Pasta samples were made by substituting wheat flour (2.5% and 7.5%) for lyophilised raspberry, boysenberry, and redcurrant and blackcurrant. Total polyphenol content showed minimum variation during processing while anthocyanins presented high degradation. In general, the first minutes of cooking showed the major detrimental effect on antioxidant activity. In vitro starch hydrolysis showed the lowest value with the addition of raspberries and boysenberries. During simulated digestion, polyphenols were released from pasta matrix reaching a 2.3‐ to 4.3‐fold increase in bioaccessible polyphenols. Likewise, values observed for reducing power and free radical scavenging activity ranged from a 0.7‐ to 2.0‐fold and 1.6‐ to 6.8‐fold increase in relation to cooked pasta, respectively. In addition, ≈40% of dialysability was observed for scavenging activity. In conclusion, enrichment of pasta with fine fruits is an effective tool to obtain a product with enhanced antioxidant potential.

浆果浓缩面食:加工和体外消化对酚类及其抗氧化活性,生物利用度和潜在生物利用度的影响

通过用小麦粉(2.5%和7.5%)代替冻干的覆盆子,波森莓,红浆果和黑加仑制成面食样品。总多酚含量在加工过程中显示出最小的变化,而花色苷则表现出高降解性。通常,烹饪的第一分钟显示出对抗氧化活性的主要有害作用。体外添加树莓和波森莓时,淀粉水解显示出最低的价值。在模拟消化过程中,多酚从面食基质中释放出来,可生物利用的多酚增加了2.3到4.3倍。同样,相对于煮熟的意大利面,观察到的降低功率和清除自由基的活性的值分别增加了0.7到2.0倍和1.6到6.8倍。此外,观察到了清除活性的约40%的可透析性。总之,富含优质水果的通心粉是获得具有增强抗氧化能力的产品的有效工具。
