摘要

为探究海藻酸钠复合涂膜对鲜切荒漠肉苁蓉贮藏效果的影响。以荒漠肉苁蓉为材料,采用海藻酸钠、海藻酸钠复合涂膜浸泡处理10 min,用蒸馏水浸泡处理作为对照,在(4±1) ℃条件下贮藏12 d。对感官评价、外观品质、生理品质、褐变度、菌落总数、膜脂过氧化和抗氧化酶活性等指标进行了测定。结果表明,与对照和海藻酸钠单独涂膜处理相比,海藻酸钠复合涂膜处理可以更好地维持鲜切荒漠肉苁蓉可溶性固形物、总多糖含量,减缓色泽和硬度的下降,降低失重率和菌落总数,有效抑制丙二醛的生成和褐变度的上升。通过降低H2O2、超氧阴离子含量,抑制多酚氧化酶、过氧化物酶活性,提高超氧化物歧化酶和过氧化氢酶活性来延缓褐变,维持活性氧代谢平衡。感官评价得分和整体接受程度较高,保鲜效果良好。该研究为复合涂膜在鲜切荒漠肉苁蓉保鲜中的应用提供了理论依据。

Abstract

To investigate the effect of sodium alginate composite coating on the storage effect of fresh-cut Cistanche desertica.C.deserticola was treated with sodium alginate, sodium alginate composite coating immersion for 10 min, distilled water treated as the control group and stored at (4±1) ℃ for 12 d.Sensory evaluation, appearance quality, physiological quality, browning degree, total colony count, membrane lipid peroxidation and antioxidant enzyme activity were measured.The results showed that compared with the control and sodium alginate alone coating treatments, the sodium alginate composite coating treatment could better maintain the total soluble solids and total polysaccharide contents of fresh-cut C.desertica, slowed down the decrease of color and hardness, lowered weight loss rate and total colony count, effectively inhibited the production of malondialdehyde and the rise of browning degree.By decreasing the contents of hydrogen peroxide and superoxide anion, inhibiting the activities of polyphenol oxidase and peroxidase, and increasing the activities of superoxide dismutase and catalase to retard browning and maintain the balance of reactive oxygen metabolism.The sensory evaluation scores and overall acceptance were high, and the freshness preservation effect was good.This study provides a theoretical basis for the application of composite coating in fresh-cut C.desertica preservation.

Key words： fresh-cut Cistanche desertica; sodium alginate; composite coating; quality; storage and preservation
