American Potato Journal. The production of potato granules, a dehydrated mashed potato product, is in line with a growing trend in the processing of foods toward concentration and improved convenience for use. Several methods for producing potato granules have been developed during the past 30 years. This process involves a recycling adding back of dried potato granules and mixing the recycled material with freshly mashed potatoes to form a friable moist mixture below 40 per cent moisture content.

In between, in the silent 50s, television conveyed the dominant image of women as homemakers in such programs as The Donna Reed Show and The Loretta Young Show. Still, the TV image of the role of women is only half the story.
Many women worked out of need; for others, rising affluence and leisure freed women from household chores. In either case, women sought laborsaving devices: machines to ease drudgery and new products to simplify life. Convenience foods — aimed at making food preparation easier and quicker — became commonplace.
The interest in convenience foods merged with a change in eating habits as rising incomes meant consumers could afford more expensive foods, such as meats and fresh leafy green vegetables. This threatened many staples of the American diet such as the potato, worsening the chronic problem of overproduction. Potatoes were hardly the only crop plagued by surpluses and lower prices for producers. As early as Congress had responded by creating four regional research laboratories within the Department of Agriculture; each was charged with finding new markets and uses for regional farm commodities.
Much of the chemical engineering work at the ERRC has focused on finding ways to convert perishable commodities into stable and convenient forms. By the s a multidisciplinary team of chemists, chemical engineers, and food technologists at the ERRC zeroed in on the potato, attempting to reverse the decline in U. Declining potato consumption coupled with increased consumer demand for convenience foods prompted the search for ways of extending the shelf life of potatoes.
Ultimately, two processes emerged for producing dehydrated mashed potatoes: granules and flakes. Granules were developed first, but while they have a long shelf life, they do not re-hydrate quickly, limiting their usefulness as a convenience food. Eskew and chemical engineers James Cording, Miles J. Willard, and John Sullivan. Because the starch gelatinizes at this point, the potatoes are not sticky when reconstituted; in fact, stopping the pre-cook at the point of gelatinization is critical for preserving cell structure.
After the pre-cook, the potatoes are then cooled to stop the cooking process and further harden the cells. Cooks have long known that cooling cooked, starchy vegetables in cold water reduces their stickiness. The third and final stage is the cook done in a steam cooker. Care must be taken to avoid overcooking which would result in a rupture of the cells leading to poor texture and flavor. Cooking time varies from fifteen minutes to an hour, depending on the solids content of the potato.
Pastiness caused by cell rupture can also be mitigated if the potatoes are mashed immediately following the final cooking. Experiments at the ERRC determined that additives should be incorporated into the mash before drying to improve texture and extend shelf life.
One common additive is a dilute solution of sodium bisulfite to retard non-enzymatic browning; another is a monoglyceride emulsifier which also contains antioxidants and which helps prevent a pasty, rubbery texture. The final major step in the production of instant mashed potatoes is drying. Eventually, the researchers concluded that a single-drum drier was preferable as it yielded a denser flake that was less costly to package.
The processed potatoes come off the drum driers in a continuous sheet which must be broken into flakes before packaging. The potato flake process yielded a product with a stable shelf life which could be reconstituted into instant mashed potatoes with good texture, flavor, and aroma.
Commercial applications of the potato flake process increased demand for potatoes. In the s, consumption increased as flakes were used not only in mashed potatoes, but also in coatings, ingredients, and fabricated foods. Miles Willard, who had been instrumental in the research conducted at the ERRC, went into the private sector where he developed a new class of potato chip-like snack foods using reconstituted potato flakes. In more than 2.
Processed potato flakes have been used as rations by the U. Millions of pounds of potato flakes are purchased by the USDA annually for use in the National School Lunch Program and other domestic child nutrition and food assistance projects. By the mids research on the potato flake process was over and the commercial applications of the process were assured. This enabled researchers at the ERRC — among them, Eskew, Cording, Sullivan, and Nelson Eisenstadt — to shift their attention to developing new methods for drying fruits and vegetables.
The two most commonly employed methods — hot-air drying and freeze-drying — had limitations. Dehydrating pieces of fruit or vegetable by hot air is slow, as is the re-hydration process. The flavor of the re-hydrated pieces often is poor because of long exposure to high temperatures during drying. Freeze-dried products re-hydrate quickly and their quality is superior to the hot-air dried products, but the drying time is even slower and thus more expensive.
A third process — developed at the ERRC — incorporates explosion puffing in the dehydration process. Cording had observed that air-dried pieces of fruits and vegetables collapsed so he hypothesized that if the pieces were puffed up, this would open the inside in a honeycomb effect, making drying easier and quicker. The resulting product. The explosion-puffing process yields low-moisture — less than four percent — fruit and vegetable pieces, producing a rapidly reconstituted, high quality, and inexpensive product.
The vegetable or fruit pieces were heated while the gun rotated at a speed sufficient to tumble the pieces. Chamber pressure in the gun resulted from steam released by the heating of water in the pieces.
In the small gun the time required to obtain the requisite pressure varied from seven to fifteen minutes at which point the product exploded from the gun with a loud bang.
Soon, the process was scaled up to get reasonable cost estimates. A large commercial cereal-puffing gun was acquired to test commercial-type feed rates on large batches. The new gun produced vegetable and fruit pieces of superior color and flavor, but it was too labor intensive for commercial use. This device separated the two major functions: heating and explosion puffing. The heating is done in the main chamber by dispersing superheated steam.
The explosion puffing takes place when the discharge piston is released. This reduces the pressure in the discharge chamber from that in the heating chamber to atmospheric levels. The resulting explosion produced a better product with reduced labor costs.
CEPS was initially developed to produce dried potatoes and carrots but was later applied to apples, blueberries, pears, celery, beets, sweet potatoes, turnips, rutabagas, onions, peppers, mushrooms, and other commodities. Puffed carrots work well in quick-cooking dehydrated soup mixes where rapid re-hydration occurs and they have been marketed by companies worldwide.
Puffed potatoes are marketed as ingredients in meals for campers and for emergency rations. Success Story.

