A research on the effectiveness of the chip readers by using five different articles

Belgian Packaging Institute, Z. For reasons of food safety, packaging and food contact materials must be submitted to migration tests. Testing of silicone moulds is often very laborious, since three replicate tests are required to decide about their compliancy.

This paper presents a general modelling framework to predict the sample's compliance or non-compliance using results of the first two migration tests.

It compares the outcomes of models with multiple continuous predictors with a class of models involving latent and dummy variables.

The model's prediction ability was tested using cross and external validations, i. Beyond this limit the risk for false compliant results increases significantly, and a third migration test should be performed.

The result of this latter test defines the sample's compliance or non-compliance.

Propositions for compliancy control inspired by the current dioxin control strategy are discussed. This is NOT a study. This is an outline of the testing frame work use for silicone leachate tests.

Its interesting if you want to get into how silicone is actually tested.

It does state clearly that silicone testing is laborious and requires a three-phase process which could explain why so many products that have been manufactured are now being shown to be insufficient or not up to manufacturer claims.

Characterisation and migration properties of silicone materials during typical long-term commercial and household use applications: Simatb - Pages Abstract: The main question was whether a significant degradation or even breakdown of the silicone elastomer could take place yielding enhanced migration of dimethyl siloxanes.

Oligomeric dimethyl siloxanes are reaction side-products of the polymerisation process and despite their origin as so-called non-intentionally added substances NIAS were found to be the by far most dominating constituents of the overall migration.

Furthermore, the influence of long-term thermal stress on the functionality of the elastomer was proven. No formation of migrating siloxanes beside the initial amount in the new, unused moulds could be observed.

The loss of extractable siloxanes of the used compared with the new moulds was compensated by an uptake of fat and other lipophilic food constituents.

The release of volatile organic compounds VOC decreased from 0. GC-MS analysis of evaporating volatile compounds showed only cyclic oligomers for the new moulds but exclusively incorporated food components for the heavily used moulds.

The physical properties of the silicone moulds remained almost constant during the experiment; no limitations in function due to the repeated thermal stress were observed.

Similar results were obtained for baby teats under household conditions of use: Because milk is only a weak extracting agent no significant changes in the amount of extractable siloxanes between new and used teats could was seen. Again an uptake of fat was seen and the amount of VOC decreased from 0.

Yes there is leachate from silicone - particularly new products though it is apparently in line with what is considered acceptable. Determination of siloxanes in silicone products and potential migration to milk, formula and liquid simulants Conducted By: No linear siloxanes were detected in the silicone nipple samples analysed.🔥Citing and more!
