Embodiment Construction

[0011] Raw material pretreatment: choose fresh ears of black corn with black color, no impurities, six or seven mature ears, after cleaning, centrifugal dehydration and crushing, the fineness is not less than 80 mesh, or soak in warm water for 2 to 3 hours, and grind with a refiner pulp.

[0012] Gelatinization: Mix according to the ratio of material to water 1:10, heat and boil for 20 minutes.

[0013] Liquefaction: Add 1% α-amylase to black corn steep liquor and keep warm at 90°C to 95°C for 20 minutes.

[0014] Saccharification: After cooling, adjust the pH value to be slightly acidic, add glucoamylase at a ratio of 0.1%, and keep warm at 55°C to 60°C to fully saccharify until there is no iodine reaction. The whole process takes about 4 to 5 hours.

[0015] Filtration: The saccharified liquid is coarsely filtered with a diatomaceous earth filter while it is hot, and then finely filtered with a cardboard filter.

[0016] Adjustment: add 8% to 10% granulated sugar, a small ...

Abstract

The invention discloses a technology for processing a black corn milk beverage. The technical scheme is that the technology comprises the following steps of: selecting fresh black corncobs which are black, impurity-free and 60 to 70 percent mature, cleaning, performing centrifugal dehydration, crushing until the fineness is not less than 80 meshes, mixing materials and water in a ratio of 1: 10, heating and boiling for 20 minutes, adding 1 percent of alpha-amylase into black corn steep liquor, keeping the temperature at the temperature of between 90 and 95 DEG C for 20 minutes, cooling, adjusting the pH value until the solution is slightly acid, adding 0.1 percent of saccharifying enzyme, keeping the temperature at 55 to 60 DEG C to ensure that the solution is fully saccharified, roughly filtering a hot saccharified liquid by using a kieselguhr filter, finely filtering by using a sheet filter, adding 8 to 10 percent of granulated sugar, transferring correction liquor into a high-pressure homogenizer, homogenizing under the pressure of 20MPa, sterilizing at the temperature of 100 DEG C for 6 to 8 minutes, and bottling at the temperature of between 70 and 75 DEG C.

Description

Technical field: [0001] The invention relates to a beverage processing technology, more specifically to a black corn milk beverage processing technology. Background technique: [0002] As a kind of corn, black corn is generally used as food or feed. In recent years, as people love miscellaneous grains, black corn has also become a kind of food that is loved by people, but it is generally fresh food, with additional value is also lower. Invention content: [0003] Choose black corn fresh ears with black color, no impurities, six or seven mature ears, after cleaning, centrifugal dehydration and crushing, the fineness is not less than 80 mesh, mix according to the ratio of material to water 1:10, heat and boil for 20 minutes, put in black corn steep liquor Add 1% α-amylase, keep warm at 90°C-95°C for 20 minutes, adjust the pH value to slightly acidic after cooling, add 0.1% glucoamylase, keep warm at 55°C-60°C to make it fully saccharified, The saccharified solution is coar...
