摘要:
The present invention relates to combinatorial variants of a parent glucoamylase that have altered properties for reducing the synthesis of condensation products during hydrolysis of starch. Accordingly the variants of a parent glucoamylase are suitable such as for use within brewing and glucose syrup production. Also disclosed are DNA constructs encoding the variants and methods of producing the glucoamylase variants in host cells.
摘要:
A method for the in situ production of an emulsifier in a foodstuff, wherein a lipid acyltransferase is added to the foodstuff. Preferably the emulsifier is produced without an increase or without a substantial increase in the free fatty acid content of the foodstuff. Preferably, the lipid acyltransferase is one which is capable of transferring an acyl group from a lipid to one or more of the following acyl acceptors: a sterol, a stanol, a carbohydrate, a protein or a sub-unit thereof, glycerol. Preferably, in addition to an emulsifier one or more of a stanol ester or a stanol ester or a protein ester or a carbohydrate ester or a diglyceride or a monoglyceride may be produced. One or more of these may function as an additional emulsifier.
摘要:
This invention relates to polypeptides, more specifically amylase polypeptides and nucleic acids encoding these, and their uses e.g. as non-maltogenic exoamylases in producing food or feed products.
摘要:
The present invention relates to methods for reducing color and/or unpleasant taste and/or malodor development in a composition comprising at plant material, such a cereal bran, in particular during solubilization processes of the plant material. The invention further relates to optimised methods of solubilization, wherein color and/or unpleasant taste and/or malodor development is controlled. Solubilised plant material, kit of parts, the use of such solubilised plant material, e.g. in food products or bioethanol are also encompassed by the present invention.
摘要:
The present invention relates to a chromatographic separation process for fractionating betaine-containing solutions by utilizing fractions comprising parts of the separation profile as a substituent of the eluent in a novel and inventive manner. The process provides improved separation capacity and separation efficiency without affecting the yield or purity of betaine or other products. The process can especially be applied to sequential SMB separation systems.
摘要:
The present invention provides a composition, and a process for preparing and method for using such a composition. The composition comprises (i) a surface coating material; and (ii) (ii) a cross-linked enzyme crystal or cross-linked enzyme aggregate wherein the enzyme is cross-linked with a multifunctional cross-linking agent and wherein the cross-linked enzyme crystal or cross-linked enzyme aggregate has an antifouling activity or generates an antifouling compound. Suitably the composition may be used to inhibit biofilm formation.
摘要:
A method of producing one or more of a carbohydrate ester, a protein ester, a protein subunit ester or a hydroxy acid ester, which method comprises admixing an acyl donor, an acyl acceptor and water to produce a high water environment comprising 5-98% water, wherein said acyl donor is a lipid substrate selected from one or more of the group consisting of a phospholipid, a lysophospholipid, a triacylglyceride, a diglyceride, a glycolipid or a lysoglycolipid and said acyl acceptor is selected from one or more of the group consisting of a carbohydrate, a protein, a protein subunit, or a hydroxy acid; and contacting the admixture with a lipid acyltransferase, such that said lipid acyltransferase catalyses one or both of the following reactions: alcoholysis or transesterification.
摘要:
The present invention relates to the solubilisation of cereal bran, for preparing compositions comprising soluble fractions of cereal bran and the use of these compositions comprising solubilised cereal bran for the preparation of food products, such as bread.
