The disclosure discloses a high-flux and ultra-sensitive detection dot array enhancement chip, and belongs to the field of food safety detection. In the disclosure, single-layer Au nano-particles are chemically bonded onto a hydrophilic substrate, an Au nano-material is naturally deposited in holes of the chip under an electrostatic adsorption action, and a regular dot array is formed. Au particles distributed in the holes are separated with a particle surfactant (CTAB) to form plasma gaps so as to enhance the self-assemble of Au nano-particles distributed on hot-spots for a long range effect, thereby improving the sensing signal in detection efficiency and sensitivity of the chip.

A fermented beverage and a preparation method are disclosed. The method uses ripened fruits and/or vegetables as raw materials. The method includes performing a natural ripening on a fruit and/or a vegetable at 15° C. to 30° C. for 5 days to 10 days to obtain a ripened fruit and/or vegetable; and inoculating lactic acid bacteria into the ripened fruit and/or vegetable, and performing a fermentation for 10 days to 30 days at 15° C. to 30° C. to obtain the fermented beverage. After 23 days of fermentation, the fermented beverage has a total flavonoid content up to 0.5 mg/mL to 2.0 mg/mL, which is beneficial to human health, a pH of 3.2 to 3.8 and a total titratable acidity of up to 12 mg/mL to 18 mg/mL. The fermented beverage requires a short fermentation cycle, which is beneficial to industrial production.

Fermented beverage and preparation method thereof

The present disclosure belongs to the technical field of analytical chemistry, in particular to synthesis and application of a nanomaterial for removal of patulin (Pat). The present disclosure adopts 2-Oxin as a substitute template, AM as a functional monomer, and synthetic FeO4@SiO@CS-GO magnetic nanoparticles as a carrier, for preparing a magnetic MIP specific for Pat adsorption by surface imprinting. The addition of FeOmakes the finally prepared molecular imprinted adsorbent material magnetic, thereby facilitating separation of a material from a matrix, eliminating complicated operation steps such as filtration and centrifugation, and facilitating recovery of materials.
