Special Issue Information

Dear Colleagues,

Phenolic compounds are well known for their antioxidant and free-radical-scavenging abilities, as well as their different health properties, including anti-inflammatory, antitumor, and hypoglycaemic properties, among others. Due to these countless positive effects on human health, researchers have intensified their study with the aim of discovering food matrices rich in this class of phytochemicals or agro-industrial residues that can be used as sources of phenols. Moreover, different kinds of products can be functionalized with this class of phytochemicals. Indeed, phenolic compounds have been extensively investigated for their possible applications in the food industry for improving the shelf life of perishable products. In fact, phenols are also able to exert antimicrobial activities, through their capacity to slow the microbial invasion in some products and avoid the putrefaction of others, mainly in fruits and vegetables. For this reason, several bio-based and synthetic polymers are being functionalized with phenolic compounds to prolong shelf life when used directly in contact with the food matrix through combined strategies. However, in food applications, phenolic compounds could be influenced by other food components, processing, and storage conditions. The use of phenolic compounds from natural sources in food is an interesting opportunity for the application and exploitation of their biological activities and allows the production of food without synthetic additives for consumers. This is because the current concern about the impact of food on health is that it influences consumer choices of food based on its formulation. In addition, the distribution and content of phenolic compounds in plant-based food products depend on multiple parameters, such as geographical areas, variety, and manufacturing practices. Thus, the contents of phenolics can be exploited as a source of analytical data to establish product classification and solve authenticity issues. Several analytical techniques have been developed for the extraction and analysis of phenolic compounds. The focus of this Special Issue is to collect and discuss conventional and innovative analytical techniques for food phenolics investigations, their possible applications as food preservatives or functional ingredients for the development of functional food and active food packaging, as well as food classification and authentication studies.

Chenopodium quinoa Willd. is rich in phenolic compounds and exhibits diverse biological activities. Few studies have focused on the effect of colored quinoa’s phenolic profile on potential biological activity. This study used a UPLC–MS/MS-based metabolomic approach to examine the quinoa phenolics and their association with in vitro antioxidant and hypoglycemic properties. In total, 430 polyphenols, mainly phenolic acids, flavonoids, and flavonols, were identified. Additionally, 121, 116, and 148 differential polyphenols were found between the white and black, white and red, and black and red comparison groups, respectively; 67 polyphenols were screened as shared key differential metabolites. Phenylalanine, tyrosine, and the biosynthesis of plant secondary metabolites were the main differently regulated pathways. Black quinoa had better total phenolic contents (643.68 mg/100 g DW) and antioxidant capacity, while white quinoa had better total flavonoid contents (90.95 mg/100 g DW) and in vitro α-amylase (IC50 value of 3.97 mg/mL) and α-glucosidase (IC50 value of 1.08 mg/mL) inhibition activities. Thirty-six polyphenols, including epicatechin and linarin, etc., were highly correlated with in vitro antioxidant activity, while six polyphenols, including tiliroside and chrysoeriol, etc., were highly correlated with in vitro hypoglycemic activity. This study may provide important information for colored quinoa resources to develop their healthy food applications. Full article
