Ketchup (also spelled catsup or catchup), also known as tomato ketchup, tomato sauce, red sauce, Tommy sauce, Tommy K, or dead horse, is a condiment, usually made from tomatoes. The ingredients in a typical modern ketchup are tomato concentrate, spirit vinegar, corn syrup or other sugar, salt, spice and herb extracts (including celery), spice and garlic powder. Allspice, cloves, cinnamon, onion, and other vegetables may be included.
Ketchup started out as a general term for sauce, typically made of mushrooms or fish brine with herbs and spices. Some popular early main ingredients included blueberry, anchovy, oyster, lobster, walnut, kidney bean, cucumber, cranberry, lemon, celery and grape. Mushroom ketchup is still available in some countries, such as the UK, and banana ketchup is popular in the Philippines.
Ketchup is often used with chips (French fries), hamburgers, sandwiches and grilled or fried meat. Ketchup with mayonnaise forms the base of Thousand Island dressing and fry sauce. Ketchup is also typically used as a base for barbecue sauce.
As the century progressed, tomato ketchup began its ascent in popularity in the United States, influenced by the American enthusiasm for tomatoes. Tomato ketchup was sold locally by farmers. A man named Jonas Yerks (or Yerkes) is believed to have been the first man to make tomato ketchup a national phenomenon. By 1837 he had produced and distributed the condiment nationally. Shortly thereafter, other companies followed suit. F. & J. Heinz launched their tomato ketchup in 1876. Heinz tomato ketchup was advertised: "Blessed relief for Mother and the other women in the household!"
The Webster's Dictionary of 1913 defined "catchup" as a "table sauce made from mushrooms, tomatoes, walnuts, etc. [Written also ketchup]."
Modern ketchup emerged in the early years of the 20th century, out of a debate over the use of sodium benzoate as a preservative in condiments. Harvey W. Wiley, the "father" of the Food and Drug Administration in the U.S., challenged the safety of benzoate. In response, entrepreneurs, particularly Henry J. Heinz, pursued an alternative recipe that eliminated the need for that preservative.
Prior to Heinz (and his fellow innovators), commercial tomato ketchups of that time were watery and thin, in part due to the use of unripe tomatoes, which were low in pectin. They were also less vinegary than modern ketchups; by pickling ripe tomatoes, the need for benzoate was eliminated without spoilage or degradation in flavor. But the changes driven by the desire to eliminate benzoate also produced changes that some experts (such as Andrew F. Smith) believe were key to the establishment of tomato ketchup as the dominant American condiment.
Until Heinz, most commercial ketchups appealed to two of the basic tastes: bitterness and saltiness. But the switch to ripe tomatoes and more tomato solids added umami, and the major increase in the concentration of vinegar added sourness and pungency to the range of sensations experienced during its consumption. And because the elimination of benzoate was accompanied by a doubling of ketchup's sweetness, a balanced stimulation of all five types of taste sensations resulted.
In the United States, the Food and Drug Administration has prohibited the use of the word "ketchup" on product labels unless the product conforms to a set of strict guidelines. All products marketed as ketchup in the United States must be thickened only with tomato solids, and the viscosity of the sauce must be within a very narrow range. The nutrient content of the sauce is also tightly regulated.
In the past, ketchup was produced from fresh tomatoes after harvesting. Vacuum evaporation made it possible to turn tomatoes into a very thick tomato paste that is easy to store at room temperature. This enables a factory to produce ketchup throughout the year.
In October, 2000, Heinz introduced colored ketchup products, which eventually included green, purple, pink, orange, teal, and blue. These products were made by adding food coloring to the traditional ketchup. As of January 2006 these products have been discontinued.

Ketchup has been shown to provide significant health benefits but many argue that these benefits are offset by the food's salt and sugar content. Ketchup has been found to be a beneficial source of lycopene, an antioxidant which may help prevent some forms of cancer. This is particularly true of the organic brands of ketchup. In fact, organic brands were found to contain three times as much lycopene as non-organic brands. Ketchup, much like marinara sauce and other cooked tomato foods, yields higher levels of lycopene per serving because cooking makes lycopene in tomatoes more bio-available.
There is a better technique that avoids both the thixotropic effect and the need for an inefficient tool. Known widely among caterers, it involves inverting the bottle and forcefully tapping its upper neck with two fingers (index and middle finger together). Specifically, with the Heinz Ketchup product, one taps the 57 circle on the neck. This helps the ketchup flow by applying correct G-forces. Another solution to this problem appeared with the introduction of plastic squeeze bottles. More recently, Heinz and others have introduced an "upside-down" bottle, which further remedies the problem by keeping the remaining ketchup at the mouth of the bottle. These bottles are also fitted with a control valve in the nozzle designed to eliminate the build-up of ketchup in the cap after use.
The spelling catsup seems to have appeared first from the pen of Jonathan Swift, in 1730.
The exact Chinese characters used to represent the word kôe-chiap have been disputed, with two primary theories as to the word's original Chinese orthography:

Merriam-Webster also states that "ketchup" derives from a word meaning "fish sauce", but identifies the source language as Malay.
