The invention discloses a method for producing potato flake with high dietary fiber content. The method comprises the following steps: after the byproduct of wet potato residue generated through flour-residue separation during potato starch production is subject to acid base interaction, oxidation or enzymolysis and micronization, the micronized dietary fiber of potato is mixed with mashed potatoes obtained through steaming, boiling and smashing in a certain content ratio, the mixture is dried through a roller dryer, the moisture content in the product is smaller than or equal to 10 percent, and the potato flake rich in dietary fiber is produced after crushing and sieving. The method of the invention is suitable for being implemented in whole potato processing production enterprises, the produced potato flake is rich in an excess amount of dietary fiber and can be used as an auxiliary material for processing other foods, therefore, the economic value of the byproduct of starch production, i.e., wet potato residue is greatly increased, and pollution to the environment is reduced.

The invention is directed to methods of producing ethanol and decreasing residual starch production in a no cook fermentation comprising contacting granular starch containing substrates with a granular starch hydrolyzing enzyme, a protease, and a fermenting microorganism under suitable fermentation conditions at a temperature below the starch gelatinization temperature of the starch substrate to produce ethanol, wherein the ethanol production is increased and the amount of residual starch is decreased compared to a substantially similar method conducted without the protease.

The present invention relates to methods for producing high levels of alcohol during fermentation of plant material, and to the high alcohol beer produced. The method can include selecting plant material. Selecting can include excluding plant material that has been exposed to high temperatures or that has had high moisture content.

The invention relates to the technical fields of starch production, and particularly relates to medicinal pregelatinized hydroxypropyl starch and a preparation method and use of the medicinal pregelatinized hydroxypropyl starch. The preparation method comprises the following steps: 1 pretreatment and activation of starch; 2 synthesis of hydroxypropyl starch; 3 refining of the hydroxypropyl starch; and 4 preparation and refining of pregelatinized hydroxypropyl starch. The pregelatinized hydroxypropyl starch obtained by the method is high in content of effective components, and low in impurity content; the microbial limit is controlled; and the solubleness and the freeze-thaw stability of the pregelatinized hydroxypropyl starch in cold water are greatly improved, thus achieving the medicinal grade standards.

The invention discloses a method for extracting pea molasses and pea protein isolate from pea starch production wastewater. The method comprises the steps in sequence of protein extraction, acid sedimentation separation, washing separation, neutralization, whey concentration, flash distillation for sterilization, drying and powder-sieving. The extraction method can improve the purity and yield of pea protein isolate efficiently; wastewater generated from the production of pea protein isolate is collected for extracting pea molasses for use, so that the wastewater is fully utilized, and resource waste and environment pollution are alleviated. The pea protein isolate produced by the method has the content of more than 90%, has quite high water-retaining property and oil absorption capacity, and has gel formability better than that of soybean protein isolate. The pea molasses produced by the method is a brown syrup-shaped substance with the content of total sugar within 50%-60%, and has relatively great application prospect in the aspects of foods, medicines and light industry.

The invention discloses a technology for immersing corn in a corn starch production process, wherein the technology uses a seven-can immersing method, and comprises a seventh into fragmentation grinding and a first can where new core is added, new-prepared acid is added into a sixth can before into fragmentation grinding, and concentration of sulfurous acid in the new-prepared acid is 0.15-0.17%; before the new-prepared acid is added, a can-inversing method is used, that is opposite to the direction in which the core is fed, a immersion liquid in the first to sixth cans is orderly poured form a can with a bigger sequence number to a can with a smaller sequence number, the liquid is poured until a liquid level that the immersed core is not exposed, and the immersion liquid level in each can is same; and the a total immersion time of the core is controlled in a range from 25h to 29h. The technology for immersing corn in the corn starch production process, strictly controls the immersion concentration and temperature, needs short immersion time, can effectively immerse out effective components in the corn, and has advantages of high yield, low concentration of sulfurous acid, short immersion time, and low power consumption and steam consumption.

The invention discloses a soaking process for preparing corn starch. The soaking process comprises the following steps: (1) performing primary soaking; (2) inoculating lactic acid bacteria to obtain fermentation liquor; (3) performing coarse crushing; (4) performing secondary soaking, namely adding cellulase and acid protease into the prepared fermentation liquor, keeping temperature for 4-6 hours at the temperature of 48-52 DEG C, and executing a starch production process, wherein the cellulase accounts for 0.1-0.3 percent of total weight of corn, and the acid protease accounts for 0.2-0.5 percent of total weight of the corn. In the corn soaking process, the corn soaking time can be shortened, the yield of the corn starch can be increased from about 68 percent to about 69.5 percent, and the economical benefit is remarkable.
