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 disinfecting method based on an ultrasonic cooperated micro-nano bubble technology, and belongs to the technical field of food processing. The egg cleaningand disinfecting method mainly comprises the steps that (1) a hydrogen peroxide disinfection solution with the concentration of 0.1-2.0% is prepared by using sterile water, and 2-12% of citric acid and 1-10% of an anionic surfactant are added to the disinfection solution to serve as a synergist; (2), a disinfection agent is diluted to make the content of the cleaning and disinfection agent in thesystem be 200-250 mg/L, the disinfection agent is added to an ultrasonic cleaning tank to a set ultrasonic parameter, and the constituents of the disinfection solution are homogeneous and stable; (3), eggs are immersed into the disinfection solution, and parameters of an ultrasonic device and a micro-nano bubble generator device are adjusted to clean and disinfect the eggs. The rate of killing microorganisms on the surfaces of the fresh eggs treated by using the method reaches 99.99%, the disinfection time is short, the egg cleaning and disinfection efficiency is effectively improved, and theproblem is solved that when the eggs are soaked into the disinfection solution for a long time, secondary contamination is caused. The invention further provides the composite disinfection solution special for cleaning and disinfection of the 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 ...
