Description
Technical field
The present invention relates to field of noodle production.More particularly, the present invention relates to a kind of Fei Dulunmai of use raw material and produce extruding noodles and the production method thereof with pasta outward appearance and mouthfeel.
Background technology
To make raw material various due to it for noodles, and wide material sources, mode is simple, and instant, likes by consumer deeply.Divide according to forming principle, noodles can be divided into manual and machine-processed noodles.Mechanism technique can be divided into again rolling process and extrusion two kinds.Rolling process refers to that wheat flour and water are formed and has gluten structure dough under the rubbing with face equipment, dough rest, prolongs the explained hereafter such as pressure rolling sheet, slitting, drying (or freezing) packaging and goes out noodles.Extrusion by the conveying of extruder screw, shear action make material shape uniformly, institutional framework closely.
The Typical Representative of extruding noodles is pastas, and its raw material is Du Lunmai, and product color be amber, and hardness is high, the cooking afterwards product good springiness, does not tasty and refreshingly stick to one's teeth, and is mainly the consumption such as western-style restaurant, chain store, hotel.Du Lunmai is only distributed in Italy and some areas, southern Europe, the Turkey in the Near East and Syria, the Morocco in Africa and Algeria; The former Soviet Union, and the area such as the Canada in North America and northern US.China Du Lunmai resource is little, to it for raw material making pasta, a large amount of foreign exchange import need be spent, this considerably increases the production cost of pasta.Adopting Fei Dulunmai raw material to produce pasta is that domestic enterprise needs the preferential technical problem solved.
Chinese invention patent (ZL200410003491.1) describes a kind of method of form making coarse food grain face of extruding, and by controlling extrusion temperature, material water ratio etc. because of usually chain of command bar quality, it discloses, when the moisture of sample is 30%, when extrusion temperature is 80-85-90-95 DEG C, the rate of dry matter lost of noodles is minimum, is 14.95%.Its boiling water absorption rate is 70.40%.There is good cooking quality.But when the moisture of sample is elevated to 32%, the cooking quality of corn noodles has decline by a relatively large margin.
Summary of the invention
An object of the present invention is to solve at least the problems referred to above and/or defect, and the advantage will illustrated at least is below provided.
A further object of the invention is to provide a kind of extruding noodles, it adopts Fei Dulunmai raw material to produce the extruding noodles with pasta quality, solve and use Du Lunmai to produce the high problem of extruding noodles cost, and ensure that the extruding noodles produced are consistent with Du Lunmai product quality from composite material composition and technology controlling and process.
A further object of the invention be to provide a kind of regulate and control the pressure of twin (double) screw extruder extrusion chamber carry out extruding the production method of noodles, improve extruding noodles production efficiency, to obtain the pasta with better outward appearance, mouthfeel and cooking quality.
In order to realize according to these objects of the present invention and other advantage, provide a kind of extruding noodles, it is mixed by raw meal and to rub and wad a quilt with cotton and be crushed in the face that obtains; Wherein raw meal comprises wheat flour 70-75% by weight percentage, corn flour 21-23%, Gluten 3-5% and salt 1-2%; Described wheat flour is made up of the wheat of stiffness >=60, and wheat flour protein content is 14-16% whiteness >=75%, content of ashes≤0.5%; Luteole content >=5mg/kg in described corn flour, amylose content is 25-30%.
Preferably, for described raw meal adds water, mixed rubbing obtains described wadding, and the moisture content of described wadding is 25-35%.
The feature of Du Lunmai is that protein content, carotene carotene content are all higher, be respectively protein content 17-18%, carotenoid content 3-4ug/g, according to the feature of the grain variety such as Wheat in China, corn, then combination interpolation Gluten can replace Du Lunmai substantially.Such as, in Chinese Wheat Cultivars resource, grow in the wheat matter in continental arid climate district hard and transparent, higher containing protein, reach 14-16%, gluten is strong and flexible.Containing luteole in corn, with pasta appearance color comparing class seemingly.Luteole can be used as bright protective agent in free radical scavenger and food, has certain health care.Luteole is taken in and the concentration of (particularly eyes) free radical scavenger in human organ can be made to increase, and reduces the risk suffering from chronic disease.Product density can be controlled by regulation and control squeeze pressure, interpolation salt etc. and form good gluten network, reach the consistency and elasticity similar with pasta.
The raw material packet used in described extruding noodles is containing wheat, corn, Gluten, edible salt, water; Wherein said wheat is hard wheat, its stiffness >=60, and wheat flour protein content is 14-16%, whiteness >=75%, content of ashes≤0.5%; Described corn is luteole content >=5mg/kg, and amylose content is 25-30%, and after the raw material gelatinization of high amylose content cooling, its molecule can crystallization again, and the penetrating degree of extruding noodle product of making increases, and has certain pulling force.But excessively interpolation can reduce the quality of product, as poor toughness, easily broken bar; Gluten is the native protein extracted from wheat flour, can be used as flour gluten fortifier, protein content >=80% of described Gluten; Described extruding noodles use raw material packet to contain salt, absorb water and accelerate and form gluten network rapidly, can play the effect increasing muscle and regulate quality, can be good at the cooking quality of improving product owing to can make flour when salt solution and face.
