“…This was attributed to the hydrolysis of gallic acid from gallotannins, coumaric acid from coumarylquinic conjugates, and the hydrolysis of di- and tricaffeoylquinic acids, leading to the increased concentration of the aforesaid phenolic acids. Similar observations of enhanced bioaccessibility of aforesaid phenolic acids after gastrointestinal digestion were observed in edible Rose and Nasturtium flowers by Bortolini et al Further, the increase in the percentage bioaccessibility of TPC after the intestinal phase when compared to the gastric phase could be attributed to the interaction of digestive enzymes and the release of phenolic compounds linked to other moieties in the matrix such as proteins, carbohydrates, and fibers . In general, phenolic acids exist in the glycosylated forms in the matrix, as observed both in the present and earlier studies .…”

“…Nasturtium contained 4.71 ± 0.08 mg g –1 TAC, followed by Kachnar (2.26 ± 0.11 mg g –1 ) (Figure C). The TAC of Nasturtium observed in the present study was higher in comparison to the earlier report of Bortolini et al , who reported concentrations ranging between 0.66 and 3.79 mg cyanidin equivalents g –1 d.w. in the Nasturtium flowers of Brazil. In the case of Kachnar, the TAC content observed in the present study was 3 to 7 folds lower when compared with different Bauhinia sp., such as including B.…”

Four edible flowers commonly consumed in the Western Himalayan region, namely, Bauhinia variegata (Kachnar), Tropaeolum majus (Nasturtium), Matricaria chamomilla (Chamomile), and Tagetes erecta (Marigold), were characterized for their nutritional and phytochemical composition. Through the UHPLC-QTOF-IMS-based metabolomics approach, 131 compounds were tentatively identified consisting of phenolic acids, flavonoid glycosides, terpenoids, amino acids, and fatty acid derivatives. Kaempferol and quercetin glycosides for Kachnar, apigenin glycosides and caffeoylquinic acid derivatives for Chamomile, patulin and quercetin derivatives for Marigold, cyanidin and delphinidin glycosides for Nasturtium were the predicted marker metabolites identified through non-targeted metabolomics. Kachnar and Chamomile scored best in terms of macronutrients and essential micronutrients, respectively. Nasturtium contained high concentrations of α-linolenic acid, anthocyanins, and lutein. Kachnar contained the highest total phenolic acids (63.36 ± 0.38 mg GAE g–1), while Marigold contained the highest total flavonoids (118.90 ± 1.30 mg QUE g–1). Marigolds possessed excellent free radical scavenging and metal chelation activities. Chamomile exhibited strong α-glucosidase inhibition activity, followed by Nasturtium. The in vitro gastrointestinal digestibility of flower extracts indicated that the bioaccessibility of phenolic acids was higher than that of flavonoids. Polyphenols from Nasturtium and Chamomile showed the highest bioaccessibility. The study is an attempt to characterize traditionally consumed edible flowers and promote their wider utilization in gastronomy and nutraceuticals.

“…Phenolic compounds, characterized by molecules containing a benzene ring with at least one hydroxyl substituent, are the main examples of bioactive compounds found in products of plant origin, including teas ( Bortolini, Haminiuk, Pedro, Fernandes, & Maciel, 2021 ), fruits, and their derivatives ( Rossetto et al, 2020 , Stafussa et al, 2021 , Bortolini et al, 2022a ), edible flowers (Bortolini et al, 2022b) , and algae ( Machu et al, 2015 ). Also, flavonoids and phenolic acids are the main classes of phenolic compounds reported in Spirulina ( Table 1 ).…”

“…Jaboticaba ( Plinia cauliflora ) is native to southern Brazil. Its fruits have a spherical structure, dark skin due to the presence of anthocyanins, sweet and juicy pulp with 1–4 seeds, and grow directly on the tree's trunk (Bortolini, Barros, et al, 2022; Mannino et al, 2020). The jaboticaba seeds represent approximately 14% of the fruit and have no destination with significant economic and sustainable value.…”

“…In addition, compounds such as vescalagin, castalagin, gallic acid, (+)‐catechin, gallocatechin, and condensed tannins can also be found (Neves et al, 2021). In fruits, phenolic compounds are secondary metabolites responsible for the maturity degree, senescence, and defense against biotic and abiotic stressors (Bortolini, Barros, et al, 2022). In human health, these compounds present in jaboticaba are associated with chemopreventive properties (Holkem et al, 2020), anti‐inflammatory, hypoglycemic, hypolipidemic, and analgesic activities (da Silva Brito et al, 2021), reducing intestinal inflammation and associated endotoxemia in obesity (Rodrigues et al, 2021), among other health benefits.…”

This study aimed to evaluate the biosorption mechanisms of bioactive compounds from jaboticaba (Plinia cauliflora) seeds adsorbed on residual Saccharomyces cerevisiae. The bioaccessibility of bioactive compounds before and after the biosorption process was tested using the simulated gastrointestinal digestion technique. The biosorption process was evaluated at different solution pH values (2, 4, 6, and 8). In the present study, the biosorption occurred more favorably in an acid solution medium, and the highest adsorption capacity was found at pH 2 (qe = 49 mg g−1). In alkaline conditions (pH > 7), the biosorption was disfavored. The biosorption kinetics of phenolic compounds from jaboticaba seed extract in yeasts showed a fast equilibrium time (45 min). In addition, 80% of biosorption occurred within the first 15 min. Regarding the isotherm studies, the increased adsorption capacity observed was directly proportional to the increase in the concentration of the initial solution, presenting an L‐type curve characteristic of monolayer adsorption. The Sips and Jovanovic monolayer models suggest that the maximum adsorption capacity (q) was 75 mg g−1. According to the separation factor (RL) of the Langmuir model, the adsorption of the phenolic compounds extracted from the jaboticaba seeds occurred favorably (RL = 0.509). In addition, the concentration of total phenolic compounds after simulated gastrointestinal digestion was reduced in crude and biosorbed extracts, with bioaccessibility values of 5.37 and 2.64, respectively. However, the concentration of these total compounds increased after intestinal digestion of the biosorbed yeast. The biosorption equilibrium time was reached at 45 min, and the maximum adsorption capacity for the concentrations studied was 50 mg g−1 at pH 2. These results show that S. cerevisiae is a biosorbent capable of protecting and releasing compounds during gastrointestinal digestion and acts as a polyphenol delivery system. Novelty impact statement Yeasts biosorbed with bioactive compounds of plants can be used as a delivery system of secondary metabolites where the enriched biomass act in preserving the antioxidant and bioaccessibility of the molecules.
