Is it true that mixing lime with sugar gives a sticky substance? if so, why? does it have anything to do with aldol condensation of claisen-schmidt condensation?

to find out, I ran a small experiment mixing plaster-grade unslaked lime powder with nearly (room temperature)saturated colorless transparent sugar solution prepared with food-grade sugar and tap water. I found out, the substance gradually turns into chocolate-brown color within a matter of few days if the lime powder can be kept into suspension state. to speed up reaction, I put in under direct sunlight, (slightly warmer than ambient), enclosed in a 250 ml transparent plastic beverage bottle (possibly made of PET). the lime volume was about 1/10th of solution volume. when the lime was precipitated , the solution color and consistency was comparable with honey.

This results invoked me some more questions

• why is honey yellow? are all color-additive free C-O-H compounds are visibly colorless except for those molecules with aromatic chromophore group and/or conjugated diene system?
• can strong alkalies catalyze aldol or claisen-schmidt type condensation to yield aromatic or conjugated product from polyhydroxyaldehyde or polyhydroxyketone under utterly uncontrolled reaction as above? Does UV or visible light play any role in such reaction?
