The present invention relates to processes for separating wheat flour into two or more fractions including a gluten fraction and a starch fraction, comprising the steps of: a) mixing wheat flour and water; b) adding one or more polypeptide (s) having GH8 xylanase activity; c) incubating the mixture for a predefined period of time; d) separating the mixture into two or more fractions including a gluten rich fraction and a starch rich fraction; and e) recovering the two or more fractions including a gluten rich fraction and a starch rich fraction.

The present invention provides a system and method for extracting starch from green bananas. The system includes: a pretreatment module configured to grind and homogenize the green bananas so as to form green banana slurry; an extraction module configured to receive the green banana slurry, and configured to add an extraction solvent to the green banana slurry to generate an extracted mixture of green banana starch; a separation module, wherein the extracted mixture of green banana starch is held still in the separation module, so green banana starch precipitates and green banana suspensions are precipitated and separated; a first rinsing module configured to rinse green banana starch precipitates to remove any impurities except for the starch therein, thereby forming a banana starch cream; and, a dehydration module configured to remove water from the banana starch cream to form banana starch.

A method for preparing beer or cider concentrate including alcohol and volatile components of beer or cider flavor, and beer or cider prepared therefrom. The method includes a two step concentration method in which the first step involves a high efficiency nanofiltration that results in a highly concentrated retentate and an aqueous permeate fraction comprising alcohol and volatile flavor components. The second step involves removing water from said permeate fraction to obtain a highly concentrated alcohol solution also having volatile flavor components. The highly concentrated alcohol solution is then combined with the retentate from the first step into a final high alcohol and flavor beer or cider concentrate.

A novel dry mill process for producing pure starch, which can be used as a feed stock for bio tech processes. Corn feedstock is sent through a particle size reduction device, such as a hammer mill, to produce corn flour. The corn flour is screened into a small particle portion (which mainly contains “free” starch from the floury endosperm) and a larger particle portion (which mainly comprises the horny endosperm, germ pericarp and tip cap). The small particle potion is sent to a liquefication and a saccharification process to produce high Be corn syrup. A mud phase (mixture of oil, germ, and any light solid) is centrifuged. The light phase is sent to precoat drum filtration to produce clean corn syrup. Further, a novel wet mill process to produce starch and alcohol is disclosed. A three-section paddle screen can be used to separate starch from grit and fiber.

Disclosed is a method for improving the yield of sprayed corn bran in a corn wet-milling process, an enzyme preparation is added in the process of separating fiber from starch and protein, the fiber residue after the enzyme preparation treatment contains less water, less starch and/or protein residue, and has a looser and more fluffy structure, the yield of the sprayed corn bran in the corn wet-milling process can be remarkably improved while ensuring normal color of the finished sprayed corn bran, that is, the amount of concentrated corn soaking solution sprayed on the fiber corn bran is significantly increased.

The present disclosure discloses a method for extracting a duckweed turion starch, and belongs to the technical field of agriculture and food. The extraction method of the present disclosure includes the following steps: conducting drying and rehydration on a duckweed turion to obtain a rehydrated turion, soaking the rehydrated turion in a solvent, and then conducting washing and filtration to obtain a decolorized duckweed turion; or conducting beating on a fresh duckweed turion, soaking the fresh duckweed turion in a solvent, and then conducting washing and filtration to obtain a decolorized duckweed turion slurry; and putting the decolorized duckweed turion or the decolorized duckweed turion slurry in a dispersion liquid for extraction at a rotation speed of 6,000-18,000 rpm at 25-50° C. for 5-60 min, and then conducting filtration, centrifugation, washing and drying to obtain the duckweed turion starch. The turion starch obtained by using the method of the present disclosure has a high purity and a high extraction rate. The purity reaches 93% or above with the highest purity of 96.54% or above. The extraction rate reaches 85% or above.
