    摘要:

    以“朝研219”番茄為試材,，研究了200kV/m,、2h/d的負(fù)高壓間歇靜電場(chǎng)（簡(jiǎn)稱穩(wěn)恒電場(chǎng)）和波動(dòng)場(chǎng)強(qiáng)-200～200kV/m,、頻率40kHz的交變電場(chǎng)預(yù)處理2h（簡(jiǎn)稱交變電場(chǎng)）兩種不同處理對(duì)綠熟番茄果實(shí)適溫（13℃）貯藏品質(zhì)的影響。結(jié)果表明：兩種高壓電場(chǎng)處理均能夠顯著減輕番茄果實(shí)的腐爛指數(shù)（P<0.05）,，電場(chǎng)處理延緩了果實(shí)硬度和可溶性糖,、果皮葉綠素含量的下降，以及可滴定酸,、番茄紅素含量的上升,，從而延緩了果實(shí)的衰老，不同程度提高了果實(shí)的貯藏性,。兩種形式比較,，高壓靜電場(chǎng)處理果實(shí)腐爛指數(shù)顯著好于交變電場(chǎng)處理，其他指標(biāo)則無(wú)顯著差異,。

    Abstract:

    In order to discuss the effect of two types of high voltage electric field treatments on the storage quality of tomato fruit, “Zhaoyan219” tomato was taken as the experimental material, and the two treatments of the negative high voltage intermittent electrostatic field (namely steady electric field) that was 200kV/m and 2h/d and alternative electric field pretreatment (namely alternative electric field) that was -200～200kV/m, 40kHz and 2h on the effect of qualities of mature green tomato fruit during the storage quality(13℃) were studied. The results indicate that the two treatments can lower the decay incidence (P<0.05) remarkably. The decrease of firmness of tomato fruit, the content of soluble sugar and chlorophyll content of tomato peel and the increase of titratable acid and lycopene content are postponed by the effect of high voltage electric field treatments. That is how the infirmness is delayed and the qualities of tomato fruit are improved. 
