In Vitro Bioaccessibility of Bioactive Compounds from Rosehip-Enriched Corn Extrudates

Abstract

The rosehip (Rosa canina L.) fruit has gained researchers′ attention due to its rich chemical composition in vitamin C, phenols, carotenoids, and high antioxidant activity; meanwhile, polymers such as pea protein are generally recognized as exhibiting a protection role against the extrusion process. Corn snacks extrudates obtained by replacing corn flour with 10% R. canina powder (R) and 10% R. canina with pea protein (RPP) were evaluated for the physicochemical, textural, optical, and nutritional characteristics. A sample manufactured without R. canina powder was used as a control. Hardness, crispiness, chewiness, and solubility index (WSI) of the final extrudates were improved by addition of R. canina and pea protein powder (PP); meanwhile, b* (yellow/blue coordinate), C (chroma), and h* (tone) optical parameters were significantly different from the control sample (p < 0.05). Extrusion highlighted a negative impact on total phenols, carotenoids, vitamin C, and antioxidant activity extrudates, while PP exhibited a good protection against the extrusion process. In vitro digestion increased the bioaccessibility of vitamin C, folate, antioxidant activity, total phenols, and total carotenoids mainly on RPP extrudates.

In vitro gastrointestinal digestion methods of carbohydrate‐rich foods

“…Focusing on carbohydrates, among the static in vitro gastrointestinal digestion studies, from 2017 to 2023 first months (76 references), 33% of them used Infogest protocol with or without methodology variants (Egger et al., 2019 ; Igual et al., 2022 ; Iqbal et al., 2021 ; Lestido‐Cardama et al., 2022 ; Lin et al., 2021 ; Lucas‐González et al., 2021 ; Skalickova et al., 2022 ; Sousa et al., 2020 ; Varnaitė et al., 2022 ; Wei et al., 2020 ). The reported variants included a mix of RSIE with colonic fermentation (Aguirre‐Calvo et al., 2020 ; Bai et al., 2021 ; Chait et al., 2020 ; Liu, Li, et al., 2021 ), or mainly enzyme addition (Figure 5a ).…”

In Vitro Digestibility of Minerals and B Group Vitamins from Different Brewers’ Spent Grains

“…The simulated fluids contained KCl, KH 2 PO 4 , NaHCO 3 , NaCl, MgCl 2 (H 2 O) 6 , (NH 4 ) 2 CO 3 , CaCl 2 , and HCL or NaOH for the pH adjustment of the stock solutions of simulated digestion fluids. The in vitro sample digestibility (IVD%) value was calculated as the difference between the initial sample and the undigested one; the obtained result was divided by the initial mass sample and multiplied by 100, as mentioned by [23,31].…”

“…In a recent study, Igual et al showed that an in vitro digestion process based on a static in vitro method such as COST INFOGEST network could be successfully used in evaluating the bioaccessibility of some bioactive compounds from the vegetable matrix [23].…”

Investigation of Physicochemical Properties and Surface Morphology of Hydrogel Materials Incorporating Rosehip Extract

“…Rosehip extract, derived from wild roses, is a valuable natural ingredient due to its richness in vitamins, minerals and antioxidants. It is particularly known for its high content of vitamin C, which helps to brighten the skin, neutralizes free radicals and contributes to improving skin tone [19][20][21]. Polyphenols and flavonoids found in plant extracts have been associated with health benefits, including protection against diseases such as cancer, diabetes and cardiovascular problems.…”
