Effects of active alginate edible coating enriched with hydroxyapatite-quercetin complexes during the cold storage of fresh chicken fillets

Facile synthesis of hydroxyapatite nanoparticles from eggshell biowaste usingAzadirachta indicaextract as a green template

“…[6][7][8] Moreover, HANPs are also used for the removal of heavy metals from wastewater, 9,10 soil remediation, 11 catalysis, 12 column chromatography, 13,14 and food packaging applications. 15,16 The applications of HANPs are significantly influenced by particle size, shape, phase purity, crystallinity, morphology, and composition of nano-hydroxyapatite, which also depend on the synthesis precursors, synthesis routes, and processing parameters. 3,17 Therefore, there is still a great demand for developing simple, efficient, environmentally friendly, and rapid methods for the synthesis of HANPs.…”

Alginate‐based coatings charged with hydroxyapatite and quercetin for fresh‐cut papaya shelf life

“…Thanks to their biomimetic property, different authors have underlined the capability of HA crystals to be used as a delivery carrier of antimicrobial and antioxidant agents (Nocerino et al ., 2014; Fulgione et al ., 2016; Calasans‐Maia et al ., 2019; Fulgione et al ., 2019). Our previous studies have shown a very fast release of quercetin glycoside compounds from alginate‐based coatings when the bioactive compounds were complexed with HA crystals, pointing out how an edible coating enriched with hydroxyapatite/quercetin complexes could be an interesting alternative for the shelf‐life extension of fresh chicken fillets (Malvano et al ., 2022). A similar trend to the TBC was observed for yeast and mould count where the control samples had values much above the consumable limit, while among the coated samples, HA/QUE sample exhibited the lowest mould count with 3.30 log CFU g −1 .…”

“…Coating solutions were prepared in a water solution of sodium alginate and glycerol (2% w/v; Sigma Aldrich) by mixing for 2 h at 70 °C. According to Malvano et al (2022), three different sodium alginate solutions were prepared: control sodium alginate solution (SA), sodium alginate with 500 ppm of quercetin glycosides (QUE) and sodium alginate with hydroxyapatite/quercetin glucosides complexes (HA/QUE) with 500 ppm of quercetin glycosides. HA-QUE complexes were produced by adsorption method, as reported by Montone et al (2021).…”

Bioactive food coating: A review

“…Anthocyanin from other plants has also been used, such as mulberry anthocyanin incorporated into gelatin films, 106 black carrot anthocyanin in bacterial cellulose and chitosan–cellulose films, 107,108 roselle anthocyanin in starch films 109 and purple and black eggplant anthocyanin 110 . Reports have also shown that antioxidant and antimicrobial activity of films made from CMC, starch and alginate 111–113 was increased by the inclusion of quercetin.…”
