Quality, tradition and innovation.VIDEO ON THE TOPIC: How It's Made - How to Make Spaghetti and Macaroni
The present invention is directed to an improved extrusion process for producing transparent pasta and to products obtained by such process. The conventional processes for producing transparent pasta consist of a plurality of steps Figure 1 : starch and water are processed by heating or gelatinizing the starch to give a dough-like mixture. Thereafter, further starch is added, the mixture is kneaded, extruded into hot water, cooked and subsequently cooled with cold water and dried in order to obtain the end product US 6,,; US 6,,; Galvez et al.
It is disadvantageous of the previous processes that a plurality of intermediate steps and also standing times are required which significantly increase the labor and time consumption.
Several processes for producing pasta which employ extruders are known from the prior art. US 5,, deals with a process for producing starch noodles by extrusion, which comprises adding parts by weight of hot water to parts by weight of starch obtained from at least one member-selected from the group consisting of potato, sweet potato, tapioca, corn, wheat and a product thereof followed by being mixed to prepare large particles of dough and then extruding the dough under degassing at degrees of vacuum of not less than Torr to produce a dough sheet.
Starch noodles thus produced are highly transparent. EP-A discloses quick cooking pasta products which are extruded in a low temperature process by advancing a partially pre-cooked mixture of pasta flour and water prepared in a preconditioner along the length of a screw extruder through a cooking zone, then through a venting zone and a forming zone, and finally through an extrusion die to yield an extruded product.
US 5,, provides with a high temperature extrusion process for the production of legume pasta products. The process according to the invention for producing transparent pasta comprises a metering starch and water in the weight ratio of 1 When shaping the dough like mixture by a die in step c a dough-strand is obtained as product. The product can be further processed. In one embodiment of the invention, the product is dried after step c of the process.
In the process according to the invention the starch gelatinizes while heating and shearing the dough-like mixture inside the extruder.
This has the advantage that no gelatinization step is necessary after extrusion. A transparent pasta comprises according to the invention the main components starch and water which are formed into a dough-like mixture.
As further components, the pasta can also contain, for example, salt or stabilizers or other common ingredients. Transparent pasta is taken to mean products which are shaped as desired made of starch or starch mixtures and water with or without addition of other ingredients.
The transparent pasta is made into a dough, shaped, and may be further processed, e. However, the pasta is not and need not to be subjected to a fermentation or baking process. In the context of the present invention, a pasta is characterized as transparent which possesses a measurable light transmissivity and which can be determined by a transmission measurement. A basic component which can be used for the process according to the invention is starch.
Starch is a nutritionally essential component of the human and animal diet. The structural features of the starch which is contained in foods can affect the functional eg. Food compositions therefore frequently contain a starch having defined structural features which cause the desired properties of the food in question. Also, the properties of foods which contain starch- storage plant tissue eg. The polysaccharide starch is composed of chemically uniform building blocks, the glucose molecules, but is a complex mixture of different molecular forms which have differences with respect to the degree of polymerization and degree of branching, and therefore differ greatly from one another in their physicochemical properties.
A distinction is made between amylose starch, an essentially unbranched polymer of alpha-1 ,4-glycosidically linked glucose units, and amylopectin starch, a branched polymer, in which the branches come about by the occurrence of additional alpha-1 ,6- glycosidic links.
A further essential difference between amylose and amylopectin is the molecular weight. Whereas amylose, depending on the origin of the starch, possesses a molecular weight of 5x10 5 - 10 6 Da, that of amylopectin is between 10 7 and 10 8 Da. The two macromolecules can be differentiated by their molecular weight and their different physicochemical properties, which can be made visible most simply by their different iodine binding properties.
A further basic component which can be used for the inventive process is a starch mixture. Starch mixtures are taken to mean mixtures which consist of starches of various plant species, eg.
The process according to the invention is distinguished by the use of a heated extruder into which starch or a mixture of starches and water are metered. Extruders DIN are transport appliances which take in solid to viscous mixtures and express them uniformly from a shaping orifice. Extrusion processes are described, e. The main element of an extruder Figure 3 is the screw which is housed in a barrel.
This screw is driven by a drive usually an electric motor. A pumpable mixture is produced which is forced through an outlet die. There are different designs of extruders, eg. There are extruders having one, two or more screws. In the case of the extruders having two screws, a distinction is made between corotating and counterrotating twin-screw extruders. In the corotating twin-screw extruder, the screws rotate in the same direction of rotation, and in the counterrotating one they rotate in the opposite direction of rotation.
The transport and pressure buildup are caused in the single-screw and corotating twin-screw extruders by the friction of the mixture rotating with the screw at the stationary barrel wall - also termed friction transport. The mixture which thus remains in rotation is pushed to the outlet die by the helical screw flights. In the counterrotating twin-screw extruder, the principle of forced transport predominates.
As a further embodiment, a corotating extruder is used for the process according to the invention. The screw is in one embodiment subdivided into three regions having different tasks. In the rear region of the barrel there is what is termed the feed zone in which the material to be extruded is fed "feeding" , preferably via a hopper, and compacted. This is followed by the compression zone in which the material is further compacted by the reduced flight depth of the screw and the pressure necessary for discharge in the die is thereby built up.
