This research deals with the characteristics of spray-dried chia oil microcapsules formulated with different wall materials, including new encapsulant agents from chia seed (protein rich fraction, PRF; chia mucilage, Muc). The performance of six different wall materials combinations was studied: sodium caseinate and lactose (NaCas + L), NaCas and maltodextrin (NaCas + Mx), PRF and Mx (PRF + Mx), and each of the previous three with the addition of Muc. The particle size, rheology, and stability of the parent emulsions were analyzed. The characterization of the powders obtained by spray-drying the parent emulsions was carried out by their moisture content, water activity, microencapsulation efficiency, glass transition temperature, morphology, oxidative stability, and dispersibility. Emulsions were reconstituted from the powders at different storage times and analyzed by their particle size and stability. The encapsulation efficiencies were NaCas + L + Muc (96.23 ± 0.40%) ~NaCas + L (95.20 ± 0.42%) > NaCas + Mx + Muc (86.65 ± 0.27%) > NaCas + Mx (71.26 ± 0.06%) > PRF + Mx (57.74 ± 3.49%) ~PRF + Mx + Muc (53.37 ± 0.99%). The addition of Muc significantly improved the ME% in microcapsules with NaCas + Mx. The induction time values (ti) of NaCas + L, PRF + Mx and NaCas + Mx systems were about two, three, and five times higher than that of chia bulk oil, respectively. Thus, the studied wall materials were efficient to protect chia seed oil against the oxidation process.

以正大副产物为壁材的喷雾干燥正大油微胶囊的开发和表征

这项研究涉及由不同壁材料配制的喷雾干燥的奇亚油微胶囊的特性,包括来自奇亚籽的新包封剂(蛋白质富集级分,PRF;奇亚粘液,Muc)。研究了六种不同墙体材料组合的性能:酪蛋白酸钠和乳糖(NaCas + L),NaCas和麦芽糊精(NaCas + Mx),PRF和Mx(PRF + Mx),以及前三种添加Muc 。分析了母体乳液的粒径,流变学和稳定性。通过喷雾干燥母乳而获得的粉末的特征在于它们的水分含量,水活度,微囊化效率,玻璃化转变温度,形态,氧化稳定性和分散性。在不同的储存时间将乳剂从粉末中重新溶解,并通过其粒径和稳定性进行分析。封装效率为NaCas + L + Muc(96.23±0.40%)〜NaCas + L(95.20±0.42%)> NaCas + Mx + Muc(86.65±0.27%)> NaCas + Mx(71.26±0.06%)> PRF + Mx(57.74±3.49%)〜PRF + Mx + Muc(53.37±0.99%)。使用NaCas + Mx,添加Muc可以显着改善微胶囊中的ME%。感应时间值(ti)的NaCas + L,PRF + Mx和NaCas + Mx系统分别比奇亚散装油高约2倍,3倍和5倍。因此,所研究的壁材料有效地保护了奇亚籽油免于氧化过程。
