Red date fermented wine, as a nutritious traditional fruit wine, is deeply influenced by the volatile organic compounds during the fermentation process in terms of its quality（VOCs）The impact of dynamic changes. These compounds include esters, aldehydes, and alcohols, which directly determine the fruity aroma, richness, and potential odor risk of the wine. Traditional detection methods such as gas chromatography-Mass spectrometry combined（GC-MS）Although precise, it requires complex sample preprocessing, making it difficult to meet real-time monitoring requirements. prosunCnoseThe electronic nose, with biomimetic olfactory technology as its core, provides an efficient and non-destructive solution through capture and analysisVOCsAssist in optimizing the fermentation process of jujube wine to ensure a smooth transition from astringency and bitterness to mellow aroma.

prosunCnoseElectronic nose simulates the human olfactory system and is equipped with metal oxide semiconductors（MOS）Multi sensor array generates selective response to different volatile compounds, forming a unique "electronic fingerprint" of the sample. Principal Component Analysis of Equipment Application（PCA）Linear Discriminant Analysis（LDA）Wait for algorithms to process signals, achieve sample classification and trend prediction. The detection process is simple, requiring only a few seconds to a few minutes of response time. It supports online sampling and wireless data transmission, with high sensitivity, making it particularly suitable for complex substrates such as red date wine with drastic changes in volatile concentration.

In practical applications, this electronic nose can be used for flavor monitoring of jujube fermented wine. Taking red dates as raw materials and fermentation with brewing yeast as an example, the electronic nose tracks key points in real-timeVOCsEvolution: In the early stages of fermentation, ester compounds such as ethyl acetate dominate and contribute distinct fruity characteristics; In the middle stage, there is a significant increase in higher alcohols and acids, with higher levels of aromatic compounds and a tendency towards richer flavors, but caution should be taken against the accumulation of astringency and bitterness; In the later stage, if there is an increase in odor compounds such as sulfides, timely intervention can be carried out through data feedback. passPCAAnalysis: The electronic nose clearly clusters and distinguishes samples from different stages. In addition, in the quantitative study of jujube wine fermentation, the combination of electronic nose and multiple linear regression model successfully predicted the dynamic changes in alcohol content, verifying its reliability in rapidly evaluating the fermentation process.

In short, BaoshengCnoseElectronic nose driven by objective dataVOCsAnalysis has injected intelligent elements into the quality determination of jujube fermented wine, improving process consistency and product market value.
