It was EpicCraft on the FTB launcher. In comparing folders a bit, it looks like it adds config files in the enviromine/customproperties folder.
I zipped up the enviromine config folder from that pack and uploaded it here,

File is safe but i understand if you dont want to download that heh, so like i said just grab the mod pack from FTB and check it out yourself.
Here is a quick snippet for comparison and you can see the config effects, this is pulled from the fluids config, you can see where the smoothie will affect temp and both affect hydration.
"Strawberry Soda" {
I:01.ID=16314
I:02.Damage=0
B:"03.Enable Ambient Temperature"=false
D:"04.Ambient Temperature"=0.0
D:"05.Ambient Air Quality"=0.0
D:"06.Ambient Santity"=0.0
D:"07.Effect Temperature"=0.0
D:"08.Effect Air Quality"=0.0
D:"09.Effect Sanity"=0.05
D:"10.Effect Hydration"=1.0
D:"11.Effect Temperature Cap"=37.0
}

"Melon Smoothie" {
I:01.ID=15280
I:02.Damage=0
B:"03.Enable Ambient Temperature"=false
D:"04.Ambient Temperature"=0.0
D:"05.Ambient Air Quality"=0.0
D:"06.Ambient Santity"=0.0
D:"07.Effect Temperature"=-0.2
D:"08.Effect Air Quality"=0.0
D:"09.Effect Sanity"=0.0
D:"10.Effect Hydration"=0.8
D:"11.Effect Temperature Cap"=34.0
}
On the flip side, it also has files that have negative affects too such as affecting hydration, for example the bigger foods will affect hydration more and what not, this is pulled from the feast file,
"Delighted Meal" {
I:01.ID=15493
I:02.Damage=0
B:"03.Enable Ambient Temperature"=false
D:"04.Ambient Temperature"=0.0
D:"05.Ambient Air Quality"=0.0
D:"06.Ambient Santity"=0.0
D:"07.Effect Temperature"=0.0
D:"08.Effect Air Quality"=0.0
D:"09.Effect Sanity"=4.0
D:"10.Effect Hydration"=-10.0
D:"11.Effect Temperature Cap"=37.0
