Fruits are sources of bioactive compounds (BACs), such as polyphenols. This research aimed to study the in vitro bioaccessibility of polyphenols from enriched apple snacks with grape juice and determine their antioxidant capacity. Impregnation (I) treatments were carried out at atmospheric pressure and in a vacuum (IV) at 30, 40, and 50 °C and their combinations with ohmic heating (OH), I/OH, and IV/OH. Later, samples were dehydrated by forced convection at 40, 50, and 60 °C. Enriched samples were subjected to in vitro digestion. The total polyphenols, monomeric polyphenols, and antioxidant activities were determined from recovered extracts. Results showed that total polyphenols present in higher concentrations in the gastric phase, 271.85 ± 7.64 mg GAE/100 g d.m. Monomeric polyphenols’ behavior during in vitro digestion for the VI/OH 50 °C and dried treatment (60 °C) was descending, mainly in quercetin, which decreased by 49.38% concerning the initial concentration, before digestion. The cyanin, catechin, epicatechin, and epigallocatechin decreased by 26.66%, 20.71%, 23.38%, and 21.73%, respectively. Therefore, based on obtained results, the IV/OH 50 °C treatment (dried 60 °C) is the best combination to incorporate polyphenols from grape juice.

Abstract Objectives Grapes and their 100% juices are rich sources of health promoting phenolics. Juicing of grapes includes contact with phenolic rich seeds and skins that otherwise relies on mastication for phenolic release from fruit. To understand if 100% grape juice can provide a matrix with highly bioaccessible phenolics relative to whole fruit, differences in phenolic content and bioaccessibility from commonly consumed table, Concord (CG) and Niagara (NG) grapes and their 100% juices were compared. Methods Phenolic content in CG, NG, table grapes, 100% Concord grape juice (CGJ), and 100% Niagara grape juice (NGJ) were assayed by LC-MS prior to subjecting grapes and juices to in vitro digestion to determine phenolic bioaccessibility. Results are expressed as relative and absolute bioaccessible content of individual phenolic species and total phenolics as a sum of anthocyanins (AC), flavan-3-ols (FL3), flavonols (FV), stilbenoids, procyanidins, and phenolic acids (PA). Results Phenolic compounds were concentrated in CG and NG seeds as FL3 (304.1–390.7 mg/100 g dw). CG skins were rich in AC (1050.5 mg/100 g dw) and FV (80.8 mg/100 g dw). Grape product form had a significant impact on content (P < 0.01), relative bioaccessibility, and absolute bioaccessibility (P < 0.01). CG had a higher total phenolic content (21.9–50.7 mg/100 g fw) compared to CGJ (5.8 mg/100 g fw), though NG (4.9–10.8 mg/100 g fw) was similar in phenolic content as NGJ (9.4–10.8 mg/100 g fw). Absolute bioaccessibility of CGJ total phenolics (5.2 mg/100 g fw) was similar to CG (2.6–9.6 mg/100 g fw), while NGJ (5.1–5.7 mg/100 g fw) had higher bioaccessible phenolic content than NG (0.8–1.1 mg/100 g fw). Differences in initial content and bioaccessible fractions were driven by higher relative bioaccessibility of AC in CGJ (86–135%) compared to CG (14–39%) and FL3/PA in CGJ/NGJ (48–101; 39–85%) compared to CG/NG (0–3; 9–67%). Comparisons between juices and table grapes followed similar trends. Conclusions A greater fraction of grape skin and seed derived PA, AC, and FL3 are extracted through juicing and made bioaccessible relative to whole fruit. 100% juice may provide an improved matrix for delivery of grape phenolics and despite some processing losses, whole fruit and juice are similar in overall phenolic delivery to consumers.

Efficient lipid digestion in formula-fed infants is required to ensure the availability of fatty acids for normal organ development. Previous studies suggest that the efficiency of lipid digestion may depend on whether lipids are emulsified with soy lecithin or fractions derived from bovine milk. This study, therefore, aimed to determine whether emulsification with bovine milk-derived emulsifiers or soy lecithin (SL) influenced lipid digestion in vitro and in vivo. Lipid digestibility was determined in vitro in oil-in-water emulsions using four different milk-derived emulsifiers or SL, and the ultrastructural appearance of the emulsions was assessed using electron microscopy. Subsequently, selected emulsions were added to a base diet and fed to preterm neonatal piglets. Initially, preterm pigs equipped with an ileostomy were fed experimental formulas for seven days and stoma output was collected quantitatively. Next, lipid absorption kinetics was studied in preterm pigs given pure emulsions. Finally, complete formulas with different emulsions were fed for four days, and the post-bolus plasma triglyceride level was determined. Milk-derived emulsifiers (containing protein and phospholipids from milk fat globule membranes and extracellular vesicles) showed increased effects on fat digestion compared to SL in an in vitro digestion model. Further, milk-derived emulsifiers significantly increased the digestion of triglyceride in the preterm piglet model compared with SL. Ultra-structural images indicated a more regular and smooth surface of fat droplets emulsified with milk-derived emulsifiers relative to SL. We conclude that, relative to SL, milk-derived emulsifiers lead to a different surface ultrastructure on the lipid droplets, and increase lipid digestion.
