Embodiment 1
[0031] The method of the present invention is applied in chili powder.
[0032] Firstly, a composite material of polypyrrole-wrapped magnetic ferric iron tetroxide was synthesized, and the specific synthesis steps were as follows: Synthesize magnetic Fe by solvothermal method 3 o 4 ; 1.0 g magnetic Fe 3 o 4 , 9.1 g FeCl 3 ·6H 2 O and 100 mL of deionized water were added to a 250 mL flask, shaken at 25 °C at 150 r / min for 3 h; then 20 mL of SDS (5.85 wt%) and 0.5 mL of pyrrole monomer were added, and continued to shake for 12 h; then The obtained material was washed successively with water and ethanol until the supernatant was clear, and dried in a vacuum oven at 60 °C for later use.
[0033] Without magnetic solid-phase extraction: Weigh 1.0 g of chili powder into a 10 mL centrifuge tube, add Sudan Red 1 standard (0 μg / g, 6 μg / g, 5 μg / g), 6 mL of n-hexane, shake by hand Let it stand for 1 min, take the supernatant and dry it with an ear suction ball / hair dryer, and detec...
Embodiment 2
[0039] The method of the invention is applied to substrates such as chili oil, spicy sauce, strawberry jam, and soft drinks.
[0040] The sample processing procedure for each matrix is as follows:
[0041] Chili oil: take 1.0 g of chili oil, add 6 mL of n-hexane, shake by hand for 1 min to mix well, let stand, and take the supernatant as the sample solution;
[0042] Spicy sauce: take 1.0 g of spicy sauce, add 6 mL of n-hexane, shake it by hand for 1 min, let stand, and take the supernatant as the sample solution;
[0043] Nongfu orchard mixed fruits and vegetables: Take 1.0 g of beverage, add 6 mL of n-hexane / acetone (4 / 1, v / v), shake by hand for 1 min to mix well, let stand, and take the supernatant as the sample solution;
[0044] Fruity Juice: Take 1.0 g of the beverage, add 6 mL of n-hexane / acetone (4 / 1, v / v), shake it by hand for 1 min, let it stand still, and take the supernatant as the sample solution;
[0045] Tomato paste: weigh 1.0 g tomato paste, add 1 mL H 2 ...
