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:
A process for dried fruit preparation, which process comprises treating fruit with polygalacturonase before drying step. Polygalacturonase can be further used in combination with pectinesterase, pectin lyase, pectate lyase, xyloglucanase, beta-glucanase, amylase and lipase.
摘要:
A polypeptide having lipase activity that retains at least 80 % activity after 4 days at 20 DEG C at a pH in the range of 3.5-8, retains at least 60 % of its activity after 1 hour at 60 DEG C in acetate buffer at pH 5.0, and has an isoelectric point in the range of 3.5-4.5. The polypeptide is useful as a dough and bread quality improving agent and it reduces crumb pore diameter, increases crumb pore homogeneity and improves the gluten index in doughs. The polypeptide is derived from fungi, yeast, bacteria, plant cells or animal cells and is produced in transformed host cells including filamentous fungi, e.g. Aspergillus tubigensis.
摘要:
A method of improving the rheological properties of a flour dough and the quality of the finished product made from such a dough, comprising adding an effective amount of an oxidoreductase capable of oxidizing maltose, in particular a hexose oxidase, e.g. isolated from an algal species such as Iridophycus flaccidum, Chondrus crispus or Euthora cristata and a dough improving composition comprising the oxidoreductase.
摘要:
The present invention relates to a method of making a dough, said method comprises admixing a dough component, a phospholipase A2 enzyme which acts on N-acyl phosphatidyl ethanolamine at the sn2 position, and an enzyme that acts on a polar lipid at the sn1 position. A food enzyme composition comprising: a phospholipase A2 enzyme which is capable of acting on N-acylphosphatidyl ethanolamine at the sn2 position; and an enzyme that acts on a polar lipid at the sn1 position is also taught.
摘要:
A foodstuff containing an effective amount of: (a) a lipolytic enzyme capable of acting on a lipid substrate to liberate a free fatty acid molecule; and (b) a cyclodextrin; is disclosed. Methods of producing the foodstuff, as well as uses of a cyclodextrin for decreasing the free fatty acid content of a foodstuff incorporating a lipolytic enzyme, are also disclosed.
摘要:
Properties of starchy food products such as noodles, fried products and snack prod-ucts may be improved by treating the raw materials with a lipolytic enzyme. The enzyme treatment may improve the dough handling during processing, the texture, the crispiness, the mouthfeel and the appearance. The enzyme treatment may also reduce the oil content of a fried product, increase the firmness, and increase the bulkiness (reduce the bulk density) of a fried product. The lipolytic enzyme may have phospholipase, galactolipase and/or triacyl-glycerol lipase activity.
摘要:
Method of improving the rheological properties of a flour dough and the quality of bread, alimentary paste products, noodles and cakes wherein glycerol oxidase or a combination of glycerol oxidase and a lipase is added to the dough and dough improving compositions comprising these enzymes. The strength of (B/C ratio) and the gluten index of the dough was improved and in the resulting products the improvements were higher specific volume, increased crumb pore homogeneity and reduced average crumb pore diameter.
摘要:
The quality of a cake quality may deteriorate if the amount of eggs in the recipe is reduced. This deterioration can be counteracted by adding a phospholipase to the cake batter, as seen by an increased cake volume and improved cake properties after storage, e.g. increased cohesiveness, increased springiness, and increased elasticity. The cake quality (as measured by these parameters) can be further improved, even up to the level of the original cake, by adding a non-egg protein together with the phospholipase. Accordingly, a cake is prepared by a method, comprising: a) preparing a cake batter by mixing cake batter ingredients, said ingredients comprising non-phospholipase treated egg lecithin and phospholipase, and b) baking the cake batter to make the cake.
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.
