BACKGROUND Red araçá is a Brazilian native species, whose fruits are rich in phenolic acids, flavonoids, anthocyanins, and carotenoids. To preserve the properties of compounds during processing, red araçá pulp (RAP) was encapsulated by hydrolyzed pinhão starch (PS), tara gum (TG), and arabic gum (AG) in different blends in equal proportions, serving as a coating material. RESULTS Fresh RAP had a gallic acid equivalent of 3098 mg per 100 g of dry weight, 156.29 μg β-carotene g-1 of dry weight, total anthocyanins of 18 mg 100 g-1 of dry weight and exhibited high antioxidant activity. The highest encapsulation efficiency achieved with the PS, TG, and AG blend was 80.4% for the total carotenoids and that for the total anthocyanins was 76% with the TG and AG blend. Only one step of antioxidant activity degradation was identified, and the carrier systems PSTG was efficient to maintain the antioxidant activity, with half-time of 23.60 - 37.27 days. CONCLUSION The use of PS alone as a coating material or associated with TG and AG gums, resulted in improved retention of the bioactive compounds, being an excellent alternative of coating material since it improved the stability of the antioxidant activity of RAP.

用水解 Pinhão 淀粉、塔拉和阿拉伯树胶制成的红色 Araçá 纸浆微胶囊化

背景红阿拉萨是巴西本土物种，其果实富含酚酸、类黄酮、花青素和类胡萝卜素。为了在加工过程中保持化合物的特性，红色阿拉萨果肉 (RAP) 被水解的 pinhão 淀粉 (PS)、塔拉胶 (TG) 和阿拉伯胶 (AG) 按等比例的不同混合物包封，用作涂层材料。结果新鲜RAP每100g干重含有3098mg没食子酸，干重156.29μgβ-胡萝卜素g-1，100g-1干重总花青素18mg，表现出较高的抗氧化活性。PS、TG 和 AG 混合物的最高包封效率对于总类胡萝卜素为 80.4%，而对于总花青素，TG 和 AG 混合物达到的最高包封率为 76%。仅鉴定了抗氧化活性降解的一步，载体系统PSTG能有效维持抗氧化活性，半衰期为23.60-37.27天。结论 单独使用 PS 作为包衣材料或与 TG 和 AG 树胶结合使用，可提高生物活性化合物的保留率，是一种出色的包衣材料替代品，因为它提高了 RAP 抗氧化活性的稳定性。本文受版权保护。版权所有。
