摘要:
The present invention relates to thermostable pullulanases useful for industrial and scientific purposes. The present invention provides methods for producing the modified pullulanase, enzymatic compositions comprising the modified pullulanase, and methods for use of the enzymatic compositions.
摘要:
This invention relates to wort making for brewing and non alcoholic beverages. More particularly it relates to methods for preparing a wort comprising a high level of free amino acids employing use of various enzymes including different exogenous proteases, for example an endoprotease and an exopeptidase.
摘要:
The present invention provides a composition comprising a polypeptide comprising or consisting of an X46 domain and further a starch degrading enzyme and uses of such composition. The polypeptide comprising or consisting of an X46 domain can boost the activity of a starch-degrading enzyme.
摘要:
Disclosed is a nucleic acid sequence obtainable from potato plants and carrying at least a portion of an isoamylase enzyme gene, together with constructs and host cells comprising the nucleic acid sequence, and methods of using the nucleic acid sequence.
摘要:
The invention concerns a novel alpha -glucosidase and a novel pullulanase obtained from a strain of the genus Thermococcus and the use for transforming a starch into a sugar syrup.
摘要:
The present invention relates to Desulfurococcus amylase and pullulanase preparations and their use in producing sweeteners and ethanol from starch.
摘要:
A method is disclosed for the expression of an active pullulanase enzyme in a microorganism host. In one aspect, a DNA construct contains a sequence encoding the pullulanase enzyme, except for the nucleotides necessary to encode the first two amino acids in mature pullulanase, and regulating sequences allowing expression of the coding sequence in a microorganism host. An advantageous DNA construct contains regulatory sequences permitting expression of the pullulanase in a yeast cell.

A method of preparing reduced fat foods is provided which employs a recrystallized and fragmented amylose precipitate. A starch having both amylose and amylopectin is gelatinized to allow preparation of pure amylose as a permeate of membrane filtration. The amylose is precipitated, recrystallized and then fragmented to form an aqueous dispersion that is useful in replacing fat in a variety of food formulations. The amylose precipitate can be derived from a starch which contains amylose, e.g., common corn starch, by gelatinizing the starch followed by precipitation of the amylose separation.

A method of preparing reduced fat foods is provided which employs a fragmented, alpha -amylase hydrolyzed amylose precipitate. Amylose is precipitated and hydrolyzed with alpha -amylase and then fragmented to form an aqueous dispersion that is useful in replacing fat in a variety of food formulations. The amylose can be derived from a native starch which contains amylose, e.g. common corn starch and high amylose corn starch, by gelatinizing the starch followed by precipitation of the amylose.
摘要:
Process of producing a grain product which comprises subjecting parboiled grain to compression by rolling the grains being maintained at temperatures prior to and during compression below gelatinization temperature. In certain cases the compression step is omitted and an improved product can be obtained by subjecting the grains to treatment with a solution containing an enzyme or enzymes, the quantity of the solution used is such that it is totally absorbed by the grain. In other cases the two aforementioned processes are combined in which cases the grain is treated with a solution containing a measured quantity of a solution containing an enzyme or enzymes the quantity of the solution is such that it is totally absorbed by the grains, thereafter the grains are subject to compression by rolling. The invention also relates to a grain product produced by said process.
