摘要:
A method of making an aldobionate product is described. The method may include providing a milk product having one or more reducing sugars, and maintaining a pH of the milk product at about 5.5 or more by adding a buffer compound to the milk product. The method may also include adding an oxidoreductase enzyme to the milk product, where at least a portion of the reducing sugar is oxidized into the aldobionate product. In addition, a method of making an aldobionate product is described that includes the steps of providing a milk product comprising a reducing sugar, mixing oxygen into the milk product, and adding an oxidoreductase enzyme to the milk product, where at least a portion of the reducing sugar is oxidized into the aldobionate product.
摘要:
The present invention relates to a composition comprising a whey protein and an active compound, wherein the composition releases at most 30 wt% of the active compound when hydrated in Jennes-Koops buffer at room temperature during a period of 30 minutes. The invention also relates to a production method for the composition. During the cheese making process this composition can be added to milk. The enzymes are then mainly released from the particle after the separation of curd from the whey has taken place.
摘要:
The inventors have used protein engineering to develop variants of fungal phospholipases. Starting from a parent phospholipase, they have modified the amino acid sequence to arrive at variants which have phospholipase activity (generally, at roughly the same level as the parent enzyme) and have a lower lipase activity on triglycerides than the parent enzyme.
摘要:
The present invention relates to a process for producing cheese from enzyme-treated cheese milk, and the use of the resulting produced cheese as ingredient in food products. More particulariy, the present invention relates to a process for producing cheese from cheese milk treated with a enzyme selected from the group of phospholipases, in particular phospholipase A 1 , A 2 and B. Also, the present invention relates to a process for stabilizing the fat emulsion of a milk composition, e.g. cream, and the use of such stabilized milk composition, e.g. for the manufacturing of UHT-cream or cream liquor.
摘要:
The present invention describes a process for making cheese, comprising: a) adding a endoprotease having a specificity for peptide bonds on the amino or carboxyl side of one or two amino acids and the ability to hydrolyze one or more bonds in the partial amino acid sequence between positions 106 and 131 in K-casein-casein to milk, b) incubating so as to partially hydrolyze K-casein-casein in the milk, and c) during or after step b) conditions causing clotting of the milk.
摘要:
The present invention provides a cheese curd that contains protein products originating from a dairy liquid containing casein and whey protein. In order to obtain the cheese curd, the dairy liquid is acted upon by a transglutaminase and a non-rennet protease, resulting in a substantial proportion of whey protein products being retained in the cheese curd. The invention also discloses a method of making the cheese curd that retains a substantial proportion of whey protein products. This invention further provides a cheese product, such as a soft cheese, a semi-soft cheese, or a hard cheese, that contains protein products originating from a dairy liquid containing casein and whey protein, and a method of making the cheese product.
摘要:
The present invention is directed to a process for producing a highly flavored cheese product in a short period of time. In the method, a mixture of cream, whole milk and non-fat dry milk is provided. The mixture has a solids content of from 45% to 55%. The mixture is pasteurized or heat treated and the temperature of the mixture is adjusted to between 85° F. (29.4° C) and 95° F. (35.0° C). A lactic acid producing culture, at least one enzyme and rennet is added to the mixture. The mixture is then fermented at a temperature of from 85° F. (29.4° C) to 95° F. for a period of time sufficient to provide a highly flavored cheese coagulum. The cheese coagulum is then heated to a temperature of from 160° F. (71.1° C) to 175° F. (79.4° C) to inactivate the culture and enzymes and to provide a highly flavored cheese product. The cheese product is cut with agitation. Thereafter, the cheese product is cooled to a temperature of from 40° F. (4.4° C) to 50° F. (10.0° C). The highly flavored cheese product has a very fine curd and can be utilized immediately in the manufacture of process cheese.
摘要:
Substantially pure chymosin is separated from rennet extracts by contacting a liquid extract with an anionic exchange medium, preferably a diethylaminoethyl (DEAE) cellulose resin packed in a liquid chromatographic column, either as a static bed or stirred bed. The rennet extract and resin are conditioned so that the resin selectively binds pepsin and chymosin passes through the resin bed and is recovered from the liquid extract from the column. The bound pepsin is periodically removed from the resin by passing a suitable eluant through the resin bed.
