Antioxidant, antimicrobial activity and mineral composition of low-temperature fractioning products of Malus domestica Borkh (common Antonovka)

Abstract

The low-temperature fractionation of fruit Malus domestica Borkh (Common Antonovka) has been performed. We obtained by fractionation the biologically active products that are the dehydrated concentrate of juice and the powder of pomace fibers. Use of low temperature minimizes biological value losses during processing. These fractions of fruit Malus domestica Borkh (Common Antonovka) are experimentally studied. It is found that the fractions have high antioxidant activity and include bioflavonoids and organic and phenol carboxylic acids. Analysis of chromatograms showed availability of the identical compounds in the products of low-temperature fractionation. Sodium and potassium are part of the cells of biological systems as highly mobile ionic forms. Therefore, these elements prevail in the concentrated juice. Iron, manganese, copper, and zinc are biogenic trace elements or components of enzyme systems and are evenly distributed as in plant cell walls as well in protoplasm. It follows from the results of the study of the mineral composition that the products of the low-temperature fractioning can be used for a functional food as a result of its high content of magnesium and iron. The low-temperature fractionation of fruit Malus domestica Borkh (Common Antonovka) has antimicrobial activity against the standard strains of spoilage:

Fruit waste: a current perspective for the sustainable production of pharmacological, nutraceutical, and bioactive resources

“…Apple pomace contains flavonoids, phenolic acids, carotenoids, and anthocyanins that have various anti-microbial and anti-viral activities ( Kuznetsova et al, 2017 ; Barreira et al, 2019 ; Zardo et al, 2021 ). Polyphenolic bioactives from apple pomace showed antimicrobial activity against Paenibacillus larva (American foulbrood in honeybees) ( Giménez-Martínez et al, 2020 ).…”

“…Polyphenolic bioactives from apple pomace showed antimicrobial activity against Paenibacillus larva (American foulbrood in honeybees) ( Giménez-Martínez et al, 2020 ). Lipophilic compounds from different species of Malus (apple pomace) consist of saturated, unsaturated, and polyunsaturated fatty acids, along with polyphenols, phytosterols, and four homologs of tocopherol were found to exhibit inhibitory effects on the growth of a few Gram-positive and Gram-negative bacterial cultures such as Escherichia coli, Pseudomonas aeruginosa , Enterococcus faecalis , Streptococcus pyogenes, Bacillus cereus , Micrococcus luteus , Bacillus subtilis , and Staphylococcus aureus ( Table 2 ; Alberto et al, 2006 ; Fratianni et al, 2011 ; Zhang et al, 2016 ; Kuznetsova et al, 2017 ; Radenkovs et al, 2018 ; Zardo et al, 2021 ). Phenolic compounds isolated from different extraction solvent varies in antimicrobial activities ( Zhang et al, 2016 ; Zardo et al, 2021 ; Santos et al, 2022 ).…”

“…Recently, Chen et al (2023) demonstrated that grape seed proanthocyanidins extract inhibits dengue virus (DENV) replication by reducing COX-2 expression by modulating NF-κB translocation and ERK/P38 MAPK signaling pathways (Table 3; Chen et al, 2023). et al, 2006;Fratianni et al, 2011;Zhang et al, 2016;Kuznetsova et al, 2017;Radenkovs et al, 2018;Zardo et al, 2021 Hydro-ethanolic Shehata et al, 2021;Hasan et al, 2022;Cebi and Erarslan, 2023;Meryem et al, 2023;Saleem et al, 2023 Pear peels and pulp Chlorogenic acid, arbutin, malaxinic acid, oleanolic acid, rutin, ursolic acid, epicatechin, and procyanidin B2 Joshi et al, 2015;Pasqua et al, 2016;Zhang et al, 2018;Oh et al, 2022;Pascual et al, 2022; Several bioactive phytochemicals, such flavonoids, phenolics, alkaloids, anthocyanins, and tannins are abundant in pomegranates. It shows a broad spectrum of anti-microbial activity against various pathogenic and multidrug-resistant bacterial strains.…”

Comparison of Old and Local Apple Varieties and Seedlings (Malus domestica Borkh.) in the Variability of Some Morphological Characters of Fruits and Seeds

“…Regarding polyphenols, it is known that old and local apple varieties were characterized by a higher content of polyphenols and stronger antioxidant properties than commercial varieties, which enjoys a high growth rate, but unfortunately, these new varieties are characterized by a very low content of bioactive compounds, including polyphenolic compounds (Kuznetsova et al, 2017;Oszmiański et al, 2019). The consumption of such apple varieties may reduce the polyphenolic compounds in the dietary supply (Iacopini et al, 2010;Donno et al, 2012).…”
