(I. Overview
Wheat bran fiber enzymatic solution contains a lot of water-soluble substances such as sugar, oligosaccharides. Using wheat bran fiber enzymatic solution, it is processed into a unique flavor of wheat tea beverage. The wheat bran material can be effectively used to reduce waste and avoid environmental pollution.
(b) Main raw materials
Wheat bran, alpha-amylase, white sugar, honey, ethyl maltol.
(III) Major equipment
Far infrared oven, constant temperature water bath, filter press.
(IV) Process flow
Wheat bran → Baking → Hot water boiling → Enzymatic treatment → Heat filtration → Filtrate → Blending → Filling → Sterilization → Cooling → Finished product
(five) operating points
1 Wheat bran screening: Bran was sieved through a 40 mesh sieve to remove impurities.
2 Baking: Place the wheat bran in a baking tray and bake it at 250-300°C until the bran color changes to a slightly yellowish brown and has a strong flavor of stir-fried wheat coke. Stop baking and it takes about 20 minutes. When baking, it is necessary to turn and bake, and must not be fried and paste carbonized.
3 boiled enzymatic hydrolysis: The baked wheat bran was weighed, according to the ratio of wheat bran to water = 1:15, boiled in boiling water for 20 minutes, cooled to 80°C, and then added 0.5% (W/W) α The amylase was hydrolyzed for 1 hour under the condition of keeping warm, so that the starch adhering to the bran was fully hydrolyzed and dissolved in water.
4 Filtration: The heat is first coarsely filtered, and the crude filtrate is finely filtered through a filter press to obtain a clear and transparent filtrate.
5 Preparation: Add 6% sugar, 2% honey, and 10 mg ethyl maltol in the filtrate.
6 Filling: Fill and seal the material liquid in time.
7 Sterilization: Sterilize with normal boiling water (100°C, 60 minutes), then cool naturally to room temperature.
