摘要
检测了木箱子发酵、竹盘子发酵、堆积发酵和智能培养箱发酵等不同发酵方式下的海南可可豆的单粒重、吸光度、水分、pH、色度,并采用电子鼻测定了未烘烤和烘烤后的可可豆风味,对响应结果进行了主成分分析(PCA)。结果表明:不同发酵方式下的可可豆特性差异明显,采用木箱子和堆积发酵后的可可豆与竹盘子和智能培养箱发酵后的可可豆在电子感官风味分析上差异较大。认为木箱子发酵和堆积发酵为适合海南可可豆的发酵方式,利用该技术可以提高海南可可发酵豆的品质。
Use the different fermentation methods,such as wooden box,plate,heap,intelligence incubator.Test the weight,absorbance at 240 nm,water content,pH and chroma were detected,and electronic nose was applied to detect the difference of dried and roasted fermented beans of Hainan cocoa beans,the principal component analysis（PCA） was used to analyze the data.The results show that different fermentation methods,obviously influence the quality and flavor of Hainan cocoa beans.Hainan cocoa beans fermented in heaps or in wooden box are different of other methods in quality electronic sensory flavor analysis.Fermented in heaps or in wooden box is suitable for Hainan cocoa beans.These two fermentation technology can improve the quality of Hainan cocoa beans.
