摘要:近红外光谱分析技术作为近几年一种新兴的检测技术,具有无需预处理、速度快、成本低、无污染、
不破坏样品化学性质、结果重演性高、绿色环保、多成分可同时分析等优点。目前,我国的酿酒企业多以品评
作为酒体质量检测与等级划分的标准,随着近红外光谱分析技术的引入,这为酒体的品评及成分分析提供了
一种快速准确科学的分析方法。本文综述了近红外光谱分析技术在目前中国酿酒行业中的应用进展研究,涵盖
了白酒、葡萄酒、啤酒、黄酒,并对红外光谱分析技术的进一步发展做了展望。

ABSTRACT: In Tecent years, ncar infrared spectroscopy as an merging detection tcchnology has many ad-
vantages, which include no need to pre-treatment, last, low-cost, no pollution, and no damage to the chemical
nature of the sample, the results of a repeat of the high, green, multi-component analysis, etc. At present, qual
Ity testing was takcn as a kind of standard for liquor quality detection and hierarchies in our country. With the
introduction of ncar-infrared spectroscopy, there is a last, accuratc and scicnlilic method and composition Ior
lasting wine analysis. In this paper, the progress o[ the application of near infrared spectroscopy in Chinas wine
industry was summarized, which has covered liquor, wine, and beer and the further development of infrared
spcctroscopy tcchniquc direction was also put forward
