The aim of this work was to evaluate and study the specific proteolytic activity, antioxidant, and anti-inflammatory capacity of proteolytic extracts obtained from peel and seeds of Bromelia pinguin and Bromelia karatas, as well as the effect of encapsulation on these properties. Proteolytic extracts of by-products from B. pinguin and from B. karatas with high specific proteolytic activity were encapsulated by electrospraying with agave fructans with a high degree of polymerization. The antioxidant and anti-inflammatory capacity of the capsule was analyzed in addition to its photostability. Encapsulation efficiency was assessed using scanning electron microscopy, thermogravimetry, and differential scanning calorimetry in the capsules of B. pinguin peel extracts with its high specific proteolytic activity. The antioxidant capacity and anti-inflammatory capacity decreases when the extract was encapsulated, showing stability during storage. With regard to the photostability of the capsules, the high degree polymerization agave fructans protected the compounds. The micrographs show capsules with spherical and smooth morphology, the encapsulation efficiency was 97%, and the glass transition temperature of the capsule was 160.5°C. These results open a window of possibilities in which the use of these encapsulated by-products can be considered in the food industry as well as in the pharmaceutical industry.

这项工作的目的是评估和研究从凤梨和企鹅凤梨的果皮和种子中获得的蛋白水解提取物的比蛋白水解活性，抗氧化剂和抗炎能力，以及包封对这些特性的影响。企鹅双歧杆菌和卡拉塔斯双歧杆菌副产物的蛋白水解提取物通过用高度聚合的龙舌兰果聚糖电喷雾将具有高比蛋白水解活性的蛋白包封。除了其光稳定性之外，还分析了胶囊的抗氧化剂和抗炎能力。使用扫描电子显微镜，热重分析和差示扫描量热法评估B.pinguin胶囊中的包封效率具有高比蛋白水解活性的果皮提取物。当提取物被封装时，其抗氧化能力和抗炎能力降低，在储存过程中表现出稳定性。关于胶囊的光稳定性，高度聚合的龙舌兰果聚糖保护了这些化合物。显微照片显示了具有球形和光滑形态的胶囊，其包封效率为97％，胶囊的玻璃化转变温度为160.5°C。这些结果为在食品工业和制药工业中考虑使用这些封装的副产物打开了可能性的窗口。
