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：食品市场对有机农产品的需求日益增长。巴西是全球甘蔗蒸馏酒生产大国，年产量约16亿升。为优化生产流程，全供应链各环节均在积极探索新技术，且有机原料已被应用于饮料生产用甘蔗的种植环节。本研究旨在解析巴西多个州采集的11份有机甘蔗蒸馏酒样本的理化与色谱特征。研究通过理化分析、高效液相色谱（High Performance Liquid Chromatography）与气相色谱（Gas Chromatography，GC）对样本中的次级成分及污染物进行了定性与定量检测。结果显示，有相当比例的有机甘蔗蒸馏酒样本中部分成分浓度超出了巴西农业、畜牧业和供应部（Ministry of Agriculture, Livestock and Provisioning，MAPA）规定的限值，其中酯类（18.20%）、铜及干浸出物（9.10%）的超标情况尤为显著。此类污染物超标问题系生产过程中的操作条件不符合规范所致，未遵循巴西法律所确立的良好生产规范。
