    摘要:

    采用不同濃度的紅酒提取物溶液(0.1、0.5,、1.0,、2.0 g/L)對(duì)南極磷蝦進(jìn)行預(yù)處理,,并以PPO活力,、TBARS值、色澤變化和感官評(píng)價(jià)為指標(biāo),,對(duì)貯藏在特定溫度條件下(2℃和25℃)的南極磷蝦抗氧化效果進(jìn)行了研究,。實(shí)驗(yàn)結(jié)果顯示,2℃和25℃條件下紅酒提取物最適質(zhì)量濃度分別為0.1 g/L和0.5 g/L,,在此條件下南極磷蝦PPO活性,、TBARS值及防黑變效果優(yōu)于其他濃度及空白對(duì)照組,可以有效地保持南極磷蝦的品質(zhì)及延長(zhǎng)貨架期,;南極磷蝦波長(zhǎng)450 nm的吸光度A450值變化和RGB值與貯藏時(shí)間呈良好的線性關(guān)系,,可以考慮用作反映貯藏條件下南極磷蝦抗氧化程度的指標(biāo)。

    Abstract:

    Influences of antioxidant on Antarctic krill during storage at 2℃ and 25℃ were investigated after pretreatment by different wine extracted solutions (0.1, 0.5, 1.0 and 2.0 g/L) in the research by testing the indexes of PPO activity, TBARS, color changes and sensory evaluation. The results exhibited that the optimal solutions of wine extracted for antioxidant effectiveness at 2℃ and 25℃ were 0.1 g/L and 0.5 g/L, respectively. Under the situation, PPO activity, TBARS value and effects of blackening protection of Antarctic krill were better than any other solutions and control group, which could maintain the quality and extend shelf life for Antarctic krill effectively. Changes of A450 value and RGB value have significant correlation with storage time, therefore, those could be considered as the right indexes to reflect the degree of antioxidant. 
