胡萝卜纸的研制

Preparation of Carrot Paper

摘要:

本文研究了制作胡萝卜纸的工艺条件，包括护色、成型、干燥等条件的研究，结果表明将胡萝卜放在90 ℃的0.5%的明矾溶液中漂烫4 min护色效果最好；将CMC、黄原胶、海藻酸钠三者按照4:5:8比例混合成为复合胶粘剂，总浓度为0.6%时成型效果最好；胡萝卜浆料比为30%；并采用热风干燥方式，风速为1.0 m/s，60 ℃下干燥4~5 h，制成的胡萝卜纸不仅保持了胡萝卜的原有风味、色泽，而且纸质致密均匀，强度适中，口感良好。

Abstract:

The processing conditions for the preparation of carrot paper, including the protection of color, moulding, drying and so on, were studied. Results showed that the best protection for the color of carrot was achieved by incubating carrot in 0.5% alum solution at 90℃ for 4 min. for the moulding of carrot paper, The best ratio of CMC to xanthan gum and sodium alginate, total concentration and ratio of carrot to water were 4:5:8, 0.6% and 30%, respectively. Besides, the mixtures were dried by hot air with the wind velocity and temperature being of 1.0 m/s and 60℃, respectively. The achieved carrot paper had the original flavor, color of carrot, uniform texture and suitable strength.
