Hello!

I am looking for researches/publications/anything really concerning Differential Scanning Calorimetry (DSC) measurements on the glass transition temperatures in osmotically dehydrated fruits. Can anyone help me out?

Thanks in advance!

dear Sarara,

Do you hv access to a library (or money )?

PS I bet you have scanned dozens of pages in Google / Yahoo already !

Haha. Charles, I thought so too. Maybe this is why nobody has come up with a single link for SaRaRa.

@ SaRaRa,

No experience on Tg for dehydrated fruits. But I did some reading on Tg for dehydrating fruit juices.

During spray drying of fruit juices, one needs to know the Tg of the juice solids to adjust the spray drying temperature to get the optimum yield.

Too bad we do not have a DSC on hand and the Tg is mainly based on literature...

It's sort of off-topic, but maybe you might find something useful from the attachements?

Found a link to free jounals that might help you find what you need:

Happy searching!

Hahaha! :D
Yes I actually have! :P
...and yes I do have access to the library of the technical educational institute I graduated from but its really, but REALLY far!
Yeh me iz lazy :P

Thank you for your help guys!

Dear AS NUR,

Thks for some fascinating chemistry although a bit over my head in places.

@Sarara - Is this material a potential Ch.1 of a Master's thesis by any chance ?

[SaRaRa]

Very nice info! Thank you AS NUR! :)

@ Charles: Hahaha yes but its not mine :)
Its just something one of my teacher is working on right now with some students (I suppose) and she asked me to find some info about it (because I kinda have some more free time now). So far I did find some stuff but not muuuuch. Thats why I thought of asking here!

Hi SaRaRa,

I use a DSC regulary for measurements on polymers.
What Tg temparature do you think off?

Hi there

My name's Irene Samson & I have done a lota work with DCS and glass transition temperature for my masters thesis and there are 2 papers published, they are:

1. The measurement of the glass transition
temperature of sucrose and maltose solutions
with added NaCl
Paul A Kilmartin,1* David S Reid2 and Irene Samson1
1Department of Chemistry, The University of Auckland, Private Bag 92019, Auckland,

2. Dielectric properties of frozen maltodextrin
solutions with added NaCl across the glass
transition

Hello people!
Thank you for your answers!

@ okido: Well I am searching actually anything concerning this topic, not something specific.

@ isamson: thank you very much! I will check them out! :)
