The objective of this study was to explore the influence of nanocellulose type (nanocrystalline cellulose (NCC) and nanofibrillated cellulose (NFC)) and concentrations (0.05-0.20%, /) on the physicochemical properties, microstructure, and in vitro digestion of β-carotene loaded emulsions and β-carotene bioaccessibility. The optimum conditions for the formation of stable β-carotene loaded emulsions were found when NCC was used as a stabilizer at a concentration of 0.2% /. This was due to the rod-shaped structure of NCC, which led to more stable emulsions with smaller droplet size and reduced flocculation. During the in vitro gastrointestinal digestion, NFC emulsions at increased concentrations were found to retard free fatty acid (FFA) release from the emulsions and reduce the bioaccessibility of β-carotene. On the other hand, NCC emulsions at concentrations of 0.2% / promoted lipolysis and demonstrated highest β-carotene bioavailability. Hence, these emulsions could be used for the delivery of β-carotene with potential applications in the development of functional foods and nutraceuticals.
本研究的目的是探讨纳米纤维素类型（纳米晶纤维素（NCC）和纳米纤丝化纤维素（NFC））及其浓度（0.05 - 0.20%，/）对负载β-胡萝卜素乳液的物理化学性质、微观结构、体外消化以及β-胡萝卜素生物可及性的影响。当使用浓度为0.2% / 的NCC作为稳定剂时，发现形成稳定的负载β-胡萝卜素乳液的最佳条件。这是由于NCC的棒状结构，其导致乳液更稳定，液滴尺寸更小且絮凝减少。在体外胃肠道消化过程中，发现浓度增加的NFC乳液会延缓乳液中游离脂肪酸（FFA）的释放并降低β-胡萝卜素的生物可及性。另一方面，浓度为0.2% / 的NCC乳液促进脂肪分解并表现出最高的β-胡萝卜素生物利用度。因此，这些乳液可用于递送β-胡萝卜素，在功能性食品和营养保健品的开发中具有潜在应用。
