低糖胡萝卜果脯加工工艺的研究
摘 要:本试验以优质的胡萝卜为材料,通过单因素试验和正交试验研究了低糖胡萝卜果脯的加工条件,确定了糖煮时起始糖液的最佳配比和收锅后糖洗的条件。结果表明:起始糖煮液的最佳配比为A1B3C3,即34%白砂糖,0.5%柠檬酸,8%蜂蜜,57.5%水;糖洗液的最佳配比为A2B3C2,按胡萝卜重加入,即24%的白砂糖,0.8%明胶,75.2%水,溶解后投料浸洗15分钟;并在45℃条件下,先烘干2小时,再在50℃~55℃的条件下烘干6小时;在常温下,真空密封保存为最好。

The Processing Technology of Low-sugar Preserved Carrot
Abstract :Useing good quality and fresh carrot as raw materials,by a single element and orthogonal experiment in the processing to determined the potimal technological conditions. Recognize sugar cooks origin sugar of the best go together with a ratio and close the condition that the pot washes after sugar . The result indicated: The outset sugar boils fluid the best allocated proportion is A1B3C3, namely 34% white granulated sugar, 0.5% citric acid, 8% honey, 57.5% water; The sugar cleaning solution's best allocated proportion is A2B3C2, joins again according to the carrot, namely 24% white granulated sugar, 0.8% gelatin, 75.2% water, after the dissolution, gets ready the materials dips 15 minutes; And under 45℃ the condition, dries first for 2 hours, then under 50℃~55℃ the condition dries for 6 hours; Under normal temperature, vacuum seal preservation for best.
