摘要

臭氧微納米氣泡水（O3-MNBW） 是一種創(chuàng)新技術(shù)，通過去除殺蟲劑、霉菌毒素和其他污染物來(lái)延長(zhǎng)水相臭氧的反應(yīng)性并保持水果和蔬菜的新鮮度和質(zhì)量。不同濃度 O 處理的歐芹品質(zhì)3-在 20 °C 下儲(chǔ)存 5 d 期間對(duì) MNBW 進(jìn)行調(diào)查，發(fā)現(xiàn)歐芹暴露于 2.5 mg·L?1O3-MNBW 有效地保留了歐芹的感官品質(zhì)，與未經(jīng)處理的歐芹相比，體重減輕、呼吸速率、乙烯產(chǎn)生、MDA 水平較低，硬度、維生素 C 和葉綠素含量較高。The O3-MNBW 處理還提高了總酚和類黃酮的水平，增強(qiáng)了過氧化物酶和抗壞血酸過氧化物酶活性，并抑制了儲(chǔ)存歐芹中的多酚氧化酶活性。使用電子鼻鑒定的五個(gè)揮發(fā)性特征（W1W，硫化合物;W2S，乙醇;W2W，芳香族和有機(jī)硫化合物;W5S，氮氧化物;W1S，甲烷）對(duì) O 的響應(yīng)顯著降低3-MNBW 治療。共鑒定出 24 種主要揮發(fā)物。代謝組學(xué)分析確定了 365 種差異豐度代謝物 （DM）。其中，30 和 19 個(gè) DMs 與 O 中特征性揮發(fā)性風(fēng)味物質(zhì)代謝相關(guān)3-MNBW 和對(duì)照組。The O3-MNBW 處理增加了大多數(shù)與風(fēng)味代謝相關(guān)的 DMs 的豐度，并降低了柚皮苷和芹菜素的水平。我們的結(jié)果提供了對(duì)響應(yīng)歐芹暴露于 O 的調(diào)節(jié)機(jī)制的見解3-MNBW，并確認(rèn)了 O 的潛在用途3-MNBW 作為一種保存技術(shù)。

The production and use of ozone micro-nano bubble water (O3-MNBW) is an innovative technology that prolongs the reactivity of aqueous-phase ozone and maintains the freshness and quality of fruits and vegetables by removing pesticides, mycotoxins, and other contaminants. The quality of parsley treated with different concentrations of O3-MNBW was investigated during storage at 20 ℃ for 5 d, and found that a ten-minute exposure of parsley to 2.5 mg·L?1 O3-MNBW effectively preserved the sensory quality of parsley, and resulted in lower weight loss, respiration rate, ethylene production, MDA levels, and a higher level of firmness, vitamin C, and chlorophyll content, relative to untreated parsley. The O3-MNBW treatment also increased the level of total phenolics and flavonoids, enhanced peroxidase and ascorbate peroxidase activity, and inhibited polyphenol oxidase activity in stored parsley. Five volatile signatures identified using an electronic nose (W1W, sulfur-compounds; W2S, ethanol; W2W, aromatic- and organic- sulfur compounds; W5S, oxynitride; W1S, methane) exhibited a significant decrease in response to the O3-MNBW treatment. A total of 24 major volatiles were identified. A metabolomic analysis identified 365 differentially abundant metabolites (DMs). Among them, 30 and 19 DMs were associated with characteristic volatile flavor substance metabolism in O3-MNBW and control groups, respectively. The O3-MNBW treatment increased the abundance of most DMs related to flavor metabolism and reduced the level of naringin and apigenin. Our results provide insight into the mechanisms that are regulated in response to the exposure of parsley to O3-MNBW, and confirmed the potential use of O3-MNBW as a preservation technology.
