We offer multi-layered noodles that contain high-amylose wheat flour, have good shape retention and separation, and are less prone to becoming crumbly. [Solution] Multi-layer noodles having a laminated structure with layer B disposed between two layers A, wherein the content of high-amylose wheat flour in the total mass of cereal flours and starches in layer A is X% by mass, and the content of high-amylose wheat flour in the total mass of cereal flours and starches in layer B is Y% by mass, where X>Y and 5≦X≦100, and the high-amylose wheat flour is wheat flour with an amylose content of 40% by mass or more in total starch as analyzed by the Concanavalin A method.

A working process for beating the Handmade Soba is classified into water circulation, rolling and cutting. To solve the problem that the most important and hard work is water circulation and buckwheat without water circulation is bad taste. This watering work is a hard work. If this work can be abolished, the effort of the soba making can be reduced, and anyone can easily beat beside.SOLUTION: The need for water circulation can be eliminated by replacing a necessary amount of water required for water circulation with a gelled liquid obtained by pregelatinizing cereal flour, buckwheat flour, starch, flour, refined rice flour, top-grade rice flour, or the like, a colloidal liquid, and a soft drink made from sugars, salts, and high-fructose corn syrup, and mixing the soft drink with buckwheat flour for 20 to 30 seconds. The amount of water required at this time is 50 to 60% by weight with respect to the flour.SELECTED DRAWING: None.

The application belongs to the technical field of polymer materials, and discloses a design method of multifunctional hydrogel based on a rare earth-starch system.The hydrogel specifically comprises starch (potato starch / wheat starch / corn starch), acrylamide, polyvinyl alcohol, silver nanowires and europium ions.The hydrogel has a fluorescent and conductive double channel, overcomes the disadvantage of traditional rare earth hydrogel which can only be used as a fluorescent sensor, and provides a stronger network by physical crosslinking of the rare earth-starch, so that the mechanical properties are enhanced; meanwhile, the hydrogel can freely adjust the mechanical properties and the fluorescent intensity by changing the starch content and respond to the external ion environment, and has a very high sensing sensitivity (GF = 9.02) and mechanical properties (strain = 1377%); the dynamic response time can reach 52 ms.The hydrogel sensor has stable performance and is convenient to prepare, widens the application range of the rare earth hydrogel, and has a good development prospect.

The invention relates to the technical field of gene engineering and enzyme engineering, and particularly provides an alkaline amylase mutant F178A with improved enzyme activity as well as a preparation method and application of the alkaline amylase mutant F178A. The mutant is obtained by replacing 178th-site phenylalanine (Phe) of an amino acid sequence as shown in SEQ ID NO: 1 with alanine (Ala), and the amino acid sequence of the mutant is as shown in SEQ ID NO: 3. Compared with wild-type Ano amylase, the mutant has the advantages that the enzyme catalysis efficiency is obviously improved, the specific enzyme activity to soluble starch, corn raw starch, wheat raw starch and cassava raw starch is higher than that of the original enzyme, and meanwhile, the excellent properties such as the optimum temperature (70 DEG C), the optimum pH (8.0) and the thermal stability of the mutant are completely reserved. Molecular simulation shows that mutation increases the volume of an active pocket and is beneficial to substrate binding and product release. The mutant provided by the invention has wide application prospects in the industrial fields of textile desizing, starch saccharification, biofuel production and the like.

We offer semi-fresh noodles that don't dissolve easily when boiled and have a firm texture. [Solution] Semi-fresh noodles having a moisture content of more than 15% by mass and 28% by mass or less, wherein the raw material flour for the semi-fresh noodles contains 20 to 100% by mass of high-amylose wheat flour in the total mass of grain flour and starch, and the high-amylose wheat flour is wheat flour in which the amylose content in the total starch, as analyzed by concanavalin A method, is 40% by mass or more.

The invention discloses a garment processing marking method, a substance and a preparation process, the garment processing marking method comprises a substance A, a substance B and a substance C, the substance A, the substance B and the substance C are mixed at normal temperature according to the weight ratio of 2: 2: 1 to form a marking substance, the substance A is clear water, the substance B is starch, and the substance C is starch. The starch is one or more of sweet potato starch, cassava starch, corn starch, wheat starch, rice starch, potato starch and mung bean starch; the substance C is a mixture composed of fatty alcohol-polyoxyethylene ether sodium sulfate, alkyl glycoside, fatty alcohol-polyoxyethylene ether, sodium chloride, sodium citrate, sodium benzoate, sodium xylene sulfonate and deionized water; according to the fabric marking device, fabric can be marked conveniently, the marked fabric is not prone to falling off and being eliminated, the stability is good, subsequent processing of the fabric is facilitated, meanwhile, the fabric cannot be affected in the marking process, and subsequent cleaning and processing are also quite convenient.
