Example Embodiment

[0027] Example 1

[0028] According to the following ratio, weigh each component: 12 kg of cellulase, 25 kg of xylanase enzyme, 8 kg of β-mannanase, and 3 parts of pectinase.

Example Embodiment

[0029] Example 2

[0030] According to the following ratio, weigh the components: 10 kg of cellulase, 20 kg of xylanase, 6 kg of β-mannanase, and 4 parts of pectinase.

[0031] Under the conditions of 50°C in the soaking solution, 0.1% sulfurous acid concentration, and 0.03% compound enzyme concentration, corn is soaked for 12 hours, and the starch yield is 80.7.

Abstract

The invention discloses a composite enzyme for soaking corn starch and applications thereof. In the prior art, the sulfurous acid concentration of a soaking solution is high, the sulfurous acid water solution with a high concentration can corrode the equipment, and moreover can cause underground water pollution and trace residues of sulfurous acid in products, and thus the using effect of starch is affected. The composite enzyme comprises cellulase, xylanase, beta-mannose, and pectase. The provided composite enzyme can be used during the hydrolysis process of corns, is capable of effectively shortening the soaking time and production period and reducing the energy consumption, can reduce the soaking time of corn starch in sulfurous acid during the wet process corn starch production process, thus effectively reduces the sulfurous acid content in starch, and guarantees the starch quality. The composite enzyme has the advantages of low cost, good effect, and vast application prospect.

Description

technical field [0001] The invention relates to the field of starch processing, in particular to the field of preparing cornstarch by using enzyme preparations, in particular to a compound enzyme for soaking used for preparing cornstarch and its application. Background technique [0002] The corn starch processing industry is an important follow-up industry of agricultural products. In recent years, the starch industry has shown a sustained and good development trend. In 2010, starch production increased by 78.35% compared with the end of the "Eleventh Five-Year Plan". In 2010, the total amount of deep processing of corn nationwide was 52 million tons. In the first two years of the "Twelfth Five-Year Plan", although the growth momentum of starch production has slowed down, the deep processing of starch has shown a rapid growth trend. As an important part of the starch industry, corn starch has attracted more and more people's attention, and the industry has turned its atten...
