    摘要:

    利用氣體傳感信息,提出了一種藍(lán)莓貨架期預(yù)測方法,。將藍(lán)莓貯藏在0,、5,、22℃下,,對貯藏微環(huán)境中的3種氣體含量(氧氣、二氧化碳,、乙烯)進(jìn)行了監(jiān)測,,同時將藍(lán)莓5種理化指標(biāo)(腐敗率、硬度,、pH值,、可溶性固形物含量、失重率)作為傳統(tǒng)的品質(zhì)指示指標(biāo)進(jìn)行了獲取,,分析了貯藏微環(huán)境中氣體含量變化和理化指標(biāo)變化的相關(guān)性,,并利用BP神經(jīng)網(wǎng)絡(luò)從氣體角度建立了藍(lán)莓的貨架期預(yù)測模型。結(jié)果表明:藍(lán)莓品質(zhì)的變化受到貯藏溫度的影響,;氣體含量的變化與藍(lán)莓品質(zhì)的變化存在明顯相關(guān)性,;利用BP神經(jīng)網(wǎng)絡(luò)建立的藍(lán)莓貨架期預(yù)測模型具有良好的預(yù)測效果。其中,,0℃的預(yù)測誤差為0.091~0.191d,,5℃的預(yù)測誤差為0.069~0.302d,22℃的預(yù)測誤差為0.094~0.338d,,基本滿足貨架期預(yù)測需要,。

    Abstract:

    Given the importance of blueberry shelf life in ensuring the quality of blueberries during storage, a blueberry shelf life prediction method was proposed from the perspective of gas sensing information. Three kinds of gas content (oxygen, carbon dioxide and ethylene) and five kinds of physical and chemical indexes for blueberry (rate of corruption, hardness, pH value, soluble solids and weight loss rate) in storage environment of 0℃, 5℃ and 22℃ were monitored, the correlation between gas content and physical and chemical indexes were analyzed, and the shelf life prediction model of blueberry was established by using the BP neural network from the perspective of gas. The results showed that the quality of blueberry was affected by the storage temperature, and there was a clear correlation between the change of gas and blueberry quality. Blueberry shelf life prediction model using the BP neural network had good predictive results. Among them, the prediction error was 0.091~0.191d at 0℃, which was 0.069~0.302d at 5℃ and 0.094~0.338d at 22℃. Predicting the shelf life of blueberries by using gas sensing information had the advantages of simple operation and low cost, which was a useful exploration for the shelf life prediction of blueberries.
