Quality evaluation of peony seed oil spray-dried in different combinations of wall materials during encapsulation and storage

Abstract

This study aimed at evaluating the performance of peony seed oil microencapsulated by spray drying during encapsulation and storage. Four different combinations of gum arabic (GA), corn syrup (CS), whey protein concentrate (WPC) and sodium caseinate (CAS) were used to encapsulate peony seed oil. The best encapsulation efficiency was obtained for CAS/CS followed by the CAS/GA/CS combination with the encapsulation ratio of 93.71 and 92.80 %, respectively, while the lowest encapsulation efficiency was obtained for WPC/GA/CS (85.96 %). Scanning electron microscopy and confocal laser scanning microscopy revealed that the particles were spherical in shape and did not exhibit apparent cracks or fissures, and gum arabic was uniformly distributed across the wall of the microcapsules. Oxidative stability study indicated that the CAS/GA/CS combination presented the best protection against lipid oxidation and the smallest loss of polyunsaturated fatty acid content among all of the formulas as measured by gas chromatography. Therefore, CAS/GA/CS could be promising materials encapsulate peony seed oil with high encapsulation efficiency and minimal lipid oxidation.

Nutritional composition, health-promoting effects, bioavailability, and encapsulation of tree peony seed oil: a review

“…In contrast, whey protein concentrate (WPC)/GA/CS and GA/β-CD only achieved encapsulation rates of 85.9% and 86.3%, respectively. 131,132 Furthermore, the TPSO-SC/GA/CS inclusion complex exhibited superior oxidative stability. 131 These findings indicate that SC/GA/CS are effective composite wall materials for encapsulating TPSO.…”

Effect of Microencapsulation Techniques on the Stress Resistance and Biological Activity of Bovine Lactoferricin-Lactoferrampin-Encoding Lactobacillus reuteri

“…Three groups of MC LR-LFCA with high survival rates were selected for analysis. The surface morphology of the microcapsules was analyzed with a field-emission scanning electron microscope (JEOL, Japan) at a voltage of 5 kV using a previously described method [ 28 ]. Images were obtained under different magnifications (10,000×, 5000×, and 2000×).…”

“…The entrapment efficiency of the microcapsules was determined as described by Shi et al [ 26 ] with slight modification. Approximately 2.0000 g microcapsule powder was added to 40 mL of petroleum ether small amplitude concussion 1 min, and then filtered.…”
