Ketchup

Celery Seed. Celery spice is the dried ripe fmit of y piumgraveolens L. (UmbeUiferae) a biennial, sometimes aimual, herb native to southern Europe and grown extensively in India, China, Mexico, and the United States. The seed is 0.42 cm long and brown. The odor of the seed is characteristic and warm and the taste somewhat bitter. It is used in tomato ketchup, sauces, soups, pickles, pastries, salads, and certain cheeses. 

Heat Exchangers Using Non-Newtonian Fluids. Most fluids used in the chemical, pharmaceutical, food, and biomedical industries can be classified as non-Newtonian, ie, the viscosity varies with shear rate at a given temperature. In contrast, Newtonian fluids such as water, air, and glycerin have constant viscosities at a given temperature. Examples of non-Newtonian fluids include molten polymer, aqueous polymer solutions, slurries, coal—water mixture, tomato ketchup, soup, mayonnaise, purees, suspension of small particles, blood, etc. Because non-Newtonian fluids ate nonlinear in nature, these ate seldom amenable to analysis by classical mathematical techniques. 

Hot-Fill Applications. A growing market for blow-molded containers is the so-called hot-fill market. This covers such items as tomato ketchup, pasteurized fmit juices, and salad dressings that are packaged while sti11 hot. The PET blow-molded bottie suffers from its relatively low T (70°C) which results in severe bottie distortion if the temperature of the contents approaches T (the maximum fill temperature is 60 65 C). A brief heat... 

Americans were eating a wide variety of artificially colored products, including ketchup, jeUies, cordials, butter, cheese, ice cream, candy, sausage, noodles, and wine. The use of the new synthetic colorants in dmg and cosmetic products was also increasing rapidly. 

The key properties here are hardness and wear resistance, ability to. stand minor knocks and dents without cracking and resistance to various domestic chemicals. These vary with type of appliance, e.g. detergent solutions are important for washing machines, while a fridge will be required to withstand fruit juices, ketchup and polishes. Good colour and appearance in white and mainly pastel shades will be expected. Corrosion resistance is required, especially for washing machines, and domestic appliances frequently have to withstand humid conditions in kitchens. 

Ketchup. The ketchup, tomato sauce, barbeque sauce type products are difficult to package. The compatibility factor is guided by consumer requirements and the expected shelf life or market pattern.

One simple yet successful technique for cleaning green, faded copper utensils, brass items, and chrome surfaces recommends the use of vinegar Pour vinegar and salt over copper surface and rub. Even black- or green-coated specimens of native copper can be cleaned with vinegar. Alternative recipes suggest lemon juice, ketchup, or even water in which onions have been boiled. Why do these remedies work ... 

Copper is a metallic element brass is an alloy or mixture of the metallic elements copper and zinc. The surfaces of copper and brass items tarnish with prolonged exposure to air, particularly in moist environments with high carbon dioxide (CO2) or sulfur dioxide (SO2) concentrations (see color Fig. 5.2.1). The compounds that form on the surface, ranging in color from black to blue to dark green, dissolve readily in acidic solutions. Vinegar contains acetic acid, ketchup contains tomatoes rich in ascorbic acid (Vitamin C), and onions contain malic acid and citric acid. All of these foods provide variable amounts of acid to dissolve the tarnish on copper surfaces. 

As is evident from Eq. (3-20) or (3-21), the Bingham plastic exhibits a shear thinning viscosity i.e., the larger the shear stress or shear rate, the lower the viscosity. This behavior is typical of many concentrated slurries and suspensions such as muds, paints, foams, emulsions (e.g., mayonnaise), ketchup, or blood. 

The quality of the ketchup that the American consumer uses on hamburgers and hotdogs is often judged by its resistance to flow. A ketchup that has a thick, flow-resistant consistency is generally considered to be of higher quality than one that flows readily from the bottle. However, this same consumer may become frustrated when the resistance to flow is so high that the ketchup does not flow in a timely manner from the bottle. The most desirable ketchup is thus the one that is judged to have a resistance to flow that is somewhere between the two extremes. 

An obvious benefit of such a system is that it can be used for flow processing and can be installed on-line . In this way large volumes can be processed as is the case in the manufacture of such items as fruit juices, tomato ketchup and mayonnaise.
