During the harvesting of its capitula, the leaves, which have long been underutilized by-products, are found be rich in valuable polyphenols with beneficial bioactivities. Motivated by the green economy concept, our team focused on steam explosion (SE) to extract high-value phenolic compounds from Hangbaiju leaves. The research findings indicated that SE pretreatment led to a remarkable increase in the total phenol and flavonoid content in Hangbaiju leaves (26.32 mg CAE/g and 30.72 mg RE/g, respectively), with an increase of more than three-fold. This also enhanced antioxidant capacity and laid a solid foundation for the development of antioxidant products. Notably, 3,4-di-O-caffeoylquinic acid, undetectable in raw leaves, was present in the SE-treated leaves at a concentration of 1.22–4.23 mg/g. Additionally, the yields of 4-O-caffeoylquinic acid, acacetin, and apigenin also increased significantly. Furthermore, the SE-treated Hangbaiju leaves exhibited a high bioaccessible phenolic content after simulated gastric digestion, supporting their use in functional foods and supplements. In conclusion, this research validates the feasibility and effectiveness of SE in the pretreatment of Hangbaiju leaves. It enables the utilization of Hangbaiju leaf residues as resources, alleviates environmental pressure, and clears the path for the development of high-value-added products, thereby making a substantial contribution to the future growth of the green economy.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"231 ","pages":"Article 121221"},"PeriodicalIF":5.6,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we screened the effects of different types of polyamines and their inhibitor D-arginine in longan EC. Exogenous 10 μmol/L spermine demonstrated superior efficacy, enhancing the fresh weight of longan EC by 12.65 % and increasing its flavonoids production rate by 26.11 % versus control. Exogenous spermine also up-regulated the expression of polyamines and flavonoids metabolism genes. Widely targeted metabolomics indicated flavonoids as predominant differential metabolites under spermine treatment, with vitexin-2′-O-glucoside and quercetin-3-O-glucoside-7-O-rhamnoside showing the most pronounced differential accumulation. D-arginine acts mainly as inhibition. Intriguingly, exogenous 10 μmol/L quercetin outperformed Spm and vitexin in promoting both longan EC growth (by 36.58 %) and flavonoids production rate (by 65.08 %), while concomitantly upregulating the expression of polyamines metabolism genes, suggesting a possible synergistic interaction between spermine and quercetin. Furthermore, exogenous quercetin and vitexin facilitated the development of longan EC into globular embryo. Cultivation of longan EC in a stirred bioreactor (5 L working volume) supplemented with 10 μmol/L quercetin achieved 196.15 % higher flavonoid yield than that in solid medium, while reducing the culture duration from 30 to 9 days.

The limiting oxygen index increased to be 52.9 % when 20 % of APP was added. Moreover, the addition of APP also dramatically improved the elongation at break of the film. The elongation at break of films with 20 % of APP was more than three times that of pure gelatin film and GEL/ML film, transforming the film from brittle material to ultra flexible material. Results in this study provided a reference approach for the production of ultra-flexible, UV-shielding and flame-retardant gelatin films.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"231 ","pages":"Article 121214"},"PeriodicalIF":5.6,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143946949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
