ELISA Systems Mustard Seed Protein Residue kit was released in June 2007. A polyclonal rabbit antiserum was raised and used to develop a quantitative sandwich ELISA that has been demonstrated to detect mustard seed protein from aU three species of mustard plants S. alba, B. nigra, and B. juncea [5]. The detection limit of the kit has been shown to be less than 0.5 ppm (mg/kg) of soluble mustard protein, which corresponds to mustard seed concentrations below 3.4ppm S. alba, below 4.9 ppm B. nigra, and below 5.5 ppm B. juncea. An example of a calibration curve is presented in Figure 23.1. Cross-reactivity studies were conducted on full-strength extracts from 50 plants and other common foods, and cross-reactivity was observed only with rapeseed (Canola), Brassica napus. This cross-reactivity was approximately 50%, but purified canola oil did not cross react. 

KR returns to the clinic for follow-up 6 months later. She continues to grow along her growth curve. She has started the DHA supplement but sometimes forgets to take it. She takes 100 mg about four times per week. Canola oil has been added to her diet but only about two teaspoons... 

The temperature dependence of the DPH anisotropy in canola oil and paraffin oil is presented as curves a and b, respectively, in Figure 7. Canola margarine was not included because it crystallized at 40°C, the matrix became opaque, and no fluorescence signal was detectable. To correlate viscosity to fluorescence anisotropy, the viscosity of the two oils and the fat were measured by rotational viscometry (Fig. 8) at temperatures above 50°C to ensure that all fat was melted. Samples were equilibrated at 50°C for 6 h prior to measurements to destroy any thermal history of the system. AU samples displayed Newtonian rheological behavior. 

The temperature dependence of the DPH fluorescence lifetime in paraffin oil is shown in Figure 9. The lifetime values derived from this experiment were used in the derivation of Perrin equations for all systems [Eq. (16)]. Perrin plots for canola oil, canola margarine fat, and heavy white paraffin oil are shown in Figure 10. These curves can be used for the determination of viscosities at different temperatures by measuring steady-state anisotropies. The correlations obtained are presented in Table 1.

The same shortenings were analyzed with the compression test, and the results are shown in Figure 8. Curves 1, 2, and 3 represent those of all-purpose shortenings. Curves 1 and 2 are for soy-palm and 3 for soy-canola-palm. All...
