Development for Edible Vegetable Papers from Fragrant-flowered Garlic
Abstract: The fragrant-flowered garlic was selected to be test material, edible vegetable papers from fragrant-flowered garlic was developed, of which the key technologies of protecting color, method and drying characteristics were discussed so as to provide for producing edible vegetable papers from fragrant-flowered garlic. The results showed that copper acetate solution 0.1% was the best solution for protecting color, and composite thickener CMC 0.4%, sodium alginate 1.6% and gelatin 0.2% consist of complex thickening agent, which will attain the best molding effect, at the same time, the critical moisture content of vegetable paper was 0.60 (kg/kg) and the drying time is 30 min under the drying conditions with 70℃ hot air.
