The present study employed ultrasound-assisted glycosylation of ovalbumin (OVA) and dextran (Dex) generate conjugate carrier for AC improve its stability. results showed that sonication significantly improved the progression Maillard reaction OVA. Compared traditional glycosylation, ultrasound treatment a higher degree grafting, lower number free-SH, smaller particle size uniform distribution. SDS-PAGE indicated covalent interaction. Intrinsic fluorescence (INF), Fourier transform infrared spectroscopy (FTIR), Circular dichroism (CD) analysis suggested altered OVA structure. scanning electron microscope (SEM) X-ray diffractometer (XRD) observed complex had more compact smoother structure protein unfolding were better. solubility increased after glycosylation. Thermal gravimetric (TGA) Differential calorimetry (DSC) glycosylated conjugates can thermal stability In addition, an processing storage conjugated with carrier. protein-anthocyanins may help provide new ideas scientific basis development naturally sourced anthocyanins-relevant products in pharmaceutical food industry applications.

Extraction of anthocyanins from Lycium ruthenicum Murr. (L. ruthenicum) is a notable challenge in food production, requiring methods that balance efficiency and safety. In this study, we conducted comparative analysis the extraction by natural air drying (NAD), vacuum freeze (VFD), hot (HAD), microwave (MVD) combined with ultrasonic-assisted enzymolysis (UAEE). The results demonstrated yield antioxidant activity were significantly higher VFD. This phenomenon can be attributed to modification raw material's microstructure, leading an increased specific such as Cyanidin-3-galactoside, Delphinidin chloride, Cyanidin, Petunidin. According pretreatment results, process was further optimized. highest (3.16 g/100 g) obtained following conditions: 0.24 % pectinase, 48 °C, solid:liquid = 1:21, 21 min ultrasonic time. study improves commercial value potential application L. industry.

Sustainable Extraction of Fresh Banana Inflorescence by ASE: Optimization and Characterization of Anthocyanin Rich Extracts by LC-UV-MS/MS

Foods, Journal Year: 2025, Volume and Issue: 14(8), P. 1299 - 1299

Published: April 8, 2025

Sustainable and environmentally friendly extraction methods for natural bioactive compounds are gaining significant attention in the food, beverage, nutraceutical industries. Among these compounds, anthocyanins, which potent antioxidants, have garnered particular interest due to their health-promoting properties. Banana inflorescence, an underutilized agricultural by-product, is a rich source of compounds. However, often energy-intensive, raises concerns about environmental sustainability. Accelerated solvent (ASE) has emerged as efficient less energy-consuming method isolating This study investigates optimization ASE phenolic including from fresh banana inflorescence. The effect parameters, temperature (60, 80, 100 °C), type (water, ethanol, methanol), composition (50% ethanol + 50% water, 75% 25% 100% methanol methanol, water), on efficiency was evaluated. results showed that most effective conditions were water at °C, yielding highest concentrations total phenolics (1239.58 ± 20.83 mg/100 g), antioxidant activity (2.21 0.03 mg/mL), anthocyanins (22.82 mg 1.91/100 g). LC-UV-MS analysis revealed three primary anthocyanidins: cyanidin-3-rutinoside, delphinidin-3-rutinoside, petunidin-3-rutinoside. These findings suggest waste product, can be efficiently utilized using ASE, contributing sustainable practices food optimized process provides promising approach valorization enhancing its potential functional ingredient products.

The recent increase in sustainability awareness has triggered the industry to establish novel, eco-friendly sources of plant-based ingredients. In present study, hibiscus flowers (Hibiscus sabdariffa L.) were investigated as a sustainable source anthocyanins for use spray-dried ingredients with antioxidant capacity. To this end, extraction and spray-drying microencapsulation flower optimized final products evaluated their oxidative stability index. Initially, preliminary experiments carried out evaluate effects selected processing parameters on anthocyanin extraction. Next, was through 22 central composite design, considering ethanol concentration (44–56% v/v) time (1.6–6.4 h) independent factors. optimum conditions (8 h, 41.6% v/v concentration) used produce anthocyanin-rich extracts, which microencapsulated by spray drying using design carrier addition rate (1–3% w/v) inlet temperature (160–192 °C) Maximum values solids recovery (60.8%) retention (96.0%) reached when 3.2% w/v starch–alginate blend 170.7 °C used.

Evidence suggests that polyphenol-rich foods like berries may help counteract aging-related disorders such as vascular dysfunction and arterial stiffness. However, few intervention studies have been conducted in older adults. This study aimed to assess whether the consumption of blueberries improve function subjects. A randomized, controlled, crossover trial was a group 20 volunteers over 60 years old. Participants consumed either blueberry mousse (250 g, providing 480 mg anthocyanins - ACNs) or control product mL sugared water), with treatments separated by at least 1-week. Reactive hyperemia index (RHI), augmentation (AIx), blood pressure, heart rate were measured baseline 2 h post-consumption. Blood samples collected after 1, 1.5, 4 from intake evaluate ACN bioavailability, metabolic, markers. Sixteen subjects completed (9 males, 7 females; mean age 69 ± 5 years). Blueberry significantly increased RHI compared (mean difference + 0.42, 95 % CI: 0.01-0.082, p < 0.05). Maximum serum concentration observed (20.3 7.4 ng/mL). No association found between improvement total ACNs, but significant positive correlation detected delphinidin cyanidin-3-glucoside (p 0.01). effects on AIx, other markers found. In conclusion, peripheral adults, potentially due levels. Further are needed corroborate these findings elucidate mechanisms involved.
