Cachaça production from sugarcane infested by Diatrea saccharalis

Abstract Cachaça is a highly consumed Brazilian spirit, which still needs studies on its agroindustrial processing. We can highlight the effects of infestation of pest insects in the sugarcane, and the chemical-physically characteristics of the drink. So, the aim of the study was to evaluate the consequences of the infestation of the sugarcane borer (Diatrea saccharalis) on the quality of the cachaça. The borer infestation results in less stalks productivity per hectare, and higher rates of acidity and phenol in juice and must. However, the borer did not affect the Brix, Purity, Total Reducing Sugars and pH of raw material. The cellular viability of infested stalks is less than of not infested stalks. The chemical-physical characteristics of the cachaça for both treatments meet the Brazilian legislation. However, the acetic acid is higher for infested stalks.

摘要：卡莎萨（Cachaça）是巴西消费量极高的蒸馏酒，其农产工业加工环节仍有待开展相关研究，其中甘蔗虫害侵扰对其的影响以及该饮品的理化特性均为重要研究方向。本研究旨在探究甘蔗螟虫（Diatrea saccharalis）侵染对卡莎萨品质的影响。结果表明，螟虫侵染会导致单位公顷甘蔗茎秆产量下降，同时蔗汁与醪液中的酸度及酚类物质含量升高；但螟虫侵染并未对原料的白利糖度（Brix）、纯度、总还原糖含量及pH值产生显著影响。此外，受侵染甘蔗茎秆的细胞活力低于未受侵染的茎秆。两种处理方式下产出的卡莎萨的理化特性均符合巴西相关法规要求，但受侵染茎秆所酿卡莎萨的乙酸含量更高。
