Abstract

Shalgam juice is one of the most popular non-alcoholic beverages in Türkiye and also in many countries. The high amount of production, regarding the high amount of consumption leads to an inevitable amount of solid waste. This amount reaches to almost 12 million kg of fermented black carrot annually. The accumulation of this waste causes fatal environmental pollution. The waste of shalgam juice process, fermented black carrot, retains significant amount of valuable components, such as phenolics, flavonoids, and anthocyanins. In this study new generation green solvents, Natural Deep Eutectic Solvents (NADESs) were screened for the extraction of valuable phenolics from fermented black carrot using ultrasound assisted extraction. The NADESs used were selected from four different groups such as acidic, sugar-based, choline chloride-sugar based and polyol-based. According to the results, the members of polyol and choline chloride sugar NADESs showed up. Choline chloride-glycerol (polyol group), extracted the highest total phenol amount (16.04 mg/g) and also provided the highest antioxidant activity (81.77%). On the other hand, NADESs belonging to choline chloride-sugar group were effective for the extraction of flavonoids and monomeric anthocyanins. Namely, choline chloride-fructose-water extract contained 21.45 mg/g of total flavonoids, while choline chloride-sucrose-water extract contained 1680.51 mg/kg of total monomeric anthocyanins. The performances of NADESs tested were found to be higher than that of water and ethanol showing the high yield recovery of valuable phenolics with NADESs. The results exhibited the significance of the components inside the waste. The remaining valuable content could be easily and efficiently extracted using NADESs and these extracts –as a mixture or after purification- can furtherly be used for different purposes in different fields, such as cosmetics, antioxidant preparations, etc, using a zero-cost waste as the input of the processes.
沙格姆果汁废液中有价酚类天然深共晶溶剂的筛选
沙勒格姆果汁是土耳其和许多国家最受欢迎的非酒精饮料之一。大量的生产,相对于大量的消耗,导致不可避免地产生大量的固体废物。每年发酵黑胡萝卜的产量达到近1200万公斤。这种废物的积累造成了致命的环境污染。黑胡萝卜发酵过程中产生的废液保留了大量的酚类物质、类黄酮和花青素等有价值的成分。本研究筛选了新一代绿色溶剂天然深共晶溶剂(Natural Deep Eutectic solvent, NADESs),用于超声辅助提取发酵黑胡萝卜中有价酚类物质。所使用的nades从酸性、糖基、氯化胆碱糖基和多元醇基四种不同的组中选择。根据结果,多元醇和氯化胆碱糖的成员NADESs出现。氯胆碱-甘油(多元醇组)总酚含量最高(16.04 mg/g),抗氧化活性最高(81.77%)。另一方面,氯胆碱糖基NADESs对黄酮类和单体花青素的提取效果较好。氯胆碱-果糖-水提取物的总黄酮含量为21.45 mg/g,氯胆碱-蔗糖-水提取物的总单体花青素含量为1680.51 mg/kg。实验结果表明,NADESs的性能高于水和乙醇,表明NADESs对有价酚类物质的收率较高。结果表明了废弃物中各组分的重要意义。剩余的有价值的成分可以使用NADESs轻松有效地提取,这些提取物-作为混合物或纯化后-可以进一步用于不同领域的不同目的,例如化妆品,抗氧化剂制剂等,使用零成本废物作为该过程的输入。
