Description
Technical field
The present invention relates to the testing equipment field of the contact area of food contact material, is not advised more particularly to one kind measure
Then device of contact area of food contact material and product and preparation method thereof and methods for using them.
Background technology
Food contact material and product refer to that the food such as the tableware used, packaging for foodstuff, kitchen tools can be contacted in daily life
Product equipment or articles for use.As people require more and more higher to cuisines color, smell and taste, packaging for foodstuff or tableware etc. are used as food consumption
Added value it is also more and more concerned.Packaging for foodstuff or tableware, which are designed to be more to do things creatively, can more attract the eyeball of consumer,
Then, many laboratory practitioners can meet various unduplicated when the migration amount for doing food contact material and product is tested
The areal calculation problem of irregular food contact material and product.
Such issues that typically by establishing model, using mathematical logic method calculate.Relatively regular and symmetrical tableware can
To calculate surface area by modeling and mathematics logical method, this needs laboratory technician to have powerful mathematical logic and calculates energy
Power.But for irregular tableware calculating contact area, it is difficult to establish model, and the workload to be calculated is big, during consuming
Between and energy, reduce operating efficiency, can not in the case of can only be rough estimation.National standard is to such irregular food contact material
Material or product are also without suitable computational methods.And according to national standard GB 5009.156-2016《National food safety standard food
Contact material and product migration experiment preprocess method general rule》In 7.3 flat articles areas calculating, but require flat articles
It is the circular port of rule one relatively；Product area assay method citing of different shapes is provided in 7.6, with reference to Appendix D, and only
Only it is four kinds of chopsticks, feeding bottle cap, soup ladle, suction pipe irregular tablewares, how other irregular tablewares are handled, and this standard does not have
Provide method.
For the new things occurred in recent years, for novel eccentric tableware, national standard to the contact area of such sample how
Calculating is to be not kept pace with the speed of tableware renewal, when the experiment of migration amount is done, contact area of the national standard to this dishware
It is no suitable processing mode.There is paper to show that can build mathematical modeling goes reasoning, but that is simply theoretical, can not
Promoted in laboratory, if by building mathematical modeling, if the mode of reasoning from logic solves area, each sample treatment is got up
It is infeasible just like the workload of a project.
And for the practitioner of laboratory, how to calculate the method for irregular food contact material and product is a problem,
So far, cumbersome measurement and calculating process can also be replaced without a kind of intuitively method of simple possible.Such as national standard
GB 5009.156-2016《National food safety standard food contact material and product migration experiment preprocess method general rule》Phase
GB/T 5009.156-2003 are modified, add " sample contacts area ", " adding Appendix D ", Appendix D is four kinds of spies
The product area assay method example of different shape, such as four kinds of chopsticks, feeding bottle cap, soup ladle, suction pipe irregular tablewares, are not represented
Property, it is to be difficult to meet ever-changing, the measure of omnifarious irregular tableware, and calculation formula complexity is, it is necessary to measure more
Individual data, multistep calculate, or even modeling type analysis, and the mathematical formulae used is more, bad memory, it is also difficult to forms calculating side
Method.How to solve the problems, such as the areal calculation of irregular food contact material and product, be exactly a difficult point always for many years, and
And this process uses substantial amounts of mathematical computations, or even modeling type analysis, process is quite cumbersome, and the mathematical ability to experimenter is one
Test.
How abstract numerous and diverse mathematical computations mode could be solved the problems, such as, be grasped by the in kind of simple, intuitive
Make, open-and-shut to provide data, the device of the application is the laboratory first-line staff for being engaged in food contact material inspection for many years
One summary of years of work experience, can solve this problem, cope with shifting events by sticking to a fundamental principle, various irregular tablewares, can use
This device goes measure to provide data.Checkability is improved, relatively much lower is required to the computing capability for testing practitioner.
The content of the invention
