PROCESS FOR MAKING FRENCH FRIED POTATOES
AND OTHER FOOD PRODUCTS
The present invention relates generally to food processing, and more particularly to a method for applying a particulate media to the outer surface of a food product, especially a french fried potato strip.
Frozen french fried potato strips are typically prepared by washing, peeling and cutting into strips whole potatoes and then blanching, parfrying and freezing the strips. ~eretofore, attenlpts have been made without much success to deposit on outer surfaces of such strips a relatively dry particulate media, such as starch, seasonings, flavor particulates or the li~e, thereby to enhance ~he flavor and texture of the product, or to create an altogether different tasting product. Such attempts have also been intended to improve the coloration of the product and to reduce its oil perception (content) when reconstituted by frying.
For example, potato strips have been dusted with a media after blanching. However J the media has not adhered well to the strips, and consequently most of the media fell off during further processing, typically during parfrying. As a subsidiary problem, the loose media contaminates the fryer.
More generally, bread crumbs have been applied commercially to food products after dipping the product in a batter to which the crumbs adhere. See, for example, Wood U.S. Patent No. 4,208,435 and Frum U.S. Patent No. 3,767,826. However, the heavy, batter-fried taste characteristic of such a product is not desirable for 12~3~ ~3 french fried potato strips and may not be desirable for other food products as well.
~ queous coatings have also been applied to food products using well known spray, slurry and enrobing techniques. For example, Roth U.S. Patent No. 3,607,313 shows a method of coating quick-frozen, discrete food pieces by spraying them with a sauce-like liquid in a tumbling drum. And, Mitan, et al U.~. Patent ~o. 3,427,951 shows a process in which a starch base slurry is used to dip or spray a food product to give it a protective film. However, such techniques inherently are not suitable for applying a relatively dry particulate media to the outer surface of a food product.
Accordingly, there is a need for a process for applying a relatively dry particulate media to the outer surface of a food product, particularly a french fried potato strip, such that the media is substantially retained on the product during processing and gives it an improved character.
It is therefore an important object of the invention to provide a process for applying a particulate media to the outer surface of a food product, such as a french-fried potato strip, such that the media is substantially retained on the product after processing.
A second important object of the invention to provide a process as aforesaid in which french fried po~ato strips processed thereby have improved characteristics.
A more specific object of the invention is to provide a process as aforesaid in which potato strips processed thereby have a crisper, more palatable suxface te~ture than prior potato strips.
~Z1~173 A further obiect of invention is to provide a process as aforesaid in which potato strips processed thereby have an enhanced flavor.
Another object of the invention is to provide a process as aforesaid in which potato strips processed thereby have a low~r oil perception than prior strips~
Still another object of the invention is to provide a process as aforesaid which causes minimal contamination to the fryer during parfrying or reconstitution.
Other objects and advantages of the invention will become apparent from the drawings and following detailed description.
In accordance with the foregoing objects, the present invention comprises a process for preparing food products such as french-fried potato strips with an adherent coating. Whole potatoes are peeled and cut into strips. The strips are impinged with a high velocity stream of particles, such as potato granules, so as to embed the particles in outer surfaces of the strips. The velocity of the stream is not so high as to damage the structural integrity of the strips. Prior to impinging, the strips may be preheated in water and chemically treated in a flume. The particle-impacted strips are preferably partially dried, steam-blanched, parfried in oil and frozen. The frozen potato strips are conventionally reconstituted, such as by baking or frying in oil. The resulting product has a crisp, golden outer surface, fluffy interior, enhanced flavor and low oil perception-~2~173 In the drawings:
" Fig. 1 is a schematic view of a particle impinging apparatus in accordance with the present invention.
In accordance with one application of the present invention, potatoes are held in storage under conventional accepted conditions, so as not to accumulate excessive amounts of sugar therein. Potatoes of the Russet-Burbank variety are preferred. The potatoes are cleaned with a water flume or spray, and then peeled in a conventional manner, using steam or a caustic solution. The potatoes are cut into sections suitably sized for french fried potato strips.
The strips are next preheated, either in water at a temperature within the range of about 150F to 190F or steam at a temperature within the range of about 190F to 220F for about 1-15 minutes. Preferably, the preheating is carried out in water at about 155F for about 5 minutes, to leach the natural sugars therein and to condition the strips. Such conditioning includes softening and moistening the strip surfaces. The preheated strips are treated in a flume containing about 0.75% Sodiumacidpyrophosphate (SAPP), a preservative and color brightener~ Other preservatives, such as SO2, HCl, or coloring agents, such as dextrose, may be added to the flume or substituted for the SAPP in a known manner.
The strips are dipped for about 10-60 seconds in the flume, and preferably for about 20 seconds As illustrated by Fig. 1, a bed of treated strips are thereafter passed on a conveyor screen under a blasting nozzle, and a high velocity stream of particles is impinged upon the strips. The particles, preferably ~LZ1~73 having a size of about 80-100 mesh, embed in outer surfaces of the strips. Particles comprising about 100 per cent potato granules, such as those sold by Basic ~merican Potato Company, Moses Lake, Washington, woxk well. Other particulate media, including potato flakes, potato flour, potato granules with nacho cheese seasoning, potato granules with tallow flavoring, or a mix of potato granules and starch, may also be used.
