Ketchup Industry-Processing and Production
I.INTRODUCTION History of Ketchup Ketchup, a tangy, seasoned tomato sauce, is one of America's favorite condiments. Although ketchup, also spelled catsup, is used primarily as a relish for hamburgers, hot dogs, and French fries, it is also a common ingredient for sauces, meatloaf, beans, and stews. During the mid-1990s the sales of ketchup exceeded $400 million annually. The tangy sauce originated in ancient China as a brine of pickled fish or shellfish called "ke-tsiap." Neighboring countries adopted their own variations of "kechap" consisting of fish brine, herbs, and spices. In the late 1600s, English sailors visiting Malaysia and Singapore were so impressed with the sauce that they took samples home. English cooks attempted to duplicate the spicy sauce, but without access to some of the exotic Asian ingredients, they improvised with cucumbers, mushrooms, nuts, oysters, and other variants. One hundred years later, New Englanders created the definitive tomato ketchup when Maine seamen returned from Mexico and the Spanish West Indies with seeds of an exotic New World fruit called tomato. The tangy tomato ketchup quickly became a popular sauce for codfish cakes, meat, and other foods. Making ketchup at home was a tedious, day-long process. The tomato mixture, cooked in heavy iron kettles at wood-burning stoves, required constant stirring to prevent it from burning. Scouring the preserving kettles meticulously was also no easy task. To
the relief of many homemakers, ketchup became commercially available in the second half of the 1800s. H.J. Heinz Co. developed one of the first leading brands of mass-marketed ketchup. The classic narrow-neck design of the Heinz ketchup bottle established the norm for the industry. The narrow-neck bottle simplified pouring the ketchup and minimized contact with air, which could darken the sauce. Glass was an ideal container because it was inert and did not react with the ketchup, and the clear glass allowed the consumer to see the product. Initially, the bottles were sealed with cork, dipped by hand into wax to prevent aeration, and topped with foil to further protect it from contamination. By the turn of the century, screw caps provided a more convenient closure. In the 1980s, plastic squeezable containers revolutionized ketchup packaging and soon outsold glass containers. Plastic was not only more convenient than glass for pouring the thick sauce, but also safer. Ten years later, in response to environmental concerns, recyclable plastic containers were also developed.

The history of ketchup and the history of advertising are inextricably intertwined. This is especially true in the case of the H.J. Heinz Company, a firm that pioneered many elements of the prepared food business and the modern advertising industry.
Born in 1844, Henry John Heinz began helping his mother with her gardens along the Allegheny River, just east of Pittsburgh, when he was nine years old. He learned business practices while working as a bookkeeper for his father's brickyard and at night school. By his teens he was employing three women to help process garden products and bottling his mother's horseradish for distribution. Heinz distinguished his horseradish from his competitors by using clear glass bottles to emphasize the product's purity.
Twenty years later, Heinz was operating another family food processing firm. Riding the New York elevator one day in 1892, he saw a sign advertising 21 varieties of shoes. He took the concept, came up with a figure of 57 because he thought it was a memorable number, and created the catch phrase "Heinz 57 Varieties."
In 1893, seeking to bolster attendance at the World's Columbian Exposition in Chicago, Heinz distributed thousands of small tokens throughout the fair grounds. The tokens were redeemable for a free Heinz souvenir, a watch charm in the shape of a pickle, at the food pavilion, which was soon overrun with visitors. The "pickle pin" went on to become one of the best-known corporate souvenirs in history, with over 100 million distributed.
In 1898, Heinz bought the Iron Pier in Atlantic City, New Jersey, renamed it the Heinz Ocean Pier, and operated it until 1945 as a free public attraction with antique displays, lectures, concerts, and motion pictures amid the displays of Heinz products and souvenirs. (William S. Pretzer)
II. THE PRODUCT Banana Ketchup Banana ketchup or banana sauce is a popular Philippine condiment
mashed banana, sugar,
and spices. Its natural colour is brownish, so it is often dyed red to resemble tomato ketchup. Banana ketchup was made when there was a shortage of tomato ketchup during World War II, due to lack of tomatoes and a comparatively high production of bananas. Filipino food technologist Maria Y. Orosa (1893– 1945) is credited with inventing a banana ketchup recipe.
