  • Patent number: 4085230
    Abstract: In abstract, a preferred embodiment of this invention is an improved roasted type peanut product and the process by which it is produced. The process includes precooking the peanuts in boiling water with a color additive ingredient, removing the peanuts and placing them in hot vegetable oil for a predetermined period of time, removing the same, coating with a light film of oil and salting the same. The product has a longer shelf life and is of a much more palatable taste than what would ordinarily be expected.

  • Patent number: 4082855
    Abstract: An elongate potato product simulating a French fry and provided with a plurality of serrated, longitudinal ridges alternating with longitudinal valleys, is formed by extrusion of a potato mix through a suitable die. The serrations of the ridges provide a multiplicity of individual projections more or less resembling spicules, which are completely exposed to hot fat during initial frying of the product prior to freezing and to applied heat during reconstitution of the frozen product. This results in French fries of superior quality. The spicules are a result of proper consistency of the mix and configuration of the extrusion die.

  • Patent number: 4005139
    Abstract: This invention relates to the continuous rehydration of dehydrated potato solids and potato mixtures to form first an homogeneous slurry which sets to a dough and the forming or shaping of this slurry or dough into products which are suitable for deep frying. The process is characterized by the improved quality of the products produced by it, and by the novel methods by which the potato solids are rehydrated and shaped or formed into pieces suitable for deep frying. The dehydrated potato solids can be either flour, flakes or granules. The dehydrated potato mixtures can be any combination of additives, binders, fillers, gums, texturizing agents and potato solids, etc., in which the potato portion constitutes at least 50% of the mixture by weight, as either flour, flakes or granules. The products can be any type of potato product, but in particular, they are deep fried potato products such as chips or French-fries.

  • Patent number: 3997684
    Abstract: A potato based food snack is prepared by mixing cooked potato solids with water and ungelatinized starch to form a dough having between about 40 percent and about 50 percent solids by weight, forming the dough into pieces, and frying the pieces in hot cooking oil. The dough contains a sufficient amount of free available gelatinized starch to cause the pieces to expand at least about 1.6 times their original dimension upon frying such that they produce a potato snack product having a porous internal structure encased in a dense exterior layer of substantially reduced porosity.

  • Patent number: 3997678
    Abstract: In the process of preparing deep-fried potato products such as chips or French fries, the conventional blanching step comprising washing and pre-heating before the actual cooking in oil is replaced by novel blanching step. In this process step, the cut potato products are submersed in water and subjected to the passage of electric current of 50-60 cycles per second supplied to the water bath by means of electrodes immersed therein, during which treatment the potato products are heated to a suitable high temperature such as the boiling point.

  • Patent number: 3991222
    Abstract: Process for making a reconstitutable dehydrated, cooked potato piece or strip. Raw potatoes are cooked and a dough of separated potato cells is formed therefrom. A small quantity of the cells are ruptured to release their starch contents. The released starch alone or in combination with additional raw starch which is gelatinized after mixing with the dough are used to give the dough an adhesive character which will permit the eventually dried potato pieces to be reconstituted in water without loss of piece identity. After rupture of the potato cells the dough is maintained in a heated condition until formed into strips or pieces of the desired size after which they are dried. An alternative process employs raw starch as the principle means for obtaining the desired adhesive character in the dried potato pieces. In the alternative process the dough is processed and formed into the desired pieces or strips without heating and thereafter the raw starch is gelatinized by application of heat.

  • Patent number: 3987210
    Abstract: A method of producing French fried potatoes from dehydrated potato granules or flakes with a binder comprising an amylose starch component and a cold-water-dispersible starch or gum component. The dehydrated potatoes and binder are combined with water to produce a dough which is formed into a desired shape and deep fat fried to produce French fried potatoes.

  • Patent number: 3968265
    Abstract: A potato dough is prepared so that it is 23 to 40% solids including cooked intact potato cells, binder and raw starch, the remainder of the dough being moisture. The dough is divided into slabs and cut into strips of normal French fry potato size. The strips are then parfried in deep fat to a moisture content in the range of 40-65% to gelatinize the starch and form a matrix surrounding the intact potato cells throughout the piece, which matrix gels upon cooling, is not thereafter disturbed and makes the product freeze-thaw stable. The product is then frozen and stored. Without loss of piece integrity the product can be finish fried directly, or even after prolonged thawing, by deep fat frying or oven heating to form a crisp French fry.

  • Patent number: 3950550
    Abstract: A fried tofu product, such as "aburage", "ganmodoki", "aburage casing" and "jointless aburage casing", is prepared without coagulants normally used in conventional processes for making tofu by forming a kneaded soy proteinaceous material or soy protein dough from a heat coagulable soy protein, shaping the protein dough into a desired shape (e.g., thin sheet, rounded disc, or tubular) and deep frying the shaped material in two successive stages. Egg components and/or edible oils or fats can be incorporated into the protein dough to improve the texture, taste and/or food value of the fried product.

  • Patent number: 3934046
    Abstract: The invention enables the production of fried potato products of greatly improved texture, flavor, and color from raw stock that exhibits excessive browning tendencies and which would normally yield fried products of excessively dark color. Typically, pieces of raw potato are pre-fried in edible oil for a short period, then leached with water. The leached pieces may be further processed in various ways, e.g., finish-fried, or par-fried and then refrigerated for distribution to the consumer or food service operator.