Finally, the discharge zone ensures a homogeneous material stream to the die. The term "temperature" in this connection means the barrel temperature of the extruder. The heating is conventionally performed as jacket heating which is operated using electricity, steam, oil or hot water. In one embodiment, the extruder comprises three zones: feed zone, compression zone and discharge zone, which can be heated differently or at the same temperature.
In another embodiment, the extruder can comprise more than three zones, which can be heated differently or at the same temperature. In still other embodiments, the extruder may have only one zone or two zones. At least one of the zones is heated to a temperature which is sufficient to reach starch gelatinization. In an extruder with three or more zones, for example, at least a compression zone may be heated to a temperature which is sufficient to reach starch gelatinization.
Other zones, for example a discharge zone, may be heated to a lower temperature. The dry starting materials can be conventionally fed via a metering system which can comprise, eg. The process according to the invention, in another embodiment, is further distinguished in that the weight ratio of starch:water is 1 Depending on the starch or composition of the starch mixture used, a higher or lower amount of water may be required in order to maintain the desired processing consistency.
An exemplary embodiment of the present invention is shown in Fig. The process for producing transparent pasta comprises feeding starch and water directly to the extrusion device, and after optional air drying the extruded dough, the product is obtained Figure 2. The water can be fed in this process eg. Otherwise, other devices known to those skilled in the art for liquid metering can be used. In one embodiment of the invention, only one water feeder is used.
A further advantage of the process according to the invention is that it is a continuous process. The starch or the starch mixture is directly charged into the extruder and the water added simultaneously. Thereafter, downstream, the further processing in the extruder follows. The extruder stream passes from the feed orifice to the exit die.
Another advantage of the the process according to the invention is that it works at relative low temparatures, e. In another embodiment, the process according to the invention further comprises compacting the starch-water mixture, before degassing, by a reverse feed element.
In the process according to the invention, in this case, the degassing proceeds downstream of the reverse feed element, ie. Preferably, the degassing proceeds via application of a vacuum at approximately 0.
Another conceivable variant is, eg. After the degassing, the dough mixture exhibits greater homogeneity and fewer air inclusions. In one embodiment, in the process according to the invention, the extruder used is a multiple-screw extruder. In a further embodiment, in the process according to the invention, a single-screw extruder is used. The screw of the extruder is composed of transport elements and, optionally, also of reverse feed elements.
The screw can contain one or more kneading elements. In one embodiment, only one water feeder is used, as shown in Fig. The extruder stream passes from the feed orifice to the die.
The process according to the invention has the advantage, compared with the conventional process, that it is reduced to the metering of starch and also water into the extruder and the subsequent mechanical-thermal treatment. As a result, the production process from metering up to exit from the die on a laboratory scale takes only 15 seconds. Then, the product needs neither be heated nor quenched or cooled.
The shape of the die is not restricted and, for instance, the cross sections of the die and also the pasta produced can be, eg. The dough strand is semi-endless and, after it leaves the die, can be rolled up or cut for drying devices.
Drying can be performed in air. As an example, the drying time can be in the range of about 1 - 5 h, preferably about 2 h. Air humidity and external temperature can shorten or prolong the drying operation. Other drying processes known to those skilled in the art can also be used.
A person skilled in the art differentiates starch-storage plants such as, eg. Starch-storage plants predominantly store the starch in grains, tubers, or the legume seeds. The starch is isolated and purified in a manner known to those skilled in the art. Methods of starch extraction and purification are described, eg. In the process according to the invention, preferably, the starch or a starch mixture used is selected and extracted from, eg.
By means of the selection of these plants or their starches or starch mixtures, particularly transparent pasta may be produced. Particularly transparent pasta according to the invention is also termed "glass noodles".
The present invention is directed to an improved extrusion process for producing transparent pasta and to products obtained by such process. The conventional processes for producing transparent pasta consist of a plurality of steps Figure 1 : starch and water are processed by heating or gelatinizing the starch to give a dough-like mixture. Thereafter, further starch is added, the mixture is kneaded, extruded into hot water, cooked and subsequently cooled with cold water and dried in order to obtain the end product US 6,,; US 6,,; Galvez et al.

We developed a concept of transformative appetite, where edible 2D films made of common food materials protein, cellulose or starch can transform into 3D food during cooking. To develop these transformable foods, we performed material-based design, established a hybrid fabrication strategy, and conducted performance simulation. Users can customize food shape transformations through a pre-defined simulation platform, and then fabricate these designed patterns using additive manufacturing. Three application techniques are provided - 2D-to-3D folding, hydration-induced wrapping, and temperature-induced self-fragmentation, to present the shape, texture, and interaction with food materials. Based on this concept, several dishes were created in the kitchen, to demonstrate the futuristic dining experience through materials-based interaction design. Designing Substrate Film We fabricate substrate film that has heterogeneous density distribution, which can cause differential expansion upon hydration. In order to achieve controllable bending behavior, ethyl cellulose strips are introduced as both shape constraints and a water barriers on top of the film.
