Corn starch soaking prodn. process of adding vegetable protease

Abstract

The invention relates to the deeply processing of the agricultural and sideline products especially the dipping in producing method of the corn flour enzyme method. It overcomes the long marinating time, the great water and energy consumption, the SO2 befouling environment existing in the conventional damp producing method of the corn flour. The steps of the producing: firstly, the seed selection corn soak lactobacillus is fermented and cultured and is appended into the corn soak to shorten the time of reaching the effective lactic acid concentration; the corn seed albumen sops to inflate and intenerate, the cell wall is destroyed; secondly, the early dipping corn is cracked into the 4-6 petals to separate the embryo; so the better condition of permeating the lactic acid and the protease is created; thirdly, the vegetable protease is acceded to the cracked corn soak to degrading fully the protein ground substance to releasing the amylum and to shorten the dipping time.

Description

technical field [0001] The invention relates to intensive processing of agricultural by-products, in particular to a corn starch enzymatic soaking production process. Background technique [0002] At present, the wet processing process is the main process used in the production of corn starch in the world, that is, the corn is soaked and softened for 30-48 hours in the soaking solution containing sulfurous acid (0.2%-0.25%) (50±2°C) for 30-48 hours (the domestic general 40-48 hours, generally around 30 hours in foreign countries), and then through steps such as grinding, degerming, centrifugation, dehydration, and drying to obtain starch. [0003] Although this process has the advantages of high dry matter recovery rate and multiple high value-added by-products, it also has disadvantages such as long soaking time, environmental pollution, large energy consumption, and high cost, mainly in: soaking This step is the main time-delay process of the process. Domestic production ...

Problems solved by technology

However, the new enzymatic production process was adopted in production, and the examples and intellectual property rights applications of corn starch production and quality factors were considered at the same time.
