摘要:文章以感官評分為指標,優化龍蝦尾普通滲透與真空滲透處理時間,得到最優處理條件,并以新鮮蝦尾與未處理蝦尾為對照組,對最優處理條件下的普通滲透、真空滲透組蝦尾理化性能進行表征。優化實驗結果顯示,蝦尾普通滲透最優處理時間為120 min,真空滲透最優處理時間為60 min,在此條件下得到的蝦尾硬度適中、彈性較好、口感較佳。實驗結果表明,真空滲透處理蝦尾的鹽溶性蛋白含量、水分含量、離心持水率和質構最接近新鮮組,優于普通滲透處理組,且二者均優于未處理組,證明復配抗凍劑(1%復合磷酸鹽、6%海藻糖、6%山梨糖醇)浸泡對熟制蝦尾具有一定抗凍保水效果,且相較于常壓滲透處理,真空滲透的效果更佳,該研究結果可為蝦尾的常壓滲透與真空滲透工藝提供理論指導。

Abstract: In this paper, with sensory score as the index, the ordinary permeation treatment time and vacuum permeation treatment time of crayfish tails are optimized to determine the optimal treatment conditions. With fresh crayfish tails and untreated crayfish tails as the control groups, the physicochemical properties of crayfish tails in ordinary permeation group and vacuum permeation group under the optimal treatment conditions are characterized.The optimization experiment results show that the optimal ordinary permeation treatment time of crayfish tails is 120 min, while the optimal vacuum permeation treatment time of crayfish tails is 60 min. Under these conditions, the obtained crayfish tails have moderate hardness, good elasticity and good taste.The experiment results show that the salt-soluble protein content, moisture content, centrifugal water-holding ratio and texture of crayfish tails treated by vacuum permeation are the closest to those of the fresh group, and their indexes are superior to those of the ordinary permeation treatment group, and the indexes of them are both superior to those of the untreated group, which proves that soaking in compound cryoprotectant (1% compound phosphate, 6% alginate, 6% sorbitol) has a certain cryoprotective and water-holding effect on cooked crayfish tails. Moreover, vacuum permeation shows better results compared to ordinary permeation treatment. The research results can provide theoretical guidance for the atmospheric permeation and vacuum permeation processes of crayfish tails.
