This invention relates to the fields of agricultural product processing and bio-feed technology, specifically to a method and application for detoxifying corn steep liquor. The method includes: subjecting a mixture of corn steep liquor, a composite color-protecting agent, and a composite catalyst to a first reaction; allowing the reaction system after the first reaction to stand in a mixture with a composite adsorbent; subjecting the mixture containing the reaction system after the stand-in reaction and a composite enzyme preparation to stand-in treatment, mixing treatment, and enzymatic hydrolysis; and subjecting the mixture containing the reaction system after the enzymatic hydrolysis and an activated composite microbial agent to anaerobic fermentation. This method employs a multi-stage chemical-enzyme-fermentation linkage process, achieving efficient detoxification of corn steep liquor while significantly improving flavor and nutrition. This method synergistically removes mycotoxins and sulfites, and enhances palatability and probiotic value through fermentation transformation of off-flavor substances and enrichment of small peptides and lactic acid. The process is simple and requires no adsorbent separation.

The present application relates to a kind of contaminated straw fast carbonization detoxification method, comprising the following steps: S1: collecting contaminated straw;S2: contaminated straw is chopped to less than 2cm;S3: chopped straw is dried to moisture content is less than 15%;S4: drying straw is carried out first fast pyrolysis and obtains carbonized straw, flue gas is handled after passing through front condensation recovery purification system by fan and is recycled in second heating device;S5: carbonized straw is carried out second fast pyrolysis and obtains detoxification carbonized straw, flue gas is handled after passing through rear condensation recovery purification system;S6: front condensation recovery purification system and rear condensation recovery purification system collect heavy metal in flue gas and reuse flue gas.The present application also relates to a kind of contaminated straw fast carbonization detoxification equipment.The present application realizes the efficient detoxification recovery of heavy metal in straw by two high-temperature fast pyrolysis, belongs to the technical field of agricultural and forestry waste resource utilization.

The invention relates to a rapeseed protein concentrate efficient detoxification production method based on ethanol washing and physical passivation, and belongs to the technical field of agricultural product processing. In order to solve the problems of incomplete detoxification and large loss of nutritional ingredients in the prior art, the invention provides a collaborative detoxification method which comprises the following steps: firstly, cleaning and flaking rapeseeds, then carrying out key physical passivation treatment, instantaneously passivating myrosinase at 110-125 DEG C, and preventing glucosinolate enzymolysis; then, ethanol is adopted to leach and extract oil, the wet meal is subjected to multistage counter-current extraction and washing with a 50-70% ethanol aqueous solution, and anti-nutritional factors such as thioglycoside, phytic acid and tannin are deeply removed at 70-75 DEG C; and finally, carrying out solid-liquid separation, secondary drying and desolventizing treatment to obtain a finished product. The method realizes detoxification in the whole process from source blocking to body removal, has high detoxification efficiency, can maximally retain protein nutrition, is safe and environment-friendly in process, and is suitable for large-scale production.

The invention belongs to the technical field of food processing, and discloses an ultrasonic-assisted detoxified bean product and a preparation method thereof.According to the method, an ultrasonic technology is combined with traditional heat treatment and enzyme treatment, toxic components in the bean product are efficiently removed, the nutritional value of the bean product is reserved, the heat treatment process is optimized through the ultrasonic technology, and the heat treatment efficiency is improved. A more efficient detoxification effect is realized at a lower temperature, the speed and the effect of the enzymolysis reaction are remarkably improved, and the loss of nutritional ingredients at a high temperature in a traditional detoxification method is avoided. Experimental results show that according to the method, the decrease rate of the trypsin inhibitor content exceeds 90%, the saponin residue is lower than 0.1 mg / g, the protein retention rate is larger than or equal to 80%, and the in-vitro protein digestibility is improved.
