Brazilian organic sugarcane spirits: Physicochemical and chromatographic profile

ABSTRACT There has been a growing demand for products from organic agriculture for the food market. Brazil leads the production of sugarcane spirits and produces about 1.6 billion liters/year. New technologies have been sought throughout the supply chain to improve production, and organic raw material has been used in the production of sugar cane for the production of beverages. This study aimed to define the physicochemical and chromatographic profiles of eleven organic sugarcane spirits samples from various Brazilian states. The secondary components and contaminants were identified and quantified through physicochemical analyses, HPLC and gas chromatography (GC). A significant percentage of the organic sugarcane spirits samples contained concentrations of components that were above the limits required by the Ministry of Agriculture, Livestock and Provisioning (MAPA), specifically the esters (18.20%), copper and dry extract (9.10%). This contamination is caused by bad conditions employed during the production process, which are not in compliance with the good manufacturing practices determined and legislated by Brazilian law.

摘要
食品市场对有机农业产品的需求日益增长。巴西为全球甘蔗蒸馏酒生产大国，年产量约16亿升。当前全供应链均在探索新技术以优化生产流程，且饮料生产所用甘蔗已采用有机原料。本研究旨在对采自巴西多个州的11份有机甘蔗蒸馏酒样品的理化与色谱特征进行表征。研究通过理化分析、高效液相色谱（High Performance Liquid Chromatography, HPLC）及气相色谱（Gas Chromatography, GC）对样品中的次生成分与污染物进行定性与定量分析。结果显示，有相当比例的有机甘蔗蒸馏酒样品中部分成分浓度超出巴西农业、畜牧业与供应部（Ministry of Agriculture, Livestock and Provisioning, MAPA）规定的限值，具体涉及酯类（超标样品占比18.20%）、铜及干浸出物（超标样品占比9.10%）。此类污染系生产过程中未遵循巴西法律确立与立法规范的良好生产规范的不良操作所导致。
