Special Issue Information

Dear Colleagues,

The current demand for foods with high nutritional and sensory quality characteristics, free from synthetic antioxidants and antimicrobials, and the rise of diseases associated with their consumption has left evidence of the need to search for their natural counterparts, which can be used as preservatives in food products and to add functional characteristics to human health. Therefore, the aim of this Special Issue titled “The Latest Research on Natural Antioxidants and Antimicrobials in Food” is to publish relevant research on natural antioxidants and antimicrobials obtained from plants, microorganisms, proteins, and other novel natural sources by using new and green technologies for their extraction. In addition, this Special Issue also welcomes innovative applications in food products to improve their performance and maintain their stability; however, it also seeks to provide beneficial effects for human health.

Abstract
The total phenolic, flavonoid, and anthocyanin contents were evaluated in 11 cultivars of Argentinian roses of different colors. HPLC-ESI-QTOF/MS was used to identify the components where ellagic and quinic acids, quercetin, and kaempferol glycosylated derivatives were found. The phenolic contents ranged from 78.8 [...] Read more.
The total phenolic, flavonoid, and anthocyanin contents were evaluated in 11 cultivars of Argentinian roses of different colors. HPLC-ESI-QTOF/MS was used to identify the components where ellagic and quinic acids, quercetin, and kaempferol glycosylated derivatives were found. The phenolic contents ranged from 78.8 ± 3.2 to 203.4 ± 3.1 mg GAE/g dw, the flavonoid content ranged from 19.1 ± 3.8 to 125.9 ± 6.5 mg QE/g dw, and the anthocyanin content ranged from less than 0.01 to 5.8 ± 0.1 mg CE/g dw. The dark red cultivars exhibited the greatest levels of the analyzed compounds and of the antioxidant activities, even higher than those of certain plants known for their high phenolic contents and antioxidant activity. Moreover, the addition of these extracts decreased the population of L. innocua and P. aeruginosa to undetectable levels 24 h after inoculation. Rose petal extracts, mainly those with a dark red color, can be used as natural additives in food, feed, and cosmetics, as they contain a high proportion of bioactive compounds with antioxidant and antimicrobial effects.
