You would need superheated water at 105 °C to 110 °C to dissolve 130 g of glucose in 100 mL of water.
It is difficult to find data on the solubility of glucose as a function of temperature.
Here is one graph from http://www.isco.com/WebProductFiles/Applications/105/Application_Notes/Aqueous_Solubility_at_High_Temperature.pdf
And here's another from http://www.isasf.net/fileadmin/files/Docs/Arcachon/posters/p20-P143%20King%20Proceedings_ISSF_2009_carbohydrates_solubilities.pdf
In each case, it appears that a solubility of 130 g/100 mL or 1300 g/L is not reached until a temperature of about 105 °C to 110 °C.