The potato granules are impacted against the bed of strips for about 5 to 20 seconds, and preferably for about 10 seconds, causing the strips to undergo a weight gain of about 4%. The impinging velocity of the granules must be large enough to embed or impregnate th~ granules in the outer cellular surface layers of the strips, but not so great as to destroy the structural integrity of the strips. The exit velocity of the granules as they leave the nozzle is believed to be within the range of 550 ft/sec to 750 ft/sec, and has been roughly calculated to he about 650 ft/sec. It is not known, however, whether the actual impact velocity of the granules is less or greater than the exit velocity. The high velocity of the air stream associated with the granules agitates the bed such that no one strip is subject to the impinging granules for the full 10 seconds.
The granule-impacted strips are partially dried in a dryer at a temperature within the range of about 150F to 250F to cause an estimated 10-30% moisture weight loss in the strips. Drying at about 200F for a time sufficient to cause a 20% moisture weight loss is preferred. Thereafter, the strips are steam blanched at a temperature within the range of about 190F-220F for 1~3173 about 2-10 minutes, and preferably at about 200F for about 2 minutes.
The blanched strips are then parfried in hot oil at a temperature within the range of about 340F to 380~F
for about 5-120 seconds, and preferably at about 370F for about 15 seconds. If prepared according to the foregoing parameters, the parfried strips will have a solids content of about 34-37~, including about 5-10% oils (typically about 7-8% oils). For purposes of storage and/or shipment, the strips are frozen in a conventional manner.
The frozen potato strips are reconstituted by fxying them in oil at a temperature of about 350~F for about 2-1/2 minutes, or by other conventional methocls, such as baking or heating in a microwave oven.
The embedded potato granules give the strips an unusually high solids content at their outer surfaces, thereby causing the strips to have a crisper, more palatable surface texture than prior strips and an enhanced flavor upon reconstitution.
The solids content of potato strips increases during frying through the absorption of oil and the loss of moisture from the strips. As the oil content increases due to the absorption of oil, the oil perception by the consumer also ordinarily increases. It is undesirable to have a perception of high oil content. However, strips prepared in accordance with the invention advantageously exhibit a relatively low oil content and therefore a low oil perception and less greasy character than prior products. This is due in part to the imbedded potato gxanules which seem to act as a partial barrier to the oil during parfrying, and also refrying. It is also due to a relatively short parfrying time. A longer, more ~213~73 conventional parfry is not necessary because the strips have a relatively high solids content even before parfrying, by reason of the addition of the potato granules to the surface, and hence attain the commonly preferred solids content of about 34-37% during the foreshortened parfry, as moisture is lost during parfrying.
Yet another advantage of such potato strips is that they retain their crispness longer after refry than conventionally prepared strips.
Potato granule-impacted potato strips are similar in appearance to conventional potato strips, although they "puff up" slightly during parfrying and have a slightly rougher surface texture. Electron micrographs of the strips show disruption of the outer cellular tissue with a fairly uniform embedding of potato granules therein. A
particulate media applied in this way is not likely to fall off during processing.
Referring again to Fig 1, a particle impinging apparatus 10 includes a conveyor 12 upon which a bed of potato strips are transported beneath the flow path of a nozzle 14 encased in a housing 1~. Nozzle 14, which receives potato granules from a feed line 20, is driven by an air compressor 22.
Loose potato granules which do not embed in the strips fall to the bottom of housing 10, where they are recycled by a cyclone 23 to a media feeding means 24 throuyh a line 26. Similarly, fines from cyclone 23 are filtered in a bag house 28 and returned to feeding means 24. In this way, undeposited granules are continuously recycled and thereby conserved.
Russet-type potatoes were washed, peeled and cut into strips, yielding about 5 lbs. of product. The strips :1~13~73 were conditioned slightly by preheating them in water at a temperature of about 155F for about 5 minutes, and then dipped for about 20 seconds in a flume containing about 0.75~ SAPP. The strips were next subjected to a high velocity stream of potato granules carried in air.
The granules had a size of about 80-100 mesh and were obtained from Basic American Potato Company~ A
standard handgun or blasting nozzle manufactured by Zero Manufacturing Company, Washington, Missouri, model number BNP55-7, was used. It had a #5 orifice (5/32 inch diameter opening) and a #5 nozzle (5/16 inch diameter opening). A stream flow rate of about 35 CFM at about 85 psi was used, yielding a roughly estimated nozzle exit velocity for the granules of about 650 feet per second.
The nozzle was positioned about 12 inches from the 5 lb.
product which was exposed to the stream for about 10 seconds. The potato granules embedded in outer sur~aces of the strips. The stream agitated the product to expose all the strips during that time.
The granule-impacted strips were then partially dried at a temperature of about 200F until they underwent a moisture weight loss of about 20~. The strips were steam blanched at a temperature of about 200F for about 2 minutes, parfried at a temperature of about 370F for about 15 seconds, and frozen at a temperature of about _10F .
The frozen strips were reconstit~ted by frying them in oil at a temperature of about 350F for about
