Hi everybody.

 

It is the first time, I have written here. My english is not so good, so If I can not express myself, sorry for that.

 

I have a question and if you can help me, I'd appreciate it.

 

I make shelf life analysis of confectionery products, and use climate cabin at 30 C.

 

But I want to shorten period of shelf life test. So could i increase temperature into climate cabin?

 

Do you know how many degrees of confectinery productscan actually melt? Especially Marshmallows.

 

Thank you in advance.

The melting point of a marshmallow is 45 degrees Celsius. Marshmallows melt at such a low heat as they are mainly sugar and not very dense. But chocolate melts at around 34 degrees Celsius. I would probably keep it lower than 34.

Hi

 

My experience with bakery or confectionary products - sometimes rather complex - are not as good as in other areas (biotechnology, active ingredients in pharmaceuticals).

Arrhenius should be applicable - i.e. reaction kinetics should be pseudo first order, i.e dependent on one parameter e.g. temperature only.

Analytic should be sensitive - e.g. measurement of concentrations etc. Sensoric scaling is rough and therefor extrapolation is not really possible. Temperature steps - the large the difference the better. But in many case it is not possible (melting points of products or glass point of packaging).

 

Until now we do shelf life test for 2/3 of the proposed shelf life to set it for the first production. Shelf life test will run for the next 1/3 and additional 1/3 on top. Shelf life will be adopted acc to results.
