摘要: 为进一步明确地理标志产品“宜宾酒”原酒的主要品质指标,为相关标准的修订提供依据。按照GB/T 10345—2007《白酒分析方法》,对524份原酒样品的乙醇体积分数、总酸和总酯含量,以及其中267份样品的单体物质(乙醛、乙缩醛、正丙醇、仲丁醇、异丁醇、正丁醇、异戊醇、乙酸乙酯、丁酸乙酯、乳酸乙酯和己酸乙酯)含量进行测定,采用SPSS17.0进行统计分析。结果发现,乙醇体积分数越高,总酸、总酯、乙酸乙酯和己酸乙酯含量差异越大。总体上,“宜宾酒”原酒具有适宜含量的总酸、高含量的总酯和己酸乙酯。样品中达到DB511500/T10—2014《地理标志产品多粮浓香型白酒(宜宾酒)传统固态法酿造工艺要求》标准特级酒要求的比例很高,可依据本研究对相关内容进行修订。该研究为“宜宾酒”相关标准的修订提供了科学依据。

Abstract: This study aimed to clarify the main physicochemical quality indicators of base spirit of the geographical indication product Yibin spirit for the purpose of providing a basis for the amendment of relevant standards. This investigation determined the alcohol (%, V/V), total acid and total ester contents of 524 samples and the contents of individual compounds including acetaldehyde, acetal, n-propyl alcohol, sec-butyl alcohol, isobutanol, n-butyl alcohol, isoamyl alcohol, ethyl acetate, ethyl butyrate, ethyl caproate and ethyl lactate in 267 of these samples according to the national standard (GB/T 10345-2007). Statistical analysis of data was performed with the SPSS software package, version 17.0. The results showed that the higher the alcohol content was, the greater the differences in total acids, total esters, ethyl acetate and ethyl caproate contents were. Overall, Yibin base spirit had appropriate content of total acids and high levels of total esters and ethyl caproate. A high proportion of these 524 samples were recognized as premium products according to the Technological Requirement for Solid-State Fermentation of Traditional Multi-Grain Luzhou-Flavor Liquor (Yibin liquor) (DB511500/T10-2014).
