I’m putting together some notes related to using sugar in beer, specifically for making Belgian candi sugar, candied ginger and other things…

Some temporary notes while researching inversion and hydrolysis of sucrose:
237 for 20 minutes to invert the sugar
add the cream of tartar, bring to 260
add the DAP, boil 260-275 for 20 mins
maintain the 260-275 range for the entire boil
only raise to 300 at end to reach hard crack stage
never go about 305 (avoid 320)
avoiding caramelization
fructose, 110C / 230F
glucose, 160C / 320F
sucrose, 160C / 320F
cane sugar (sucrose) inverts and becomes glucose/fructose
at 237, the fructose will caramelize, the glucose won’t
glycolysis is turning fructose into glucose

hydrolysis 100C-128C / 212-262F
2-6% nitric acid, 0-300 minutes
xylose, glucose, arabinose + acetic acid, furfural
hydrolysis
0.3mol cane sugar, 0.1mol HCl, 1000g water
118.4F, for 20 minutes, 32% of sugar is hydrolyzed
40-45C / 104-113F to avoid HMF production (hydroxy-mehtyl-furfural) associated with color formation
