The major source of lycopene is tomato products but it also occurs in water melons, guavas, pink grapefruit, and in small quantities in at least 40 plants.14 The structure of lycopene is shown in Fig. 8.2. It is a long chain conjugated hydrocarbon and its structure suggests that it would be easily oxidized in the presence of oxygen and isomerized to cis compounds by heat. Both of these reactions occur in purified solutions of lycopene but in the presence of other compounds normally present in tomatoes, lycopene is more stable. Actually the absorption of lycopene in the human gut is increased by heat treatment probably because the breakdown of the plant cells makes the pigment more accessible. Preparations from tomatoes are widely used in pizza, pasta, soups, drinks and any product compatible with the flavor and color of tomatoes. 

As much as your taste allows, use colorful, rich spices as a sprinkling on sauces or meals prepared in a pot, such as pasta and tomato sauce. Curry powder, turmeric, cumin, and cayenne pepper, for example, not only lend terrific flavors and pleasant colors but also... 

Products and Uses An ingredient added to peanut butter, cereals, bread stuffing, flour, grits, commeal, pastas, and bread products. Occurs naturally in milk, eggs, and organ meats. Used as a color additive, dietary supplement, and nutritional supplement. 

Kumkum, a turmeric-based paste applied topically, has been associated with cases of dermatitis (Nath and Thappa 2007). Cases of contact urticaria from the compounds curcumin and tetrahydrocurcumin have been reported (Fischer and Agner 2004 Lamb and Wilkinson 2003 Liddle et al. 2006 Thompson and Tan 2006). Contact dermatitis with positive patch test for turmeric was reported in a spice shop worker routinely exposed to spice powders (Goh and Ng 1987). Similarly, contact dermatitis was reported in a pasta factory worker exposed to curcumin food coloring (Kiec-Swierczynska and Krecisz 1998). Two cases of contact dermatitis were reported in individuals using a topical ointment containing turmeric. Patch testing of both individuals indicated a sensitivity to both turmeric and curcumin (Hata et al. 1997 Sakurane et al. 1999). 

Features Butyl glycol-free, low solvent content, for pigment pastas, deflocculates inorganic/organic pigments, very good color strength development... 

A form of sap green is described in the Paduan MS Ricette per Far Ogni Sorte di Colore (late sixteenth or early seventeenth century cf. Merrifield, 1849) 31. How pasta verde is made. Take the grains or berries of the buckthorn [. v.] when they are quite ripe, and this will be about the end of September let them soften for 7 days in a vase with water in which roche alum has been dissolved in the proportion of 1 oz of alum to 6 of the berries, and boil it well until nearly half the water is consumed then cool it, strain through a hnen cloth, put the part that is strained into pigs bladders, and dry them in the sun or smoke and this is called pasta di vesicha . 

A child s brightly colored pinwheel spinning in the wind creates an irresistible urge to discourse on steam turbines. A pot of pasta boiling over on our stove is the perfect incentive to deliver a lecture, which no one wants to hear, detailing foam-induced flooding in packed towers. Suntanned skin is the perfect example illustrating the power of radiant heat transfer. 

AWB No.l durum consists of selected wheat varieties with vitreous, amber-colored kernels with a minimum protein of 13%. The semolina has high levels of stable yellow pigment and high water absorption, making it ideally suited to the production of a wide range of high quality wet and dry pasta products and couscous. 

The color of refined wheat flour (AACC Method 14-30) or semolina is generally performed in an Agtion colorimeter operating in the green mode (546 nm). The sample (20 g) is mixed with 25 mL distilled water for 2 min in order to enhance color formation. Next, the slurry is read in the colorimeter that was previously calibrated with disc standards 0, 63, 85, and 100. Similar assays (AACC Methods 14-21 and 14-22) are also used to measure pasta and noodle color. The NIRA can be also calibrated to determine color.
