Enhancing the Stability of Strawberry Anthocyanins Complexed to β-Cyclodextrin and Starch toward Heat, Oxidation, and Irradiation.

ABSTRACT: The instability of anthocyanins limits their application in food supplementation and in the food industry. Stabilities of strawberry anthocyanins (AN) were improved by complexation with both β-CD and starch against heat, H₂O₂, light, and UV irradiation. The stability of AN against H₂O₂ (2.21 mM) dropped (<20%) in 6 h but was enhanced in β-CD (49.32%) and starch (96.84%) complexes. Under light conditions, AN in the solid and solution (3.88 g/100 mL) forms degraded to 36.49 and 11.11%, while β-CD and starch complexes displayed stabilities of 98.20 and 91.76%, respectively, after 60 days. Under UV irradiation, AN showed similar instability where both AN forms expressed stabilities of 36.75 and 66.18%, respectively, after 168 h, while β-CD and starch complexes exhibited 51.13 and 40.10%, respectively. LC-MS-ESI showed that photoirradiation of both destroyed the full conjugation of the flavylium ring of the major components, pelargonidin and cyanidin hexoses; the mechanism was proposed. Docking binding models of major AN components in β-CD were obtained.

Project description:Recent improvements in colorectal cancer (CRC) incidence, mortality, stage at diagnosis, and survival in the general U.S. population have been attributed to routine screening with prompt removal of polyps, early detection, and timely and appropriate treatment. American Indians/Alaska Natives (AI/ANs) have not experienced improvements in CRC related outcomes and are significantly less likely than non-Hispanic Whites to receive recommended CRC screening. The purpose of this three-arm randomized controlled trial is to determine the efficacy of interventions designed to enhance CRC screening. The study also uses mixed methods to finalize the intervention and to determine promoters and barriers of screening. The study also conducts process evaluation to determine cost-effectiveness of the interventions, fidelity of study implementation, and to develop plans to sustain and scale-up the intervention model. The study will determine the efficacy of serially implemented interventions of graded intensity for increasing CRC screening using the fecal immunochemical test (FIT) in accordance to recommended guidelines among average risk American Indians (AIs) aged 50-75 residing on reservations in rural Southwestern U.S. Serial implementation refers to offering routine screening, irrespective of response to an earlier invitation, in concordance with guidelines which recommend annual FIT testing between ages 50-75. The FIT is most appropriate because it is an approved, high sensitivity fecal occult blood test and is available at Indian Health Service (IHS) and tribal health facilities where resources to provide screening colonoscopy are limited. The study is a collaborative effort between the Albuquerque Area Indian Health Board (100% Indian-owned and operated), six Pueblo Tribes in rural Southwestern U.S., and the University of New Mexico. Findings from this research could lead to an immediate increase in CRC screening and ultimately reduce CRC burden among AIs, thus addressing national and tribal priorities of reducing CRC disparities among AIs.
