Abstract
The oil from the heterotroph Schizochytrium is a rich source of n-3 PUFA, particularly DHA, and therefore highly susceptible to oxidation. The present work reports the first application of coaxial prilling for the protection of this oil through microencapsulation. After process optimization, core-shell microparticles were produced with calcium or zinc alginate at different concentrations. Encapsulates were analyzed in their tocopherol and PUFA content. Prilling lowered the earlier but had little effect on the latter. Microcapsules coated with calcium alginate (1 % and 1.75 %) had higher oil load and encapsulation efficiency and were therefore submitted to in vitro digestion together with a simulated meal. Digesta were also analyzed with HPLC-qTOF and 1H NMR and compared to undigested encapsulates. While 1 % calcium shell granted lower oil release and protection from oxidation in the simulated gastrointestinal tract, chromatographic and spectroscopic data of digesta showed higher presence of lipid digestion products.

Sci Rep 2024; 14:2731. [PMID: 38302772 PMCID: PMC10834431 DOI: 10.1038/s41598-024-53312-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 01/30/2024] [Indexed: 02/03/2024] Open
Abstract
Lipase inhibition is one of the directions to control obesity. In vitro assays have confirmed the inhibitory effect of selected xanthophylls, including astaxanthin, fucoxanthinol, fucoxanthin, and neoxanthin. Similarly, an in-silico study also demonstrated the successful inhibition of pancreatic lipase by astaxanthin. Unfortunately, the efficacy of these protocols in the emulsion state typical of lipid digestion remains untested. To address this issue, the current study employed the pH-stat test, which mimics lipid digestion in the gastrointestinal tract, to evaluate native and prepared sea buckthorn and rapeseed oils with varying xanthophyll contents from 0 to 1400 mg/kg oil. Furthermore, a molecular docking of zeaxanthin and violaxanthin (commonly found in plant-based foods), astaxanthin (widely distributed in foods of marine origin) and orlistat (approved as a drug) was performed. The in-silico studies revealed comparable inhibitory potential of all tested xanthophylls (variation from - 8.0 to - 9.3 kcal/mol), surpassing that of orlistat (- 6.5 kcal/mol). Nonetheless, when tested in an emulsified state, the results of pH-stat digestion failed to establish the inhibitory effect of xanthophylls in the digested oils. In fact, lipolysis of native xanthophyll-rich sea buckthorn oil was approximately 22% higher than that of the xanthophyll-low preparation. The key insight derived from this study is that the amphiphilic properties of xanthophylls during the digestion of xanthophyll-rich lipids/meals facilitate emulsion formation, which leads to enhanced fat lipolysis.

Int J Biol Macromol 2023:125548. [PMID: 37356680 DOI: 10.1016/j.ijbiomac.2023.125548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 06/05/2023] [Accepted: 06/22/2023] [Indexed: 06/27/2023]
Abstract
Ginkgo biloba extract (GBLE) contains many bioactives including flavonoids and terpene trilactones that play some pharmacological roles. These compounds are sensitive to operating conditions; so, encapsulation is a suitable approach to protect them. In this study, different carriers including maltodextrin (MD), and its combination with gum-Arabic (MD-GA), whey protein concentrate (MD-WPC), and whey-protein hydrolysate (MD-HWPC) were used to encapsulate GBLE. Powder production yield, physicochemical/functional characteristics, physical stability and flowability of particles were affected by the type and composition of carriers. FTIR results indicated the placement of phenolic compounds in the carrier matrix. The SEM images also showed the morphological changes of particles (especially the size, indentation and surface shrinkage) under the influence of various carriers. Microencapsulated powders formulated using MD-HWPC showed the highest values of TPC, DPPH, and ABTS and a lighter color which determined the suitability of this wall material (due to the improvement of surface activity and emulsifying properties of protein as a result of partial enzymatic hydrolysis) to protect the antioxidant properties of GBLE during spray-drying, improving the production yield and preserving physical and functional characteristics of the encapsulated powders.
