为了对玉米黄浆进行长时间检测估测出玉米黄浆保质期,采用电子鼻PEN3对玉米黄浆挥发性物质进行检测,运用主成分分析(PCA)、线性鉴别分析(LDA)研究室温和冷藏保存的玉米黄浆变质程度,结果表明:室温保存的样品,每日测量第4天发生略微变质,7天发生严重变质;冷藏样品,每周检测,在轻微变质后每天进行检测,在第28天发生轻微变质,第39天发生严重变质。
為瞭對玉米黃漿進行長時間檢測估測齣玉米黃漿保質期,採用電子鼻PEN3對玉米黃漿揮髮性物質進行檢測,運用主成分分析(PCA)、線性鑒彆分析(LDA)研究室溫和冷藏保存的玉米黃漿變質程度,結果錶明:室溫保存的樣品,每日測量第4天髮生略微變質,7天髮生嚴重變質;冷藏樣品,每週檢測,在輕微變質後每天進行檢測,在第28天髮生輕微變質,第39天髮生嚴重變質。

In order to assess corn gluten shelf life for a long time. The determination of corn gluten volatile matter to carry on the analysis by the electronic nose PEN3, using principal component analysis (PCA), linear discrimination analysis (LDA) detection estimate corn gluten shelf life for long time which divided into room temperature and refrigerated storage. The results showed that:room temperature samples sampling every day. occurring slightly metamorphic at the 4th day, occurring heavily metamorphic at the 7th day. Room temperature samples sampling every day, take sample 5 mL every week which stored refrigerated occurring slightly metamorphic at the 28th day, occurring heavily metamorphic at the 39th day.
