In systems where several carotenoids are involved, the absorption of each carotenoid is governed by interactions among them carotenoids compete for absorption (Furr and Clark 1997). For example, (3-carotene supplementation reduced absorption of dietary lutein and lycopene in humans (Micozzi and others 1992). Tyssandier and others (2002) found that the absorption of dietary lycopene was reduced when a portion of spinach or pills of lutein were additionally administered to the volunteers. Similarly, the absorption of dietary lutein was reduced by consumption of tomato puree or lycopene pills (Tyssandier and others 2002). Furusho and others (2000) demonstrated that liver retinol accumulation in Wistar rats was significantly reduced when a fixed amount of (3-carotene was replaced by a mixture of (3- and a-carotene, suggesting that each one of these carotenoids mutually inhibits the utilization of the other. The proportion of (3-and a-carotene in the mixture used in that study (Furusho and others 2000) simulated that of carrots. 

Potl inhibitors differ from other protease inhibitors, and from all other defense peptides mentioned thus far, in their relative lack of disulfide bonds. This means that the loop with the reactive site is not fixed, as it is in the Bowman-Birk inhibitors, yet they still form a stable fold, as shown in Figure 11. An interesting feature of some Potl inhibitors is their tendency to form stable, noncovalently bound oligomers. This has, for example, been shown for chymotrypsin inhibitor I from tomato. This peptide has a monomer weight of 8300 Da under dissociating sodium dodecyl sulfate (SDS) gel conditions. Gel filtration and ultracentrifugal analysis revealed a... 

A pressurized direct-drive concentric cylinder viscometer system (Figure 3-21) was used to obtain shear rate versus shear stress data on a tomato puree at several fixed temperatures between 76 and 120°C (Figure 3-22), and temperature versus apparent viscosity data at several shear rates on a 4% waxy rice (WR) starch dispersion during gelatinization over the temperature range 30 to 110°C (Figure 3-23) (Rao et al., 1998). The drive motor, torque unit, and concentric cylinder unit and temperature control vessel of a Haake RV2 viscometer system (Haake Inc.) were placed in a chamber (PRC) that could be pressurized to 0.2 MPa (two atmospheres). The temperature control vessel was insulated to minimize heat loss. A eopper-constantan (36 gage wires) thermocouple plaeed in the well of the inner eoneentric eylinder measured the temperature of the test sample. 

Thus, an useful general result is that the viscosity of tomato concentrates can be scaled by the factor (totalsolids) -. For example, at a fixed temperature, one can predict the viscosity 2 of a tomato concentrate having the concentration C2 from the magnirnde i of a concentrate of the same variety having the concentration c from the relationship ... 

Since the greater majority of plants still remain to be examined, the taxonomic distribution of alkaloids cannot be fixed with any certainty, and their total number and occurrence can only be guessed. About one thousand are now known, the structures of many of them being still undetermined (179). The chemistry of the flora of only a few regions of the world has been intensively studied (Australia Webb (180) Siberia Sokolov (181) ). It is estimated that 10% to 20% of all plants contain alkaloids, but such estimates are uncertain to the extent that our analytical methods often fail to detect traces. Improved methods have led to the finding of nicotine in tomatoes (182) and of alkaloids in... 

In pure-culture inoculation experiments, made by Rovira (1963), it was found that Azotobacter did not colonize the roots of lucerne, maize, tomato, or wheat to any great extent. Clostridium and a facultative nitrogen-fixing bacillus were moderate colonizers. In mixed-culture, or unsterilized soils, where competition is likely to be very intense, one would expect even less success in attempts to influence the rhizosphere population by adding foreign organisms. 

Specific Spray Conditions. The field locations, equipment used and conditions for spraying potato fields with mancozeb by fixed-wing aircraft are presented in Tables II and III. Similar data for application of mancozeb by a ground alrblast sprayer (tomatoes) and by a compressed air sprayer (home yard) are given in Tables IV and V respectively. 

If a number of substances is being maintained in fixed proportions in the process, it is better to consider them all together, enclosing them in one variable (see proposed problem 13 in Sect. 7.10). For example, if a food material (e.g., tomato juice) is to be concentrated by removing water, then all components (e.g., carbohydrates, proteins, fats) will remain together in the concentrated stream then it would be most efficient to call all of them solids and use just one variable for it all. 

Tomatine and dehydrotomatine were isolated fix)m tomato plants and separated on a C g column (A = 210nm). A 14-min 90/10/0.1- 50/50/0.1 water/aceto-nitrile/TFA gradient generated good separation. The content of leaf and green fhiit extracts were compared. Spike standards of 1-12.5 pg injected were cited [1086]. ...
