Embodiment 1
[0031] Use a combination of manual and mechanical methods to remove damaged and small cracked eggs and old eggs;
[0032] Use flowing water with a flow rate of 0.08m / s to 0.10m / s to wash away the feces, weeds, feathers, soil, etc. that are easy to remove on the surface of the eggshell. The cleaning time is 60s to reduce the subsequent disinfection and sterilization load;
[0033] Absorb 0.83 mL of 30% hydrogen peroxide, and prepare 0.5% hydrogen peroxide disinfectant with 50 mL of sterile water;
[0034] Add 2 g of citric acid and 5 g of disodium hydrogen phosphate to the disinfectant in sequence, dilute the prepared disinfectant stock solution at a ratio of 1:1000, place the compound disinfectant in an ultrasonic cleaning tank, set the ultrasonic temperature to 20°C, and ultrasonically The power is 50W, and the ultrasonic time is 20s, so that the components in the disinfectant are uniform and stable in the hydrogen peroxide system.

Abstract
The invention relates to an egg cleaning and disinfection method based on ultrasonic and micro-nano bubble technology, which belongs to the technical field of food processing and mainly includes: 1) preparing a hydrogen peroxide disinfection solution with a concentration of 0.1-2.0% with sterile water, and feeding it to Add citric acid 2-12% and anionic surfactant 1-10% as synergists to the disinfectant; 2) Dilute the disinfectant so that the cleaning and disinfectant content in the system is 200mg / L-250mg / L, and add it to ultrasonic cleaning Ultrasonic parameters are set in the tank to make the composition of the disinfectant uniform and stable; 3) Soak the eggs in the disinfectant, adjust the parameters of the ultrasonic device and the micro-nano bubble generator device, and clean and sterilize the eggs. The sterilization rate of microorganisms on the surface of fresh eggs treated by this method reaches 99.99%, and the disinfection time is short, which effectively improves the cleaning and disinfection efficiency of eggs and avoids the problem of secondary pollution caused by eggs soaked in disinfectant for a long time. At the same time, the invention provides a special compound disinfectant for cleaning and disinfecting eggs.
Description
technical field [0001] The invention provides an efficient egg cleaning and disinfection process, mainly relates to an egg cleaning and disinfection method based on ultrasonic collaborative micro-nano bubble technology, and belongs to the technical field of food processing. Background technique [0002] Affected by traditional consumption concepts, my country's egg consumption is still dominated by fresh eggs, accounting for about 93% of egg consumption, with relatively little deep processing. At present, most of the eggs sold in the market have not been cleaned and disinfected or have only been cleaned briefly. There are a large number of microorganisms on the surface, which seriously affects the quality of eggs and poses a threat to human health. Eggs are usually contaminated by microorganisms in two different ways, namely the vertical transmission of the hen's ovary and the lateral transmission of microorganisms from the external environment penetrating into the eggshell ...
