% for C. canephora and from 20 to 40% for C. congensis, while Mundo-Novo gave 15% of this seed type. Hi relation to the cup quality eight samples proved to be significantly better than Kouillou. However none of the samples showed to be better than Mundo-Novo. A positive and significant effect of pulping on cup quality was observed when comparing 17 pulped coffee samples to the corresponding samples without pulping. Furthermore an effect of locality on cup quality was observed. The best cup quality was obtained from t h e pulped coffee samples of Ribeirão Preto locality. The analysed results pointed also out that C. canephora and C. congensis cultivars can give beverages of similar cup quality.
