The invention discloses preparing fluorescent carbon quantum dots from alternanthera philoxeroides and the use thereof for detecting a food additive lemon yellow. The method comprises the following steps: a, weighing alternanthera philoxeroides powder and thiourea in a mass ratio of 1: 1, adding water, carrying out stirring, and carrying out transferring to a reaction kettle; b, putting the materials into a drying oven, and performing reacting at a set temperature; c, after the reaction is finished, naturally cooling to room temperature, carrying out suction filtration to obtain a carbon quantum dot solution, carrying out dialyzing, carrying out rotary evaporation, and carrying out drying to obtain carbon quantum dot powder. The prepared fluorescent carbon quantum dot for detecting lemon yellow belongs to a turn off type, and has the advantages of high sensitivity, strong stability, good selectivity, low cost and the like. The optimal concentration range of linear detection is 7.8-125 [mu]mol/L, the detection limit is 0.45 [mu]mol/L which is far lower than the detection limit 187.14 [mu]mol/L provided by the national standard GB/T 5009.35-2003, and the method can be used as a convenient and accurate lemon yellow rapid detection method.

The invention relates to a hydrolysis saccharification process of alternanthera philoxeroides. Metal substance pollutants (iron, cobalt and nickel) in alternanthera philoxeroides raw materials are absorbed by adopting magnetic force, so that subsequent mechanical abrasion and contents of metal ions in treating fluid are reduced, and a good fermentation condition is created for detoxification of selected cupriavidus metallidurans; then solid-liquid separation is realized by adopting an extrusion method, hydrolysis on lipids and protein contained in liquid-state materials is carried out by adopting an NaOH solution, and then hydrolysis treatment is further carried out by adopting trypsase, so that the hydrolysis is more completely carried out; meanwhile, extruded solids are dried and crushedand then dropped into a sulfuric acid solution to carry out acidolysis; through electrorheological fluid shear stress effect treatment, cellulase is then added and enzymatic treatment is carried out,so that the effect is good and energy consumption is low. According to the hydrolysis saccharification process of the alternanthera philoxeroides disclosed by the invention, the raw material treatment efficiency is improved to the maximum extent, and finally, saccharified hydrolytic solutions rich in nutrient substances such as glucose, amino acid, small molecule chain lipids and the like are obtained, so that the glucose content is high, and the glucose can be conveniently supplied for further fermentation, and the production efficiency is improved.
