Embodiment 1

[0030] The invention provides a method for preparing food-grade corn fiber by a corn soaking process, the specific steps are as follows:

[0031] (1) Screen out corn that has not been moldy, weigh 100g of corn after removing impurities, put it in a beaker, add 100mL of tap water, shake for about 2 minutes, after washing, remove the washing water, and repeat washing 3 times in the same way;

[0032] (2) Transfer the cleaned corn to a 500mL ground-mouth bottle, immerse in citric acid aqueous solution with a mass concentration of 1.0%, soak for 48 hours at a constant temperature of 50°C in a closed environment, filter with filter paper, and separate corn and steeping liquid;

[0033] (3) Pour the corn obtained in step (2) into a wall breaker, add about 225mL of tap water, and crush to obtain corn slurry; put the corn slurry in a 500mL beaker, take out the upper corn germ with a colander, and then Stir the corn slurry with a glass rod until the germ is suspended, then take out th...

Embodiment 2

[0039] Compared with Example 1, the only difference is that the citric acid aqueous solution is replaced by an aqueous malic acid solution with a mass concentration of 1.0%.

[0040] After calculation, the yield of dried germ in the present embodiment is 3.85%.

Embodiment 3

[0042] Compared with Example 1, the only difference is that the aqueous citric acid solution is replaced by an aqueous lactic acid solution with a mass concentration of 1.0%.

[0043] After calculation, the yield of dried germ in the present embodiment is 3.77%.

Abstract

The invention relates to a method for preparing food-grade corn fiber through a corn soaking process. The method uses an organic acid aqueous solution with a mass concentration of 0.01% to 5.0% to soak corn, and then processes the soaked corn into corn fiber. The present invention utilizes organic acid to replace SO in the traditional process 2 Soak the corn to achieve a soaking effect comparable to the traditional soaking process, and all the products obtained are SO-free 2 residual, no need for SO removal 2 processing, saving process, green and environmental protection. The soaked corn can be directly processed into edible corn fiber. The corn fiber obtained in the present invention can extract corn fiber oil, and can also be used to prepare high dietary fiber corn germ powder, high fiber corn flakes, dietary fiber milk beverage, functional health food, food auxiliary additives, dietary fiber health care yogurt and dietary fiber cold drink Wait.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a method for preparing food-grade corn fiber through a corn soaking process. Background technique [0002] China is the world's second largest corn producer and also the world's second largest consumer. Corn, which was once limited to food and feed as the main consumption, has undergone tremendous changes. In addition to the steady growth of feed consumption, the corn deep processing industry has grown rapidly in recent years. develop. Corn is the most suitable variety of industrial raw materials among the three major food crops, and it is also the most processed food crop. The corn processing industry is characterized by large processing space, long industrial chain, and extremely rich products, including eight series of starch, starch sugar, modified starch, alcohol, enzyme preparation, condiment, medicine, and chemical industry, but mainly starch and alcohol. M...
