Embodiment 1

[0020] Select 50 kg of Jingtian No. 5 sweet corn, remove bracts and filaments, and thresh; soak in hot water at 70°C for 20 minutes, and the ratio of material to water should be controlled at 1:4. Put the materials into a beater for crushing and beating, boil the obtained corn syrup for 10 minutes, cool the gelatinized mash to 65°C, adjust the pH to 5.5 with citric acid, and then add 0.2% α-amylase (Novozymes) Liquefaction was carried out for 60 minutes. During this process, the enzymatic hydrolysis process parameters were optimized through a single factor test (see Table 1); the obtained corn steep liquor was boiled for 15 minutes to completely inactivate the enzyme, and the temperature was lowered to 55° C., and the pH was adjusted to 4.5 with citric acid. Add 0.05% chitosan to make the corn juice clear and transparent, and filter through 200 order nylon cloth to obtain 68.3 kilograms of sweet corn juice.

Embodiment 2

[0046] Select 50 kg of Jingtian No. 3 sweet corn, remove bracts and filaments, and thresh; soak in hot water at 70°C for 20 minutes, and the ratio of material to water should be controlled at 1:5. Put the materials into a beater for crushing and beating, boil the obtained corn syrup for 10 minutes, cool the gelatinized mash to 65°C, adjust the pH to 5.5 with citric acid, and then add 0.25% α-amylase for liquefaction for 60 minutes; Boil the obtained corn syrup for 15 minutes to completely inactivate the enzyme, lower the temperature to 55°C, adjust the pH to 4.5 with citric acid, add 0.05% chitosan to make the corn juice clear, and filter it through 200-mesh nylon cloth to obtain sweet corn Juice 85.2 kg.

[0047]Select 50 kg of red core No. 6 high-quality carrots. After selection, remove the head and tail that are not suitable for processing, wash the remaining part, peel it, cut it into small sections with a thickness of 0.6-0.7 cm, and use 0.5% citric acid + 0.5 The soluti...

Embodiment 3

[0051] Select 50 kg of Jingtian No. 5 sweet corn, remove bract leaves and filaments, and thresh; soak in hot water at 70°C for 20 minutes, and the ratio of material to water should be controlled at 1:3. Put the materials into a beater for crushing and beating, boil the obtained corn syrup for 10 minutes, cool the gelatinized mash to 65°C, adjust the pH to 5.5 with citric acid, and then add 0.2% α-amylase for liquefaction for 60 minutes; Boil the obtained corn syrup for 15 minutes to completely inactivate the enzyme, lower the temperature to 55°C, adjust the pH to 4.5 with citric acid, add 0.05% chitosan to make the corn juice clear, and filter it through 200-mesh nylon cloth to obtain sweet corn 48.2 kg of juice.

[0052] Select 25 kg of red core No. 6 high-quality carrots. After selection, remove the head and tail tip that are not suitable for processing, wash the remaining part, peel it, cut it into small sections with a thickness of 0.6-0.7 cm, and use 0.5% citric acid + 0....

Abstract

The invention relates to a preparation method of a flavor type compound sweet corn beverage, belonging to the field of food processing technology and comprising the following steps: selecting sweet corn material with the soluble sugar mass ratio of 20 percent, the juice yield more than 85 percent and soluble solids more than 10 percent and carrot material with the carotenoid content more than 16mg / 100g to obtain sweet corn juice and carrot juice; and preparing the flavor type compound sweet corn beverage by mixed blending, homogenization, desaeration, encapsulation and sterilization. The flavor type compound sweet corn beverage has unique flavor and attractive color and luster, is good for both children and adults, rich in carotene part matters and full of nutriments, not only has efficacies on invigorating the stomach to promote digestion and improving eyesight, but also has health-protection efficacies on antioxidation and cancer prevention.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a flavor type sweet corn compound beverage and a preparation method thereof. Background technique [0002] Sweet corn, also known as fruit corn and vegetable corn, is favored by consumers at home and abroad. The reason why sweet corn wins people's favor is due to its own nutritional value. Sweet corn in the milk ripening stage contains higher water-soluble polysaccharides. Usually sweet corn contains about 10-15% sugar, and is rich in amino acids, vitamins, minerals and corn oil. Therefore, edible sweet corn tastes sweet, fragrant and sticky, and is easily digested and absorbed by the human body, which has a unique health care effect. The processing and utilization of sweet corn has been widely carried out in the world, and the United States, Canada, Japan, Thailand, Taiwan Province of China, etc. are the main production and consumption places. In recent years, the prod...
