在國家自然科學(xué)基金、江西省現(xiàn)代農(nóng)業(yè)技術(shù)(柑橘)產(chǎn)業(yè)體系等項(xiàng)目的資助下,江西省果蔬保鮮與無損檢測重點(diǎn)實(shí)驗(yàn)室陳金印教授領(lǐng)銜的果蔬保鮮創(chuàng)新團(tuán)隊(duì)在柚果采后品質(zhì)劣變及調(diào)控技術(shù)等方面研究取得重要進(jìn)展,相關(guān)研究成果分別以《Suppression on postharvest juice sac granulation and cell wall modification by chitosan treatment in harvested pummelo (Citrus grandis L. Osbeck) stored at room temperature》、《Mitigating effects of chitosan coating on postharvest senescence and energy depletion of harvested pummelo fruit response to granulation stress》為題于2021年1月在Food Chemistry在線發(fā)表,以《Chitosan coating alleviates postharvest juice sac granulation by mitigating ROS accumulation in harvested pummelo (Citrus grandis L. Osbeck) during room temperature storage》為題于2020年11月在Postharvest Biologyand Technology在線發(fā)表。
該研究團(tuán)隊(duì)前期研究發(fā)現(xiàn)柚果實(shí)采摘后因其果皮表面粗大的氣孔,相較于其他柑橘品種,更易發(fā)生汁胞?;F(xiàn)象;柚果實(shí)粒化后水分、糖酸等營養(yǎng)物質(zhì)大量流失,囊瓣壁變厚變硬、味同嚼蠟,風(fēng)味及食用品質(zhì)大幅下降,影響其果實(shí)口感、食用價(jià)值及經(jīng)濟(jì)效益。為了進(jìn)一步闡明柚果實(shí)采后品質(zhì)劣變的機(jī)理,研發(fā)延緩其采后粒化的調(diào)控技術(shù),研究團(tuán)隊(duì)從細(xì)胞壁生長、能量虧損、三羧酸循環(huán)和活性氧代謝等多途徑解析了柚果實(shí)采后品質(zhì)劣變的機(jī)制及殼聚糖等綠色保鮮劑對(duì)柚類果實(shí)的保鮮機(jī)理,研究成果對(duì)柚果綠色保鮮劑研制,減少柚果采后損失提供了科學(xué)依據(jù)。