Physical Properties Tangy. The flavour of the sauce is usually tangy or there is a mixture of sweet and spicy taste. Consistency. This refers to the ability of the ketchup to retain its liquid in suspension. Colour. Traditionally, the color of the ketchup is red, where the basis for the color of the ketchup is the fruit used for making it, tomato.
Chemical Properties pH. Acidity of ketchup preserves the sauce. Concentration. The amount of solids used in the production of the ketchup. They are recognized as Grades A through C with its specific concentration.
Uses and Application Banana ketchup is a type of condiment used to enhance the flavour of the food. In Filipino households, this ubiquitous condiment is used usually on foods especially dry dishes like - omelettes (torta), hot dogs, burgers, fries, fish and other meats. But for some other applications, banana ketchup is also a vital and distinct ingredient in Filipino-style spaghetti (sweeter than the traditional Italian spaghetti). There is also a "hot" version made by the same company (Jufran). It still has a hint of sweetness, coupled with spicyhot taste. It is exported to countries where there is a considerable Filipino population (United
States, Canada, United
France, Switzerland, Australia and New Zealand). Today, more and more food dishes were invented for the efficiency and satisfaction of the tastes of the Filipinos. Now, ketchups are one of the seasonings of the main dishes for its unique blend of sweetness and spice that is perfectly matched with these foods. For Filipino dishes, examples for them are Menudo, Caldereta, Meat balls with Sauce, Escabeche, etc.
Availability and Cost In the Philippines, at the time of World War II, the demand for ketchup was very high where there were lacks of tomatoes and the availability of the production of bananas were comparatively high. With the help of the Filipino food technologist, Maria Y.Orosa (1893- 1945) found a way to overcome this crisis. She invented Banana Ketchup with the same flavour and taste of the Tomato Ketchup that traditionally used by the people at that
time. Therefore, as time flows, more and more banana ketchup production and industries were developed. With great abundance of the availability of the bananas here in the Philippines having a tropic climate where bananas can grow well at this environment, plus the spices being used for making banana ketchup can help the manufacturing industry to lessen the cost of its product. For homemade banana ketchup, about 200 Php will be spent for 2.5 L of banana ketchup.
Product Safety The quality of ketchup is insured by taking samples of the product during various stages of production. Tomato growers must comply with regulations set by the Environmental Protection Agency and the Food and Drug Administration regarding the use of fertilizers and pesticides. Increasing concern in the closing decades of the 20th century led to increased use of natural fertilizers and pesticides. Inspection is necessary of the tomatoes, ingredients, and of all processing equipment which comes into contact with the product.
Oxidation of ketchup can darken the color of ketchup, but de-aeration of the sauce during manufacture can prevent this problem. However, once the containers are opened, oxidation may still occur. Although the acidity of ketchup preserves the sauce, manufacturers recommend that once containers are opened they should be refrigerated to prevent deterioration of the ketchup color, flavor, and quality.
To maintain consistency in color and flavor, manufacturers determine the concentration of tomato solids in the mixture, since about one-third of the ketchup's acidity and sugar content depends on the amount of solids. The ketchup Grades A through C must conform to specific concentrations. The quality of the ketchup can be measured by its physical consistency, or body, which refers to the ability of the ketchup to retain its liquid in suspension. The slower the rate, the higher the grade of the ketchup. For instance, the Bostwick Consistometer, recommended by the USDA, set Grades A and B at flow rates at less than 4 inches (10 cm) in 30 seconds at 68°F (20°C).

II. RAW MATERIALS The main ingredients of ketchup are tomatoes/bananas, sweeteners, vinegar, salt, spices, flavorings, onion, and/or garlic. The types of sweetener used are usually granulated cane sugar or beet sugar. Other sweeteners include dextrose or liquid sugar in the form of corn or glucose syrup. The white vinegar, commonly 100-grain distilled, helps to preserve the ketchup. The spices commonly used to enhance the flavour of the tomatoes are allspice, cassia, cinnamon, cayenne, cloves, pepper, ginger, mustard, and paprika. Some manufacturers believe that whole spices produce a superior, more mild flavour than ground spices or spice oils. More modern processes use premixed or encapsulated spices, which are easier to use but more expensive. Whatever the form, spices must be of a high quality. The various brands of ketchup have slightly different formulas, which vary primarily in the amounts of spices or flavorings. Thicker consistencies require a greater ratio of sugar and spices relative to the tomato juice. Occasionally formulas must be slightly adjusted according to variations in the acid and sugar content of tomatoes, which occurs with changes in growing conditions and types of tomatoes.
