Description

A kind of freshness detection device based on egg outer surface frictional force
Technical field
The present invention relates to egg detection technique field, specially a kind of freshness inspection based on egg outer surface frictional force Measurement equipment.
Background technique
Egg is a kind of full of nutrition and by the favorite food of many people, for human body, the protein product of egg Matter is splendid, is only second to breast milk, easily absorbs for body, and utilization rate is up to 98% or more, and nutritive value is very high.Contain in egg simultaneously Vitamin and microelement necessary to several mineral materials and other human bodies, are the good benefit of children, old man, puerpera etc..
But egg is as a kind of biological food, because the resting period longer leads during production, transport and storage Egg is caused rotten situation occur, egg is put over time, and egg liquid can go bad, and cannot eat.Especially summer, egg are rotten It obtains faster.And the opaque eggshell in one layer of egg outer surface causes people's naked eyes that can not identify whether egg is corrupted.
In the prior art, detection is typically scanned to egg by optoelectronic device, by comparison spectrum to It identifies egg internal component, judges the freshness of egg, but such equipment judges whether egg is fresh, firstly, technique Complexity, cost is also relatively high, in addition, such detection device the proficiency of worker is required to have to it is very high.In some In small business, so high testing cost can not be undertaken at all.
And study found that the antibacterial substance that fresh egg outer surface has one layer of naked eyes that can not see, as the time is lost, This layer of antibacterial substance can disappearance slowly, after antibacterial substance disappears, the outer surface of egg can be very smooth shinny.Therefore new Fresh egg compares older egg, and outer surface can compare coarse.Veteran can be by way of touching, to judge at present Whether egg is fresh, however such detection method, too relies on the subjective judgement of people, while being also required to certain experience It just writes, and the personnel relatively rough for skin, such judgment method error is also bigger.
Therefore the present invention provide it is a kind of according to egg outer surface antibacterial substance formed film judge whether egg fresh Equipment.
Summary of the invention
