However, their application is limited because of their inherent instability and susceptibility to rapid color changes. Copigmentation and encapsulation present promising strategies to increase both the stability and color intensity of anthocyanins. This study aimed to improve the stability and color intensity of anthocyanins extracted from rambutan peels through copigmentation and encapsulation. Rambutan peels were blanched, dried, and ground into powder before being subjected to ultrasound-assisted extraction via 0.2% citric acid in 96% ethanol. Copigmentation was conducted by adding Tannic acid at molar ratios of 1:0, 1:100, 1:150, and 1:200, followed by encapsulation with 10% maltodextrin. This study evaluated the color stability and anthocyanins degradation of copigmented rambutan peel anthocyanins extract, along with its characteristics and stability in powder form during storage at low temperatures. The results showed that increasing Tannic acid from a molar ratio of 1:100 to 1:200 caused a 10 nm wavelength shift, and the absorbance increased from 3 to 15%. The 1:150 molar ratio resulted in the most significant improvement, effectively preserving red color stability and reducing anthocyanins degradation in copigmented anthocyanins. FT-IR analysis confirmed that the improved stability of the anthocyanins following tannic acid addition resulted from intermolecular interactions. Moreover, the incorporation of tannic acid produced anthocyanins powder with smoother surfaces and greater uniformity. The highest half-life values and the lowest ΔE values were observed for the anthocyanins powder stored at -16 ± 5 °C.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":564,"journal":{"name":"Food Biophysics","volume":"20 4","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145078863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evaluations included Fourier transform infrared (FTIR) spectroscopy, sulfhydryl content, particle size, gel electrophoresis, surface hydrophobicity, solubility, water holding capacity, contact angle, and emulsifying activity and stability. Key findings revealed that PAW treatment induced partial unfolding of SPI, enhanced α-helix structure while reducing β-sheet content, particularly in the PAW20 group. Sulfhydryl group oxidation led to disulfide bond formation, transiently exposing buried groups and decreasing total sulfhydryl content. Surface hydrophobicity and solubility peaked at PAW15 treatment, significantly enhancing SPI’s emulsifying properties. Prolonged treatment (> 15 min) caused protein aggregation, diminishing functionality. Optimal PAW15 treatment improves SPI’s structural flexibility and interfacial properties, offering a sustainable strategy for developing high-performance plant protein ingredients in food systems.

Of particular interest is the role of the aqueous solvent in controlling small molecule diffusivity. At a low level of solids, the presence of solvent alters the physical landscape of the protein and defines critical parameters such as crosslink density, mesh size and intermolecular coupling constant as tuneable properties to control release. As the level of solids increases, the landscape again shifts. Here, protein molecules can be treated using the free volume theory to ascribe a link between the mechanical glass transition temperature and bioactive compound release.