Material Safety In accordance to the product safety standards, the general preferences of using banana fruit (saba) is strictly followed. The sterility of the working place is very important in the manufacturing of the banana ketchup in order to avoid contamination of the product and its high quality. The quality of banana alters the taste and quality of the product. III. MANUFACTURING PROCESS Industrial Scale ( Tomato Ketchup Production Process )
Developing quality tomatoes
1. Ketchup manufacturers must seek out the best quality tomatoes for their product. Tomato varieties are developed which are superior in color, flavor, texture, and yield. Consistency is an important factor, as slight variations in tomato characteristics could alter the flavor and color of the finished product.
2. Tomatoes are harvested mechanically between June and July. The fruit is commonly conveyed by water from the trucks into a flume, or an inclined channel. The water method washes the tomatoes and protects them from bruising while they pass from the truck to the factory. The U.S. Department of Agriculture or state inspectors approve and grade tomatoes to meet initial requirements. The
tomatoes are sorted, washed, and chopped. Next, precooking, or scaling, in stainless steel vats preserves the tomatoes and destroys bacteria.
3. The chopped and precooked tomatoes are pumped into pulping machines, or cyclones, which separate seeds, skins, and stems from the pulp. The pulp and juice are filtered through screens and processed further into ketchup, though some may be stored in a paste for use later in the year.
Adding ingredients and cooking
4. The pulp is pumped into cooking tanks or kettles and heated to boiling. Foaming may occur if fresh tomato pulp is used, but can be corrected with antifoaming compounds or compressed air. Precise amounts of sweeteners, vinegar, salt, spices, and flavorings are added to the tomato pulp. Most spices are added early in the cooking process. To avoid excessive evaporation, volatile spice oils and vinegar must be mixed in later. Onions and garlic can be mixed in with the spices, placed in a separate bag, or chopped and added to the pulp. Salt and sugar may be added at any stage of cooking though it is better to add sugar later to prevent burning. The mixture cooks for 30-45 minutes and is circulated by rotating blades installed in the cookers. The temperature must be carefully regulated to insure absorption of the ingredients without overcooking, which creates a flat body.
5. Once the cooking is complete, the ketchup mixture passes through a finishing machine. Finishers remove excess fiber and particles through screens, creating a smoother consistency. The ketchup passes to a holding tank before further processing.
6. The ketchup may be milled at higher temperatures and pressures to achieve a smoother consistency.
7. The ketchup must be de-aerated to prevent discoloration and growth of bacteria. Excess air might also create unattractive air pockets and impede the closure process.
8. To prevent contamination, the ketchup passes from the receiving tanks to the filling machines at a temperature not lower than 190°F (88°C). The containers are filled with the ketchup and immediately sealed to retain the freshness of the product. Ketchup containers come in various sizes and shapes, including 14-oz. bottles, No. 10 cans, pouch packs, room-service sizes, and single-serve packets.
9. The containers must be cooled to prevent flavor loss through stack burning, which occurs when ketchup stays at high temperatures after cooking is complete. Containers of ketchup may be cooled in cold air or cold water.
Labeling and packing
10. Finally, the ketchup containers are labeled and coded with product information, including ingredients, date and location of manufacture, and shelflife. The bottled ketchup may be inspected again before shipping. The entire process of ketchup manufacturing generally takes two to three hours.
Traditional Making of Tomato Ketchup at Industrial Scale
Present way of Making Tomato Ketchup
Ketchup manufacturers continue to improve the quality of ketchup by developing tomato strains that are superior in color, flavor, and firmness. Tomato hybrids are also engineered to improve resistance to disease and rot, thus decreasing the reliance on chemical pesticides.
In the 1990s, in response to consumer demand for more healthful foods, ketchup manufacturers created low-calorie, low-salt ketchup alternatives. The increasing popularity of Spanish salsas and marinades also influenced manufacturers to develop salsa-style ketchups which were lower in sugar content. Packaging technology continues to improve as consumers demand safer, more convenient, and recyclable containers.
