Probiotics and proanthocyanidin-rich cinnamon extract (PRCE) have numerous potential health benefits, but they are very sensitive to degradation in various environmental conditions. Additionally, the combination of these two materials into a single structure could possibly enhance their therapeutic properties. Thus, the aim of this study was to produce and evaluate the solid lipid microparticles covered by electrostatic interactions of polymers in which Lactobacillus paracasei (BGP1) and Bifidobacterium animalis subsp. lactis (BLC1) were either encapsulated alone or co-encapsulated with PRCE. Through turbidimetric titration and zeta potential measurement, the optimum coacervates were obtained at a pH of 4.2 with the protein:polysaccharide mixing ratio of 6:1. Along with quantification of the probiotics, total phenolic compounds, and proanthocyanidins, morphological and physicochemical characterizations were performed during storage for 120 days at both 7 and 25°C. All the produced powders had similar morphological and physicochemical properties. The treatments with BLC1 and 5% PRCE presented greater encapsulation efficiencies for probiotic, phenolics, and proanthocyanids with 98.59% ± 0.45, 119.49% ± 4.21, and 81.25% ± 1.9, respectively. Additionally, there was greater viability for BLC1 (9.30 ± 0.16 log CFU / g) after 120 days of storage at 7°C. In conclusion, solid lipid particles with BLC1 and 5% PRCE are a promising solution for the preservation and consumption of both materials.

益生菌和富含原花青素的肉桂提取物（PRCE）具有许多潜在的健康益处，但它们对各种环境条件下的降解非常敏感。另外，将这两种材料组合成单个结构可能会增强其治疗性能。因此，本研究的目的是生产和评估被副干酪乳杆菌（BGP1）和动物双歧杆菌亚种的聚合物静电相互作用覆盖的固体脂质微粒。乳酸菌（BLC1）可以单独封装，也可以与PRCE共封装。通过比浊滴定和ζ电位测量，在pH为4.2的条件下，蛋白质与多糖的混合比为6：1可获得最佳凝聚层。除了对益生菌，总酚类化合物和原花色素的定量分析外，还在7和25°C下储存120天的过程中进行了形态和理化表征。所有生产的粉末具有相似的形态和物理化学性质。BLC1和5％PRCE的处理对益生菌，酚类和原花色素的包封效率更高，分别为98.59％±0.45、119.49％±4.21和81.25％±1.9。此外，在7°C下储存120天后，BLC1具有更高的生存力（9.30±0.16 log CFU / g）。结论，
