摘要: 为解决夏黑葡萄汁在贮藏过程中花色苷快速降解、色泽显著劣变等问题,本实验探究添加0.5 g/L的天然植物提取物竹叶抗氧化物(antioxidant of bamboo leaves,AOB)和葡萄籽提取物(grape seed extract,GSE)对其贮藏期内颜色、花色苷稳定性及感官品质的影响。结果表明,AOB能使葡萄汁产生显著的增色(31.6%)和红移(6.0 nm)效应,辅色效果优于GSE(增色4.2%,红移0.3 nm),并使葡萄汁颜色从宝石红色变为紫红色。在25 ℃贮藏条件下,AOB可显著延长花色苷半衰期(从12.80 d延长至15.15 d),提升颜色稳定性,而GSE会加速花色苷降解(半衰期缩短为11.36 d)。感官评价结果表明,AOB能改善葡萄汁风味,提高总体接受度,GSE则因引入酸涩味而降低感官接受度。综上,天然提取物AOB对夏黑葡萄汁具有显著辅色效果,具有较好的应用前景。本研究结果可为深色葡萄汁加工提供理论依据和技术支持。

Abstract: In order to solve the problems of rapid degradation of anthocyanins and significant color deterioration of Summer Black grape juice during storage, the effects of 0.5 g/L antioxidant of bamboo leaves (AOB), a natural plant extract, and grape seed extract (GSE) on the juice’s color, anthocyanin stability and sensory quality during storage were investigated. The results showed that AOB significantly enhanced the color (31.6%) and redshift (6.0 nm) of grape juice, the effect being more pronounced than that of GSE (4.2% enhancement and 0.3 nm redshift), and the color of grape juice changed from ruby red to purplish red after AOB addition. At 25 ℃, AOB significantly prolonged the half-life of anthocyanins (from 12.80 d to 15.15 d) and improved color stability, while GSE accelerated the degradation of anthocyanins (with the half-life shortened to 11.36 d). Sensory evaluation results showed that AOB improved the flavor and overall acceptability of grape juice, while GSE reduced the sensory acceptability due to its sour and astringent taste. In conclusion, AOB exhibits a significant co-pigmentation effect on Summer Black grape juice, indicating promising application prospects. The findings of this study provide a theoretical basis and technical support for the processing of dark grape juice.
