Abstract

Background: Peanuts (Arachis hypogaea L.) are widely consumed worldwide, with Brazil being a major producer. Their skins, usually discarded as processing waste, comprising about 3% of the total peanut weight, generated an estimated 1.50 Mt of waste in 2021. These skins are rich in phenolic compounds, including phenolic acids and flavonoids, with antioxidant capacities ranging from 90 to 125 mg gallic acid equivalents per gram dry weight. In this study, a phenolic-rich extract was prepared from peanut skins and used to enrich pectin- and gelatin-based candies at 0.1 and 0.2 g kg^-1. The candies underwent static in vitro digestion following the INFOGEST protocol, covering the oral, gastric and intestinal phases.

Results: Bioaccessibility of total phenolic compounds was 29.88-32.46% for 0.1 and 0.2 g kg^-1 pectin-based candies and 25.94-30.16% for 0.1 and 0.2 g kg^-1 gelatin-based candies. Regarding antioxidant activity after digestion, pectin gummy candies showed an average reduction of approximately 38%, while gelatin gummy candies exhibited a decrease of nearly 41%, measured by oxygen radical absorbance capacity. Nonetheless, the candies preserved a considerable portion of their original antioxidant capacity, even after digestion.

Conclusion: The results highlight the promising potential of using peanut skin phenolic extracts to produce antioxidant-enriched gummy candies. This approach offers a healthier alternative for consumers and promotes sustainability by valorizing abundant local agricultural by-products. Future studies could explore strategies to improve bioaccessibility, such as micro- or nano-encapsulation, and process optimization further to enhance the stability and bioavailability of these compounds. © 2025 The Author(s).

果胶和明胶糖果上的花生皮生物活性提取物：它是一种潜在的改善健康的膳食抗氧化输送系统吗？

背景：花生（arachhis hypogaea L.）在世界范围内被广泛消费，巴西是主要生产国。花生皮通常作为加工废物丢弃，约占花生总重量的3%，在2021年产生了约150万吨的废物。这些果皮富含酚类化合物，包括酚酸和类黄酮，抗氧化能力为每克干重90至125毫克没食子酸当量。在本研究中，从花生皮中制备了一种富含酚的提取物，并用于0.1和0.2 g kg-1的果胶和明胶基糖果。这些糖果按照INFOGEST方案进行静态体外消化，包括口服、胃和肠期。结果：0.1、0.2 g kg-1果胶糖的总酚类化合物生物可及性为29.88 ~ 32.46%,0.1、0.2 g kg-1明胶糖的总酚类化合物生物可及性为25.94 ~ 30.16%。对于消化后的抗氧化活性，果胶糖的抗氧化活性平均降低约38%，而明胶糖的抗氧化活性平均降低近41%。尽管如此，即使在消化后，这种糖果仍保留了相当一部分原有的抗氧化能力。结论：花生皮酚类提取物具有较好的抗氧化软糖生产潜力。这种方法为消费者提供了一种更健康的选择，并通过估价丰富的当地农业副产品促进了可持续性。未来的研究将进一步探索提高其生物可及性的策略，如微胶囊化或纳米胶囊化，并进一步优化工艺以提高其稳定性和生物利用度。©2025作者。约翰威利父子有限公司代表化学工业协会出版的《食品与农业科学杂志》。