The resulting product is similar in quality to the freeze-dried version, but the re-hydration times are even faster.

Sweet potatoes are part of a trending demand for exotic and ethnic food in Europe. The consumption of sweet potatoes has more than doubled over the past 5 years and supermarkets are catering to this trend. As an exporter you can benefit but only if you are compliant with market requirements. The United Kingdom and the Netherlands are responsible for most of the European import of sweet potatoes. The sweet potato Ipomoea batatas is a root vegetable. Despite its name, the sweet potato does not belong to the same family as the potato Solanum tuberosum. There are several kinds of sweet potato with different coloured skin and flesh, for example red, orange and yellow. Europe imported , tonnes of sweet potatoes in , compared to 96, in Sweet potatoes have gained much popularity thanks to a strong promotion in Europe, especially by North American producers which also organize the International Sweet Potato Week in Europe. The United States are a strong supplier and this shows in the fast growing import figures in Europe. The import from developing countries is increasing steadily, but still far behind the dominant supply from the United States.

Food processing is the transformation of raw ingredients into food, or of food into other forms. Food processing typically takes clean, harvested crops or butchered animal products and uses these to produce attractive, marketable and often long shelf-life food products. Benefits of food processing include toxin removal, preservation, easing marketing and distribution tasks, and increasing food consistency. In addition, it increases yearly availability of many foods, enables transportation of delicate perishable foods across long distances and makes many kinds of foods safe to eat by de-activating spoilage and pathogenic micro-organisms. Processed foods are usually less susceptible to early spoilage than fresh foods and are better suited for long distance transportation from the source to the consumer. The extremely varied modern diet is only truly possible on a wide scale because of food processing.
