Method for extracting proteins and functional lipid from soybean liquid by directional continuous catalysis with nano magnetic immobilized enzymes

The present invention relates to fields of continuous directional catalysis of soybean slurry to extract protein and functional oil with nano-magnetic immobilized enzymes. The present invention discloses soybean slurry as raw material and continuous mobile phase, and nano-magnetic immobilized enzymes as stationary phase applied in three-phase magnetic fluidized bed. The present invention provides a method of enzymatic disrupting cell walls by nano-magnetic immobilized enzyme cocktail including cellulose, pectinase and alkaline protease. The method can he used to break down lipoprotein, lipopolysaccharide complex and break lipoprotein film on the surface of lipoprotein to release the lipid. The present invention also provides a method to catalyze phospholipid using nano-magnetic immobilized phospholipase to change the polarity of phospholipids and control liquid emulsification phenomenon. The enzymes disclosed in the present invention do not interfere with each other. The preparation method can be used to catalyze soybean slurry continuously using the nano-magnetic immobilized enzymes to extract protein and functional lipid simultaneously.

NUCLEIC ACID MOLECULE ENCODING GLE1 PROTEIN VARIANT WITH INCREASED PHYTIC ACID SENSITIVITY AND USE THEREOF
20180119166 · 2018-05-03 ·

Provided are a nucleic acid molecule encoding a Gle1 protein variant comprising a phytic acid-binding pocket, a protein encoded by the nucleic acid molecule and a method using the nucleic acid molecule. The Gle1 protein variant has an increased sensitivity to phytic acid in plants, and also has an effect of highly increasing vegetative growth, seed yield, seed performance and abiotic stress tolerance in plants containing a low level of phytic acid. Therefore, high yield low-InsP.sub.6 crops may be cultivated using the nucleic acid molecule.

Method for producing wheat glutamine peptide

The present invention discloses a method for producing wheat glutamine peptide using wheat gluten powder as raw material, belonging to the fields of food and biotechnology. The method includes the steps of: performing enzymolysis in two steps using Alcalase and papain with the wheat gluten powder as raw material, to obtain the wheat glutamine peptide with components with molecular weight of less than 1000 Da being more than 90%, characteristic glutamine peptide segment glutamine-arginine-glutamine (Gln-Arg-Gln, QRQ) content being more than 2.0% and glutamine content being up to 23.54% by treating the enzymatic hydrolysate by centrifugation, ultrafiltration, concentration, spray drying, etc. The produced glutamine peptide can be used as functional nutrition composition ingredient in the development and production of ordinary foods, health foods and medicines.
